    compat-api.h too early so we do not remove them. Instead, move the
    avoidance inline.

    sna: Use physical output size from the kernel
    
    We have a conflict between Xorg and the kernel, once again, over the
    meaning of the EDID. Since the kernel supplies us with the physical size
    of the connector, let's place the burden of trust on the kernel and
    ignore the quirky behaviour of Xorg.

    sna: Restore TearFree operation after switching everything off
    
    We give up on TearFree if we ever see an error whilst page flipping (in
    the hope that we can keep displaying via direct use of the scanout).
    With the advent of MST, this can happen simply by the user unplugging a
    dock causing connectors to disappear and if we flip before we see the
    uevent telling us which outputs are disabled, we get an error.
    
    So, lets try and re-enable TearFree on the next opportunity, when all
    the outputs are off and we can rebuild the shadow buffer.

    sna: Don't skip migration-to-GPU for TearFree
    
    In 46caee86db0f ("sna: Fix reporting of errno after setcrtc failure"),
    the intention was to avoid reporting a fail to migrate whilst wedged for
    a simple copy from the frontbuffer to TearFree's shadow buffer. However,
    by skipping the migration, we never flushed any dirt from the CPU buffer
    prior to doing the TearFree flip.

    The pending back buffer is only the pending copy, the actual info->back
    stores the client's view of the current back buffer which may be more

    the pending to do the normal swap, then free the resultant back (which
    may have been exchanged with the front), before restoring the client's
    current back buffer.

    placement logic, we then want to pretend that Skylake has a higher
    GT-equivalence.

    sna/dri2: Prevent starting a swap chain for a decoupled Pixmap
    
    When a Window is resized, a new Pixmap is attached to the Window and the
    DRI2 buffers invalidated. However, the client may have requested a swap
    before it is notified of the resize and so we have to discard the stale
    swap. In doing so, we do not want to start a swap chain as it references
    the wrong frontbuffer and causes dire confusion when we start swapping
    for real.

    sna/damage: Prevent freeing a NULL damage marked as all-damage
    
    After an allocation failure, we may mark a NULL damage pointer as being
    all-damaged. This works on the whole as most places we only ask whether it
    is all or not damaged, and if we do a partial fallback we should just
    then migrate the whole pixmap. However, we tried to destroy the NULL
    damage pointer, and crashed.

    sna: Avoid handing back a cached pinned batch
    
    A few places hold on to the request->bo as a means for checking the
    fence completion. This means that it can have an elevated refcnt and so
    we have to be careful to double check that our cache of batch buffers
    not only are idle, but also not being used by anybody else. For example,
    in the DRI2 code, it can happen that the fence is shared between two
    windows and therefore the second window thinks that it's fence is still
    busy as the first issues a new request touching the old fence.

    sna: Allow pipes to be manually assigned to ZaphodHeads
    
    Assigning pipes to a driver instance is hard as not only do we have a
    limited number (so choosing which instances should share CRTCs requires
    user intervention) but also some pipes are limited by hardware to
    certain outputs and certain modes (and we do not have the full knowledge
    of the future configuration to be able to determine where to assign the
    CRTC). As usual, when there is no clear answer, punt it to the user.
    
    This expands the ZaphodHeads option to include an optional
    comma-separated pipe list followed by a colon before the output list,
    e.g.

    sna: Prevent infinite recursion on udevless RRGetInfo()
    
    As summarised by Mark Kettenis:
    
        Unfortunately commit 2c08d72393e4c8ddf5926571b087459aaa225cb1 that
        was made to resolve this bug introduced infinite recursion if
        polling udev for events fails (which is always the case on systems
        without udev).  The scenario is as follows:
    
        1. The server calls RRGetInfo().
        2. RRGetInfo() calls sna_randr_getinfo()
        3. sna_randr_getinfo() calls sna_uevent_poll(), which returns false
        4. sna_randr_getinfo() calls sna_mode_discover()
        5. sna_mode_discover() calls RRGetInfo()
    
        and we jump straight back to step 2, until we run out of stack
        space and crash

    sna: Hook up kernel modes on hotplug notification
    
    Some display managers, for example mutter, only use
    XRRScreenResourcesCurrent() which means they only query the existing

    modes after a hotplug event.

    sna: On hotplug events, update the output->status
    
    During the hotplug event, we query the current connector status and use
    that to trigger an output changed event to the clients. However, since
    we know the new status, we can set that on the RROutput immediately.
    Note the modelist is left unchanged, and will only be queried when the
    user requests it (though we may want to provide that in the hotplug
    notify as well).

    Suppose that the kernel reported a truncated EDID, we will eventually
    crash by trying to access invalid memory. Prevent the crash by fixing up
    the EDID header to fit the size read from the kernel (though we don't
    fixup the checksum, so strict conformance tests will still complain, but
    we won't crash.)

    After the Window resizes, we should never hand back a buffer of the old

    sna/gen4: Fix larger than 3D pipeline fills
    
    If we need to handle a FillRectangles request that is larger than the 3D
    pipeline can handle, we need to split that operation up into smaller
    chunks. This is achieved by redirecting the rendering through a view of
    the surface (offset so that coordinates are within range), or else we
    have to fallback to creating temporary surfaces.
    
    If we fail to do so, we should hit an assertion that the render target
    fits within the 3D pipeline inside gen4_emit_drawing_rectangle()

    Since the /sys/device/backlight never turned up we face an issue with

    the ACPI interface is defunct, so we need a way to distinguish them. So,
    we fallback to our priority table of known interfaces and rank them
    accordingly, first by class (platform, native, raw) and then by priority.

    Remove the driver option to delete connectors on unplugging
    
    With a MST topology change, we can find outputs may disappear. We offered
    a choice as to whether to simply disable them or completely remove them
    from the listing of available outputs.  However, clients never expected
    that their operation on any output could trigger a BadID XError (or that
    there is anyway to prevent race conditions). As such an option was made to

    If we receive an error from the pageflip ioctl, we attempt to set the

    flip also for tiling changes, or for any reason, which we also want to
    transparently handle. Rearrange the error message and flip->blit

    Currently we add fake modes to cater for applications that want to
    change the screen size but limit themselves to only those that are
    available, and do not wish to either use RandR scaling or their own. For
    widescreen panels, these 4:3 aspect ratio modes require panel fitting
    and so are less than satisfory. Since we add fake modes, let's add a few
    common widescreen modes as well (choosing the right aspect ration for
    the panel).

    uxa: Do not register hotplug without RandR
    
    When using Xinerama, RandR is automatically disabled, and calling RR
    routines will trigger an assert() because the RR keys/resources are
    not set, leading to an Xserver abort.
    
    Hotplug makes little sense without RandR, so no need to install a
    udev monitor if RandR is not available, as done in sna.

    We improve dispatch latency if after creating a command buffer we

    continue to build the next command buffer as the GPU executes and helps
    prevent needlessly using one engine for too long (i.e. sometimes we may

    sna/trapezoids: Amalgamate adjacent lines
    
    If we have two scanlines with identical extents and coverage, we can
    amalgamate them into a set of multi-row boxes. For simplicity, we only
    compare with the last box (assuming that the majority of such cases are
    "rounded-rectangles" where we have a large vertical area with no
    variation and can coalesce into a single box). This operates as a second
    pass to the scanline converter itself coalescing pure-vertical regions.

    sna: Always restore the scanout on DPMS on
    
    As we may exchange the frontbuffer whilst the outputs are hidden (DPMS
    off), when we turn them back on, unless we force the CRTCs to be
    updated, we may end up simply showing a stale scanout buffer not the
    current frontbuffer. If the two are same, it will just be a kernel
    no-op.

    This at least works when the wrapper is installed, there

    only supports vdpau. The expectation is that most software will use vaapi
    in preference for -intel, for example kodi which supports both vdpau and
    vaapi video acceleration methods. [A quick discussion with Peter
    Frühberger clarified that kodi should indeed continue to work fine and
    will not be confused if we expose an actual vdpau driver.]

    sna/gen6+: Prefer using RENDER pipeline for uncached destinations on large GT
    
    If the sampler can be cached, the RENDER pipeline can write to an
    uncached destination surface faster than main memory bw would seem to
    actually allow... Notably, performance does not drastically fall off
    with small areas compared to BLT as it once did. However, using a solid
    source (which is not yet implemented well in the RENDER pipeline) is
    still much faster with the BLT.

    sna: Differentiate between disabling CRTC and turning off DPMS
    
    xf86DisableUnusedFunctions() uses crtc->dpms(off) to disable unused
    pipes. In this case, we do want to explicitly disable the CRTC to
    release any shared state (e.g. PLLs and encoders). However, the user can
    also request for the DPMS to be disabled, either via the DPMS extension
    or the ScreenSaver. Here, we don't want to full disable the pipe as that
    incurs extra latency (and risk of failure) when switching the display
    back on. In order to distinguish the two cases, we can hook into the
    user paths and skip disabling the CRTCs.

    sna: Use VMask in 3DSTATE_PS
    
    Using dispatch mask cause hangs waiting PS Done on some cases like bug #83207,
    with larger screen or when scaling it.
    
    Also mesa uses VMask instead of Dmask for 3DSTATE_PS because in some cases
    they were getting incorrect derivatives for subspans.

    sna/gen8: Clear instancing enabled bit between batches
    
    gen8 sets the instancing bit relative to the vertex element, but we were
    clearing it for the vertex buffer. As the maximum number of vertex
    elements is fixed, just clear them all when emitting our header. Note
    that VF_SGVS is not sufficient by itself to disable all side-effects of
    instancing.
    
    Thanks to Kenneth Graunke for pointing out the change from vertex buffer
    to vertex element of the instancing enable bit.

    intel: Store pointer to struct intel_device
    
    Beware the barbarians at the gate, who invade and steal your ScrnInfoPtr
    and its Entity from underneath you. In some configurations, we lose
    access to the struct intel_device stored on the Entity after
    initialisation, causing havoc. Workaround this by storing the
    intel_device that we open in our driverPrivate.

    When using ZaphodHeads, we share the /dev/dri/card0 fd between both

    sna: Wrap rrGetInfo so that we can probe when udev is not active
    
    If the ddx is configured without udev support, we do not receive
    notifications when the MST topology is changed. This leads us to query
    the kernel for bad connectors, and so we end up reporting an unknown
    connection status for them, which the user and client often find
    confusing. However, we can not simply act upon the detection failure as
    we are too deep inside the callback chain and cannot change the arrays of
    known connectors whilst iterating over them. A neat compromise is to
    hook into the rrGetInfo call chain and poll for MST changes before we
    report back the current configuration.

    sna: Skip present unflip if the output is rotated
    
    With a rotated output and shadow buffers, we never perform the flip in
    the first place and so can ignore the unflip request as well.

    sna: Last ditch attempt to make extra large batches fit
    
    If we have unfortunate fragmentation, e.g. a cursor is pinned in the
    middle of an aperture, we can struggle to fit large objects, especially
    fenced objects on gen2/gen3. We do have one last trick up our sleeves
    that we can try: disable all of the outputs and cursors and try
    submitting the batch in as pristine an aperture as we can arrange. We
    can only hope that the subsequent restoration of the outputs is more
    conducive to future batches (and so not lead us into continual flicker).

    Don't use GetScratchPixmapHeader for shadow pixmaps
    
    GetScratchPixmapHeader should only be used for local memory pixmaps,
    as used by PutImage and friends. That's because when you free the
    scratch pixmap header, it doesn't actually free the pixmap; instead,
    it gets stuffed in pScreen->pScratchPixmap and any private data stored
    on it will be left hanging around forever.
    
    In the case of glamor, that private data includes all of the GL
    state. Using that scratch pixmap later results in glamor getting
    mightily confused as the pixmap and underlying objects do not match.
    
    Avoid this by allocating pixmap headers explicitly for this purpose.

    Correct BO allocation alignment
    
    BO allocations for pixmaps must be aligned to the tile height, but at
    some point the code was changed to align them to twice the tile
    height. This overallocates pixmaps, wasting memory, but more
    importantly, for buffers allocated by DRM and shared through DRI3, the
    stricter alignment check causes sharing to fail.
    
    From reading through the history of the code and related bugs, it
    seems like this change was part of a set of changes trying to address
    what turned out to be a kernel regression. Reverting this change
    solves the DRI3 problem and saves a bit of memory for pixmap
    allocations.

    Let the kernel send these back to us so that DIX hears about them in

    Mode setting while Present has a flip active will trigger an unflip
    before the mode is changed. The event from that unflip will not get
    processed before the mode switch is executed. Clearing the driver
    queue at mode switch time will discard the connection between the
    kernel event and the present callback so that DIX will never know that

    sna: Do not mark the pixmap as cleared in the middle of a miSpans decomposition
    
    As the miSpans will continue to overdraw the Pixmap, it's final state
    will no longer be that clear value. We need to be much more careful when
    allowing that optimisation.

    backlight: Expose interface to switch backlight on/off entirely
    
    A feature in recent kernels is to disambiguate between the meaning of
    brightness=0, between disabling the the backlight entirely or setting
    the lowest valid brightness. As such, we now have an extra knob in sysfs
    to explicitly request that the backlight be turned off.

    sna/dri2: Unhook event from draw list upon client destruction
    
    When the client goes away, we need to free its events. However, we
    have to defer the freeing of any pending event (ones currently routed
    through the kernel) for those we need to remember to decouple the event
    from the Drawable's list before they are freed.

    By marking the buffer->attachment as invalid we forced the recreation of
    the buffer on the next DRI2GetBuffers. The only small problem with that
    was that the client didn't always immediately call DRI2GetBuffers after
    the invalidation - and if they did a DRI2CopyRegion with its stale
    buffers the unfound attachment would generate a BadValue and kill the
    client. So instead of messing around with the attachment, explicitly
    recreate the buffer if we attempt to reuse a buffer of the wrong size.

    backlight: Prevent dereference of potential NULL argv
    
    Adam Sampson spotted that
    
    "It's possible (but not very sensible) to exec a program with an empty
    argument list, so argv[0] is not necessarily a valid pointer. For
    example:
    
    $ cat exec0.c
    
    int main(int argc, char *argv[]) {
        char *empty[1] = { NULL };
        execvp(argv[1], empty);
        perror("execvp");
        return 1;
    }
    $ ./exec0 /usr/libexec/xf86-video-intel-backlight-helper
    Usage: (null) <iface>

    sna: Handle rotated slaved scanouts
    
    As per the usual handling of rotated scanouts with unsupported
    rotations, we stage the drawing onto a backbuffer then rotate onto the
    crtc later. The difference here is that we must read the contents from
    the master pixmap rather than our own screen pixmap.
    
    Spotted was looking at slaved scanouts mistakenly setting the CRTC
    transformed flag.

    sna: Avoid confusing failure to flip and flipping zero CRTC
    
    During the present unflip path we blindly try to restore the original
    mode after a flip failure. However, it confuses flipping zero CRTC with
    a genuine failure. This has the result of undoing a DPMS change (e.g.
    xset dpms force dpms) under a DRI3 compositor.

    If the kernel reports that it is busy, it has not yet finished
    processing a pending flip and we have multiple CRTC queued, just wait
    for the kernel to clear its backlog before submitting the next flip. On
    the other hand, if we can just overwrite the pending flip results.
    However, the EBUSY may actually be a genuine report by the kernel of an
    error, so check for an invalid CRTC first.

    Unlike GLXWindows, GLXPixmaps are rendered directly into, without a
    staging copy. Therefore we must treat those carefully when exported and

    sna: Hook up a backlight udev monitor for external changes
    
    Changes to the backlights are notified through uevents. Hooking up a
    udev monitor to listen out for external changes to the backlight (e.g.
    through ACPI function keys, or by the user writing to
    /sys/class/backlight directly) is easier than enabling polling on the
    backlight sysfs file using X's select() mechanism.
    
    Since we listen to backlight changes, we have to be careful not to
    confuse the side-effects of disabling connectors (which may cause either
    ourselves or the kernel to turn off the backlight) with the user value.
    
    Many thanks to Alexander Mezin for the suggestion to use udev for
    tracking the notifications for external changes to the backlight.

    uxa: Restructure DRM event handling.
    
    This refactors the drm interrupt handling logic quite a bit, both to
    allow for either DRI2 or Present handlers, but also to eliminate
    passing pointers through the kernel. Passing pointers left the kernel
    holding the only reference to some internal X server data structures.
    
    After a server reset, the X server would end up using stale pointers
    stored in those structures. Using simple integers makes it possible to
    empty the queue of pending interrupt data and then ignore the stale
    kernel data.

    The kernel sometimes reports bogus MSC values, especially when
    suspending and resuming the machine. Deal with this by tracking an
    offset to ensure that the MSC seen by applications increases
    monotonically, and at a reasonable pace.
    
    Also, provide a full 64 bits of MSC value by noticing wrapping and
    tracking the high 32-bits of MSC separately.

    sna: Fix the depth/format on the temporary shadow Pictures
    
    When scaling the output, we re-render onto the scanout using a call to
    Composite, for which we create temporary Pictures. In most cases, the
    mismatching depth/format goes unnoticed, but along one particular
    fallback path, we use those to create a new Picture but the mismatching
    format results in a segfault.

    sna: Handle bad picture format/depth mismatches
    
    Scaling the output feed in an invalid picture->format/depth combination
    which causes the fallback downsampling function to explode. Whilst this
    is a bug in the higher layer, we can handle the error anyway.

    sna: Implicit release of upload buffers considered bad
    
    Currently upload buffers are automatically decoupled when the buffer is
    retired. As retiring can happen during command setup after we have
    selected which bo to render with, this can free the bo we plan to use.
    Which is bad.
    
    Instead of making the release of upload buffers automatic, we manually
    check whether the buffer is idle before use as a source to consider
    scrapping it and replacing it with a real GPU bo. This is likely to keep
    upload buffers alive for longer (limiting reuse between Pixmaps but
    making reuse of the buffer within a Pixmap more likely) which is both
    good and bad. (Good - may improve the content cache, bad - may increase
    the amount of memory used by upload buffers for arbitrary long periods.)

    sna/dri2: Update the swap type for chained flips
    
    We stash the pending flip mode into the closure, but failed to copy that
    over to the right field when continuing with a chain of flips. The
    impact was that we would fail to issue the required SwapComplete to
    unblock the clients.

    OML_sync_control:
        If there are multiple outstanding swaps for the same window, at most
        one such swap can be satisfied per increment of MSC.  The order of
        satisfying outstanding swaps of a window must be the order they were

    sna: Add an xorg.conf option for removing unused outputs
    
    Clients are not yet ready for outputs that disappear at runtime, often
    unexpectedly dieing with asynchronous BadOutput errors. A simple
    workaround is to not remove any output just yet - but allow users to opt
    in via xorg.conf, i.e.
    
    Section "Device"
      Option "DeleteUnusedDP12Displays" "true"
    EndSection
    
    The name chosen is to be consistent with the nvidia driver, which did
    MST first and encountered all of these issues first, and has also been
    adopted for -modesetting. If this is combined with persistent output
    naming (i.e. based on DisplayPort branch topology), the number of
    outputs presented to the user should be static.
    
    Instead of removing the outputs, we have to mark them detached instead
    to avoid throwing errors from the kernel.
    
    Based on the patch for -modesetting by Dave Airlie.

    also deviate in handling what hapens when that screen is off, which is
    not mentioned at all in OML_sync_control.

    sna: Do not discard damage when using the CPU to perform BLT spans
    
    The BLT paths are only taken when we know we are overwriting the target
    contents, and so we do not have to worry about reads along those paths.
    However, in terms of migrating the damage for a pixmap, we have to be
    careful in case we do not write to the full area of the composite
    rectangle, in which case we have to treat it as a read to that area and
    migrate the damage.

    was insufficient as it ended up reusing a stale cursor that was still

    with a valid cursor. Hey presto, we had a shared physical cursor, once
    again demonstrating the buggy kernel.
    
    This time, disable all cursor reuse except for the once currently
    attached to the pipe - this should prevent all sharing.

    When the shadow scanout is active, make sure we call the BlockHandler
    every time, not just when we about to sleep. This is in case we are
    swamped by clients trying to render and forgo the important step of
    ensuring that their output reaches the screen.

    sna/gen8: w/a for NULL depth buffer
    
    Instead of using a NULL type depth buffer, it is strongly suggested to
    use a 1x1 16-bit depth buffer instead (with address 0).

    sna: Remove unitialized use of 'cursor'
    
    The earlier query of cursor (simply to find out the hw size) was
    replaced by an invariant determined when the cursor was first set.
    However, not all uses of cursor->size were fixed.

    uxa: Implement minimal flushing for bdw+
    
    Based on the patch by Kenneth Graunke,
    "Several places (such as intel_cache_expire) call intel_emit_batch_flush,
    so it needs to work on Broadwell.  Sometimes the batch is empty, in
    which case current_batch may not yet be BLT_RING.
    
    The PIPE_CONTROL code has not been ported to work on Broadwell, so
    trying to do a render ring flush will hang the GPU.  It also doesn't
    make any sense to do a render ring flush, given that we never use the
    render ring for UXA on Broadwell."

    If we walk the output lists in the same order as they are listed by

    would fail when trying to obtain DRM_MASTER status). A consequence is

    Once the xserver stops running as root on kms capabable systems, we will need
    some other way to access the backlight.
    
    The approach taken in this patch moves most of the heavy lifting to a
    helper that runs with root privileges and pipes our requested brightness
    into the sysfs backlight interface. Where required, we use pkexec to
    launch the helper with the elevated privilege.
    
    v2: Amalgamate much more of the duplicate code.
        Keep the daemon and pipe alive for the lifetime of the backlight interface.

    This reverts commit 4497212307dee5e35bc6836201738a2fdb559020.
    
    Unfortunately, this simple fix does not work for UXA as DPMS is used by
    the xserver to turn off CRTCs and outputs. Since UXA does not implement
    CRTC DPMS, this commit causes us to fail to turn off outputs.
    
    The kernel has been fixed up in the meantime and that commit has been
    recommended to be backported to all stable kernels:

    sna/gen5: Flush the render cache between operations
    
    When we change the blend mode between operations, it appears that we
    must flush the render cache or else we risk render corruption. This is
    usually noticeable in rendering of single glyphs.
    
    This was originally fixed for bug 51422, but was reintroduced by
    commit 37eb7343be1aeeb90a860096756603a577df1a77

    If all the outputs are off, we try to resize the screen to 1x1, which is

    next time it is enabled.

    sna: Defer move-to-gpu until we need to transfer GPU damage to CPU
    
    When preparing a pixmap for CPU rendering, one of the last steps is to
    copy the outstanding GPU damage back to the CPU. Currently, we flush any
    outstanding pageflips (for TearFree) and in the process accidentally
    destroy the shadow buffer if there is no outstanding GPU damage. Rearrange
    the code to avoid tripping over that by only processing the move-to-gpu if
    we need to touch the GPU bo.

    into the pixmap (for Composite setups) which may have resulted in
    corruption. The path was also failing to consider the impact of reusing
    an active CPU bo when it could be discarding the unwanted damage and
    reallocating.

    on the gc is not always bit exact (e.g. alpha channel) with the pixel
    value. As a result, we would oft miss drawing anything when rendering
    into the scanout.

    sna: Avoid erroneous discarding operations for partial composites
    
    Composite operations were presumed to cover their entire width x height
    area. However, a few paths submit boxes that do not cover the clip
    region and so the optimisation made during prepare to discard completely
    overwritten data is incorrect (and leads to corruption - stale data is
    seen which the client expected to have been overdrawn). So along these
    more unusual paths, we must add a flag to prevent the overzealous
    discard. Notably, xfce4 triggers this as it uses a lot of unantialiased
    trapezoids in its theme drawing.

    Provide DRI2DriverVDPAU for future compatibility
    
    Since 2010, DRI2 supports multiple driver names. That was added to ease
    selection of appropriate driver by libvdpau. As for today, intel driver
    support only DRI2DriverDRI (== 0), but not DRI2DriverVDPAU (== 1).
    
    Although there is no any hardware-specific VDPAU driver for intel video
    adapters at the moment, it would be easier to use generic drivers like
    libvdpau-va-gl by creating symlink named libvdpau_i965.so.1. That way
    appropriate driver will be selected in run time automatically:
    libvdpau_i965.so.1 on i965 equipped machines, and libvdpau_nvidia.so.1
    on nvidia equipped ones.
    
    [ickle: Whilst I think this is a workaround for a brainfart in libvdpau
    that it defaults to libvdpau_nvidia.so rather than first to
    libdvpau_${DRI2DriverDRI} and then to a hardcoded libvdpau_backend.so,
    I have no better solution, and this does seem in accordance with the
    spec.]

    sna: Nullify pixmap->devPrivate.ptr after promoting CPU bo to GPU
    
    When we convert a CPU bo into a GPU bo, we need to remove any dangling
    shadow pointers we use for devPrivate.ptr. Whilst the bo remains alive
    these are incoherent, but if we ever replace the GPU bo (for example to
    change tiling for DRI2) then the dangling pointer becomes invalid and
    will explode on next use.

    run the event handler for the device. This can then cause us to evaluate
    pending completed vblank events, which may in turn then attempt to use

    sna/gen4+: Drop new assertion that we only finish a vbo after use in this batch
    
    A full vbo might not be discarded and so upon first use in the following
    batch we decided to finish the old vbo and allocate a new. This can
    happen before we even emit any relocations and so the assert is bogus.

    tiling fallbacks, resulted in hitting a path where the source offset was
    subsequently ignored. This leads to the operation reading from invalid
    memory (or hitting the assert warning about the same).

    sna: Rename the two variants of pwrite so very relative dangers are obvious
    
    Since we extend the write in the cache-aligned routine, it runs the risk
    of reading from beyond the end of the allocation. As such, callers
    should be carefully vetted to make sure that their allocations are
    already cache-aligned (typically page-aligned). To make it obvious that
    this complexity exists, rename the routine.

    sna: Use the unoptimized pwrite for general buffers
    
    When we call kgem_bo_write() we have less control over the allocation of
    the buffer, and do not ensure it meets the alignment criteria required
    for the cacheline optimisation. So use the simple pwrite routine to
    avoid reading beyond the end of the allocation.

    sna: Handle transient TearFree flip failures
    
    If we get a pageflip fail when trying to do a TearFree update, just
    fallback to a copy (before turning off the display for complete
    failure). The rare tearing copy should mar the user experience far less.

