Booting FreeBSD on Ampere's Awesome Altra CPUs

Friday, 2 Jul 2021 Tags: amperefreebsdoci

This is a series of posts exploring how we can get FreeBSD to boot up in Oracle Cloud Infrastructure OCI, which is the commercially available source of the 160-core dual socket Altra CPUs from Ampere.

Geek Envy

Yes, 160 cores on a single system. These are not your scabby x86 Symmetric Hyperthreading cores, each one is a fully capable 3.3GHz behemoth. Here are the specs from the initial Altra announcement:

Altra® Multi Core Server Processors

Ampere server processors are a complete system on chip (SOC) solution built for Cloud Native server applications. The device supports up to 128 Arm 64 bit cores, 8 Channels of DDR4 and 128 Channels of PCIe Gen 4 interfaces.

  • Up to 128 cloud optimized 64 bit Armv8.2 cores
  • Up to 3.3GHz frequency of operation
  • 8×72 bit DDR4 3200, ECC Support, 4TB Capacity
  • 128 PCIe Gen4 lanes
  • Coherent multi socket support
  • I/O and Interrupt Virtualization
  • Enterprise server class RAS

There is some performance propaganda available too.

Support

The arm64 platform has had tier 1 support since FreeBSD 13.0-RELEASE, and I have been running it very happily on the “small” eMAG systems from Ampere for many months. When I say “small” it only has 32 cores, runs at a leisurely 3.0GHz and my install only has a single PCIe4 NVMe drive, with just 256GiB RAM… so only small in comparison to its newer, bigger twin brothers!

We’ve had access to the newer Altra system hardware already, and the functionality is identical.

The performance is excellent, all the nice FreeBSD bits like ZFS, jails, and firewalls just work, as you’d expect. Some functionality (full IPMI, various sensors, including cpu frequency & temperature sysctls), are not yet exposed but all the important stuff - networking, storage, remote console, is fantastic. Of particular note is that the NICs support HTTP boot, as well as full remote console (mounting images etc), so once you’ve physically plugged the box in, you’ll rarely need to go to it.

ipxe also works, so a simple recovery solution is to configure the UEFI firmware to load ipxe over the network, and from there to pull in the FreeBSD loader via HTTP boot.

OCI

Oracle has production Altra systems available, both as para-virtualised cloud VMs, and also as bare metal behemoths. There’s a bunch of propaganda docs with some useful general info:

We are interested in 2 things:

  • boot FreeBSD on PV mode
  • boot FreeBSD in BM mode

Hijacking Linux, aka de-penguinification

As a starting point, I tried “de-penguinating” an existing Linux instance. This was easy: drop loader.efi into the EFI partition, dd(1) the FreeBSD installer on top of the Linux swap partition, and reboot. But, on reboot, the EFI partition mysteriously returned to Oracle defaults. I am not sure if this is a loader issue, or an OCI feature.

I re-tried with refind, also no luck.

Bring Your Own Images

My second attempt was to upload various FreeBSD release installers into OCI Cloud Storage, then create new Bring-Your-Own bootable images from those uploaded files, and try to boot off those.

$ qemu-img convert -f raw -O qcow2 \
    FreeBSD-13.0-RELEASE-arm64-aarch64-memstick.img \
    FreeBSD-13.0-RELEASE-arm64-aarch64-memstick.qcow2

I also realised in hindsight that FreeBSD provides both vmdk and raw ready-to-roll images, but I did not get as far with those.

This process is a little muddly, I will update this post in future on exactly how to go about that. In a nutshell, qemu-img convert your desired setup, upload it into blob storage, create a new “cloud image”, tweak the supported shapes to only A1.Flex and A1.BM types (Para-virtualised and Bare Metal respectively), and guess randomly the bewildering array of options you’re presented with. I would hope that Native eventually works, but it’s not entirely clear what underlying hardware this actually is. I expect it’s some sort of KVM / QEMU combined with iSCSI for storage, and VFIO for networking.

When you create the image, you need to define its capabilities, and compatible shapes:

  • BM.Standard.A1.160
  • VM.Standard.A1.Flex
  • firmware: uefi_64
  • launch mode: emulated
  • nic attachment type: paravirtualised
  • boot: paravirtualised
  • boot volume type: paravirtualised
  • local data volume: paravirtualised
  • remote data volume: paravirtualised
  • paravirtualisation version: 2 (using v1 also fails)

I tried creating a native image type, which got quite a bit further. Unfortunately it’s not clear what the image source was, but I think it’s my qemu-img converted raw FreeBSD installer.