    It didn't consider the height of the glyph above the baseline, i.e. it

    glyph_extents() is sufficiently fast never to show up in profiles.
    (Until then QA should spot the ~10% regression.) An alternative would be
    to feed the drawable clip extents to the render engine and avoid manual
    clipping if the clip region covers the whole drawable.

    sna/glyphs: Fix computation of extents for long strings
    
    And make sure we consider such overflowing strings for correct clipping
    against Windows.
    
    To offset the cost of doing a full extents check (~10% on aa10text), we
    introduce an approximate extents query (~1% on aa10text). The disparity
    should be rare, and should be an overestimate to force redundant
    clipping.

    sna: Expand packed KMS structs for 64-bit alignment
    
    Pavel Roskin found that with a 32-bit build of the DDX with a 64-bit
    kernel that the call to GETCONNECTOR was overwriting the 4 bytes beyond
    the end of the drm_mode_get_connector structure. This would appear to be
    due to the surreptious padding inserted by the compiler so that the
    structure would be naturally aligned on a 64-bit system. To compenstate
    we need to insert padding between the adjacent 32-bit structures on the
    stack.
    
    As usual, be paranoid and make sure that all the adjacent KMS structs we
    use are padded out to an 64-bit boundary.

    When querying the current backlight value, be sure not to overwrite the
    last user set value by the call to RRChangeOutputProperty.
    RRChangeOutputProperty calls into set_backlight_property, tricking us
    into believing that the user has set a new backlight value. The result
    is that we end up believing that the user chooses a 0 backlight if she
    should happen to query the property whilst the output is disabled.

    sna: Resize an existing framebuffer if possible
    
    Sometimes we may have a compatible scanout cached, but of the wrong
    size. Instead of throwing away the memory and creating a new scanout
    from scratch, allow us to just resize the old scanout by destroying and
    recreating its associated framebuffer.

    sna/video: Discard old video buffers when the frame size changes
    
    Back in the good old days of the overlay, we only needed to care about
    having a frame buffer large enough to hold the data. This changed with
    the sprite interface which encodes the width x height into the
    framebuffer and so we need to be careful when handing back a cached
    buffer that it does indeed match the required dimensions.

    sna: Catch SIGBUS to prevent X death
    
    We know that when we access either a CPU or GTT mmap we are vulernable
    to receiving a SIGBUS. In fact, we can catch these and abort the
    operation preventing X and all of its clients from randomly dieing.
    
    This helps for instance if you try and use a 1GiB frontbuffer on a 2GiB
    machine...
    
    For complete protection, we also need to catch signals for all GTT maps,
    such as VBO and staging buffers. (TBD)

    sna/gen4: Remove long dead code for forced batch emission between CA passes
    
    Forcing the batch emission on virtually every glyph eats a lot of CPU
    time sending very short commands to the GPU, and is totally unnecessary.

    the includes were juggled around to avoid pulling in xorg-server.h
    outside of the driver. However, missing xorg-server.h leads to subtle
    bugs in the layout of structures, in this case breaking xf86Options.

    Oh my, bspec is missing a few details on how to perform a scanline wait
    on Haswell. But by using the extra steps required for Ivybridge, we can
    successfully send events from the scanout to the BCS ring. Sadly this
    again means that to use vsync on Haswell requires preventing the GPU
    from sleeping whilst it waits for the scanout to advance.

    sna/gen6+: Don't request extra caching for use-once upload buffers
    
    As we only use these buffers once, we should not benefit from requesting
    them to be moved into L3/LLC cache - over and above the default
    recommendations we make when creating the buffer. Indeed, this may even
    lead to artefacts if we fail to invalidate those other caches when
    reusing the buffers.

    intel-virtual-overlay: Reset damage across modesets
    
    Some versions of the Xserver lose Damage tracking across the modeset,
    causing a loss of damage notifications and repainting to cease on the
    virtual outputs. We can workaround this by reattaching the damage every
    time we receive notification that the local Screen configuration
    changes.

    tools: Add intel-virtual-output to extend the local desktop with remote outputs
    
    Based on the original implementation (hybrid-screenclone) by
    Tomáš Janoušek, and Bumblebee integration by Kevin Puetz.
    
    intel-virtual-output utilizes local VirtualHeads to present a contiguous
    desktop to the local display manager, but maps the drawing on those
    outputs to the remote display, and provides bidirectional RandR proxy so
    that you can resize the remote display and configure it within your
    desktop. The remote display should also send hotplug events back to the
    local desktop, for reconfiguration on the fly.
    
    Ideally the remote display is a discrete GPU on the same host so that we
    can use local Shared Memory transport and avoid sending data over the
    wire (though it will work in that setup). Ideally you would have userptr
    support to provide zero-copy rendering between the GPUs, or have dma-buf
    (in which case you would be using PRIME). For remote rendering, no
    compression is done so this fares worse than VNC.

    sna: Allow user specification of number of VirtualHeads
    
    Previously, we instantiated a fake output in case we had a machine with
    no output. (For certain server-class products.) The Bumblee project were
    also doing something very similar in order to fake an extended desktop
    on the Intel igfx and copy portions onto a discrete GPU. (The preferred
    method for doing this upstream is through the use of PRIME). As the code
    is very similar, we can support both use-cases simultaneously.
    
    This adds the option:
    
    Section "Device"
      Driver "intel"
      Option "VirtualHeads" "<count>"
    EndSection
    
    to allow the user to specify an additional set of fake outputs, which
    can then be controlled using xrandr.

    sna/video: Disable the existing sprite when switching CRTCs
    
    After starting a new video on another CRTC, disable the old one as we
    currently only track the single video port. However, showing a video
    split across multiple CRTCs would be a useful extension in the future.

    sna/gen7: Prefer the render ring for more operations
    
    As we get more well-endowed GPUs with ever more execution units, it
    becomes advantageous to do even basic copies through the render ring.
    However, the extra performance comes at a cost - higher power usage. To
    mitigate this, we apply a heuristic of only allowing a switch over to
    the render ring if the render ring is already active with an early
    request (in addition to the usual stall avoidance and general
    performance heuristics).

    the RENDER ring benefits from more cacheing over time (e.g. HSW:GT3e) it

    sna: Avoid leaking stolen framebuffer bo
    
    Framebuffers created from stolen bo were not being released and so the
    kernel would keep the fb and bo alive, causing the memory to be
    remain unreusable whilst X lived and us to leak all available stolen
    memory.

    sna: Rename the attribute macro __packed__ to avoid clang barfing
    
    Using __packed__ as shorthand for ___attribute__(__packed__) confuses
    clang as. (I guess to it expands (__packed__) which gcc skips.) As
    clang also uses packed in its builtins, we have to find a compromise,
    and so tightly_packed wins for being a more verbose description without
    the dangerous leading underscores.

    sna/dri: Disable TripleBuffering by default for compositors
    
    Ideally, the method of swapping is something that the applications have
    control over, along with how to synchronise to the vertical refresh.
    Whilst triple buffering is good to reduce jitter for games (at the cost of
    an extra frame of latency, usually considered a good tradeoff), it
    prevents the applications from accurately controlling the presentation
    of animations. One vocal critique is Owen Taylor, who demands accurate
    swap control for smooth animations in gnome-shell. For example,
    
    http://blog.fishsoup.net/2012/11/28/avoiding-jitter-in-composited-frame-display/
    
    In lieu of application control, just apply a quirk for the compositor.
    Everyone else will just have to wait for DRI3.

    On Iris, we may store the framebuffer in the eLLC/LLC and mark it as

    writes are cached and coherent with the display).

    sna/dri: Discard the strict checking for stale bo before performing a blit
    
    Instead of checking that the DRI2Buffers match up with the current
    DRI2Drawable, clip the area that is being copied to the minimum extents
    of the Drawable, source and destination buffers. This ensures that we
    never read nor write beyond the extents of the allocated or visible
    regions.

    Prompted by a suggestion by Haihao, clarify the intent behind checking
    the incoming maximum blit extents against the recorded sizes of the
    attached bo. Due to the asynchronous nature of DRI2 invalidation, it is
    possible for the DRI2 buffer to be stale and for its bo to be smaller
    than required for the client's blit.

    Atter a modeset or KMS takeover, we do a quick readback of the kernel
    state in order to verify that it matches our expectations. If we find
    that a foreign framebuffer is attached, or no mode if set on the output,
    we then turn off that connection and release any resources associated

    requests to turn off a connection.

    sna: Add a fast path for reading back from tiled X bo
    
    This is lower latency than the double copy incurred for first moving the
    bo to the CPU and then copying it back - but due to the less efficient
    tiled memcpy, it has lower throughput. So x11perf -shmget500 suffers
    (by about 30%) but real world applications improve by about 2x.

    sna/gen5: Force a write flush when changing blend modes
    
    Otherwise it appears that the hardware will readback from memory
    bypassing its render cache after a change of modes. There is probably a
    lot more subtly to it than this, but this appears to be a good first
    approximation.

    Since the call to the busy_ioctl is predicated on whether the bo needs
    to be flushed by us, therefore when forcing the call to the busy_ioctl
    to flush the GTT we need to mark it as requiring needs_flush.

    The DRI2 midlayer may, or may not, recreate the back buffer after a
    pixmap change. The result is that the back buffer may or may not be
    flagged as unsuitable for flipping, so be paranoid and double check.
    (This behaviour was first introduced in 1.9.0 and looks to be removed

    Adding more reserved PCI IDs for Haswell.
    
    As Chris mentioned there is a tendency for us to find out more
    PCI IDs only when users report. So let's add all new reserved Haswell IDs.
    I didn't have better names for this reserved ids and didn't want to use rsvd1
    and rsvd2 groups, so I decided to use "B" and "E" that stands for the last
    id digit.

    When publishing first HSW ids we weren't allowed to use "GT3" codname.
    But this is the correct codname and Mesa is using it already.
    So to avoid people getting confused why in Mesa it is called GT3 and here
    it is called GT2_PLUS let's fix this name in a standard and correct way.

    DRI2GetMSC: Do not send a bogus ust for when the drawable is not displayed
    
    According to the opengl glx_sync_control spec, the Unadjusted System Time
    (or UST) is a 64-bit monotonically increasing counter that is available
    throughout the system:
    http://www.opengl.org/registry/specs/OML/glx_sync_control.txt
    
    Therefore, sending 0, even in this corner case, is out of spec. However,
    we cannot just return FALSE here as that triggers a BadDrawable error to
    be sent, and as is often the case mishandled, to the client. This results
    in a certain compositor terminating, for example.
    
    As an alternative we can use the monotonic system timestamp which in
    theory should also be monotonic with the previous and subsequent vblank
    times.

    being clipped.

    sna: Haswell reintroduces MI_LOAD_SCAN_LINES
    
    Better late than never? Interestingly only available from the BLT ring,
    which makes accurate waiting for XVideo (which must use the render ring)
    impossible in the current form - we need to render to a temporary then
    do a vsynced blit in this case.

    sna/dri: Fix stale Pixmap detection
    
    NB the back buffer is not associated with the Drawable and so has no
    pixmap field set. Hence comparing the front->pixmap against the
    back->pixmap was always rejecting the blit. All we can check is that
    front->pixmap corresponds with the current Drawable and so reject stale
    configuration.

    uxa: don't crash when freeing an uninitialized screen
    
    When intel_scrn_create creates a screen, it sets scrn->driverPrivate to
    (void *)(match_data | 1).  Normally, this is read by I830PreInit and then
    replaced with a pointer to the intel_screen_private structure.  However, it's
    possible for the server to delete the screen before initializing it, which leads
    to a crash in I830FreeScreen when it tries to interpret the unaligned match_data
    pointer as a pointer to a intel_screen_private.
    
    Fix this by checking the low bit of the pointer and skipping the teardown code
    if it's set.

    As the wakeup handler is called more frequently, we want to avoid any of

    check to see if the GPU is idle and so we should immediately flush what
    we have currently queued.

    uxa/gen7: Don't use a message register to store vl
    
    Turns out the "new" assembler that uses mesa's opcode emission hits the
    path that automatically transforms MRF registers into GRF ones in the
    exa_wm_src_projective shader.
    
    The diff with the new assembler is:
    
    $ intel-gen4disasm -g7 -
    -   { 0x00600041, 0x208077be, 0x008d03c0, 0x008d0180 },
    +   { 0x00600041, 0x2e8077bd, 0x008d03c0, 0x008d0180 },
    mul(8)      m4<1>F          g30<8,8,1>F     g12<8,8,1>F     { align1 };
    mul(8)      g116<1>F        g30<8,8,1>F     g12<8,8,1>F     { align1 };
    
    Of course, message registers are no more in gen7, so the shader is
    trying to do something shaddy (ahem!).
    
    Instead of using m4, let's make exa_wm_src_projective use g68 for v (aka
    vl) which makes sense since:
    
    1/ vh is g69
    2/ exa_wm_src_affine uses g68 for vl already
    
    This commit changes the generated assembly, here's the decoded diff:

    Confirm that i915.ko has KMS enabled before binding to the device
    
    If the kernel has the module, but the KMS module option is not enabled,
    we cannot function. So after checking to see if the i915.ko is bound,
    then querying whether it provides any KMS resources. If it has no CRTCs
    attached, then we need to failover to the VESA/fbdev drivers. Note that
    this should have been detected by drmCheckModesettingSupported()

    I misinterpreted Sedat Dilek's advice on how to fix my confusing
    changelog, so drop the Xorg 7.7 confusion and just refer to the version
    of Xserver the driver is first compatible with.

    sna/gen4: Restore nonrectiinear spans workaround
    
    Instead of relying on the macro, the intention was simply to use the
    prefer_gpu hint. However, I dropped it whilst refactoring ideas from
    later generations. So restore both the debug control to force spans as
    well as the intended workaround.

    sna: Free the handle after pwrite buffer allocation failure
    
    Having just allocated the handle, we need to free it if we then fail to
    allocate memory for the buffer.

    sna: Flush our caches if we fail to mmap an object
    
    The likely cause for a mmap failure is that we hold too many objects
    open or have exhausted our address space. In both cases, we need to trim
    our caches before continuing.

    sna: Handle mapped buffer allocation failure for LLC
    
    The presumption was that if we had LLC we would have allocated the
    buffer by that point - however, it was remotely possible to have fallen
    through and so we need to handle those cases.

    When running autoreconf, it's possible to give flags to the underlying
    aclocal by declaring a ACLOCAL_AMFLAGS variable in the top level
    Makefile.am.
    
    Putting ${ACLOCAL_FLAGS} there allows the user to set an environment
    variable up before running autogen.sh and pull in the right directories
    to look for m4 macros, say an up-to-date version of the xorg-util macros.

    sna: Prevent falling back to swrast if source is on the GPU
    
    Currently if the dst is wholly contained within the CPU, then we try to
    continue to operate on the GPU. However, if we have FORCE_GPU set, it
    means that one of the sources for the operation resides on the GPU, and
    that would require a readback in order to perform the operation on the
    CPU. Hence, if we try to use a CPU bo and fail, convert back to using
    the GPU bo if forced.

    intel: Throttle harder
    
    Filling the rings is a very unpleasant user experience, so cap the
    number of batches we allow to be inflight at any one time.
    
    Interestingly, as also found with SNA, throttling can improve
    performance by reducing RSS. However, typically throughput is improved
    (at the expense of latency) by oversubscribing work to the GPU and a
    10-20% slowdown is commonplace for cairo-traces. Notably, x11perf is
    less affected and in particular application level benchmarks show no
    change.
    
    Note that this exposes another bug in libdrm-intel 2.4.40 on gen2/3.

    sna: Refine check for an unset context switch
    
    So it appears that we end up performing a context switch on an empty
    batch, but already has a mode. This is caught later, too late, by
    assertions. However, we can change the guards slightly to prevent those
    assertions without altering the code too greatly. And I can then think
    how to detect where we are setting a mode on the batch but doing no
    work - which is likely masking a bigger bug.

    dri2: don't schedule a flip prematurely at ScheduleSwap time
    
    If divisor is 0 but the current MSC is behind the target, we shouldn't
    schedule a flip (which will occur at the next vblank) or we'll end up
    displaying it early and returning the wrong timestamp.
    
    Preserve the optimization though by allowing us to schedule a flip if
    both the divisor is 0 and the current MSC is equal to or ahead of the
    target; this avoids a round trip through the kernel.

    sna: Only flush before adding fresh surfaces to the batch
    
    Previously, before every operation we would look to see if the GPU was
    idle and we were running under a DRI compositor. If the GPU was idle, we
    would flush the batch in the hope that we reduce the cost of the context
    switch and copy from the compositor (by completing the work earlier).
    However, we would complete the work far too earlier and as a result
    would need to flush the batch before every single operation resulting in
    extra overhead and reduced performance. For example, the gtkperf
    circles benchmark under gnome-shell/compiz would be 2x slower on
    Ivybridge.

    sna/dri: Prevent scheduling a swap on stale buffers
    
    If the screen has been reconfigured and the DRI client tries to swap the
    old buffers (having not processed the invalidate event and retrieved the
    current names), quietly drop the request. If we try to obey the request,
    we will end up attaching a back buffer that is the wrong size to the
    scanout...

    uxa: Disable bo reuse after binding to a scanout
    
    On gen6+, bo are expected to be LLC by default. However, as using the bo
    for the scanout causes it to be moved into the uncached domain, this
    assumption is then false and we should release the bo back to the system
    rather than spread the uncached buffers around. The most common
    allocator of scanouts is for pageflipping which are already non-reusable
    due to the DRI2 export, so there should actually be little impact.

    Fix possible_clones computation for shared encoders between outputs
    
    Libdrm's possible_clones is a mask of encoders. Xorg's possible_clones
    is a mask of outputs, so we just can't do the following:
    
      output->possible_clones = kencoder->possible_clones;
    
    This is a problem on Haswell because, at least with the current
    patches floating on the mailing list, there is more than one connector
    per encoder.
    
    This patch writes the code to properly translate libdrm's encoder mask
    into Xorg's output mask.

    sna: Use inplace X tiling for LLC uploads
    
    Based on a suggestion by Chad Versace (taken from a patch for mesa).
    
    This allows for a faster upload of pixel data through a ShmImage, or for
    complete replacement of a GPU bo.
    
    Using a modified version of x11perf to upload to a pixmap rather than
    scanout on an IVB i7-3720qm:
    
    Before:
    40000000 trep @   0.0007 msec (1410000.0/sec): ShmPutImage 10x10 square
     4000000 trep @   0.0110 msec (  90700.0/sec): ShmPutImage 100x100 square
      160000 trep @   0.1689 msec (   5920.0/sec): ShmPutImage 500x500 square
    
    After:
    40000000 trep @   0.0007 msec (1450000.0/sec): ShmPutImage 10x10 square
     6000000 trep @   0.0061 msec ( 164000.0/sec): ShmPutImage 100x100 square
      400000 trep @   0.1126 msec (   8880.0/sec): ShmPutImage 500x500 square
    
    However, the real takeaway from this is that the overheads for
    ShmPutImage are substantial, only hitting around 70% expected efficiency,
    and overshadowed by PutImage, which for reference is

    Skip adding unknown special modes
    
    In light of the discussion on how to add stereo modes it was revealed
    that we would happily add modes with unknown and unhandled strange
    flags. Adam Jackson mentioned that he has plans to fix that with some
    upcoming work, but as a first step we can simply eradicate them whilst
    pondering how to support the stereoscopic vision of the future.

    sna: Workaround issue with global glyph privates and shared ZaphodHeads
    
    Under ZaphodHeads we end up with multple screens accessing the common
    sna_glyph_key and so cause conflicting updates and erroneous references
    into the screen-local texture atlases.
    
    Two approaches can be tried here. Transition to a screen-specific
    private key introduced with xorg-1.13, or to move the glyph cache (and
    the rest of the gpu state tracker) down into the device private rather
    than screen private. This is neither of those, but a workaround to avoid
    reusing the incorrect entries from shared screens.

    sna: Drop master after discarding framebuffers
    
    As Imre Deak pointed out in the previous patch, drmModeRmFB only works
    when we hold the DRM master, therefore to prevent a leak of the
    framebuffer across server reset we need to defer dropping master until
    after we release our scanouts and modes.

    uxa: fix leakage of FB when closing the screen
    
    Calling drmModeRmFB is only allowed in DRM master mode. Since leaving
    the VT also drops master mode we need to remove the FB before calling
    I830LeaveVT.
    
    This is only a real leak in case of a server reset, otherwise the server
    process will exit anyway and the kernel will clean up the FB.

    sna: Force the stall if using a busy ShmPixmap bo with PutImage
    
    As we will stall in the near future to serialise access with the
    ShmPixmap, we may as well stall first and do a simple copy using the
    CPU in this highly unlikely scenario.

    This reverts commit 5a5212117e7a73ce3fffb87c60a505a849e38c36.
    
    The clean up is in effect too early, as this is during preparation and
    the actual work is already being correctly done at the end.

    Add Option "Backlight" to override the probed backlight control interface
    
    The automatic selection may not correspond with the correct backlight
    (such as in a multi-gpu, multi-panel device) or the user may simply
    prefer another control interface. This allows them to override the
    chosen interface using
    
      Option "Backlight" "my-backlight"
    
    to specify '/sys/class/backlight/my-backlight' as the interface to use
    instead.

    sna/gen6+: Do not call sna_blt_composite() after prepping the composite op
    
    As sna_blt_composite() will overwrite parts of the composite op as it
    checks whether or not it can execute that operation, it will lead to a
    crash as the normal render path finds the op corrupt. (The BLT
    conversion functions cater for the cases where we may wish to switch
    pipelines after choosing src/dst bo.)

    which made the presumption that we called sna_add_flush_pixmap() for

    dirty pixmaps, any native exported pixmap only marks the batch as
    requiring a flush. So in those cases we always need to submit the batch
    if it contains an exported DRI pixmap.

    sna: Check the composite extents against the clip
    
    When computing the composite extents (as opposed to the composite
    region) also check if the resultant box overlaps the destination clip
    region (we know it already fits into the extents). This helps in cases
    with small roi against clipped drawables, such as drawing text onto
    expose events.

    sna/gen7: Simplify the force-stall detection
    
    After reducing the number of conditions where we think we need to force
    the stall on the results, we can then simplify the code to detect
    that remaining case.

    sna/gen4+: Implement an opacity shader
    
    Avoid the cumbersome lookup through the alpha gradient texture and
    simply multiply the incoming opacity value. The next step will be to
    reduce the number of floats required per vertex.
    
    Now that we have removed the primary user of the alpha solid cache, it
    may be time to retire that as well.

    sna: Restore inplace upload for DRI compositors
    
    With a DRI compositor we have to flush the output after every request,
    which leads to major inefficiencies. This can be mitigated slightly if
    we know we will have to upload shortly, which we track using the pixmap
    flush flag.
    
    In particular PutImage is meant to upload inplace to an active DRI
    buffer, however this was accidentally dropped in

    sna: Prefer platform backlight devices over firmware
    
    This is in contrast to libbacklight but closer to our original code as
    we prefer a known custom backlight controller over the ACPI interfaces.
    As only the ACPI interfaces are marked as firmware, and the custom
    backlight controllers as platform, we therefore need to prefer platform
    backlight devices.

    sna: Simply reverse all the boxes if dx <= 0 and dy <= 0
    
    In this fairly common case, avoid both the double pass and use a simpler
    algorithm as we can simply reverse the order of the boxes.

    sna: Split CloseScreen into two phases
    
    In order to get the ordering correct we need to free the xf86_cursors
    before calling the miPointerCloseScreen. This requires us to insert a
    hook at the top of the CloseScreen chain. However we still require the
    final CloseScreen hook in order to do the fundamental clean up, hence
    split the CloseScreen callback into two phases.

    If we can acheive the same rasterisation results without the mask,
    rendering the glyphs-to-dst is so much faster that it outweighs the cost

    The penalty is then for code that correctly declared that it required

    sna: Check for overlapping glyphs within each list, then overlapping lists
    
    Spotted by Zhigang Gong is this optimisation to avoid the problem with
    multiple lines passed in a single request (using multiple lists). As the
    start of line will overlap with the previous line when we use the simple
    bbox comparison, we always declare those runs as overlapping and so we
    cannot substitute a glyph mask. However, we can reduce the problem to
    only checking for overlapping glyphs within a list and then checking for
    overlapping lists. Very, very clever.

    sna: Only consider large clears as candidates for GPU migration
    
    If we only operating on a small region of the pixmap and have require
    damage migration in the past, we are likely to require migration again
    at some point. So keep track of small damage areas.

    We consideer a singular FillRect to be a sequence point in the rendering
    commands, that is it is usually used to clear the background as the first
    operation in a drawing sequence. So it is useful to ask if we can move
    the sequence to the GPU at that point.

    With the introduction of the third pipe on IvyBridge it is possible to

    native resolutions. (It is conceivable to hit similar issues on earlier

    sna/gen7: prefer using RENDER copy
    
    Further testing and the balance of doubt swings in favour of using the
    3D pipeline for copies.
    
    For small copies the BLT unit is faster,
    2.14M/sec vs 1.71M/sec for comppixwin10
    
    And for large copies the RENDER pipeline is faster,
    13000/sec vs 8000/sec for comppixwin500
    
    I think the implication is that we are not efficiently utilising the EU
    for small primitives - i.e. something that we might be able to improve.

    sna/gen7: Emit a pipeline flush after every render operation
    
    For whatever reason, this produces a 30% improvement with the fish-demo
    (500 -> 660 fps on i7-3730qm at 1024x768). However, it does cause about
    a 5% regression in aa10text. We can appear to alleviate that by only
    doing the flush when the composite op != PictOpSrc.

    Encode the third pipe using the HIGH_CRTC shift for vblanks
    
    The original vblank interface only understood 2 pipes (primary and
    secondary) and so selecting the third pipe (introduced with IvyBridge)
    requires use of the HIGH_CRTC. Using the second pipe where we meant the
    third pipe could result in some spurious timings when waiting on the
    vblank.

    As pointed out by Soren Sandmann and Behdad Esfahbod, it is essential to

    is correctly performed when adding to an incompatible mask format.
    
    For example, loading alpha as the source results in the value 000a being
    added to the rgba glyph mask (for mixed subpixel rendering with
    grayscale glyphs), whereas the desired value is aaaa.

    Post Damage on the Screen Pixmap after a pageflip
    
    This issue was raised by Dave Airlie as he is trying to integrate
    multiple GPUs into the xserver, and a particular setup has a slave
    rendering device that copies the contents from the GPU over a
    DisplayLink USB adaptor. As such the slave device is listening for
    Damage on the Screen Pixmap and needs the update following pageflips.
    Since we already are posting damage for all the SwapBuffers paths other
    than pageflip, for consistency we should post damage along the pageflip
    path as well.

    used for when we feel like the following operation would be better on
    the CPU and just want to confirm that doing so will not stall.

    sna: Actually create Y-tiled source pixmaps
    
    An inconsistency highlighted by 7c51cabaecac revealed that we had a
    mismatch between the check in move_to_gpu() and how we created the
    pixmap. This mismatch resulted in us creating and uploading tiled
    pixmaps for single shot textures, and the increase aperture pressure was
    causing a regression in firefox-fishbowl on pnv, for example.

    sna: Suppress DBG prints along potential SIGIO paths
    
    As ErrorF/fprintf is not re-entrant due to its mutex we can not use DBG
    from code that could be called by a signal handler. X's SIGIO handler
    attempts to move the cursor from within the handler (eek!) and so we
    need to be careful not to take any locks, such in as the aforementioned
    fprintf, along the cursor paths.

    uxa: Remove dead-code for SourcePictures
    
    All SourcePictures are now converted into Drawables, which had been
    assumed by the driver backend. However, the code still existed to
    attempt to pass procedural pictures onwards and so set pSrcPix to NULL
    which was being flagged by the static analyser as a potential NULL
    dereference.

    It seems clear then that even with the extra synchronisation cost
    copying from the GTT is much preferable with the GPU than using the
    uncached reads by the CPU. Streaming write-combines from the CPU into
    the GTT seem about as efficient as we can manage, so continue to use the
    mapping unless busy.

    The return from __kgem_throttle_retire() is just a hint as to whether
    any forward progress was made. In the case of the error path, though it
    is a last ditch effort before aborting, so we do not really care whether
    or not it succeeds, we must try again.

    If the pixel exists only in the CPU damage, attempting to read it back

    sna/glyphs: use add(WHITE, glyph, mask) for channel expansion
    
    If the glyph format does not match the mask format we can not simply add
    the two together, but must first perform a channel expansion (or
    contraction) by multiplying the glyph against a WHITE source.
    
    Normally the glyph and the mask are equivalent formats and so we hit the
    fast path.

    Commit 8a9a585341e2 ("Only create a single instance of the intel_options
    array") moved the definition of intel_options into a separate .c file.
    Several of the defined options are #ifdef'd based on the configuration,
    but since config.h is never included, the macros being tested are never
    defined.  Therefore, none of the configuration-specific options will
    ever be available at runtime, even if they should be.
    
    Add an inclusion of config.h so that such configuration-specific options
    work again.

    sna: Improve handling of inplace IO for large transfers
    
    If the transfer is large enough to obliterate the caches, then it is
    preferrable to do it inplace rather than upload a proxy texture and
    queue a blit. This helps prevent an inconsistency where one layer
    believes the operation should be done inplace only for the IO layer to
    perform an indirect upload.
    
    Testing show no significant impact upon the cairo-traces, but it does
    prevent x11perf -shmput from exploding.

    As we may end up holding onto and releasing the Screen pixmap last, we
    may also be responsible for flushing the last reference to the scanout.

    sna: Remove the assertions that the cached upload buffers are active
    
    These were added to track down some corruption, but the assertions
    themselves are incorrect, just very rare. The upload buffer may
    genuinely be cached if we abort the render operation after uploading the
    source data, leaving the proxy not coupled to any request.

    sna: Discard proxy upload buffer if we choose to render to it
    
    Even if we try to avoid treating an upload buffer as a real GPU target,
    we may still choose to migrate the buffer to the GPU in order to keep
    other buffers on the GPU. In that case, we do want to create a real GPU
    bo.

    sna: Don't consider upload proxies as being on the GPU for render targets
    
    The upload proxy is a fake buffer that we do not want to render to as
    then the damage tracking become extremely confused and the buffer it
    self is not optimised for persistent rendering. We assert that we do not
    use it as a render target, and this patch adds the check so that we
    avoid treating the proxy as a valid target when choosing the render
    path.

    The shaders treat colours as an argb value, however the clear color is
    stored in the pixmap's native format (a8, r5g6b5, x8r8g8b8 etc). So
    before using the value of the clear color as a solid we need to convert
    it into the a8r8g8b8 format.

    sna: Minimise the risk of hotplug hangs by checking fb before vsync
    
    Everytime we issue a MI_WAIT_FOR_EVENT on a scan-line from userspace we
    run the risk of that pipe being disable before we submit a batch. As the
    pipe is then disabled or configured differently, we encounter an
    indefinite wait and trigger a GPU hang.
    
    To minimise the risk of a hotplug event being detected and submitting a
    vsynced batch prior to noticing the removal of the pipe, perform an
    explicit query of the current CRTC and delete the wait if we spot that
    our framebuffer is no longer attached. This is about as good as we can
    achieve without extra help from the kernel.

    Since the removal of the ability to create a backing pixmap after the

    should reconstruct the shadow mapping.

    sna: Check for flush at the start of every WriteToClient
    
    The goal is to simply avoid the flush before going to sleep when we have
    no pending events. That is we only want to flush when we know there will
    be at least on X_Reply sent to a Client. (Preferably, it would a Damage
    reply!) We can safe assume that every WriteToClient marks the beginning
    of a new reply added to the Client output queue and thus know that upon
    the next flush event we will emitting a Reply and so need to submit our
    batches.
    
    Second attempt to fix a438e4ac.

    sna: Encourage promotion of snooped CPU bo to real GPU bo
    
    This fixes the regression in performance of fishietank on gen2. As
    the texture atlas is too large to be tiled, one might presume that it
    has the same performance characteristics as the snooped linear CPU
    buffer. It does not. Therefore if we attempt to reuse a vmap bo, promote
    it to a full GPU bo. This hopefully gains the benefit of avoiding the
    copy for single shot sources, but still gives us the benefit of avoiding
    the clflushes.
    
    On the plus side, it does prove that gen2 handles snoopable memory from
    both the blitter and the sampler!

    Dust off the kernel patches and update to reflect the changes made to

    However, due to the forced synchronisation required for strict client

    already busy (i.e. sync afterwards rather than before in the hope that
    we can squash a few operations into one). Being able to block the reply
    to the client until the request is actually complete and so avoid the
    sync remains a dream.

    All X.Org modules must be able to be configured with autoconf 2.60.
    In addition, version 2.63 has GPL licensing issues which prevents
    some vendor to release software based on it.
    
    The AM_SILENT_RULES are already handled by XORG_DEFAULT_OPTIONS.
    
    All X.Org modules must be able to be configured with libtool 1.5.
    
    AM_MAINTAINER_MODE default value is "enabled" already.
    
    We use the same autogen script for all x.org modules.
    There are proposals for changes which should be reviewed and eventually
    applied to all modules together.
    
    The lt*.m4 patterns are already included in the root .gitignore file.
    This can be proposed as a change to all modules, but it invloves
    changing the topvel .gitignore, the m4/.gitignore, the ACLOCAL_AMFLAGS
    and the AC_CONFIG_MACRO_DIR together.
    
    For more information on project wide configuration guidelines,

    The heuristic of using the mapping only before the first use in an

    uxa/glamor/dri: Enable the pageflip support on glamor.
    
    To support easy buffer exchange at glamor layer, glamor
    added a new API glamor_egl_exchange_buffers() to exchange
    two pixmaps' EGL image and fbos and textures without
    recreating any of them. But this simple method's requirement
    is that there are two pixmaps. A exceptional case is:
    If we are using triple buffer when do page flipping, we
    will have an extra back_buffer which doesn't have a pixmap
    attached to it. Then each time we set that buffer to a
    pixmap, we will have to call the create_egl_textured_pixmap
    to create the corresponding EGL image and fbo and texture
    for it. This is not efficient.
    
    To fix this issue, this commit introduces a new back_pixmap
    to intel structure to hold the back buffer and corresponding
    glamor resources. Then we will just need to do the light
    weight buffer exchanging at both DDX and glamor layer.
    
    As the new back pixmap is similar to the screen pixmap
    and need to be handled carefully when close screen. As the
    glamor data structure is a per screen data, and will be
    released at its close screen method. The glamor's close
    screen method must cleanup the screen pixmap and back
    pixmap's glamor resources. screen pixmap is easy to get,
    but there is no good way to store the back pixmap.
    
    So the glamor add a new API glamor_egl_create_textured_screen_ext
    function to pass the back pixmap's pointer to glamor layer.
    
    This commit make us depend on glamor commit: 4e58c4f.
    And we increased the required glamor version from 0.3.0 to 0.3.1

    sna/gen6: Prefer the render ring for copies
    
    Slower for fills, but on the current stack faster for copies, both large
    and small. Hopefully, when we write some good shaders for SNB, we will
    not only improve performance for copies but also make fills faster on
    the render ring than the blt?
    
    As the BLT copy routine is GPU bound for copywinpix10, and the RENDER
    copy routine is CPU bound and faster, I believe that we have reached the
    potential of the BLT ring and not yet saturated the GPU using the render
    copy.
    
    Note that we still do not casually switch rings, so the actual routine
    chosen will still be selected by the preceeding operations, so is
    unlikely to have any effect in practice during, for example, cairo-traces.

    Upon reading, we encounter a serialisation point and so can retire all

    was still busy.

    sna/gen2+: Force upload rather than perform source transformations on the CPU
    
    If both the source and destination is on the CPU, then the thinking was
    it would be quicker to operate on those on the CPU rather than copy both
    to the GPU and then perform the operation. This turns out to be a false
    assumption if transformation is involved -- something to be reconsidered
    if pixman should ever be improved.

    sna: Limit max CPU bo size to prevent aperture thrashing on upload
    
    Copying between two objects that consume more than the available GATT
    space is a painful experience due to the forced use of an intermediatory
    and eviction on every batch. The tiled upload paths are in comparison
    remarkably efficient, so favour their use when handling extremely large
    buffers.
    
    This reverses the previous idea in that we now prefer large GPU bo
    rather than large CPU bo, as the render pipeline is far more flexible
    for handling those than the blitter is for handling the CPU bo (at least
    for gen4+).

    The previous version calls glamor_egl_close_screen and
    glamor_egl_free_screen manually which is not align with
    standard process. Now glamor change the way to follow
    standard method:
    
    glamor layer and glamor egl layer both have their internal
    CloseScreens. The correct sequence is after the I830CloseScreen
    is registered, then register glamor_egl_close_screen and
    the last one is glamor_close_screen. So we move out the
    intel_glamor_init from the intel_uxa_init to I830ScreenInit
    and just after the registration of I830CloseScreen.
    
    As the glamor interfaces changed, we need to check the
    glamor version when load the glamor egl module to make
    sure we are loading the right glamor module. If
    failed, it will switch back to UXA path.

    sna: Allow the creation of render targets larger than the maximum bo cache
    
    Given that we now handle uploads to and from bo that are larger than the
    aperture and that usage of such large bo is rare and so unlikely to
    benefit from caching, allow them to be created as render targets and
    destroy as soon as they become inactive.
    
    In principle, this finally enables GPU acceleration of ocitysmap on gen4+,
    but due to the large cost of creating and destroying large bo it is
    disabled on systems that require clflushing. It is, however, a
    pre-requisite for exploiting the enhanced capabilities of IvyBridge.

    sna: Decrease tiling step size in case we need to enlarge the box later
    
    We can juggle rendering into large bo on gen4 by redirecting the
    rendering through a proxy that is tile aligned, and so the render target
    may be slightly larger than the tiling step size. As that is then larger
    than the maximum 3D pipeline, the trick fails and we need to resort to a
    temporary render target with copies in and out. In this case, check that
    the tile is aligned to the most pessimistic tiling width and reduce the
    step size to accomodate the enlargement.

    two such images...
    
    The real complication comes in uploading (and downloading) from such

    automatic detiling via either the BLT or the RENDER ring. We could do

    We need to adjust the clip to include the border pixels when migrating
    damage from the backing pixmap. This also requires relaxing the
    constraint that a read must be within the drawable.

    sna: Round up buffer allocations when downsampling
    
    The pathological case being nx1 or 1xm resulting in an illegal allocation
    request of 0 bytes.
    
    One such example is
      wolframalpha.com: x = (200 + x) / 100
    which generates an approximately 8500x1 image and so needs downscaling
    to fit in the render pipeline on all but IvyBridge. Bring on Ivy!

    In order for us to produce stable downsampled images across multiple
    frames, we need to sample the same pairs of pixels every time. This
    requires us to align the origin of the sample region to an even pixel.

    and the total number of cachelines used. Base the decision on whether
    to try and amalgamate the upload with others on the number of bytes
    copied rather than the overall extents.

    be a useful optimisation along that path (tracking upload of partial
    images), so add the necessary booking that watches for when the union
    of cpu and gpu damage is no longer the complete set of all pixels
    written, that is if we either migrate from one pixmap to the other, the
    undamaged region goes untracked. We also take advantage of whenever we
    damage the whole pixel to restore knowledge that our tracking of all
    pixels written is complete.

    uxa/glamor: Create glamor pixmap by default.
    
    When creating native glamor pixmaps we will get much better performance
    than using the textured-drm pixmap, this commit is to make that the
    default behaviour when configured to use glamor. Another advantage
    of this commit is that  we reduce the risk of encountering the
    "incompatible region exists for this name" and the associated
    render corruption. And since we now never intentionally allocate
    a reusable pixmap we could just make all (intel_glamor) allocations
    non-reusable without incurring too great an overhead.
    
    A side effect is that those glamor pixmaps do not have a
    valid BO attached to them and thus it fails to get a DRI drawable. This
    commit also fixes that problem by adjusting the fixup_shadow mechanism
    to recreate a textured-drm pixmap from the native glamor pixmap. I tested
    this with mutter, and it works fine.
    
    The performance gain to apply this patch is about 10% to 20% with
    different workload.

    sna/gen6: Allow greater use of BLT
    
    Typically we will be bound to the RENDER ring as once engaged we try not
    to switch. However, with semaphores enabled we may switch more freely
    and there it is advantageous to use as much of the faster BLT as is
    feasible.
    
    The most contentious point here is the choice of whether to use BLT for
    copies by default. microbenchmarks (compwinwin) benefit from the
    coallescing performed in the render batch, but the more complex traces
    seem to prefer utilizing the blitter. The debate will continue...

    sna: Be more lenient wrt switching rings if the kernel supports semaphores
    
    If the kernel uses GPU semaphores for its coherency mechanism between
    rings rather than CPU waits, allow the ring to be chosen on the basis
    of the subsequent operation following a submission of batch. (However,
    since batches are likely to be submitted in the middle of a draw, then
    the likelihood is for ddx to remain on one ring until forced to switch
    for an operation or idle, which is the same situation as before and so
    the difference is miniscule.)

    Initially, the batch->mode was only set upon an actual mode switch,
    batch submission would not reset the mode. However, to facilitate fast
    ring switching with semaphores, reseting the mode upon batch submission
    is desired which means that if we submit the batch in the middle of an
    operation we must redeclare its mode before continuing.

    In the common case, we expect a very small number of vertices which will
    fit into the batch along with the commands. However, in full flow we
    overflow the on-stack buffer and likely several continuation buffers.
    Streaming those straight into the GTT seems like a good idea, with the

    buffers and if we had kernel support.)

    sna: Experiment with GTT mmapped upload buffers
    
    In a few places, we can stream the source into the GTT and so upload in
    place through the WC mapping. Notably, in many other places we want to
    rasterise on a partial in cacheable memory. So we need to notify the
    backend of the intended usage for the buffer and when we think it is
    appropriate we can allocate a GTT mapped pointer for zero-copy upload.
    
    The biggest improvement tends to be in the PutComposite style of
    microbenchmark, yet throughput for trapezoid masks seems to suffer (e.g.
    swfdec-giant-steps on i3 and gen2 in general). As expected, the culprit
    of the regression is the aperture pressure causing eviction stalls, which
    the pwrite paths sidesteps by doing a cached copy when there is no GTT
    space. This could be alleviated with an is-mappable ioctl predicting when
    use of the buffer would block and so falling back in those cases to
    pwrite. However, I suspect that this will improve dispatch latency in
    the common idle case for which I have no good metric.

    sna/trapezoids: Don't risk stalling for inplace SRC trapezoids
    
    Optimistically we would replace the GPU damage with the new set of
    trapezoids. However, if any partial damage remains then the next
    operation which is often to composite another layer of trapezoids (for
    complex clipmasks) using IN will then stall.
    
    This fixes a regression in firefox-fishbowl (and lesser regressions
    throughout the cairo-traces).

    sna/damage: Fix reduction to copy the boxes correctly
    
    We need to be carefully to copy the boxes in a strict lifo order so as
    to avoid overwritting the last boxes when reusing the array allocations.

    sna: Mark tiny CPU pixmaps as completely dirty
    
    Avoid the overhead of tracking damage on small pixmaps when using CPU
    rasterisation; the extra cost of sending the whole pixmap compared to
    the damage is negligble should it ever be required on the GPU.

    As rasterisation will be performed upon the CPU we need to avoid the

    clear that CPU damage and enable migration before a number of key steps

    One issue with the heuristic is that it is based on total pixmap size

    sna: Upload to large pixmaps inplace
    
    When the pixmap is large, larger than L2 cache size, we are unlikely to
    benefit from first copying the data to a shadow buffer -- as that shadow
    buffer itself will mostly reside in main memory. In such circumstances
    we may as perform the write to the GTT mapping of the GPU bo. As such,
    it is a fragile heuristic that may require further tuning.
    
    Avoiding that extra copy gives a 30% boost to putimage500/shmput500 at
    ~10% cost to putimage10/shmput10 on Atom (945gm/PineView), without any
    noticeable impact upon cairo.

    sna: Map the upload buffer using an LLC bo
    
    In order to avoid having to perform a copy of the cacheable buffer into
    GPU space, we can map a bo as cacheable and write directly to its
    contents. This is only a win on systems that can avoid the clflush, and
    also we have to go to greater measures to avoid unnecessary
    serialisation upon that CPU bo. Sadly, we do not yet go to enough length
    to avoid negatively impacting ShmPutImage, but that does not appear to
    be a artefact of stalling upon a CPU buffer.
    
    Note, LLC is a SandyBridge feature enabled by default in kernel 3.1 and
    later. In time, we should be able to expose similar support for
    snoopable buffers for other generations.

    uxa/glamor: Enable the rest of the glamor rendering routines
    
    This commit hooks up all the remaining rendering routines to call into
    glamor; the takeover is nearly complete! When tested with the latest
    glamor master branch, it passes rendercheck.
    
    One thing need to be pointed out is the picture's handling.
    Pictures support many different color formats, but glamor's
    texture only support a few color formats. And the most common
    scenario is that we create a pixmap with a color depth and
    then attach it to a picture which has a specific color format
    with the same color depth. But there is no way to change a
    texture's internal format after the texture was allocated.
    If you do that, the OpenGL will allocate a new texture. And
    then the glamor side and UXA side will be inconsitent. So
    for all the picture related operations, we can't fallback to
    UXA path directly, even it is rather a straight forward
    operation. So for the get_image, Addtraps.., we have to add
    wrappers function for them to jump into glamor firstly.

    sna: Implement a VMA cache
    
    A VMA cache appears unavoidable thanks to compiz and an excrutiatingly
    slow GTT pagefault, though it does look like it will be ineffectual
    during everyday usage. Compiz (and presumably other compositing
    managers) appears to be undoing all the pagefault minimisation as
    demonstrated on gen5 with large XPutImage. It also appears the CPU to
    memory bandwidth ratio plays a crucial role in determining whether
    going straight to GTT or through the CPU cache is a win - so no trivial
    heuristic.

    ~ drmModeConnectoSetProperty() enables/disables the backlight driver.
    Some backlight drivers such as intel_backlight set the backlight to 0
    when disabled and to max when enabled.
    ~ intel_output_dpms_backlight() saves the backlight value when turning
    DPMS off and restores it when turning DPMS on.
    
    Here's the current order of operations:
    
    xset dpms force off (backlight is nonzero)
       drmModeConnectoSetProperty(DPMSModeOff)
          kernel: disable backlight, backlight=0
       intel_output_dpms_backlight(DPMSModeOff)
          save backlight value (0) <-- it has been set to 0 by kernel
          set backlight to 0
    
    xset dpms force on
       drmModeConnectoSetProperty(DPMSModeOn)
          kernel: enable backlight, backlight=max
       intel_output_dpms_backlight(DPMSModeOn)
          set backlight to saved value (0)
    
    The correct way to do this would be to reverse the operations during
    xset dpms force off:
       intel_output_dpms_backlight(DPMSModeOff)
          save backlight value (nonzero)
          set backlight to 0
       drmModeConnectoSetProperty(DPMSModeOff)
          kernel: enable backlight, backlight=0
    
    This restores the saved nonzero backlight value during the force on.

    sna: Downgrade Y-tiling if we must use the BLT
    
    There are many operations, usually the core drawing acceleration, where
    the BLT is much more preferable than using the CPU. However, the BLT is
    limited to only using X-tiling, so if we encounter a Y-tiled pixmap
    target we need to recreate it as X-tiling before proceeding. Hopefully,
    the pixmap is then kept around and rendered multiple times to amoritize
    the cost of the copy.

    sna: Use Y-tiling for source pixmaps
    
    Y-tiling is slightly faster with RENDER operations, so attempt to
    allocate source-only pixmaps using this tiling mode. Actually using
    Y-tiling is a delicate balance because it then prevents the use of the
    BLT. For instance, enabling Y-tiling by default gives a 30% performance
    improvement on the fish-demo (compositing benchmark) at 2560x1440 on
    Ironlake but regresses tiger-demo by 2x (spans benchmark).
    
    So experiment with this compromise and allow for changing the default
    tiling.

    uxa: Make the glamor/uxa transition more verbose
    
    And so hopefully make it clearer. In the process we restore the flushing
    behaviour for UXA back to before the glamor intervention.

    sna/gen4: Use the special composite rect emission for fill_one()
    
    In order to workaround a bug in the shaders on gen4, we need to flush
    the pipeline after every rectangle. The recently introduced fill-one
    mechanism for gen4, missed this vital step triggering a random hang with
    an otherwise sane batchbuffer (the missing flush is hard to spot!).
    
    Fixes regression from 86f99379ee5 (sna/gen4: Add fill-one).

    1. Flush UXA batch buffer before call into glamor.
    2. Flush GL operations after return from a glamor function.
    3. The point we need to flush UXA batch buffer, we also
       need to flush GL operations, for example, in
       intel_flush_callback and couple of places in intel_display.c.

    sna: Handle incremental uploads from PutImage
    
    PutImage rarely uploads the entire image inside a single request,
    instead breaking up into scanline segments to fit within the protocol
    limits. A few optimisations are based on detecting when we can discard
    the GPU bo for an all-dirty CPU pixmap, which are useful in this case so
    check for an entirely dirty pixmap following an incremental PutImage.

    sna: Store the sna pointer on the pixmap for cheap lookups
    
    A large part of the function preamble overhead is the multi-indirection
    lookup for retrieving the sna pointer. We can eliminate most of these by
    storing a pointer on the Pixmap as well, which we often need to lookup
    anyway.

    sna/gen3: Fix false reduction of ComponentAlpha with white source
    
    The principle behind the opertator reduction of WHITE * maskca is valid,
    except that we failed to account for the src/mask transposition when
    emitting the vertices - garbage ensued.
    