Image:                                  freebsd-13.0-arm64-native
Launch Mode:                            EMULATED

Local Disk:                             Block Storage Only
NIC Attachment Type:                    PARAVIRTUALIZED
Remote Data Volume:                     PARAVIRTUALIZED
Firmware:                               UEFI_64
Boot Volume Type:                       PARAVIRTUALIZED

After the instance has been created, add a console connection which is just a bunch of ssh wrapping whatever KVM provides us over serial port, and then force restart the instance, (its dead at this point anyway) and see the console garbage fly past.

$ ssh -o ProxyCommand='ssh -W %h:%p -p 443 ocid1.@oci.oraclecloud.com' \
ocid1.instance.oc1.eu-amsterdam-1....

I could get to the loader prompt, as far as the infamous error 19:

mountroot: waiting for device /dev/ufs/FreeBSD_Install...
Mounting from ufs:/dev/ufs/FreeBSD_Install failed with error 19.

This presumably fail without appropriate iSCSI or similar drivers already available to the loader itself. This may require building a custom FreeBSD kernel with the drivers already embedded into loader.efi, if that’s even possible.

The full dmesg, as far as we get, follows:

At this point, I fiddled with the loader, but made no progress. Whatever image we boot from, I can’t get past this point. Maybe the info below helps somebody else.

Type '?' for a list of commands, 'help' for more detailed help.

Terraform Stacks

When you do the manual A1.Flex launch, you’ll notice an option to save the stack. If you do this, you can download a zip file, which contains a terraform provisioning script.

This encapsulates the usual network and image settings, so yours won’t be the same as mine, here’s what I have:

provider "oci" {}

resource "oci_core_instance" "generated_oci_core_instance" {
    agent_config {
        is_management_disabled = "true"
        is_monitoring_disabled = "true"
        plugins_config {
            desired_state = "DISABLED"
            name = "Compute Instance Monitoring"
        }
    }
    availability_config {
        recovery_action = "RESTORE_INSTANCE"
    }
    availability_domain = "Ynwz:eu-amsterdam-1-AD-1"
    compartment_id = "ocid1.tenancy.oc1..blah"
    create_vnic_details {
        assign_private_dns_record = "true"
        assign_public_ip = "true"
        subnet_id = "ocid1.subnet.oc1.eu-amsterdam-1.blah"
    }
    display_name = "beastie"
    instance_options {
        are_legacy_imds_endpoints_disabled = "false"
    }
    metadata = {
        "ssh_authorized_keys" = "ssh-ed25519 AAAAC3Nzblah"
    }
    shape = "VM.Standard.A1.Flex"
    shape_config {
        memory_in_gbs = "24"
        ocpus = "4"
    }
    source_details {
        source_id = "ocid1.image.oc1.eu-amsterdam-blah"
        source_type = "image"
    }
}

Setting up terraform on FreeBSD is extraordinarily easy compared to ports. Run this in the same folder as your unzipped main.tf config.

I skimmed this OCI Terraform tutorial and managed to get far enough along to automate spinning up systems. This is an excellent approach.

$ sudo pkg install -yr FreeBSD \
    sysutils/tflint \
    sysutils/terragrunt \
    sysutils/terraform \
    sysutils/terraform-docs
...

$ terraform init

Initializing the backend...

Initializing provider plugins...
- Finding latest version of hashicorp/oci...
- Installing hashicorp/oci v4.33.0...
- Installed hashicorp/oci v4.33.0 (signed by HashiCorp)

Terraform has created a lock file .terraform.lock.hcl to record the provider
selections it made above. Include this file in your version control repository
so that Terraform can guarantee to make the same selections by default when
you run "terraform init" in the future.

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.

$ terraform apply

Terraform used the selected providers to generate the following
execution plan. Resource actions are indicated with the following
symbols:
  + create

Terraform will perform the following actions:

  # oci_core_instance.generated_oci_core_instance will be created

Apply complete! Resources: 1 added, 0 changed, 0 destroyed.

Once the terraforming is complete, go to your OCI console, find the image, and create a Console Connection again as before.

Things I Want To Try

I’d like to get ipxe booting directly. This is mainly because uploading an image each to OCI is slow and painful.

Also, understanding why the loader bails with error 19 and addressing that would be even better.