    Given that we agressively reduce the shader required for WHITE * maskca,
    it does not seem worthwhile to special case the primitive emitter as
    well.

    We need to process the union of the PolyLine command if lineWidth!=0 so
    we cannot generally feed lineWidth==1 into our special case handler.
    Proving the lines do not intersect is as difficult as finding the
    intersections and thereby finding the union of the path - so there is no
    advantage in adding a check whether a wide line could be special cased.

    The goal is to remove a spurious wakeup when we have no work outstanding

    sna: Submit the batch on the next blockhander if operation overflows
    
    If an operation overflows from one batch into another, we submit the
    complete batch and begin a new. That new batch will not be submitted
    unless it is filled or on the next delayed flush update. This can cause
    a flicker as a large operation is broken up, such as performing a
    CopyArea through a Clipmask. So if we submit a full batch during a flush
    interval, immediately flush any partial batch at the next blockhandler.

    uxa: Remove caching of surface binding location
    
    If the pixmap were to be used multiple times within a batch with
    mulitple formats, the cache would only return the initial location with
    the incorrect format and so cause rendering glitches. For instance, GTK+
    uses the same pixmap as an xrgb source and as an argb mask in order to
    premultiply and composite in a single pass. Rather than introduce an
    overly complication caching (handle, format) mechanism, kiss and remove
    the invalid implementation.

    Applications may use the same pixmap with multiple formats within the
    same operation. For instance, you can premultiply and composite a normal
    pixmap in this manner.  However, as we reused the sampler binding
    locations of the source (without an alpha channel) for the mask, we
    failed to read and multiply by the alpha channel causing it to remain
    black instead of transparent.

    This reverts commit 15266e1b9500f6b348661c60d1982bde911f2d0e.
    
    KDE relies upon the ability to render into a sampler and then render
    upon itself. Not the first sign of madness...
    
    Will have to find another way of winning back the compwinwin
    performance.

    sna/composite: Fix incorrect operator reduction for RenderFillRectangles
    
    As exemplified by KDE (using Kate) on gen3, it would attempt to render a
    large set of boxes using OVER and a transparent colour. As gen3 copied
    across some of the BLT assumptions, it was incorrectly reducing that to
    a CLEAR and thus rendering incorrectly.

    sna: Actually apply the composite offset for the self-copy
    
    I translated the region to copy by the composite pixmap offset, only
    failed to use the translated region for the actual copy command (using
    instead the original boxes). Fix that mistake by avoiding the temporary
    region entirely and applying the translation inplace.
    
    We also have to be careful in the case of copying between two composited
    windows that have different offsets into the same screen pixmap.

    This is to workaround a ping-pong issue involving small icons. The

    anyway until we implement stippling...

    snb: implement PIPE_CONTROL workaround
    
    Sandybdrige requires an elaborate dance to flush caches without
    hanging the gpu. See public docs Vol2Part1 1.7.4.1 PIPE_CONTROL
    or the corrensponding code in mesa/kernel.
    
    This (together with the corresponding patch for the kernel) seems to
    fix the hangs in cairo-perf-traces I'm seeing on my snb machine.
    
    v2: Incorporate review from Chris Wilson. For paranoia keep all three
    PIPE_CONTROL cmds in the same batchbuffer to avoid upsetting the gpu.

    sna: Move the source to the GPU if it is reused
    
    We attempt to skip upload a source pixmap to the GPU in the event it is
    used only once (for example during image upload by firefox). However, if
    we continue to use the CPU source pixmap then it obviously was worth
    uploading to the GPU. So if we use the CPU pixmap a second time, do the
    upload and then blit.

    Using spans has a tremendous effect (~100x) on x11perf, some good but

    appears to be CPU bound and so it seems like there should be plenty of
    scope for recovering the lost performance.
    
    However, for the time being, just go back to the old fallbacks.

    sna/glyph: Avoid useless attempt at GPU glyph rendering to a1 destinations
    
    The actual bug is a little involved as we don't damage the temporary
    glyph mask correctly presuming that we only hit GPU paths. However,
    should we fail to prepare the composite operation that paints the mask
    on to the destination, things fail horribly.
    
    One particular example is that wine like to create its own temporary a1
    buffer for the glyphs (which we render to via another temporary mask...)
    which triggers the delayed fallback and then sw compositing with a random
    buffer.

    sna/dri: Play with marking bo reusable
    
    Since we have no recycling of wc pages in the kernel, we try hard to
    recycle buffers in userspace to avoid GTT thrashing. This requires
    co-operation between DRI clients and X, which is sadly lacking and so we
    need to discard any buffer given out to a client after it is finished.
    We cheat slightly for page-flips and access to the scanout.
    
    A further compromise.

    configure: Introduce --with-builderstring
    
    Julien Cristau disliked my broadcasting of the git tree used to build
    his distribution package as it bore little relevance to his users. As it
    is only useful for people installing their own drivers (as a means of
    sanity checking that they are running the right driver), we introduce
    the --with-builderstring idiom borrowed from the xserver. This allows
    the builder to override the use of `git describe` and either leave it
    blank or to fill it with something useful for their own purposes.

    We cannot assume that the edge lies completely within the target, so we
    must make sure that the initial prev_x is truly less than any possible
    value whilst sorting intersections.

    sna: Use the shadow buffer for PutImage
    
    This is optimising for the x11perf putimage benchmark, but nevertheless,
    uploading the PutImage directly into the uncached scanout is between
    2-20x slower than making a temporary copy in the shaodw buffer and
    doing a deferred update. Most of the overhead is in the kernel, and
    should be addressed there (rather than worked around) and a portion is
    due to the overdraw in the benchmark (which is not likely to be
    realistic, but then again neither should PutImage be!).
    
    The argument for uploading inplace when possible is that given that the
    buffer already exists on the GPU implies that is likely to be used again
    in future by the GPU and so we will be uploading it at some point.
    Deferring that upload incurs an extra copy. The putimage benchmark does
    not actually use the pixel data and so that extra cost is not being
    measured.

    sna/gen6: Prefer the BLT ring, except for copies on behalf of DRI
    
    As demonstrated by the all-important trap300, using the BLT is 2x faster
    than the RENDER ring for the simple case of solid fills. (Though note
    that performing the relocations costs 3x as much CPU for 2x GPU
    performance.) One case that may regress from this change is copywinpix
    which should benefit from the batching in the RENDER commands, and might
    warrant revisiting in the future (with realistic and synthetic
    benchmarks in hand!)
    
    However, due to the forced stall when switching rings, we still want to
    perform RENDER copies on behalf of DRI clients and before page-flips.
    
    Checking against cairo-perf-trace indicated no major impact -- I had
    worried that setting the BLT flag for some clears might have had a
    knock-on effect causing too many operations that could be pipelined on
    the RENDER ring to be sent to the BLT ring instead.

    dri: Do not tile stencil buffer
    
    Until now, the stencil buffer was allocated as a Y tiled buffer, because
    in several locations the PRM states that it is. However, it is actually
    W tiled. From the PRM, 2011 Sandy Bridge, Volume 1, Part 2, Section
    4.5.2.1 W-Major Format:
        W-Major Tile Format is used for separate stencil.
    
    The GTT is incapable of W fencing, so we allocate the stencil buffer with
    I915_TILING_NONE and decode the tile's layout in software.
    
    This commit mutually depends on the mesa commit:
        intel: Fix stencil buffer to be W tiled

    dri: Enable triple-bufferred pageflips
    
    By popular demand.
    
    Triple-buffering trade-offs output latency versus jitter. By having a
    pre-rendered frame ready to swap in following a pageflip, we avoid the
    scenario where the latency between receiving the flip complete signal
    from the kernel, waking up the vsynced application, it render the new
    frame and then for the server to process the swap request is greater
    than the frame interval, causing us to miss the vblank. The result is
    that application can become frame-locked to 30fps. Instead, we report to
    the application that the first frame swap is immediately completed,
    supply a new back buffer (or else the rendering would be blocked on
    waiting for the front-buffer to be swapped away from the scanout) and
    let them proceed to render the second frame. The second frame is added
    to the swap queue, and the client throttled to vrefresh. (If the client
    missed the vblank, the swap queue is empty and the client is immediately
    woken again, whilst the pageflip is pending.)
    
    Note, for practical reasons this only applies to page-flipping, for
    example, calls to glXSwapBuffer() on fullscreen applications.

    dri: Prevent abuse of the Resource database
    
    The Resource database is only designed to store a single value for a
    particular type associated with an XID. Due to the asynchronous nature
    of the vblank/flip requests, we would often associate multiple frame
    events with a particular drawable/client. Upon freeing the resource, we
    would not necessarily decouple the right value, leaving a stale pointer
    behind. Later when the client disappeared, we would write through that
    stale pointer upsetting valgrind and causing memory corruption. MDK.
    
    Instead, we need to implement an extra layer for tracking multiple
    frames within a single Resource.

    This is quite trivial to hit given the 2k limits on gen2/gen3. We
    compromise on image quality by pre-downscaling the source by a fixed
    factor to make it fit into the pipeline in preference to performing the
    entire operation on the CPU.

    sna/dri: Accurately track front and pending front for async flips
    
    By not tracking the front buffer correctly, i.e. performing the exchange
    on every swap, GL_FRONT was no longer pointing at the updated buffer and
    neither was the root pixmap. So both X and GL would read the wrong
    buffer was the flip was pending.
    
    The other issue was that we would feed the old front buffer back to the
    application as a future back buffer (due to buffer caching) and so the
    kernel would duly insert a WAIT_EVENT for the pending flip to complete
    before allowing rendering to affect it.

    sna: Place the pixmap on the DRI dirty list after damaging the shadow copy
    
    In order that we remember to flush the contents back to the GPU
    before we wake up the DRI clients, we need to add those dirty
    pixmaps to the flushing list. I caught the obvious place, the
    central move-to-cpu, but I missed a couple of paths were we
    optimise the copy onto the shadow.

    dri: Add support for DRI2BufferStencil and DRI2BufferHiz
    
    And bump configure.ac to require dri2proto >= 2.6, because
    DRI2BufferStencil and DRI2BufferHiz were introduced in that version.
    
    When a client requests DRI2BufferHiz or DRI2BufferStencil,
    I830DRI2CreateBuffer() now returns a Y-tiled buffer. The stencil buffer is
    handled as a special case due its quirky pitch requirements.

    dri: Do not create DRI2 buffers for unrecognized DRI2 buffer tokens
    
    Before this commit, if a client were to request an unrecognized DRI2
    buffer, such as DRI2BufferStencil, then I830DRI2CreateBuffer() allocated
    and returned an X-tiled buffer by accident. The problem was that
    unrecognized tokens were caught by the default case of a switch statement.
    
    Now, when given unrecognized DRI2 tokens, I830DRI2CreateBuffers() returns
    null.
    
    This shouldn't break older Mesa versions, because they never query (via
    DRI2GetBuffersWithFormat) for the drawable's DRI2BufferStencil.

    sna: Add zaphod support
    
    Zaphod support is a rudimentary method for creating an Xserver with
    multiple screens from a single device. The Device is instantiated, with
    a duplication of its resources, as many as required up to a maximum of
    the number of its outputs, and each instance is attached to a Screen
    and added to the ServerLayout. A Device can be bound to a selection of
    outputs using a comma separated list of RandR names.
    
    Note: in general, this is not the preferred solution! And will be
    superseded by per-crtc-pixmaps in RandR-1.4.
    
    For example, the following xorg.conf fragment creates an XServer with
    two screens, one attached to the LVDS panel on the laptop, and the other
    to any external output:
    
    Section "Device"
    	Identifier "Intel0"
    	Driver     "intel"
    	BusID	   "PCI:0:2:0"
    	Option     "ZaphodHeads" "LVDS1"
    	Screen     0
    EndSection
    
    Section "Device"
    	Identifier "Intel1"
    	Driver     "intel"
    	BusID	   "PCI:0:2:0"
    	Option     "ZaphodHeads" "DVI1,VGA1"
    	Screen     1
    EndSection
    
    Section "Screen"
    	Identifier "Screen0"
    	Device     "Intel0"
    EndSection
    
    Section "Screen"
    	Identifier "Screen1"
    	Device     "Intel1"

    uxa: Simplify BLT solid acceleration for spans filling by only clipping once.
    
    We were clipping each span against the bounds of the clip, throwing
    out the span early if it was all clipped, and then walked the clip box
    clipping against each of the cliprects.  We would expect spans to
    typically be clipped against one box, and not thrown out, so we were
    not saving any work there.  For multiple cliprects, we were adding
    work.  Only for many spans clipped entirely out of a complicated clip
    region would it have saved work, and it clearly didn't save bugs as
    evidenced by the many fix attempts here.

    sna: Introduce a new acceleration model.
    
    The premise is that switching between rings (i.e. the BLT and
    RENDER rings) on SandyBridge imposes a large latency overhead whilst
    rendering. The cause is that in order to switch rings, we need to split
    the batch earlier than is desired and to add serialisation between the
    rings. Both of which incur large overhead.
    
    By switching to using a pure 3D blit engine (ok, not so pure as the BLT
    engine still has uses for the core drawing model which can not be easily
    represented without a combinatorial explosion of shaders) we can take
    advantage of additional efficiencies, such as relative relocations, that
    have been incorporated into recent hardware advances. However, even
    older hardware performs better from avoiding the implicit context
    switches and from the batching efficiency of the 3D pipeline...
    
    But this is X, and PolyGlyphBlt still exists and remains in use. So for
    the operations that are not worth accelerating in hardware, we introduce a
    shadow buffer mechanism through out and reintroduce pixmap migration.
    Doing this efficiently is the cornerstone of ensuring that we do exploit
    the increased potential of recent hardware for running old applications and
    environments (i.e. so that the latest and greatest chip is actually faster
    than gen2!)
    
    For the curious, sna is SandyBridge's New Acceleration. If you are
    running older chipsets and welcome the performance increase offered by
    this patch, then you may choose to call it Snazzy instead.

    [Note the performance regression for ocitysmap comes from that we now
    attempt to support rendering to and (more importantly) from large
    surfaces. By enabling such operations is the only way to one day be
    faster than purely using the CPU, in the meantime we suffer regression
    due to the increased migration and aperture thrashing. The other couple
    of regressions will be eliminated with improved span and shader support,
    now that the framework for such is in place.]
    
    The performance increase for Cairo completely overlooks the other
    critical aspects of the architecture:
    
    World of Padman:
    gen3 (800x600):   57.5 ->  96.2
    gen4 (800x600):   47.8 ->  74.6
    gen6 (1366x768): 100.4 -> 140.3 [F15]
                     144.3 -> 146.4 [drm-intel-next]
    
    x11perf (gen6);
    aa10text:     3.47 -> 14.3 Mglyphs/s [unthrottled!]
    copywinwin10: 1.66 -> 1.99 Mops/s
    copywinpix10: 2.28 -> 2.98 Mops/s
    
    And we do not have a good measure for how much improvement the reworking
    of the fallback paths give, except that xterm is now over 4x faster...
    
    PS: This depends upon the Xorg patchset "Remove the cacheing of the last
    scratch PixmapRec" for correct invalidations of scratch Pixmaps (used by
    the dix to implement SHM operations, used by chromium and gtk+ pixbufs.

    Ensure that the partial batch is flushed upon the blockhandler
    
    Currently, we require that a batch containing a dirty bo be submitted
    before we mark the device as requiring a flush. So if we never submit a
    batch between block handlers, we can end up sleeping without ever
    flushing either the partial batch or the rendering to the scanout.

    This changes the code to only use pageflipping if the Option
    "SwapbuffersWait" is set to "TRUE" (default).
    
    Jesse's comment was that this should be superseded by actually
    supporting asynchronous page flips. As we are missing kernel and dix level
    support for that, in the meantime honour the config option.

    Take advantage of the kernel flush for dirty bo in the busy ioctl
    
    Rather than just creating and submitting a batch that simply contains a
    flush in order to periodically ensure that rendering reaches the
    scanout, we can simply ask the kernel whether the scanout is busy. The
    kernel will then submit a flush on our behalf if it is dirty, which
    takes advantage of the kernel's dirty state tracking.

    dri: Disable page-flip between a tiled buffer and a linear scanout
    
    Keith Packard pointed out a loophole that could cause the DDX to end up
    with a tiled scanout even if the user required a linear framebuffer;
    that is by using page-flipping we could replace the scanout pixmap with
    another of our choosing, and not necessarily tiled.
    
    Close that loophole by only allowing an exchange of buffers between
    identical tiling modes. For the common case, this is fine since they
    will indeed be allocated with the same tiling. For the linear
    framebuffer case with mesa using a tiled pixmap, we force it to blit
    onto the scanout instead.

    uxa: Fallback if the temporary is too large
    
    If the render operation requires a temporary source Picture and the
    operation is large, larger than the maximum permitted bo, then we will
    fail to allocate the bo. In this case, we need to fallback and perform
    the operation on the CPU rather than dereference a NULL bo.

    i965: Remove broken maximum base addresses from video
    
    WRONG.
    
    The hardware was never limited to 0x1000000 and the kernel can quite
    rightly place objects above that limit. Specifying such had no relation
    to reality, so why did we do it? TWICE!

    The region is used to paint onto the backing pixmap (and thus
    translated) prior to being passed to the damage layer (wrt to the

    Fix textured video when destination is larger than screen
    
    In our application, the screen is never rotated from the point of view
    of the driver; instead, the compositor applies a suitable rotation as
    it composites the display. This works fine on 945, but on 965, videos
    are limited in height to the actual height of the screen.
    
    Change various bits of code so that we use the width and height of the
    destination pixmap instead of the width and height of the virtual
    screen. This works correctly both for XVideo to offscreen storage
    (CompositeRedirect) and for XVideo to the screen (no compositor).

    Suggest where to find xorg-macros in case it's missing
    
    [Modified version of U. Artie Eoff's commit to remove the duplicated
    string. The paraphrased commit message is repeated below for clarity.]
    
    xorg-macros is often package under an unusual name, so provide some
    clues as to what name to try on the user's distribution. Installing
    build-deps would be just too easy...
    
    Also include a check for the existence of the XORG_DRIVER_CHECK_EXT
    macro, otherwise configure might continue in spite of the missing macro
    and cause obtuse syntax errors.

    Check consistency of pageflip completion vblank count.
    
    Implements a consistency check on returned vblank
    count values of pageflip completion. Impossible
    values are detected, a x-warning is logged and
    returned (msc,ust) values are marked invalid,
    so clients could perform error handling. Such
    a warning would indicate bugs in the pageflip

Date:   Thu Dec 9 03:12:35 2010 +0100

    Fix reporting of pageflip completion events on multi-head.
    
    When a drawable is page-flipped on multiple crtc's (fullscreen
    drawable on mirror-mode or multi-head x-screen), only one pageflip
    event is finally delivered, after the last participating crtc signals
    flip completion, this to avoid visual corruption.
    
    Old code returned vblank count and timestamps of flip completion
    of this last crtc, instead of the values of the "master crtc", the
    one that was used for initially scheduling/triggering the pagflip
    via vblank events. (master = I830DRI2DrawablePipe(drawable))
    
    This patch makes sure that the pageflip completion values of the
    "master" crtc are returned, otherwise client applications will
    get confused by the random (msc, ust) values returned by whichever
    crtc was the last to complete its flip. Without this, the returned
    values change randomly and jump forward and backward in time and
    count.

    Wait for any pending rendering before switching modes.
    
    A perennial problem we have is the accursed WAIT_FOR_EVENT hangs, which
    occur when we switch the framebuffer before the WAIT_FOR_EVENT completes
    and upsets the GPU.
    
    We have tried more subtle approaches to detected these and fix them up in
    the kernel, to no avail. What we need to do is to delay the framebuffer
    flip until the WAIT completes, which is quite tricky in the kernel
    without new ioctls and round-trips. Instead, apply the big hammer from
    userspace and synchronise all rendering before changing the framebuffer.
    I expect this not to cause noticeable latency on switching modes (far
    less than the actual modeswitch) and should stop these hangs once and
    for all.

    Remove the intermittent GEM_THROTTLE call.
    
    This is a holdover from early GEM work when we weren't syncing on the
    DRI client side.  It would keep clients from getting too far ahead and
    killing their interactivity, by bringing everyone to a halt when
    anyone was too far ahead.
    
    Now, GL clients throttle themselves to avoid the problem, and it turns
    out that in the case that they don't (long rendering to buffers with
    no swap), this actually reduces X Server interactivity: instead of
    lagging of X rendering behind input, you get no response for seconds
    at a time, then a burst of rendering, then nothing again.
    
    Reported by ajax.  Tested with moving a window while running
    cairo-perf-trace on the GL backend (improvement) and X backend (no
    significant change in responsiveness).

    This reverts commit 48b4e224297fa807be0e2bc7a67bf7e94579e8de.
    
    The better fix is to manually mark the pixmap when acceleration is and
    is not permitted. Whilst the devPrivate.ptr are invalid upon creation,
    it is not worth carring code that serves no purpose.

    Clear pixmap->devPrivate.ptr [regression from 7c7294e]
    
    ModifyPixmapHeader(pixdata = NULL) does not clear the
    pixmap->devPrivate.ptr, instead the NULL value is interpreted as meaning
    to keep the current value. (This is similar to the interpretation of the
    other invalid values like depth=-1 which also mean not to change the
    current property). However pixadata=NULL is indeed a valid value, and in
    7c7294e, devPrivate.ptr == NULL was used to differentiate a bo pixmap
    from a system pixmap. Except that we never did clear the ptr as
    intended, and so X would immediately crash.

    shadow+dri2: Allow dri2 to be independently enabled with shadow
    
    To enable DRI we create GEM buffers for the client to render into with
    hardware acceleration. In order to maintain coherency between any 2D
    render operations with the independent 3D clients (this includes the
    reading of 2D rasterisation by the direct rendering client, e.g.
    compiz using texture_from_pixmap) we need to replace the shadow pixmap
    with the GTT mapping. Therefore 2D rendering to a DRI buffer will be to
    uncached memory and thus penalised -- but the direct rendering clients
    will have full hardware acceleration.

    Disable dri2 after forcing fallbacks
    
    If we force fallbacks, then we will only create pixmaps in system
    memory, preventing DRI2 from passing valid bo names to the clients. In
    this case, they will just fallback to swrast. If we disable DRI2 after
    forcing fallbacks (e.g. regenerating after a GPU hang or explicitly
    disabled with the shadow buffer) then it is simpler just to disable the
    extension and allow mesa to use pure swrast.

    Enable a shadow buffer and disable GPU acceleration.
    
    An attempt to workaround the incoherency in gen2 chipsets, we avoid
    using dynamic reallocation as much as possible.
    
    The first step is to disable allocation of pixmaps using GEM and simply
    create them in system memory without a backing buffer object. This
    forces all rendering to use S/W fallbacks.
    
    The second step is to allocate a shadow front buffer and assign that to
    the Screen pixmap. This ensure that the front buffer remains in the GTT
    and pinned for scanout. The shadow buffer will be rendered to in the
    normal fashion via the Screen pixmap, and be marked dirty. In the block
    handler, the dirty shadow buffer is then blitted (using the GPU) over
    the front buffer. This should completely avoid having to move pages
    around in the GTT and avoid incurring the wrath of those early chipsets.
    Secondly, performance should be reasonable as we avoid the ping-pong
    caused by the small aperture and weak GPU forcing software fallbacks.

    This commit is not ready, as first the driver needs to handle all

    interface.  Fortunately, by moving that discovery into the kernel - where
    it just means finding which ACPI device is attached to the video and has a
    backlight interface - the userspace code should become much more sane,
    and work even with multi-gpu, multi-lid systems.
    
    But that is for tomorrow.

    There are a few cases where the server will flush client output buffers
    but our block handler only catches the most common (before going into select).
    If the server flushes client buffers before we submit our batch buffer,
    the client may receive a damage event for rendering that hasn't happened yet.
    
    Instead, we can hook into the flush callback chain, which the server will
    invoke just before flushing output.  This lets us submit batch buffers
    before sending out events, preserving ordering.

    video: kernel overlay needs triple buffering
    
    The kernel overlay code does asynchronous overlay flips. So keep
    onto two old buffers, for otherwise the rendering of the next
    frame might overwrite the contents of the currently still displaying
    one. With ~25fps videos and ~50 Hz screens that's rather unlikely,
    still, fix it.

    simplify Makefile as per-target compilation flags are not needed
    
    Per-target compilation flags (libIntelXvMC_la_CFLAGS) are required
    when multiple targets which require different compiler flags,
    are build in the same makefile.
    
    Automake issues a command with -c and -o flags which not all compilers
    support. The object fles are prefixed with libIntelXvMC_la.
    The macro AM_PROG_CC_C_O must then be used to provide this feature
    on compilers that do not have it. If not, a warning is issued at make time.
    
    This macros checks for compiler support and if missing, uses a "compile"
    script it generates in the package root directory.
    
    Currently the driver uses per-target flags but the macro is missing.
    Rather than adding the macro, this patch stops using per-target flags
    by using the AM_CFLAGS variable for all targets in the makefile, as
    there is only one.

    video: Reuse the old buffers.
    
    After passing the new buffer to the kernel, the old buffer is unpinned
    and becomes available for re-use. So keep hold of the old buffer and
    swap after a PutImage. This greatly reduces the amount of CPU time
    consumed by the kernel on behalf of the video overlay -- by only
    allocating two buffers for an entire sequence, we avoid clflushing and
    page allocation on every frame.

    Limit maximum tiled stride to 8k and untiled to 32k.
    
    Tiling on gen 2/3 hardware is only supported for pitches up to 8192
    bytes, so above this limit the surface will be untiled and we will no
    longer have to comply with the power-of-two pitch alignment. So
    disabling tiling for these too wide surface should ~halve the memory
    requirement for the full surface.
    
    Also the absolute limit for the 2D blitter is 32,768 bytes. The
    documentation says "up to 32,768 bytes" and my PineView box was
    malfunction with a surface stride of 32,768 so set the limit to be
    32,767.

    i965: Mark the render target as dirty within composite_setup()
    
    The key difference between i965 and earlier, is that the surfaces passed
    to the samplers through an indirect table and so the batch and render
    target was not being marked dirty by the relocation (since the
    relocation only happens within prepare_composite() which may have been
    in another batch.) Simply call intel_pixmap_mark_dirty() when binding
    the sampler table into the batch to ensure that the dirty is tracked
    appropriately.

    uxa: Enable SHM pixmaps
    
    Now with streaming uploads and downloads for composite operations in
    place, shared memory pixmaps are no longer that dire performance wise.
    With careful use these can in fact be the most efficient means of
    transfer between a wholly software renderer in the client and a backing
    store. For instance, Chromium renders internally to an ARGB32 image
    buffer and uses a shared pixmap to composite dirty regions into the
    backing store. Thereby using the GPU to either perform the blit or the
    format conversion. Enabling shared pixmaps, reduces our CPU overhead
    whilst scrolling by a factor of 5 or so.
    
    And this is achieved simply by deleting obsolete code!

    i915: Force the emission of BUF_INFO on every composite_setup
    
    We should be able to eliminate these as the drawable remains unchanged.
    However, the implicit flush of BUF_INFO fixes the rendering in KDE.
    Alternatively, we need an MI_FLUSH | INHIBIT_RENDER_CACHE_FLUSH between
    composites. (Note that it is not stale cache data causing the rendering
    corruption and that a pipelined flush is not sufficient either.) Also,
    having tried varies points at which to flush, the only place where the
    flush is effective seems to be between composite operations - that is a
    flush after 2D is not sufficient.

    i965: Sanity check ComponentAlpha status in prepare_composite
    
    Fixes:
    
      Bug 28446 - Garbled Font with Mathematica 7
      https://bugs.freedesktop.org/show_bug.cgi?id=28446
    
    Rewriting the glyphs to render to the destination directly and removing
    the more expensive multiple invocations of CompositePicture per picture
    was a great performance boost -- except that it needs special handling
    in the backend in order to not fallback. Having done so for i915, I
    neglected to ensure the sanity checking in i965_prepare_composite() was
    sufficient. As it turns out, it was not and so we misrendered CA-glyphs
    when rendering directly to the destination. This causes us to fallback
    properly, but is a performance regression as we no longer try the 2-pass
    magic helper before resorting to s/w. At the moment, I'd rather live
    with the temporary regression and fix i965 to do the same magic as i915,
    as it critical to fixing the severe performance issues currently
    crippling i965, as I believe that this regression only affects the
    minority of applications (incorrect, as it turns out, as the glyphs are
    overlapping) rendering directly to the destination.

    When I made libdrm stop overallocating so much memory for the purpose
    of bo caching, things started scribbling on the bottom of my

    mistake of size = tiled_pitch * height instead of size = tiled_pitch *
    tile_aligned_height.

    Disable acceleration if we detect a hardware error.
    
    This is wildly optimistic, but it should work in a surprising number of
    error situations and some output in those cases will be hopefully be
    better than none...
    
    If we submit a batchbuffer and the kernel reports the GPU is hung (which
    will be caused by an earlier execbuffer, and so the kernel should have
    had enough time to determine whether or not it could reset the GPU) then
    disable any further attempt to accelerate gfx and force fallbacks to map
    the buffers and use the CPU. We cannot normally map any more buffers if
    the GPU is hung, so only those already mapped prior to the hang can be
    written to, or those allocated in system memory. However, we can expect
    that the framebuffer is already mapped, and so have a reasonable
    expectation to continue to see the display update.

    dri: Only flip if the front and back pixmaps match.
    
    An unredirected window (thanks Michel for the reminder) is backed by the
    Screen pixmap, and so uses a reference of that as its front buffer. The
    back buffer is a pixmap appropriately sized for the drawable. When the
    application requests to swap its buffers, obviously we cannot simply
    exchange the front and back buffer as they do not match, but need to copy
    the appropriate region from the back to the front.

    Revert "dri: Use size from backing pixmap when creating buffers."
    
    This reverts commit 44d45d3fa56f121ce89ffe5b28beb48be01a95df.
    
    Michel Dänzer pointed out the flaw in using the pixmap size instead of
    the drawable size:
    
      Using the backing pixmap dimensions for this is not desirable. In
      particular, it means that the DRI2 buffers of non-redirected windows
      always have the same size as the screen. But even for redirected windows
      it wastes some graphics memory with a re-parenting window manager, that
      is if it doesn't break in various ways due to the top left corner of the
      DRI2 buffers no longer corresponding to the top left corner of the window.

    dri: Use size from backing pixmap when creating buffers.
    
    This avoid using the garbage values stored in the Screen drawable,
    instead of the true values which are only maintained in its backing
    pixmap. The consequence of using the wrong size was to hand a 1x1
    pixmap to metacity/mutter and have it believe it was a full screen
    drawable; GPU hangs ensued if using page flipping.

    uxa: Skip the redundant miComputeCompositeRects() when adding to the mask
    
    As we are in full control of the destination (the temporary glyph mask)
    and the source (the glyph cache) we know that there are no clip regions
    on either and so can skip computing the composite rectangles. (We trust
    the device clipping to prevent compositing outside the target.)

    uxa: Use temporary dest when target is too large for compositor
    
    If the destination cannot fit into the 3D pipeline when we need to
    composite, we fallback to doing the operation on the CPU. This is very
    slow, and quite easy to trigger on i915 by plugging in an external
    display.
    
    An alternative is to extract the extents of the operation from the
    destination using the blitter which can usually handle much larger
    operations. This gives us a temporary target that can fit into the 3D
    pipeline and thus be accelerated, before copying back into the larger
    real destination.
    
    For x11perf this boosts glyph rendering on PineView, from 38kglyphs/s to
    480kglyphs/s. Just a little shy of the native performance of 601kglyphs/s

    uxa: Composite glyphs directly onto dst when possible.
    
    Without using a mask and compositing directly onto the destination,
    takes us from 580 kglyphs/s to 850 kglyphs/s on i945 [x11perf -aa10text].
    
    However, the extra intersection check almost entirely cancels out the
    speed up and we discover that the glyphs in x11perf are always
    overlapping. Nothing is ever easy.

      Bug 28135 - [855GM] Slowdown/High CPU-Usage after Git-Commit

    The simple answer is that I had assumed that 0 was a reserved value.
    However, without the bbp encoded into the format 0 was used for a8r8g8b8
    and r5g6b5, which are very common formats!
    
    The other possibility for the slowdown is that gtkperf is using of the
    now verboten xrgb formats -- but would in fact be valid if the source
    covers the clip and we could fixup the alpha value in the fixed function
    combine.

    uxa: Force an alpha channel when rendering source fallbacks
    
    As the source may not cover the extents, we need to represent those
    areas as transparent in the fallback picture, ergo we need an alpha
    channel. We could be smarter and force a format conversion when
    necessary, and we could let the backend choose the most appropriate
    format.

    i830: Remove xrgb conversion to argb, no longer required.
    
    All textures are now properly declared so that the alpha swizzling
    occurs in the sampler or not at all. The downside is that for quite a
    few composite operations we have to fallback to software on older
    hardware. There is scope for more performing the alpha expansion in
    shaders or combiners when we know the picture covers the clip - which is
    almost all of the time for normal operations especially those
    constructed by Cairo.

    We need to prevent overcommitting the aperture, and in particular if we

    and rendering will fail. Trying to allocate multiple large buffers in

    eviction of useful buffers. So from the outset simply do not allocate a

      uxa: Extract sub-region from in-memory buffers.
    
    The issue is that as we extract the region prior to checking whether the
    composite can in fact be accelerated, we perform expensive surplus
    operations. This is particularly noticeable for ComponentAlpha text,
    such as rgb10text. The solution here is to rearrange the
    check_composite() prior to acquiring the sources, and only extracting
    the subregion if the render path can not actually handle the texture.

    The residual lossage seems to be from the extra function call and

    If the buffer is too large or not suitable for a GPU operation, we
    currently fallback and perform the composite on the CPU. An alternative
    is too extract the small region out of the source (as usually the
    sample extents are much smaller than the actual surface size) and try
    the composite with the new surface.
    
    The effect is particularly noticeable on pathological websites that use
    very large background images. For example, http://www.woodtv.com/ uses a
    1299x15000 pattern that is obscured by another opaque pattern.

    i830: Allocate bo's for glyphs larger than 32x32.
    
    As we only use the glyph cache for small glyphs, those large than 32x32
    will first be copied to a bo and used as a mask in a composite
    operation. We can avoid the allocation and upload per use by allocating
    a bo for the over-sized glyph from the start. As the glyph is large
    anyway, the excess memory allocation is less significant.
    
    Using normal font sizes, firefox shows no change - as expected. However,
    using the 36 font size traces, we see around a 10% improvement on g45.

    uxa: Try using put_image when copying from a memory buffer.
    
    Often, for example in the fallback for ShmPutImage, we will attempt to
    use uxa_copy_area() copying to a normal pixmap from a memory buffer.
    This triggers a fallback, and maps the destination pixmap back into the
    GTT. The accelerated put_image path will attempt to stream a blit to the
    destination pixmap if it is currently active, avoiding the stall.

    terms of bytes and the actual width of the surface.
    i830_pad_drawable_width() appears to be operating aligning *pixels* to a
    64 pixel boundary and has never used the chars-per-pixel causing
    considerable confusion in its callers. Remove the parameter and ensure
    that the callers are expecting a value in pixels returned, multiplying
    by cpp where necessary to get the pitch.

    Pauli pointed out that we take a ref on the front buffer when exchanging
    but forget to release it.  The ref is necessary since the set functions
    will drop refs as necessary, but once we set the front buffer to point
    at the back pixmap, we ned to release our private ref again, or we'll

    uxa: Default to using TILING_X for pixmaps.
    
    On memory constrained hardware, tiling is vital for good performance as
    it minimizes cache misses.  The downside is that for older hardware
    (which often suffers from the lack of bandwidth) requires the use of
    fences for many operations, which are in short supply and so may cause
    shorter batchbuffers. However our batch buffers are typically short and
    so this is unlikely to be a concern and not affect the performance wins.
    
    A quick bit of testing suggests the effect is inconclusive on
    firefox/i945:
                      linear            tiled
      xcb             205.470           206.219
      xcb-render-0.0  404.704           388.413
      xlib            166.410           170.805
    
    A secondary effect of the patch is to workaround a G31 specific hang
    when attempting to use linear 2048x2048 surfaces. Bonus!

    Fill alpha on xrgb images.
    
    Do not try to fixup the alpha in the ff/shaders as this has the
    side-effect of overriding the alpha value of the border color, causing
    images to be padded with black rather than transparent. This can

    i915 XvMC: fixup colors
    
    My cleanup accidently created a inconsistency in the YUV plane ordering.
    I think we can safely assume that I'm colorblind ;)
    
    As Carl Worth rightly pointed out, this change deserves a more elaborate
    explanation:
    
    For Xv planar formats, the three planes are stored consecutively in
    memory, ordered Y U V. Now for some totally odd reason (= none at all),
    i915 xvmc stored it in Y V U order. Right after the release of 2.10, with
    commit "Xv: consolidate xmvc passthrough handling" I've inadvertently
    broken xvmc support (which started this whole odyssey into xvmc). When
    fixing stuff up, I neglected this special plane ordering and simply
    assumed it to be the same as Xv and dropped that special case for i915 in
    src/i830_video.c. This patch completes the change to standard YUV plane
    ordering by making the corresponding change in src/xvmc/i915_xvmc.c.

    A couple more niggles: make sure we return a target_msc that at least
    matches the current count; this is a little more friendly to clients
    that missed an event.  Also check for >= when calculating the remainder
    so we'll catch the *next* vblank event when the calculation is
    satisfied, rather than the current one as might happen at times.

    DRI2: handle target_msc, divisor and remainder properly in DRI2ScheduleSwap
    
    The current code in I830DRI2ScheduleSwap() only schedules the correct
    vblank events for the case divisor == 0, i.e., the simple
    glXSwapBuffers() case.
    
    In a glXSwapBuffersMscOML() request, divisor can be > 0, which would go
    wrong.
    
    This modified code should handle target_msc, divisor, remainder and the
    different cases defined in the OML_sync_control extension correctly for
    the divisor > 0 case.
    
    It also tries to make sure that the effective framecount of swap
    satisfies all constraints, taking the 1 frame delay in pageflipping mode
    and possible delays in blitting/exchange mode due to
    DRM_VBLANK_NEXTONMISS into account.
    
    The swap_interval logic in the X-Servers DRI2SwapBuffers() call expects
    the returned swap_target from the DDX to be reasonably accurate,
    otherwise implementation of swap_interval for the glXSwapBuffers() as
    defined in the SGI_swap_interval extension may become unreliable.
    
    For non-pageflipped mode, the returned swap_target is always correct due
    to the adjustments done by drmWaitVBlank(), as DRM_VBLANK_NEXTONMISS is
    set.
    
    In pageflipped mode, DRM_VBLANK_NEXTONMISS can't be used without severe
    impact on performance, so the code in I830DRI2ScheduleSwap() must make
    manual adjustments to the returned vbl.reply.sequence number.
    
    This patch adds the needed adjustments.

    DRI2: handle offscreen drawables better at swap time
    
    If a drawable isn't visible due to DPMS or redirection, we'll just blit
    it rather than schedule a swap event.  However, we didn't reset the
    target_msc, so the swap target we receive from the server could get out
    of sync with the vblank count of the drawable's display.  So at DPMS on
    time, the swap target would be the last good vblank count plus some
    large number (since the swaps won't have been throttled).
    
    Solve this by zeroing out the swap target like we should when we fall
    back to a blit.  Also make the kernel error cases more friendly by
    making them fall back to blits too.

    i915 XvMC: switch ssb to drm_intel_bo
    
    This also starts to kill the last remnants of the support for
    physical addresses for the indirect state buffers. With gem this
    would need kernel support (in the form of a new reloc type in
    execbuf2).
    
    This does not change the ABI between ddx and client libIntelXvMC.
    I've decided to do this in one swoop when all the buffer rework is
    done.

    Seems to be a remnant from i810 XvMC support. last_flip is always 0,
    so serves no real purpose anymore. Kill it and the associated code.
    
    With last_flip gone, last_render also lost its purpose. Kill it, too.

    i915 XvMC: switch one_time_state_emit to batchbuffer macros
    
    This is in preparation for real relocatable drm_bo's instead
    of memory at a fixed address. By switching to the batchbuffer
    macros (like i965 xvmc) we can use the nice OUT_RELOC macro.
    
    Also align the code more with coding-style elsewhere, i.e. bitops
    instead of bitfield structures. The bitfield structures are
    quite a mess to work with the batchbuffer macros, so they were
    getting in the way, anyway.

    DRI2: handle full height blits without tearing in CopyRegion
    
    On 965 and up, if we detect a full height blit, we should just wait for
    vblank, rather than try to do a scanline wait for the whole display.
    
    On pre-965, doing a scanline wait followed by a blit works, but in the
    full height case we need to give the blitter time to start up, so we
    wait until the bottom line of the blit minus 2 padding scanlines to
    accommodate.
    
    Fixes FDO bug #22475.

    Extract pixel value for all formats to avoid hitting fallbacks.
    
    On failing to extract the pixel value for an alpha-only solid we
    actually triggered a fallback. Since this path is commonly hitting
    whilst fading in images, for example cairo_paint_with_alpha(), the
    fallback was detected during the Moblin boot sequence where it was
    adding a second to the overall boot time.

    Revert "uxa-glyphs: Enable TILING_X on glyph caches."
    
    This reverts commit 3f11bbec420080151406c203af292e55177e77d1.
    
    For unknown reasons, enabling tiling for the glyph cache is causing
    glyph corruption both across suspend and resume and VT switching, on a
    wide range of chipsets (reports include both i8xx and gm45)
    
    This strongly suggests that we are handling tiling, or updates to tiled
    buffers, incorrectly across i915_gem_idle(). However, until we can find
    the root cause, we want to fix this regression before the next stable
    release, so simply revert this patch. :(

    uxa: Cache solid fills.
    
    Maintain a small cache of pixmaps to hold SolidFill pictures. Currently
    we create a pixmap the size of the damaged region and fill that using
    pixman before downloading it to the GPU and compositing. Needless to say
    this is extremely expensive compared to simply emitting the solid
    colour. To mitigate this cost, we maintain a small cache of 1x1R
    pictures which is recognised by the driver as being a solid, but at the
    very least is maintained as a GPU ready pixmap.
    
    This gives a good boost to cairo-xcb (which uses solid fills) on a gm45:
    
    Before:
      gnome-terminal-vim: 41.9s
    After:
      gnome-terminal-vim: 31.7s
    
    Compare with using a cache of 1x1R pixmaps in cairo-xcb:

    batch: Ensure we send a MI_FLUSH in the block handler for TFP
    
    This should restore the previous level of synchronisation between
    textures and pixmaps, but *does not* guarantee that a texture will be
    flushed before use. tfp should be fixed so that the ddx can submit the
    batch if required to flush the pixmap.
    
    A side-effect of this patch is to rename intel_batch_flush() to
    intel_batch_submit() to reduce the confusion of executing a batch buffer
    with that of emitting a MI_FLUSH.
    
    Should fix the remaining rendering corruption involving tfp [inc compiz]:

    uxa: Review uxa_prepare_access() to remove potential nesting
    
    Around a call to uxa_put_image() it is possible to mix both accelerated
    and fallback paths, with the fallback code making the presumed
    optimisation of only trying to call uxa_prepare_access() once. This
    fails if the accelerated path also uses prepare/finish access on the
    same drawable and then later fallback to the fallback path. This can
    happen currently if an error is reported whilst attempting to accelerate
    PutImage.

    uxa: Don't treat prepare_access as a flush synchronisation point.
    
    The kernel will only emit a flush iff the buffer is currently owned by
    the GPU. Instead of presuming that the kernel must emit a flush, it is
    safer to assume that it does not and so cannot mapping the buffer on to
    the CPU as a synchronisation point. The most obvious counter-example is
    when we map the same buffer twice without using it in a batch.

    uxa: Limit maximum size of tiled objects
    
    On older chipsets (i.e. pre-i965) tiling is very restrictive and imposes
    severe size and alignment constraints. Combine that with relatively
    small apertures and it is very easy to create a batch buffer that
    cannot be mapped into the aperture (but would otherwise fit based purely
    on total object size). To prevent this we need to not use tiling for large
    buffers (the very same buffers where tiling would be of most benefit!).

    uxa: PutImage acceleration
    
    Avoid waiting on dirty buffer object by streaming the upload to a fresh,
    non-GPU hot buffer and blitting to the destination.
    
    This should help to redress the regression reported in bug 18075:
    
      [UXA] XPutImage performance regression
      https://bugs.freedesktop.org/show_bug.cgi?id=18075
    
    Using the particular synthetic benchmark in question on a g45:
    
    Before:
       9542.910448 Ops/s; put composition (!); 15x15
       5623.271889 Ops/s; put composition (!); 75x75
       1685.520362 Ops/s; put composition (!); 250x250
    
    After:
      40173.865300 Ops/s; put composition (!); 15x15
      28670.280612 Ops/s; put composition (!); 75x75
       4794.368601 Ops/s; put composition (!); 250x250
    
    which while not stellar performance is at least an improvement. As
    anticipated this has little impact on the non-fallback RENDER paths, for
    instance the current cairo-xlib backend is unaffected by this change.

    As we track when a pixmap is active inside a batch buffer, we can avoid

    i915: Use the color channels to pass along solid sources and masks.
    
    Instead of allocating and utilising the texture samplers for 1x1R
    solid sources and masks we can simply use the default diffuse and
    specular colour channels and adjust the fragment shader appropriately.
    The big advantage is the reduction in size of batches which should give
    a good boost to glyph performance, irrespective of the additional boost
    from using simpler shaders.
    
    However, the motivating factor behind the switch is that our use of 1x1
    textures turns out to be buggy...

    Since batch buffers are rarely emitted by themselves but as part of a

    uxa: Force alpha bits to fill remaining bits
    
    In the case of x8r8g8b8 and similar where the alpha channel is ignored,
    but should be interpreted as being 1, then it is convenient if those bits
    are set appropriately in the colour. In order to do so for these formats,

    width as the remaining bits instead.

    Xv: rework overlay buffer management
    
    The basic idea is to only pin the buffer into the gtt when
    the overlay hw is actually using it. This results in a few changes:
    
    - Unify data copied/buffer handling with textured video. Now offsets
      are always buffer relative and we just use drm_bo_map to access a
      buffer.
    - Implement double buffering using two bo's. This is necessary because
      we can't pin the same buffer to the gtt and map it as normal memory.
    - Kill XV_DOUBLE_BUFFER. With the above changes, overlay video is always
      doubel buffered.
    
    There is still the XvMC passthrough case, which makes the code slightly
    ugly. Unfortunately we can't get at the bo behind this buffer.
    
    Changes since the last review-round:
    - Don't overallocate by a factor of 2.
    - Prevent possible use-after-free issue.

Date:   Tue Aug 11 16:06:36 2009 +0200

    Xv: kill hw double buffering logic
    
    The idea for the hw double buffering support is to program two fixed
    buffers and then only switch buffers in the OCMD register. But the driver
    as-is always programs the new buffer address (in both register sets
    when double buffered). Therefore we gain nothing by using this hw
    capability. Scrap the software support for it.
    
    When double buffered, we now allocate just a buffer of size 2*size and
    switch between the two parts purely in software.
    
    To make reviewing this easier, I'll shortly explain the differences of how
    double-buffering (i.e. tear-free video) is achieved before and after this
    change:
    
    - When double buffer, allocate a buffer twice the size (unchanged).
    - Depending upon the currently shown buffer-half, copy the new frame into
      the other buffer-half. In the old code this is done by using the right
      set of buffer offsets, either *Buf0Offset or *Buf1Offset. The new code
      simply programs the offset for the right buffer-half into the single set
      of offsets. The end-result is unchanged.
    
    Now the big difference in hw-programming:
    
    Old: Programm new buffer offset into both sets of _hw_ buffer offset
    registers. Depending upon the current _sw_ buffer, select the _hw_ buffer
    and program this into the OCMD register. This just complicates matters
    unnecessarly.
    
    New: Just always use the hw buffer 0.
    
    And then it's again the same story in both old and new code:
    
    - Execute an overlay flip (MI_OVERLAY_FLIP) to read in the contents of the
      hw registers into the shadow hw registers (which are actually being used
      by the overlay, not the ones we write stuff into). This is synchronized
      with the respective crtc vblank by the hw.

    does not make sense, here's why:
    
    XvMC is everywhere else handled as a planar format (e.g. in the register
    programming a few lines down). Furthermore the id variable gets mapped
    to FOURCC_YV12 if IS_I915(pI830) is true in I830PutImage. There's a
    second caller in the offscreen overlay support code.  But I think that
    code is bitrotten and not reliable as an information source.
    
    So we have a different behaviour only for id=FOURCC_XVMC and i965 class
    hw (i830 class doesn't have xvmc). I've crawled through various
    sources/intel documentations. Finally in the textured video implemention
    for i965 class hw (src/i965_video.c) I've found a switch statement that
    puts XVMC into the same case as I420 and YV12. So also in i965 class hw
    xvmc uses a planar format.
    
    In conclusion I claim that this code was bogus and XvMC on i965 class hw
    over Xv overlay was most likely broken.

    Remove DGA support from the driver.
    
    The xf86DiDGA code required that the scanout buffer always be
    mappable, stay be at a fixed address in the aperture and have a
    constant size. With frame buffer resizing, the latter two are no
    longer true, and with KMS, we'd really prefer to not allow the former.
    
    The only option available to the driver is to completely disable DGA
    as the modes code has internal calls to the xf86DiDGA code when
    fetching new modes from the hardware.
    
    A fix for the DiDGA code will be added to the X server which will
    automatically initialize DGA for mode switching and input, but not
    frame buffer access, and not require any driver cooperation.
    
    Thus, the correct solution is for the driver to not call xf86DiDGAInit
    at all. For old servers, this eliminates a potential catastrophic
    problem where random memory is written by the X server. New servers
    will get the DIX-based behaviour automatically.

    Remove vestigial internal rotation which broke KMS DGA/VidMode modesetting.
    
    Pre-2.0, the driver supported rotation internally, rather than relying
    on the X server rotation support. The last piece of this dealt with
    rotating the mouse coordinates and also tried to preserve rotation
    across DGA/VidModeExtension modesetting requests.
    
    That latter bit of code broke under KMS as the rotation value was
    never initialized, and when set to zero would create an invalid
    configuration. This would confuse xrandr which would bail before
    making any changes, leaving the user without a way to recover.

    Avoid fallbacks for a1 src/mask
    
    Carl Worth did the hard work in identifying that the regression in
    cairo between X.org 1.6 and 1.7 was caused by cairo sending an a1
    mask to the server in 1.7 whereas in 1.6 cairo used local fallbacks
    (as the source was using RepeatPad, which triggers cairo's
    'buggy_pad_reflect' fallback for X.org 1.6). This was causing the driver
    to do a fallback to handle the a1 mask instead, which due to the GPU
    pipeline stall is much more expensive than the equivalent fallback in
    cairo.
    
    Reference:
      cairo's performance downgrades 4X with server master than server-1.6.
      https://bugs.freedesktop.org/show_bug.cgi?id=23184
    
    The fix is a relatively simple extension of the current
    uxa_picture_from_pixman_image() to use CompositePicture() instead of
    CopyArea() when we need to convert to a new format.

    Don't destroy bufmgr at CloseScreen time
    
    Under KMS, the bufmgr is not initialized at InitOutput time and so it
    won't be re-initialized during server regen. Thus we must leave the
    bufmgr running during regen and cannot destroy it in CloseScreen.
    
    Under UMS, each place the bufmgr is initialized, it checks to see if
    it has already happened. Hence, we can safely leave the bufmgr running
    across server regen for UMS too.

    Avoid fallbacks for compositing gradient patterns
    
    Currently when asked to composite using a gradient source or mask, we
    fallback to using fbComposite().  This has the side-effect of causing a

    like uxa_trapezoids(), we can use pixman to fill a scratch pixmap and then
    copy that to an offscreen pixmap for use with uxa_composite().

    we remove UMS, this patch adds a build time flag to allow the driver to
    assume KMS support.
    
    With this flag active, the driver will not request that I/O or MEM be
    enabled at probe time, which can allow the server (if other drivers also
    cooperate) to run as a non-root user.

    The 965 docs note, and it's probably the case on 915 as well, that the
    2x2 subspans are read as a unit, even if the bottom row isn't used.  If
    the address in that bottom row extended beyond the end of the GTT, a
    fault could occur.

    Fix sampler indexes on i965 planar video.
    
    We only set up one sampler, because all of our sampling is the same.  By
    using a non-zero index for the other two samplers, we'd dereference (likely)
    zeroed data, resulting in using NEAREST filtering.  This was a regression in
    40671132cb3732728703c6444f4577467fa9223f which incidentally switched from
    having 6 samplers to 1.

    Calculate the DVO relative offset in LVDS data entry to get the DVO timing
    
    Now the DVO timing in LVDS data entry is obtained by using the
    following step:
        a. get the entry size for every LVDS panel data
        b. Get the LVDS fp entry for the preferred panel type
        c. get the DVO timing by using entry->dvo_timing
    
        In our driver the entry->dvo_timing is related with the size of
    lvds_fp_timing. For example: the size is 46.
    
        But it seems that the size of lvds_fp_timing varies on the differnt
    platform. In such case we will get the incorrect DVO timing because of
    the incorrect DVO offset in LVDS panel data entry.
    
    Calculate the DVO timing offset in LVDS data entry to get the DVO timing
        a. get the DVO timing offset in the LVDS fp data entry by using the
    pointer definition in LVDS data ptr
        b. get the LVDS data entry
        c. get the DVO timing by adding the DVO timing offset to data entry

    i830_bind_memory: Under UMS: Bind GEM bos with dri_bo_pin, else through the GART
    
    We only need to get static offsets for objects when not running KMS,
    otherwise the kernel will manage those as needed for us.
    
    Binding objects is done in one of two ways. For GEM buffer objects, we use
    dri_bo_pin. For GART allocated memory, we bind that to the GART.

    Allocate GTT space for GEM only under UMS
    
    GEM requires GTT space to map objects. Under KMS, the kernel driver has
    already provided all available GTT space to GEM, so the X server need not do
    anything.

    Always set screen pixmap data pointer at init and resize times
    
    For non-DRM environments, the screen pixmap will be GART allocated memory
    and not a libdrm buffer object and so uxa will only use devPrivate.ptr to
    find the associated memory. Make sure devPrivate.ptr is set each time the
    framebuffer is allocated so that uxa will be able to draw to it.

    non-DRI FB resize failed to assign the screen pixmap devPrivate.ptr (22328)
    
    When not using DRI, the screen pixmap is not in a bo, and so the usual
    enable/disable access functions don't adjust the pixmap devPrivate field,
    leaving it to the frame buffer allocation code to assign this correctly.
    
    During mode setting and fb resizing, FB access is disabled, and the
    screen pixmap devPrivate is stashed away by xf86EnableDisableFBAccess,
    to be restored when FB access is turned back on. This means that we have to
    set the pixmap devPrivate.ptr (in case xf86EnableDisableFBAccess doesn't
    do this), along with storing the address in the scrn->pixmapPrivate field.

    Fix segv for clipped movie window
    
    When playing a movie that is clipped on its left and right edges the Xorg
    server will SEGV sometimes. This is because the intel driver ignores the
    clipping info when it copies the planes out of the XV data.
    
    The check for the optimised copy was wrong to ignore the width required.
    Which leads to too much data being copied by the memcpy. It the source buffer
    happens to end exactly on a page boundary the server will SEGV.
    
    As we reviewed the code we checked the calculation of src1, src2 and src3.
    The patch includes additional comments to make it clear what the elements of
    the calculation are.
    
    This bug exists in git head and we also see it in 2.4.1.

    Otherwise we may end up returning a false positive if some other output & crtc

    Treat disabled CRTCs as "not covering" for scanline wait purposes
    
    Now that swapbuffers does a scanline wait to avoid tearing, it's
    important to take into account the CRTC status to avoid hangs.  If we
    do a scanline wait when the CRTC is off (due to DPMS for example) we'll
    hang the GPU.  So add some code to check the CRTC DPMS status to the
    i830_covering_crtc function, returning NULL if none of the covering
    CRTCs are actually active.  KMS vs UMS logic is hidden in new i830*
    functions, cleaning up both DRI2 & video paths a bit.

    UXA: Rasterize trapezoids to system memory, not a pixmap
    
    Since we're only doing software rasterization right now, anyway, it
    makes more sense to just rasterize to system memory and then upload
    to a pixmap once complete. This avoids expensive read-modify-write
    cycles.
    
    This results in a 2.4x speedup for a real-world test case that's
    heavy on trapezoids, which is swfdec running on the following file:

    Fall back to fb pixmaps for backing glyph pictures
    
    GEM pads pixmaps to 512 byte stride and backs them with a kernel side
    buffer objects.  We typically don't render out of glyph pictures, so
    we're incurring a lot of overhead per glyph by allocating a GEM pixmap
    per glyph.  By looking at the usage hint, we can fall back to
    fbCreatePixmap for pixmaps backing glyph pictures, which gives us
    a nice tight malloced pixmap.  The fast path for text rendering is
    compositing from the glyph cache pixmap to the destination, which
    shouldn't be significantly affected.
    
    Quick bit of testing:
    (firefox-20090601)
        xlib-rgba-before    384512.49:  1.01x
        xlib-rgba-after     389633.94:  1.00x
    The difference being within the margin of error for the benchmark.

    Wait doubled regis to be stable for load pipe detection
    
    We have two approaches for VGA detections: hot plug detection for 945G onwards
    and load pipe detection for Pre-945G. load pipe detection will get one free
    pipe ,and set border color as red and blue, then check CRT status by
    swf register. Because pipe registers in hires mode are double buffered,
    once set force border bit in pipeconf register, we have to wait for
    a vblank until it is effective, otherwise result is unstable.

    Set activation periods as 64 cdclk sync up with KMS
    
    We use force CRT detect trigger bit(1 << 3) to detect VGA in hot plug mode,
    which triggers a CRT hotplug/unplug detection cycle independent of the
    interrupt enable bit(1 << 9), so keep bit 9.
    And although spec says CRT_HOTPLUG_ACTIVATION_PERIOD_64(1 << 8) is only useful
    for mobile platform, it is also required to detect vga on G4x platform correctly.
    Tested the patch on G45/G43/Q45 platforms with no regressions
    
    It fixed freedesktop.org bug #21120 and part of bug #21210.

    Open the DRM and keep the handle throughout server startup to finish.
    
    This will let us configure the server from start to finish with the
    most pertinent information available (KMS vs UMS, DRI2 vs non-DRI).  Also,
    we now close the DRI2 fd at terminate, which we didn't before.
    
    This duplicates some code from DRI1 for getting a master FD like I'd done in
    DRI2, but given that we weren't loading DRI1 ourselves, this is also a
    bogosity cleanup, and avoids allocating the extra DRI1 private.

    Don't do GTT maps on objects bigger than half the available aperture size.
    
    The basic problem is that software fallbacks will do single instructions that
    copy from one GTT-mapped BO into another GTT-mapped BO.  If we can't get both
    of them bound simultanously, we fault one in, retry the instruction, fault the
    other in (kicking out #1), retry the instruction, fault #1 back in
    (kicking out #2), etc.
    
    Note that we'll still get into a nasty spot if you do a composite operation
    with a mask where all 3 are big-but-less-than-half-available-aperture, where
    you'll thrash.  It at least means you'll make progress, though, since each
    instruction will only be operating on two BOs at at time, and the situation
    seems unlikely.

    Prior to this patch, code that wanted to check whether GEM was present

    the hoops that must be jumped to use that kernel interface successfully.
    Yet we continued to use it even with KMS/DRI2/UXA, which may account for
    some hangs.

    Replace i830WaitSync with just I830Sync(), as nearly all callers had it wrong.
    
    People were trying to BEGIN_BATCH()/ADVANCE_BATCH() then i830WaitSync on the
    results, which wouldn't necessarily wait and lead to various painful bugs,
    since only EXA called MarkSync and only for certain rendering operations.

    Remove EXA support.
    
    UXA has completely replaced EXA at this point.  UXA is the same rendering
    core as EXA, but relying on kernel memory management or a fake bufmgr instead
    of trying to manage memory in the X Server.

    While EXA/UXA aren't completely good replacements (see bugzilla for
    performance and stability problems), we are pretty sure at this point that
    it's the right way to go and that having multiple acceleration architectures
    is getting in the way of producing a stable codebase.

    Fix assert at startup with DRI initialiation failure.
    
    In this path, we'd make it to allocator_init -> init_bufmgr without
    GEM and without FbBase being initialized, leading to assertion failure
    to catch this mistake.
    
    Comedy ensued when trying to move just the MapMem up, leading to the rest
    of the commit.  Some day (like tomorrow after I rebase intel-cleanup) I'll
    clean this path up.
    
    Tested with 2 X Servers on 2.6.28 (one gets DRI2, one fails successfully),
    2 UMS X Servers on 2.6.30rc2 (each gets DRI2), and 2 KMS X Servers on
    2.6.30rc2 (success all around).

    set broadcast RGB mode for HDMI and TMDS from SDVOX output
    
    Almost all digital TVs accept broadcast RGB values from 16 to 235 for each channel,
    otherwise for those uncompensated videos, when RGB values are set from 0 to 255,
    they will shows black and whiter clamping, which seriously degrades picture quality.
    The patch will enable the broadcast RGB mode for hdtv according to user's setting.
    It fixed bug #14486

    Don't enable kernel execbuf fencing w/EXA
    
    If we enable kernel execbuf fence register management, it's best if the
    kernel manages all fence registers.  This works fine if the accel
    method is managing pixmaps or doesn't use offscreen pixmaps.  However
    with EXA, pixmap accesses are done relative to the framebuffer BAR
    mapping (pI830->FbBase) and the Screen pixmap address.  So if we try to
    set the screen pixmap to point at a GTT mapped (and therefore properly
    fenced) address, later calls to intel_get_pixmap_offset() will call
    into EXA, which will use the pseudo-random pixmap addr and the EXA
    offscreen base addr (which is really just FbBase) to calculate the
    offset.  This will fail.  So disable kernel fence reg management in the
    EXA case (this is easier than adding proper EXA pixmap management to
    xf86-video-intel, and makes more sense since we'll be removing EXA soon
    anyway).
    
    Fixes FDO #21027.
    
    Also happens to fix FDO #21029 (as tested by Carl Worth <cworth@cworth.org).

    Fix value for MI_WAIT_FOR_PIPEA_SCAN_LINE_WINDOW
    
    Since the change to scan-line based video sync, (rather than vblank-
    based), we've only been getting tear-free video on one of the two
    pipes. This fixes that bug by using the correct constant for waiting
    on PIPEA.

    Don't clip video to CRTC in the case of textured video
    
    Since we're not limited by a single overlay plane on a single pipe,
    we want to not clip at all, (so that the correct video appears on
    both pipes).
    
    This fixes bug #20980 which shows a video spanning two pipes
    being rendered incorrectly.

    Remove support for 'auto'(-1) value of XV_SYNC_TO_VBLANK
    
    We previously had a heurstic here where we would only sync to vblank
    for windows that covered more than 25% of the screen. We don't need
    this anymore since the new approach to sync, (WAIT_FOR_SCANLINE_WINDOW),
    is not excessively costly for small windows.

    Use WAIT_FOR_SCAN_LINE instead of WAIT_FOR_VBLANK
    
    Either way, the goal is tear-free video playing. But waiting for
    a scan-line window not only has the advantage of being cheaper
    for small windows, but also avoids hanging the GPU in the case
    of the pipe getting turned off, (by screensaver, for example),
    while a batch is waiting for a VBLANK that will never occur.
    
    This fixes that GPU hang.

    Non-GEM allocations incorrectly force TILE_NONE (bug 20797)
    
    With -intel 2.6.3 performance was very bad when using a non gem enabled kernel
    (2.6.27) and EXA. For example sauerbraten ran with 4 fps and screensaver GLBlur
    with 1 fps. With -intel 2.6.1 performance was good using the same kernel.
    
    Git bisecting led me to commit f1ed73c1ef3e3daa9f695194dcc813167cbcb53d (in 2.6
    branch) "Make i830_allocate_memory take tiling parameters" as first bad commit.
    
    Using gdb I found tiling was set exactly the same in 2.6.3 as in 2.6.1, so that
    was good (TILE_XMAJOR for front, back and depth buffers).
    Looking further I found the line mem->tiling = TILE_NONE; (line 961 in
    src/i830_memory.c) at the end of i830_allocate_memory suspicious, as
    mem->tiling now already gets set via i830_allocate_aperture and some buffers do
    have tiling. Removing that line indeed fixed the performance issue. Now
    sauerbraten runs with 30+ fps and GLBlur runs smoothly.

    Tiling fixes, third set
    
    Hopefully this concludes the fixes necessary to deal with the various
    combinations of kernel and user level tiling.  We have several cases to
    handle:
      1) KMS (kernel handles all tiling)
      2) UMS w/memory management + kexec fencing (kernel handles all tiling)
      3) UMS w/memory mangement but no kexec fencing (userland handles tiling)
      4) UMS w/o memory management (userland handles tiling)
    
    For cases (1) & (2) we can use GTT mapping, which will give us good
    performance and take care of allocating fence registers as needed.  It's
    important *not* to have userland set up fence regs in this case, since
    the kernel will be using all of them.
    
    For case (3), we use the begin/end GTT map functions provided by libdrm,
    in combination with pinning and fence register setup in i830_memory.c to
    deal with tiled surfaces.  This also gives us good performance and
    correctness.
    
    For case (4) we use the old style virtual mapping + offset for dealing
    with surfaces; note that UXA doesn't seem to work in this configuration
    regardless of these fixes.
    
    Fixes bug #20803.

    Don't install fences if the kernel is managing them
    
    If execbuffer is setting up fences, it also means that the kernel is
    managing them at pin time, so installing one in the 2D driver in that
    case is an error.  The fence should stick around as long as the buffer
    is pinned (the kernel won't steal these), though it will be freed at
    leavevt and re-allocated at entervt.
    
    On 965+ chips, the pin ioctl will *not* install a fence reg, but that's
    also ok because all 965+ operations include tiling bits, and sw
    fallbacks will be protected by prepare/finish access hooks, which will
    either access the backing store or use the GTT, which will ensure proper
    fencing at fault time.
    
    Fixes #20265.

    With glyphs sitting in per-glyph pixmaps, there's no reason to use the CPU
    to move them to the cache pixmap, and lots of reasons to use the accelerator.

    Revert "SDVO: Switch control bus only before DDC access"
    
    This reverts commit ddedf19f889da2ce6d69a3afce4665e2245682fa.
    
    After i2c STOP, control bus will return back to internal
    registers. So this brings back to origin code that we switch
    to DDC bus before START. But it's ideal to only issue DDC
    bus switch after STOP, not before every START, which might eliminate
    some complains from SDVO device, that will be another patch later.

    Fix XV with non-GEM kernels by allocating a larger fake bufmgr.
    
    Ideally we'd not be using the EXA offscreen memory manager and just hand all
    that memory to the fake bufmgr for non-GEM, but the fake bufmgr's too slow for
    that, at least currently.  So compromise and take enough memory that it will
    succeed at XV allocations but hopefully not anger tiny-aperture systems too
    much.

    TV: update output and crtc modes when TV format change (try 3)
    
    This is to fix bug #16566, change TV format will cause BadMatch
    error when crtc config apply. Everytime when we change TV format,
    we may generate a new list of modelines as TV clock changed. After
    randr get info request, new modelines will be probed and randr output's
    modes will be renewed too. But crtc's mode failed to be updated,
    as it never can find a matching mode now within new modes list.
    So get info will return an invalid crtc's mode, later set crtc
    config will pass that info, and xserver catches a bad match.
    
    This patch trys to refresh output modes and setup crtc's mode
    with new modelines in TV format change. So get info would be
    sure to turn valid crtc mode that reference in current new modelines.

    Simpler and more robust.  Works when we haven't set the device PCI ID,
    ie when not going through the legacy DRI module.

    SDVO: Fix TV support
    
    As SDVO TV uses SDVO_TVClkIn from SDVO encoder for clock reference,
    it needs to generate proper PLL for current input clock. This uses
    fixed PLL table from vbios for this. And possible sdvo mulitiplier
    has to be setup correctly. This makes TV output stable on my 945GCLF2
    board with NTSC-M format.

    Don't run in KD_TEXT mode even with KMS
    
    Leaving the VT in KD_TEXT mode keeps the kernel's blanking code active,
    so when a DPMS event happens, the fb console is restored rather than X's
    configuration.  On the downside it means the kernel won't print messages
    in the background, which would be visible if a panic or emergency switch
    occurred.  The proper fix here is a new kernel mode, which we can move
    to when ready.

    The require_space had failed since it only checked for the space required
    by the batch emits in the function itself, but not in the
    i965_emit_composite_state() that it called (the state we were concerned about
    having set up for that 12 * 4 dwords to follow!).  This is replaced by
    intel_batch_start_atomic(), which will catch such mistakes in the future.

    Support sysfs backlight control for Sony laptops in xf86-video-intel
    
    The sony_laptop kernel module (since v2.6.23) supports backlight control
    via the sysfs interface:
    /sys/class/backlight/sony
    
    This patch will enable xf86-video-intel to use this backlight control method
    for Sony VAIO Laptops with Intel integrated video.

    intel: fix DRI2 should be DRI_DRI2

    Re-emit i915 composite setup when the batchbuffer wraps.
    
    This also introduces tests to make sure that we asked for enough reserved space
    and that we don't allow wrapping at the wrong time.
    
    This fixes a hang during text rendering with DRI2 and a GL client running,
    but could potentially affect text rendering with GEM in general with an
    exceptional batchbuffer setup.

    Assign rotation memory dri_bo to rotation pixmap.
    
    As the rotation memory and rotation pixmap are allocated separately (to make
    rotation at startup work), the allocate dri_bo needs to be set in the pixmap
    for acceleration to work. This restores the performance in rotated modes.

    If the EDID data from the LVDS doesn't indicate support for a wide range of

    uxa: Do a hack to use the aperture mapping instead of bo_map in sw fallbacks.
    
    Because of how fallbacky the uxa rendering core is, and our inability (without
    wfb in userland or page faulting in the kernel) to tell the kernel just where
    we're going to fall back, the clflush overhead can become outrageous, for
    example with emacs and xcompmgr.  Instead of using drm_intel_bo_map, pin the
    buffer and do the fallback to the aperture mapping.  This gets us the bad old
    performance that fb is designed for, instead of bad new performance.

    that's really slow. Providing set_origin makes it nice and snappy.

    Set vertex_buffer_bo to NULL after unreference.
    
    Which is just being tidy. We initially were looking at this code
    path due to a report of a crash on server shutdown which started
    after this unreference call was added. Setting this to NULL
    apparently didn't avoid the crash, but it's a good thing to do
    regardless.

    Don't smash fixed_mode if skip_panel_detect is set.
    
    Without this change, setting LVDSFixedMode to false is not effective
    as i830_bios_init calls i830_parse_panel_data which in turns sets
    a fixed_mode. To fix this we still call parse_panel_data to set
    the various lvds_options but we return before setting fixed_mode.

    i965: Add batch_flush_notify hook to create new vertex-buffer bo
    
    This avoids mapping a buffer object which is being referenced
    by a batch that has already been flushed, (which is a terribly
    expensive operation).
    
    On my machine this brings the performance of x11perf -aa10text
    from 85k back to 150k, (where it was before a recent kernel
    upgrade). Also, before this patch, when I used my X server
    actively performance would drop as low as 15k---hopefully that
    bug is gone with this change.

    now using ACPI.  Additionally, some machines apparently get stuck with the
    event set and end up DDCing checking for new devices every second and
    smashing your video modes.

    Use buffer objects for binding table and surface-state objects.
    
    Instead of having a static array for these and doing an ugly sync
    everytime we recycle the array, we now simply allocate short-lived
    buffer objects for this dynamic state. The dri layer, in turn, can
    take care of efficiently reusing objects as necessary.
    
    On a GM965 this change was tested to improve the performance of
    x11perf -aa10text from roughly 120000 to 154000 glyphs/sec.

    965: Move composite setup to new _emit_batch_header_for_composite
    
    This function is the new name for _allocate_dynamic_state now that
    it also emits everything to the batch necessary for setting up a
    composite operation. This happens in prepare_composite() every
    time and in composite() whenever our vertex buffer fills up.
    
    It's not yet strictly necessary to be redoing this setup in
    composite() but it will be soon when the setup starts referring
    to buffer objects for surface state and binding table. This
    move prepares for that.

    Use buffer object for vertex buffer (in new gen4_dynamic_state)
    
    This begins the process of separating the dynamic data from the
    static data, (still to move are the surface state and binding
    table objects). The new dynamic_state is stored in a buffer
    object, so this patch restores the buffer-object-for-vertex-buffer
    functionality originally in commit 1abf4d3a7a and later reverted
    in 5c9a62a29f.
    
    A notable difference is that this time we actually do use
    check_aperture_space to ensure things will fit, (assuming
    there's a non-empty implementation under that).

    out from that).
    
    Again, no intended change in functionality here.

    Rename gen4_state_t to gen4_static_state_t
    
    It doesn't contain only static data yet, but it will soon, so
    this renaming prepares for that. Also, this helps make things
    more clear between gen4_render_state_t and gen4_state_t which
    were muddled before, (particularly because the corresponding
    identifiers were render_state and card_state). The card_state
    identifier is now known as static_state which should be less
    confusing.
    
    This change is strictly search-and-replace with no functional
    changes.

    Fix broken stolen memory counting on G4X.
    
    On the GM45 we were assuming too little stolen memory (mostly harmless,
    except when it wasn't, until the AGP fix), and on the G45 we were assuming too
    much stolen memory, which was quite harmful when we touched the page that
    didn't get mapped.
    
    Future stolen memory accounting should use src/reg_dumper/intel_gtt before and
    after enabling AGP on the chipset to confirm that only the GTT entries not
    mapped to stolen are replaced, and that all of the unmapped GTT entries are
    replaced with the constant scratch page.

    For non-DRM, add NOOPs after BATCH_BUFFER_START to verify completion
    
    In non-DRM mode, the driver waits for the hardware by checking the ring
    pointers; when the ring is empty, it assumes the hardware is idle. However,
    the hardware updates the ring pointers before executing a command, so if the
    MI_BATCH_BUFFER_START is the last command in the ring, the driver will think
    the hardware is idle while it may still be processing the contents of the
    batch buffer. Placing NOOPs after the BATCH_BUFFER_START allows the driver
    to know that the hardware has completed the batch buffer.

    Document and use 'legacy' border color mode

    mode since it's exactly what is specified by the Render extension.

    Fallback to software for RepeatNone with transformed RGB-only pictures.
    
    We wish it wouldn't, but the hardware ignores the alpha in the
    BorderColor we set when the source picture format has no alpha
    in it, (and it uses alpha of 1.0 where we want 0.0). For now,
    fallback for these cases. This gives a correct result, but
    obviously is not as fast as we would like.

    Work around libpciaccess reporting a 0 rom size by guessing.
    
    I required the following patch on top of this to work around libpciaccess
    brokenness.  libpciaccess reports 0 rom size if there's no rom resource,
    even if the rom file exists in sysfs.

    Eliminate INT10 call to get BIOS contents
    
    libpciaccess (and the old X server PCI code as well) provides a function to
    get the ROM contents. Code to use that was already present in the driver and
    used if the INT10 function failed. Skip the INT10 and just use libpciaccess
    as that eliminates several module loads and scary use of vm86.

    Prefer repeatType field over using both repeat and repeatType.
    
    Eric informed me that the repeat field exists only for backwards
    compatibility with old drivers that weren't prepared for values
    other than 0 or 1 here. Since we are, we can just ignore that
    field and examine only repeatType. So the code's a (tiny) bit
    simpler this way.

    Add support for RepeatPad and RepeatReflect.
    
    It's quite simple to support these modes---we simply need to
    turn on the support for them in the hardware.
    
    These changes have been verified with the extend-pad and
    extend-reflect tests in cairo's test suite. However, this
    currently required using a custom-modified version of cairo.
    The issue is that released versions of cairo, (and even
    cairo master so far), don't pass RepeatPad and RepeatReflect
    to Render, (due to various bugs and workarounds in cairo
    and pixman). I do plan to fix those issues in cairo, so that
    in a future release of cairo, (1.8.2 perhaps?), the cairo
    test suite will usefully test these new repeat modes in our
    driver.

    Examine picture repeatType as well as repeat field.
    
    The existing switch statement was switching on the Boolean
    repeat field rather than the correct repeatType field. This
    had not caused any problem before as only two possible repeat
    values were supported (RepeatNone = 0 and RepeatNormal = 1)
    so they were always the same as the repeat field.
    
    Soon, however, we'll be supporting more repeat types, so we'll
    need to switch on the correct value.

    Fix ordering of VGA vs. plane disable
    
    From the Intel 965 Programmer’s Reference Manual, volume 3,
    chapter 2.2.2 "Mode Switch Programming Sequence".
    
    The disable sequence should be:
    
     - Disable planes (VGA or hires)
     - Disable pipe
     - Disable VGA display in 0x71400 bit 31
    
    This patch implements that order plus waits for a vblank at the end.
    
    Fixes bug #17756.

    On some machines it appears that the LFP info pointers give us more

    Unfortunate mismatch between kernel and DRM master headers.
    Kernel:

    DRM master:
    typedef struct drm_i915_batchbuffer { ... } drm_i915_batchbuffer_t;
    
    so use the typedef rather than the morphing structure name.

    xf86SetDesiredModes() already sets lvds to full mode. later when
    xf86CrtcScreenInit() initialized randr12, i830_lvds_set_property will
    recall xf86CrtcSetMode and set mode to full. This patch is to remove the
    duplication. In my test, this can save about 0.2 - 0.4s x startup time.

    EXA and UXA have the same acceleration interface, but UXA doesn't provide

    reference the EXA structure.

    and puts the one with stencil (and depth) bits as first.

    Choose a split for DSPARB based on the configured modes for both planes.
    
    Previously, we were attempting to give both planes equal space in the FIFO

    on the relative HDisplay of the modes.  This should resolve some fifo underrun
    issues with differently-sized displays, or single large ones.

    Use up to 256 separate vertex buffers
    
    This allows us to only call i830WaitSync once every 128 calls to composite
    rather than on every call. However, we do need to also call MI_FLUSH to
    avoid the vertex cache getting in our way, (since our "separate" buffers
    are all allocated as one contiguous chunk).

    enough to handle the uncompresed buffer, both in terms of vertical size and
    total framebuffer size, or the compressor could overwrite the memory
    immediately following the compressed buffer.

    There are some concerns with this, as the DRM will be setting the nonsecure
    flag on the batchbuffer, and the server may be submitting some secure-only
    commands.  It appears to work on the 915GM test system currently.

    Avoid needless flush emits in the blockhandler.
    
    The EmitFlush in i830_dri.c was added as a pageflipping workaround, and was
    noted to not even be sufficient then.  There's no reason for it to be there,
    so it's removed.  After that, we just have to not emit an MI_FLUSH if we
    already had, and cursor movement no longer bashes memory manager.

    Use batchbuffers instead of ring emits for general commands.
    
    The batchbuffers are managed using libdrm and bufmgr_fake, and dispatched from
    the ring from userland.

    It turns out 855 has a different DSPARB layout than 915+.  And 945+ have more

    FIFO evenly again between A & B planes, and do the same on 945, where we have a
    larger FIFO.  Fixes an issue reported by Daniel Stone with the previous default
    value.

    Implement option to ignore external fixed mode settings
    
    The Intel xorg driver tries mightily to determine the native fixed
    panel mode settings for the LVDS output.  It does this through various
    means, including scanning video BIOS tables, and noticing if the pipe
    in question has already been set up by somebody else (and adopting
    those timings).  This strategy works well for say a laptop where the
    LCD panel is an integral part of the machine.  But for other
    applications where the display is unrelated to the system's BIOS or
    other software, then the BIOS will likely have no clue how to
    configure the LVDS output.  Worse still, the BIOS can simply "get it
    wrong", leaving the pipe misconfigured.  Unfortunately the Intel
    driver can potentially notice this, adopt the same settings, leaving a
    messed up display.
    
    All of this complexity normally happens independently, behind the
    scenes, from the mode timings that might otherwise be specified by the
    user.  This driver has a concept of fixed, i.e. "native" mode, and
    then user-specified mode.  If the corresponding resolutions between
    those concepts don't match, then the driver in theory will arrange for
    scaling to take place while adhering to the actual native mode of the
    panel.  Said another way, if the user says 800x600 but the driver
    mistakenly (see above) thinks the native mode is 640x480, then 640x480
    is the mode set with scaling to an 800x600 frame buffer.  If the
    driver gets the wrong native mode, then the result is a miserable mess
    with no way for the user to override what the driver thinks is right.
    
    This patch provides a means to override the driver.  This implements a
    new driver option, "LVDSFixedMode" which defaults to true (the normal,
    probe-what-I-need behavior).  However when set to false, then all the
    guessing is skipped and the driver will assume no fixed, i.e. "native"
    mode for the display device.  Instead with this option set to false,
    the driver will directly set the timings specified by the user,
    providing an escape hatch for situations where the driver can't
    correctly figure out the right mode.
    
    Under most scenarios of course, this option should not be needed.  But
    in situations where the Intel video BIOS is hopelessly fouled up
    related to the LVDS output, this option provides the escape hatch for
    the user to get a working display in spite of the BIOS situation.

    Set pin alignment for gem on non-965
    
    non-965 tiled frame buffers have fairly strict alignment requirements, 512K
    on 8xx and 1MB on 9xx, plus they must be aligned to the size of the
    allocation.

    Add a new quirk for BIOSes that reprogram regs at lid close/open time
    
    Dell Latitude D500s seem to have this problem.  At lid close/open, the DSPABASE
    reg gets reset to 0, so we either need to keep the framebuffer at offset 0 or
    make sure we reprogram the CRTCs after the lid opens again.  Since we can't
    make sure the former is always true (buffer resize, etc.), this patch adds a
    quirk to reset the modes at lid open time.
    
    Fixes FDO bug #14890.

    Add a kludge-around to fix cd/wt bits in fb ptes on linux.
    
    Mmap from /sys/devices/pci* on linux forces the cache-disable and
    write-through bits, which turns our write-combining map into an
    uncached-map, seriously impacting performance. It turns out that a bug in
    mprotect allows us to fix this by disabling access to those pages and then
    immediately re-enabling them.

    Kludge to make planar video work - duplicate sampler state
    
    This patch duplicates all of the surface sampler state needed to read from
    the separate YUV surfaces and then has the planar sampler read from samplers
    0, 2, 4 instead of 0, 1, 2. This appears to make things work, instead of
    having the samplers break at random. I do not understand why this works.

    We need one for each possible combination of src and dst

    to instead simply reference an existing object initialized
    within gen4_state_init.

    The YUV->RGB code was written to write directly to the dataport registers,

    This change makes that code write RGB values to the src_sample registers as
    with the other sample computation fragments.

    Compute pixel values directly into data port
    
    Instead of leaving pixel values in src_sample registers, compute the pixel
    values directl to the data port to save 8 moves. This cannot work when no
    computation is done as there is both no way to wait for the sampler to
    finish and because the sampler returns data in a different order from that
    required by the data port (sigh).

    Implement support for 24 bit pixel format
    
    The Intel driver appears to be coded to only work with displays
    expecting 18 bit pixels.  However I have an application using a LCD
    display that expects pixel data in 24 bit format.  The difference is
    only 2 bits in a single GPU register.  This patch implements that
    change, controlled by a new driver option, "LVDS24Bit".  The default
    value is false, which is the previous behavior.  When set to true,
    then 24 bit panels should work (at least the one I'm testing here
    does).

    SDVO: Fix DDC bus selection based on output priority list.

    SDVO: Fix mixups with input and output channels.
    
    The 2-bit input_mask was actually an input count -- in0 is always there, and
    in1 is optional.
    
    The output flags weren't being reported in the log, so I mistakenly took
    controlled_output == RGB0 to mean that the device only reported an RGB0,
    while it actually reported RGB0|SVID0|YPRPB0|misc|other.  Move SVID0 up
    in priority and remove the RGB-is-it-really-TV hack I had just come up with.
    
    Finally, set the input/output mapping at mode set time.  We're always
    supposed to do this, but haven't had to so far as we've never handled
    devices with more than one output.

    Use combo backlight control rather than pure legacy
    
    If the legacy bit is set, use both the BLC_PWM_CTL and LBB regs to control the
    backlight, rather than just LBB.  Looks like more platforms want that than what
    the current code does.  Note that kernel provided interfaces will always be
    used if available, so this shouldn't affect users with /sys/class/backlight
    interfaces at all.
    
    Fixes #14721.

    Fix 965+ rendering issues with DRI disabled.
    
    The new chips no longer automatically flush the rendering cache, so if we
    don't flush the RC at blockhandler, the last rendering done may not
    appear on the screen.  This was particularly noticable with a bare Xorg with
    some missing root weave, and terminals where the last character wouldn't
    appear until the cursor blinked.  A flush in the DRI blockhandler path had
    hidden this issue for most people.

    for previous platforms as well to zero out the fields that should be zero

    Transformed coord computed using floats. Don't move bilinear composite dst.
    
    The homogeneous coordinate computation in the core server cannot be used for

    When compositing with bilinear filter, don't push the dst coordinates around
    as that makes the output blurry when pixels are aligned.

    When we have unset channels (color for a8, or alpha for x8*), force them
    to the appropriate value in the texture combiner rather than relying on getting
    the desired results from teture mapping.  Performance is the same on 865, so
    multiple paths aren't necessary and we can use the less friendly texture
    formats everywhere.

    Always bind memory after agp aperture allocation
    
    This fixed the crash appearing for Xv buffer memory, which appears
    allocation and free happening in stolen memory. We should always
    try to bind for stolen memory for correct protect setup, otherwise
    we might get fault that stolen memory protect reverted to non-r/w
    after previous free and unbind.
    
    Credit goes to Lukas Hejtmanek to identify the real problem of Xv
    crash!

    Eliminate local variables defined in i830 BEGIN_LP_RING().
    
    This lets us get better sanity asserts, and avoid mysterious braces when you
    do two BEGIN_LP_RING()s in a single function.  Potential minor performance
    loss isn't too exciting, as ring access is about to become a compat path
    anyway.  This change also removes the requirement for ring emits to be aligned
    to dwords.

    Silence warnings about possible uninitialize use of dst_format.
    
    Whoa, gcc got a lot smarter about warnings.  If iXXX_get_dest_format()
    doesn't support the picture format passed in it won't initialize the
    uint32_t pointed to by dst_format and return FALSE.
    
    What gcc now can detect is if dst_format is used without checking the
    return value, it might be used uninitialized.  This patch makes sure
    we always check the return value before using dst_format.

    Use the "immediate idle" mode for FBC.  Rather than waiting for the current

    idle right away.

    Bug 14032: i810, set default depth to 16
    
    X fails to start without an xorg.conf on i810, because the default depth set by
    the server (32) is not supported by the driver.  I think the driver should
    default to 16 bits (it supports 24, but when I tested it that didn't seem to
    work very well, and dri is disabled at 24 bits depth anyway) instead of letting
    the server use 32 and failing later on.

    Turn on backlight when LVDS panel is powered up
    
    In some configurations, the LVDS may be off at startup along with the
    backlight.  So when turning the LVDS on for the first time, we may also need to
    set the backlight to a non-zero value.  So try to use the saved value if
    possible, but if it's zero, make the backlight full brightness when turning on
    the LVDS.
    
    Note that this is slightly sub-optimal for configurations where zero is a valid backlight brightness.
    
    Fixes fdo bz #13958.

    Remove unnecessary quirk code in CRT probing
    
    Since we return early in the CRTC DPMS code, keeping the pipes & clocks

    should be reported correctly even when the pipe A quirk is active.
    
    Updates fix for fdo bz #11432.

    Add pipe A force enable quirk
    
    On some platforms, the firmware may read & write GPU registers on lid close,
    suspend/resume time or during various SMM events.  If one of the graphics pipes
    is disabled at that time, the GPU may hang due to the programming dependencies
    of the various registers.
    
    This patch adds a quirk to force the driver to keep pipe A enabled if
    necessary, through user configuration in xorg.conf or via a platform specific
    quirk.  Leaving the pipe enabled comes at a power cost however, so the quirk
    should only be enabled when strictly necessary.
    
    Fixes https://bugs.freedesktop.org/show_bug.cgi?id=11432.

    Don't modify low bit of BLC_PWM_CTL when using combo backlight control
    
    On some platforms, the low bit of BLC_PWM_CTL is wired as a 'max brightness'
    flag, rather than a regular part of the backlight duty cycle.  So when in the
    combo mode, divide the total number of backlight levels available by two
    (tossing one bit) and adjust the programming in the set_brightness routine.
    
    Note that platforms with this behavior may need quirks added so that they work
    by default.

    Fix compilation error when not using DRI
    
    This patch complements 88f8b688e2316ae4a1f7485f0010ce90de54783a which

    definition.
    
    When XF86DRI and _XF86DRI_SERVER_ are defined this header gets
    indirectly included through "i830_dri.h", thanks to "i830_common.h"
    which masquerades this problem as released in 2.1.0 and that manifests

    This is a partial fix for #13196, which covers both leaving pipes disabled at
    server exit time and problems with restoring the pipe configuration on certain
    chipsets.  It restores the pipe configuration unconditionally (previously we
    made sure the PLL was running and we weren't in VGA mode) but also adds some
    additional PLL settle time to the PLL register write paths.

    Avoids polluting the global namespace with such generic terms.

    Use "LEGACY" backlight method if backlight control is such
    
    This may regress the user experience a bit (fewer backlight levels) on machines
    where both the LBB and native registers work, but it's better that it work for
    everyone than work extra well for some and not at all for others.

    The PLL spreadsheet makes the precise register ranges allowed for each mode

    the gap we've seen in the reachable frequencies.

    Improve backlight control
    
    This commit fixes backlight support for several platforms.
    
    Except on recent machines supporting the IGD OpRegion specification,
    backlight control is rather platform specific.  In some cases, we can
    program the native backlight control regsiters directly without any
    trouble.  On others, we need to use the legacy backlight control
    register.  On still others, we need a combination of the two.  And on
    some platforms, none of the above will work, so we go through the
    kernel backlight interface, which provides a platform specific driver
    for backlight control.

    In the clock graph, draw the VCO as erasures in the lines representing clocks.
    
    This shows one of the reasons for the gaps: with the other settings, the VCO
    is too low inside the gap.  However, it also points out another issue: we
    aren't using the high end of the VCO range due to some other limits being hit.

    Fix palette save/restore
    
    When restoring the palette, we weren't checking to make sure the
    associated pipe was enabled before writing the registers.  In some
    configurations, this led to a driver crash.  Add new routines to handle
    palette save/restore and verify that the pipes are on before we touch
    the registers (could easily be changed to enable/disable the pipes
    around the save/restore as well).

    Move tiling fence register setup to bind time instead of allocate time.
    
    This allows us to allocate tiled buffers in buffer objects.  In the process
    I removed the fence division that we had for tiled buffers on pre-965.  If we
    resurrect that code, it should probably be managed by just dividing all the
    objects in roughly half and fencing those halves (to reduce the alignment
    requirement), instead of using giant fences until we run out of space and then
    trying to deal with scarce space on the last (or not) buffer.  Halving
    our tiled objects would use 6/8 of our fence registers on that hardware.

    Rework DRI buffer mappings and sarea setup to allow for moving buffers.
    
    While this has been a desired feature for some time, to allow for reallocation
    of the front buffer, it was made more necessary by the desire to avoid
    requiring a NO_MOVE buffer type in TTM because buffer objects may not be left
    pinned over VT switch.  This is a step towards making those buffers
    movable and resizable.

    Move drmMMLock to after we have unbound our (pinned) buffers.
    
    There are still issues due to the fact that we're allocating
    NEED_LIFETIME_FIXED memory as buffer objects, which we refuse to unpin because
    we have no way of pinning it back in the same location.

    Refuse to allocate LIFETIME_FIXED objects in buffer objects.
    
    We can't guarantee the offset will stay the same using the current DRM

    Merge branch 'buffer-objects'
    
    This branch changes i830_memory.c's allocator to use TTM when available to
    allocate memory, which also allows TTM to control almost the entire aperture.
    As a result, our front/back/depth buffers are created as real buffer objects,
    which may be used by the DRI driver instead of the fake buffer type in TTM.
    The updated DRM with bo_set_pin ioctl is required, to allow us to pin and
    unpin our buffers as needed.

    Only swap planes and pipes if DRM supports it
    
    We want to associate plane A with pipe B on pre-965 mobile chips, since that's
    the only way to get framebuffer compression on the builtin LVDS on those
    platforms.  However, if we do this swapping and DRM isn't aware of it, we may
    end up requesting vblank events for the wrong pipe, or setting up SAREA buffer
    swap state incorrectly.
    
    This mod checks whether DRM supports the new plane->pipe swapping behavior, and
    only enables the swapping if so.  This should fix the bugs Lukas found and
    debugged.  Reviewed by Michel Danzer.

    Tiling fixes for 965
    
    This should be close to the last set of tiling fixes for 965 chipsets.
    Prior to this commit, the 965 composite hook didn't take tiling into
    account, nor did 965 textured video, which caused display corruption.
    However, there seems to be at least one last bug to squash--on occasion,
    a configuration with tiling enabled won't properly display text.  This
    is likely another tiling related problem with the composite hook.

    Fix EXA rendering with tiled front buffer on pre-965.
    
    The 915 and earlier appear to respect the fence registers, while only the 965
    requires the per-operation tiling setting and pitch shifting.  This will also
    fix issues with rendering on the 965 involving multiple cliprects, where the
    pitch would get divided repeatedly.
    
    This removes the offset < 4096 fallback, which essentially resulted in no
    acceleration to tiled buffers, hiding the issues.

    Pin some buffer objects at creation time, which can't be moved yet.
    
    A number of other interfaces of ours don't allow buffer offsets to be updated
    after screeninit.  This attempts to catalog why for each one, so that they
    can be fixed one by one.
    
    This happens to restore the EXA offscreen allocator for now, as a fixed-offset
    object.

    Use new drmBOSetPin interface instead of NO_EVICT/NO_MOVE buffers.
    
    To do this, we have to deal with buffer offsets being set at EnterVT time
    instead of screen init time. We've wanted to move this direction for a long
    time, but there are repercussions.  The EXA offscreen memory manager has to
    be disabled, because it can't be moved.  That will be replaced by BO-backed
    pixmaps soon.  Also unresolved is whether our moving
    front/back/depth/texture buffers will break the classic-mode DRI driver.
    
    This code doesn't actually work yet.

    When TTM is available, use it instead of manual AGP allocations when possible.
    
    This is a step towards being able to expose buffer objects through the screen
    private to DRI clients, instead of having them have to use the fake buffer
    object type.
    
    This fails in two ways.  First, the kernel memory manager is not currently
    suitable for doing the physical allocations we need, so we still use AGP for
    those.  Additionally, the DRI lock can't be initialized early enough for us, so
    these buffer object allocations fail.  This will be fixed by improving the
    DRM interface.

    Remove hard-coded CRT blanking frobbing for load detection.
    
    CRT blanking needn't be adjusted to perform load detection on 9xx chips, and
    the 8xx load detection path now adjusts blanking just during load detection.
    Adjusting the blanking interval turned out to cause many monitors to fail to
    sync.

    Eliminate bogus (and harmful) blanking adjustment for load detect.
    
    Instead of always adding blanking to mode lines, use the FORCE_BORDER option
    on i9xx hardware where it works, and dynamically add a bit of border if
    necessary on i8xx hardware to make load detection work. This may cause
    flashing when a usable crtc is not otherwise idle when load detection is
    requested.

    The automatic panel scaling appears to choose bad sampling on some GM965

    if we just want 1:1.

    Fix load detection to use border region instead of blanking.
    
    Make sure there is some border area to use by changing how the pipe is
    configured, then pick a scanline in the middle of the border for load
    detection. This lets the load detect code use an active pipe instead of
    requiring an idle one.

    Increase vblank wait timeout from 20ms to 30ms. 49.6Hz < 20ms.
    
    The x40 LVDS mode has a 49.6Hz vertical refresh. Waiting for only 20ms can
    sometimes cause the driver to start programming the hardware before the
    vblank has occurred, which will lock up the i855 chipset. Extend this to
    30ms (the maximum timeout used by the BIOS) to ensure this doesn't happen.
    
    Detecting actual vblank occurance using the various status registers should
    also be possible but isn't yet working.

    The backlight control in the LVDS controller can either operate in 'normal'
    mode or 'legacy' mode. In legacy mode, it uses the PCI config space register
    0xf4 which can range from 0 to 0xff. In normal mode, it reads the range and
    current value from the BLC_PWM_CTL register.

    Now, all 3D pipeline consumers in the driver just call
    IntelEmitInvariantState(), which handles basic state setup, the caching of that

    wait in the Render code which was papering over the brokenness in the context
    switching.

    correctly clip to the bounds of the crtc, eliminating the need for any
    custom crtc clipping.
    
    Also, replace the broken xf86XVFillKeyHelper with a private version that
    doesn't end up stuck with the wrong clip list when the root window changes
    size.

    Ensure Pipe A is active when enabling overlay the first time.
    
    The overlay on the i830 appears to be clocked by Pipe A when being enabled.
    If pipe A is not running, it will freeze the overlay and blank the screen.
    Setting a random mode on the Pipe and turning it on fixes this problem
    nicely.

    No need to block for the overlay; just use the idle buffer.  This will
    always work because the buffer switch occurs at vblank time, so there is
    always plenty of time to get the next buffer contents in place before it
    starts getting scanned to the screen.

    Deal with i830 CRT load detection which cannot use FORCE_BORDER.
    
    Chips newer than the i830 can force the border color for the active period
    of the screen, allowing the load detection to easily see the right data. In
    addition, newer chips appear to have more sensible load detection hardware
    which either ignores inactive periods on the screen or performs some
    longer-term averaging. The i830 appears to provide unfiltered samples of the
    detected load.
    
    For the i830, then, emit a border at the bottom of the screen and, for load
    detection, simply turn it purple and wait for the current line to be within
    the border. Sample an entire scanline, counting the number of times the load
    detection sees a monitor. In my testing, the presence of a monitor will
    cause the detection to succeed every time, while the absense will cause it
    to fail about 75% of the time. The code here, checks for presence at least
    75% of the time, which should be adequate.
    
    Also, as the new mode configuration code has already taken care to enable
    the CRT output, eliminate much of the load detection code which is simply
    duplicating functionality from the general mode setting code. This should
    result in faster load detection as this code will now run in no more than
    one frame time. It does burn the CPU the whole time though, polling the
    displayed scanline register.

    Make up a fixed panel timing for DVO LVDS, and use DVOA for DVO LVDS.
    
    The fixed panel timing will only be available when the LVDS is already on
    at X startup.
    
    So far, our only mostly-working LVDS driver is for the i830, and on i830 the
    LVDS is always on DVOA, so use that for all LVDS chips.  This may need to
    change if we support the ch7017 I've seen used on embedded i845, for example.

    Allow physical-memory allocations within stolen memory.
    
    Because stolen memory happens to be a contiguous block of high system memory,
    we can just read the GTT entries for it to get physical addresses for our
    allocations there if needed.  This reduces fragmentation of the aperture space,
    and will often reclaim up to 7 MB of memory that had been left unused since the
    simplified aperture manager was put in place, but without reintroducing the
    complexities of the old aperture manager.

    Linux cannot allocate a large fixed buffer for the HW cursors as needed for

    allocate one buffer (less overhead) and falls back to separate buffers only
    when necessary.

    While we're just doing a memcpy, it's nice for the two argument types to

    Increase DDC I2C RiseFallTime to handle older monitors
    
    Changing this value slows the entire I2C bus down, making it far more
    reliable on older monitors. Note the same change has been made in the core X
    server code; this change is included here to ensure that older X servers
    work reliably with this driver.

    Fix crashes and other failures when a cursor allocation fails.
    
    Now, we allocate one single block of memory for cursors, and either succeed or
    fail once, rather than trying to support partial fallback modes that generally
    resulted in pain due to being untested.  In particular, this fixes cursors on
    FreeBSD, which only allowed one large physically-contiguous allocation.

    Make the depth buffer X tiled instead of Y, and fix a Y tiling nit on 945.
    
    The previous code claimed to set the depth buffer up as Y tiled, but due to
    lack of implementation in SetFence, it ended up being X tiled.  Actually
    setting the Y tiling flag in the new version broke the depth buffer, so just
    switch the depth buffer to X tiling, which appears to work fine.

    which memory manager to set up) to later.

    origin is always interpreted by the shadow copying code, the frame buffer
    itself doesn't move.

    Move EXA offscreen memory back after framebuffer to avoid fallbacks.
    
    Without this, the EXA code decides that the framebuffer is not in video
    memory because it's not located between the start of video memory and the end
    of EXA allocator memory.  We should either have EXA let the driver decide if a
    pointer is in video memory, or add a new field for "end of video memory" (not
    just end of EXA offscreen allocation), but this fixes things for now.

    Rework the video memory allocation.
    
    The previous allocator worked in multiple passes, with (at least) one of
    setting up allocations, another to attempt to adjust those for tiling, and
    then a pass to set up the offsets and fix them in memory.
    
    The new allocator is simpler, allocating memory immediately if possible,
    setting up tiling up front, and choosing offsets immediately.  AGP memory
    is only allocated to back actual memory used, saving some memory that would
    have been allocated for padding previous. It will also allow dynamic freeing
    and reallocation of memory, which will be useful for framebuffer resizing.

    Pre-965 hardware had fixed pipe 1 for panel fitter.
    
    The pipe mode setting code needs to disable the panel fitter when using the
    pipe for things other than LVDS output. The driver was checking for panel
    fitter conflicts using bits that the 965 chipset defines for selecting which
    pipe the panel fitter is connected to. However, on pre-965 hardware, the
    panel fitter works only with pipe 1 and those bits returned 0.
    
    The result was that when pipe 1 was using the panel fitter, configuring pipe
    0 would disable the panel fitter.
    
    The fix provided uses a model-specific test for the panel fitter pipe.

    This adds reasonably driver-independent rotation support to the common

    rotation operation (which leaves us free to do fun projective transforms at

    Our modes typically come from EDID or default modes, and when the monitor
    asks for a specific mode, deciding to tweak it usually results in incorrect
    display.  And if the user is specifying a mode by hand, tweaking it then is
    still pretty rude.

    data and causing the hardware to lock up. (along with generating a garbage
    cursor image from uninitialized data).

    Don't zero out mode structure after setting name field.
    
    Instead of using memset to zero the structure (at the wrong time, no less),
    use xcalloc to gather pre-initialized memory.

    Mark crtc region as damaged when rotation is set.
    
    When shadow frame buffer is allocated for rotation, it needs to be
    initialized by copying from the frame buffer. Do this by simply marking the
    entire screen as damaged which will force an update.

    Make rotated pixmap size of mode, not rotated mode. Update only damage.
    
    Rotated pixmap should match size of displayed mode, not the rotated version
    of that size.
    
    Take damaged region, rotate each box and display them instead of displaying
    the whole screen after each damage update. This exposes a bug where the
    screen is not correctly damaged after rotation.

    Bug #8845: Unify all our XV ports to 1920x1088 maximum size.
    
    This increases the "legacy" size, but that was checked against the 845
    documentation which claims support for 2048x2048 as well.  It decreases the
    textured video size, which was running into the limits of the bigrequests
    extension.  The new limits should fit within bigrequests while still supporting
    HD videos.

    Don't limit cachelines to a vertical of 2048, and increase default allocation.
    
    The cachelines are used for two things: XAA pixmap cache and XV memory.
    Only XAA pixmap cache is referred to using an offset pointing at the
    beginning of the front buffer in rendering, and XAA only uses the 2d BLT
    engine, which actually has a vertical limit of 65536.  So, pixmap cache is now
    limited to that much vertical.
    
    Additionally, the previous cachelines allocation was too small for our
    advertised XV limits, so video at the limits would fail with BadAlloc.  Now,
    XAA allocates the same approximate amount of offscreen memory as EXA:
    3 times the screen size, plus one packed HD video.

    Correct x/y/pitch limitations in several cases, and detail them in i830_exa.c.
    
    This reduces max framebuffer width and increases max framebuffer height on
    965, reduces max X/Y on pre-965 EXA (could have caused mis-rendering), and
    increases max X/Y on 965 EXA (would have prevented acceleration).

    Detect in ProbeModes. Let get_modes set edid. Prune interlace/dblscan.
    
    Move output connection status detection from RandR code up to ProbeModes so
    it is done before mode sets are built. Otherwise, the mode building code
    will elide all modes the first time through as it ignores outputs that are
    disconnected.
    
    Most get_modes functions fetch EDID data; make sure that any
    EDID changes are used in the ProbeModes filtering of default modes.
    Otherwise, stale EDID data will be used.
    
    Allow outputs to advertise support for interlaced and double scan modes;
    prune such modes from the default mode list when outputs do not support them.

    Remove 8MB/32MB default VideoRam limits.
    
    With modern monitors and increased XV and EXA memory requirements, these small
    limits were resulting in DRI and other initialization failures because we
    wouldn't allow them enough memory.  Instead, allow each piece of the system
    (DRI, EXA, XAA, etc) to request as much memory as it wants, and choose the
    actual videoRam to be used for laying out the memory afterwards.
    
    With this change, in the absence of a VideoRam option, 32MB will be allocated
    for textures.

    Move dvo driver detection into i830_dvo_init(), and use GPIOB for LVDS drivers.
    
    The documentation states that GPIOB is (generally) used for devices on DVOA
    on the motherboard, which appears to be the case on the laptop we have with
    LVDS on the motherboard.
    
    This patch is probably not entirely accurate, as there was apparently an LVDS
    DVO card sold that could be put in desktop machines, which would likely be on
    GPIOE like other ADD cards.  Given that we couldn't find one of these cards for
    purchase, I'm not worrying about it.

    Bug #7524: Major improvements to EXA/XAA static memory allocation.
    
    With this, we no longer allocate XV through the XF86 linear allocator in the
    EXA case.  We also no longer allocate extra space for the XF86 2D allocator
    that we don't use in EXA mode, or space for the EXA allocator in XAA mode.
    The EXA offscreen allocator now gets enough space for several screenfuls of
    pixmaps plus one 1920x1088 movie.
    
    A large duplicated section of code for allocating each framebuffer in the old
    dual-screen mode was also factored out.

    TV subcarrier was computed from wrong clock value.
    
    The constants provided in the documentation for the subcarrier DDA values
    assumed the clock was programmed to precisely 108MHz, but the PLL can't hit
    that value exactly (or our PLL computation can't, in any case). The
    result was an incorrect subcarrier frequency which resulted in synthetic
    subcarrier phase shift and a lovely rainbow effect on the screen.
    
    Unfortunately, the documentation didn't exactly describe the function
    performed by the subcarrier clock hardware, so a bit of detective work was
    needed. New constants were computed using the code in tv.5c and those, along
    with lots of other values from the documentation were inserted into the
    necessary tables.
    
    The result appears to generate stable NTSC video on the svideo connector.

    Bug #8786: Treat pictures with no color data as non-component alpha.
    
    This is an un(der?)-documented part of the render protocol: If the mask is
    alpha only, then the component alpha flag is ignored on it.

    Prefer earliest CRTC when mapping to outputs.
    
    For some reason, the code was preferring the last possible output when
    mapping outputs to crtcs. Use the earlier CRTC instead to make the i830
    driver consistent with BIOS usage.

    Not restoring active outputs. Wait for input sync before enabling outputs.
    
    Oops--looks like a typo to me; the code was callint set_target_output
    instead of set_active_outputs.
    
    BIOS loops waiting for the SDVO input to sync before enabling outputs, this
    makes sense to me.

    Instead of delaying pll/pipe/plane enables to the dpms function, turn them
    on right away in the crtc_set_mode function. To avoid rewriting these
    registers in the subsequent dpms function, check each register written there
    to see if the enable bit is already on and don't rewrite.

    computation (and, eventually, the config-file based configuration as well).

    DOUBLE_WIDE mode for high pixel clock 8xx. Rewrite PLL search.
    
    High pixel clock modes on pipe A of an 8xx chip require
    DOUBLE_WIDE mode. It's supposed to be modes > 180MHz or so,
    but the board I have requires DOUBLE_WIDE mode for clocks > 108MHz
    or so. The limit is related to the core clock speed of the chip, which
    can be found indirectly through PCI config space. None of the possible
    values explain why this board needs this mode for these relatively low
    clock rates though.
    
    Also, create tables of data for the PLL computation and use them
    instead of code. I think it's cleaner looking. It is also untested on
    9xx. It'll work. Really.

    Yes, this means not detecting TV hotplug when two outputs are
    already running. An alternative would be to turn off one of the other
    outputs temporarily, but that would cause flashing. Something to consider.

    Tristate the clock/data pins during GPIO when released while getting values.
    
    While the register is laid out suggesting that you can read a low value while
    driving the output high, and the I2C spec seems to indicate that you should be
    able to as well, and on some hardware this works successfully, on the i865 and
    perhaps some other chips it doesn't.  So, if we're not holding the clock or
    data pin low during GetBits, tristate the pin so that we can successfully read.
    
    This fixes i865 analog (VGA) DDC so it successfully sees slave acks.
    
    Also, improve the I2C bit-banging debugging.

    Properly detect the GTT size on the G965.
    
    In the past, the GTT has always been sized just large enough to map the whole
    graphics aperture.  However, apparently on the G965 that isn't the case, and
    it is actually 512KB on hardware with a 256MB aperture.  This resulted in X
    not bothering to allocate memory for 256KB that it thought was already mapped
    into stolen memory, and thus garbage rendering (particularly visible in large
    video modes that displayed this unallocated memory).  The kernel happens to
    get the right answer by hardwiring a 512KB GTT size already, but that may not
    be true on future hardware.
    
    Instead, we use a convenient field in PGETBL_CTL that's specifically for the
    GTT size rather than the aperture size, which gets us the answer we want.

    The GTT is definitely located at the end of stolen memory.  This commit
    apparently worked around mis-estimation of the GTT size.

    Clean up reworked data structure code so the server actually starts.
    
    Use i830GeLoadDetectPipe again (instead of missing xf86AllocCrtc).  Actually
    create new Crtc structures. Fix a few other NULL pointer dereferences.

    Start output/crtc restructuring work. It compiles.
    
    Outputs and Crtcs are now split between 'generic'
    and 'driver specific' pieces in the hope that more code
    will be able to migrate to the xf86-generic layer.
    
    Right now, the code remains tangled together, significant
    work remains to tease the pieces apart. First the code
    needs to be made to actually work as-is though.

    3D rendering pipeline is limited to pitch of 8Kbytes and not 4096

    Either some preferred size or a size which yields 96dpi is chosen,
    from which other monitors are set to a similar size. The largest
    size sets the screen size.
    
    This needs to be extended to respect config file settings, but
    those have not been defined yet.

    I830 contained six parallel arrays for pipe-specific data; these
    have been moved to a I830PipeRec structure instead.
    
    I830 also contained several unused members:
    
       unsigned int bios_version;
       Bool newPipeSwitch;
       Bool fakeSwitch;
       int fixedPipe;
    
    These have been removed, along with the code that set them.

    Disable the panel fitter when not using it. Cleans up SDVO DVI output.
    
    The panel fitter appears to exist on the 965 hardware (at least) and
    causes troubles with DVI output over SDVO when enabled. This patch
    checks to see if the panel fitter is pointing at the pipe being configured
    and disables it unconditionally in that case. The LVDS driver will configure
    it correctly if necessary afterwards.

    Move mode lists from per-pipe to per-output.
    
    This should let RandR do the right thing in exposing the modes to userland.
    
    As a side effect of getting this working, the SDVO pixel clock range code
    was fixed and the mode valid tests for various outputs got extended.  Also,
    LVDS grew a get_modes for the fixed panel mode.
    
    Note that we now no longer do automatic enabling of outputs at xrandr -s 0,
    hotkey, or VT switch.  That will be left to generic RandR code later.  Also,
    generic modes and user-defined modes are once again not validated into the
    lists, so this is a regression there.

    The get_modes should return the probed modes only.  The driver should then

    or standard VESA modes) to create the list to expose through RandR.  That
    isn't done yet.

    Major cleanup of 3D invariant state, fixing hangs with rotation and render.
    
    Now, the generic invariant state is always set while the X Server is active,
    and happens automatically when the X Server grabs the DRI lock.  More 3D state
    is moved to the generic code.
    
    Then, the 3D consumers (video, rotation, render) set last_3d to their enum
    entry, and can update their own invariant state when another consumer was
    active.

    userland policy with RandR 1.2 or RandR 1.2 XFree86-DDX generic code.

    Clean up the SDVO code.
    
    The main change is to send SDVO commands using data passed into the send
    command function, and receive responses into memory passed into the read
    response function, rather than stuff things in/out through dev_priv->sdvo_regs.
    This lets us use structures to represent some arguments, which results in a
    nice cleanup (and 100% fewer arguments named magicN as a side effect).
    
    Also, the mode set path is changed to not do any preferred input timing
    work.  We weren't doing anything legitimate with the results, since we didn't
    modify the CRTC timing appropriately, so now we just stuff the CRTC timing into
    both and hope for the best.  This should probably be revisited later.

    Clean up SDVO code, moving the private structure internal and cleaning up caps.
    
    All the SDVO code should now be in lower case rather than StudlyCaps.
    
    This also adjusts the I2C setup to create a bus per SDVO output we set up.
    The previous setup with shared buses was failing in some circumstances, which
    is probably due to the lack of refcounting in xf86i2c.c.

    the DPLL registers.  When possible, the DPLLs are just adjusted in the
    per-output post_set_mode, which happens just after the DPLL is enabled.
    However, this seems better than the previous method of having all outputs
    programmed in the same function.

    Attempt to make the ACPI hotkey support a little more modesetting-compatible.
    
    Previously, we watched for the BIOS to have changed the layout, and repaired
    the resulting configuration.  Now, we request that the BIOS make no changes,
    but leave a note in a register for when the key has been pressed.  When we
    notice this, we reprobe monitors and turn on/off the things we find.
    
    This is a temporary solution until we can get the hotkey hooked up as an
    input key to external applications to control the change using RandR 1.2.  It
    is also untested as neither of my laptops do anything with the hotkey.
    However, this code does result in many fewer BIOS calls.

    When detecting a monitor that doesn't support DDC, construct a default

    	Can't move outputs on/off crtcs
    
    But, it does handle monitor hot-plug, detecting changes in VGA and SDVO
    status on-the fly. Which makes for good demo material.

    If CA is set and blend op needs src alpha, the src
    value is not needed and should be (src.A * mask.X).
    This is found in handling exa magic two pass composite.

    Add model-specific tweaks for some funky 945GM boards.
    
    For the Aopen Mini-PC, ignore the claimed attached 800x600 LVDS panel.
    Likewise for the Apple Mac Mini, but done slightly differently since it
    shares PCI IDs with the Macbook Pro.

    Add a compile flag to enable syncing after each operation in EXA.

    doesn't change the mis-rendering of text on the 915.

    Add a check for intel-gen4asm, and rules to compile {wm,sf}_prog.h using it.
    
    This adds assembly source for the two programs used in the textured video
    implementation on the 965, which should make them easier to modify in the
    future. The compiled versions are also included, so that intel-gen4asm isn't a
    build requirement for people that aren't modifying these programs.
    
    There are minor differences in the compiled versions of these programs compared
    to their previous versions which were compiled with a different tool.  I
    believe the changes should be harmless, and video continues to work on my
    system.

    The driver now reports itself as the PACKAGE_VERSION from autoconf.  The DRI

    appropriate major/minor versioning of the interface that's not tied to the
    package version.  Bumped the i830 ddx dri version patchlevel to note the
    fix in the previous commit.

    Disable dynamic front buffer mapping on i965.
    
    Moving front buffers should only be necessary for rotation.  Currently, the

    harmless for now.

    Make the sampler's payload be the WM payload rather than uninitialized data.
    
    The sampler's payload happens to be in the same format as the WM payload,
    though most of the fields are ignored.
    
    This appears to fix the program in the presence of multiple PS threads.

    We don't know what COLOR_BUF_8BIT does, so it's disabled for now while we're
    stabilizing the code.
    
    The non-extended repeats appear to be working according to the rendercheck
    tests on a8 and a8r8g8b8 sources.  Masks continue to hang the card, as before
    this change.

    Try to fix up the basic RepeatNormal and RepeatNone support.
    
    With RepeatNone, access outside of the drawable should return 0 alpha values,
    which is done by using the border color.  For RepeatNormal, we use the wrap
    mode (which requires that we use normalized texture coordinates).

    Convert magic numbers to symbolic names in i915 rotate code.
    
    This doesn't cover the fragment shader yet, which we need to make a sensible
    set of macros for (at least the basic bits).

    Disable spread spectrum clock usage.
    
    The spread spectrum clock generator that improves EMI characteristics for
    laptop screens lives in an external chip that is programmed over an i2c bus.
    Without correct programming, attempts to use this mode for the LVDS can
    result in a DC signal being sent to the panel.
    
    Until we find programming information for this external chip, we should
    leave this mode disabled.

    This fixes a hang on the i945 during restore.  It appears that saving/restoring

    registers we touch within the driver anyway.

    Bug #7443: Respect the user's Modes configuration, and make it more useful.
    
    Now, mode names generated by DDC get names of the form "WIDTHxHEIGHTxREFRESH".
    The matching for user Modes lines takes the user Modes as the prefix that
    needs to match, rather than an exact string match or "WIDTHxHEIGHT" match.  So
    one can, for example, specify "1024x768" to get any old 1024x768, or
    1024x768x60 to get one of the modes named 1024x768x60.

    Replace xf86ValidateModes usage with a set of custom validators and pruning.
    
    This moves us to maintaining MonPtrs per pipe instead of using the EDID
    structure "xf86MonPtr", which is closer to what we want to be looking at when
    doing validation.  The new validation isn't enough yet -- particularly, we
    aren't importing and validating the custom modelines to the pipes when
    applicable, but this will be easier than (for example) trying to make flat
    panel modes pass xf86ValidateModes through various gross hacks.
    
    Hotplug turn-on/off also happens at SwitchMode time now, instead of at randr
    probe time.

    Major cleanup of mode reprobing:
    - Don't mess with pScrn->monitor->Modes, and instead make our own availModes.
    - Don't re-program the pipe with the same values (no flicker at xrandr)
    - Move a bunch of stuff that should be exposed through the public API (probably)
      to i830_xf86Modes.c
    - Use a table with established modes plus GTF to come up with modes from EDID,
      instead of trying to walk and find one in pScrn->monitor->Modes.  I think
      this is correct.
    - Reset clone state if we've detected new pipes, which should turn on the
      cursor.

    WIP to allow re-probing and validation of modes for new heads at "xrandr" time.
    
    Now, DDC modes always end up being preferred to custom modelines, even if
    smaller.  This should probably be fixed by inserting custom modelines into
    the probed mode list if they're valid according to the probed parameters of the
    monitor.
    
    Too much code is lifted from static functions in xf86Mode.c, and those should be
    made unstatic if possible.  Using xf86ValidateModes is also rather hacky, and
    I want to break the function down, but this is a first step.

    Split probed modes out per pipe, and union them into the available modes.
    
    This is the first stage of getting runtime monitor attachment.  The old i830
    GTF code is returned to use to provide suitable modelines for xf86ValidateModes
    in the LVDS case, even though the LVDS doesn't care about the modeline and just
    always programs its fixed values.

    Fix SDVO output at low pixel clocks.
    
    I had interpreted the docs as saying that the multiplier setting would further
    divide the clock and stuff dummy bytes in.  Instead, we have to set the DPLL at
    the higher clock rate, and the pixel multiplier just controls the stuffing of
    dummy bytes.  Also, we have to set the multiplier both in the graphics chip and
    on the SDVO device on the other side.

    Only default to enabling CRT or LVDS output if they're actually detected.
    
    Still, if we haven't detected any outputs automatically (including CRT through
    DDC), default to CRT anyway.

Date:   Tue Jun 20 14:32:40 2006 -0700

    Add support for CRT detection using DDC.
    
    This method is slower (~5ms), but works on older chipsets.  Also, load-based
    detection is disabled, as it can be fooled by other outputs on the pipe being
    active, such as LVDS.

    Set vblank interrupt configuration to match pipe configuration
    
    New i915 drm ioctl (in version 1.5) allows the X server to select
    which pipe drives vblank interrupts. Use this to drive from the 'preferred'
    pipe. Yes, per-window vblanks would be nice in a shared fb environment.
    Maybe someday.

    Commit a WIP implementation of the planar video shader that does the
    
    planar-to-packed conversion for us.  Unfortunately the documentation is unclear,
    and I haven't managed to get any implementation of it working correctly.

    Add initial textured XV support for i915, which can do YUY2 and UYVY, but fails
    
    on I420 and YV12 currently, doesn't support the composite extension, and should
    break XV support on non-i915.

    Start trying to implement DDC over SDVO.  It's slightly tricky because the
    control bus will reset from DDC mode to internal-registers mode after every
    Stop afer a Start on the DDC bus.  The xf86 DDC code causes multiple Start/Stops
    in one probe.  So, we create a wrapper bus that does the control bus switch at
    every Start.  It's not working yet on my hardware, but I'm pretty sure this is
    the right way to go.

    Remove the int10 POST on EnterVT.  It has been reported to cause crashes now,
    and I believe it is the responsibility of the kernel to bring the device back to
    a mostly-sane state on resume anyway.

    Don't try to use LVDS by default on chipsets that won't have an LVDS attached.
    The BIOS tables may still exist, so we can't rely on their presence to indicate
    LVDS attachment.

Author: Eric Anholt <anholt@FreeBSD.org>

    Remove the hacky-looking Set640x480. I'll be removing things it depends on
    (setpipe), and I suspect we'll end up with different hacks for resume, anyway.

Author: Eric Anholt <anholt@FreeBSD.org>
Date:   Mon Apr 3 15:28:47 2006 -0700

    Remove more BIOS stuff, particularly Get/SetDisplayDevices. Now, if there's no
    hardcoding in the config file, we default to LFP if we detect it from BIOS, and
    LFP or CRT if we can get EDID out of them.

    save/restore everything it knows about.  Also moves the save to just after the
    other reg saves, above the VBE save stuff which may have side effects.

    Move the PFIT enabling before the enabling of the pipe, as the specs say we
    should.  This doesn't work yet, as we apparently need to adjust the pipe to
    output at the full resolution of the panel, not the displayed image size,
    because PFIT controls scaling between the display planes and the pipe.

    Replace I830VESASetMode with simpler i830SetMode, which is all native and
    doesn't have BIOS-setup workarounds.  Multihead behavior may be wrong, and it is
    all untested.

    Disable I830VESASetVBEMode on restore, since I've removed that code. Note that
    this means that VT switching is broken.  We're fine with that for now, but at
    least now we get a bad display rather than X crashing about an undefined symbol.

    I have resolved this by making all the "Direct rendering disabled" messages
    X_WARNING and all the "Direct rendering enabled" messages X_INFO.  Ideally,
    we need to factor some of this stuff out to common code.  There is a *LOT* of
    duplication among the *_dri.c files under programs/Xserver/hw/xfree86/drivers.
    
    I'm trying to clean up as much low hanging fruit as I can and got tired of

    Bug #3163: Create new DRIINFO_*_VERSION macros to indicate the
    version number of the DRIInfoRec, disambiguating it from the XF86DRI
    protocol version number.  Modify DRIQueryVersion to return the libdri
    version number, which all DDXes were requesting implicitly.  Fix the
    DDXes to check for the DRIINFO version they were compiled against.

    Fix includes right throughout the Xserver tree:
      * change "foo.h" to <X11/foo.h> for core headers, e.g. X.h, Xpoll.h;
      * change "foo.h", "extensions/foo.h" and "X11/foo.h" to
        <X11/extensions/foo.h> for extension headers, e.g. Xv.h;
      * change "foo.[ch]" to <X11/Xtrans/foo.[ch]> for Xtrans files.

    Enforce DDC monitor ranges usage if we have them and reject bad
    modes. Use NoDDC option to override DDC timings. We currently
    only use DS_RANGES, but could use other DDC information, as does
    the common layer, to deduce the h/v ranges.

    Check return value of i830InitDma() and fail to initialize the DRI
    if that fails.
    Also, check the DRM module name that it matches i915 and not the
    older i830 driver which some people were still trying to use
    and was causing Dma Initialization failures and lockups.

    Bug #400 (partial): Driver fixes for the dlloader.  When using
    dlloader, all framebuffer formats except cfb and the overlay modes
    should work, and r128 and radeon need to be loaded from the ati
    driver (both issues to be fixed soon).  Tested on i740, s3virge,
    mach64, tdfx, vesa, and vga drivers.  elfloader users shouldn't be
    affected.

    Increase default video RAM size to 16MB when DRI is enabled and more than 128MB
    are available (Egbert Eich).
    Fixed lockups during mode switch. Problem was introduced when attempting to copy
    the behavior during LeaveVT()/EnterVT() but but forgetting to call
    I810DRILeave() before I810DRIEnter(). The entire DRILeave()/Enter() scenario has
    been commented out as it didn't seem to be necessary (Egbert Eich).
    Fix TweakMemorySize() (tested with i855/i865) (Egbert Eich).

    Merge DRI-trunk-20040613 changes in programs/Xserver/hw/xfree86/drivers, with
    the following notes:
    
    - Savage and Mach64 (= ati/ati*.[ch] changes) DRI not merged due to insecurity.
    - VIA driver converted to new drmContext and drmHandle names.
    - Radeon driver merge conflicted in many places, and MergedFB at least could
      probably use some checking at this point.
