Intel Arc on Ampere Altra (unstable but somewhat working)

General Discussion
1

I think it is better to have a separate thread about all the effort to get it working.

For historical context: ASRock Rack Ampere bundle - #40 by Civiloid and below are the original messages.

Current status:
Modesetting: works after a patch
DRM: Hangs on start

HW I have:
GPU: Intel Arc 750
MB: Asrock ALTRAD8UD-1L2T
CPU: Altra Q64-22

Kernel: latest (6.9-git from master from ~5th of May, will update it at some point)

What has been done:
First note - card barely fits because it is large. It doesn’t fit into last two slots because they are too close to the battery. See photos in the original thread: ASRock Rack Ampere bundle - #44 by Civiloid

Attempt to just compile Xe kernel module and start gdm - compiles just fine, module OOPSes on load with:

Note: module reuiqres xe.force_probe='56a1 option on cmdline or equivalent on modprobe.

Patch to fix that: linux-xe-aarch64-v0.patch · GitHub

After that module loads and I gnome running in software mode and outputing via Xe.

That makes modestetting - working.

Attempting to get 3D Acceleration to work:

  1. On debian, libdrm doesn’t build libdrm_intel on non-x86, that is simple to fix: libdrm-2.4.120-debian-intel-aarch.patch · GitHub
  2. For mesa, I took 24.1.0-rc3 as there was a lot of work around support of Xe kernel module, but few things in just a build system was required: mesa-24.1.0-rc3-allow-i915-to-compile-on-aarch64.patch

That compiles mesa just fine. Then the problem starts.

I’m getting initial image with a cursor, however gdm hangs immediately, consuming 100% CPU in a busy loop.

And after that it is basically stuck. I guess no surprise if something times out and then it suggested to get a coredump (though sysfs path is wrong).

And full log: gist:bee72c168ecc319b8eef89eb12b3db9e · GitHub

But that is on a kernel without PCIe patch, so maybe that is the reason why card is stuck. I’ll verify that.

UPD: And no signicant change if I re-apply the patch. I think I’ve managed to better isolate messages around the problem:

Currently I’m stuck here as I don’t know the reason why the card hangs.

@bexcran tagging you just bc it might be relevant to your A310 too

So, I’ve compiled a kernel from drm / xe / xe kernel driver · GitLab with Altra’s PCIe Errata patch applied and with my patch to make it not-OOPS, and with mesa and libdrm patches I’ve mentioned I can actually run doom3 there (though sometimes it locks up, but I don’t know is it because of the Xe driver state or not)

It is slow (probably because I still have debug drm flags enabled), but it works.

When I’ve tried to run Quake 2 RTX, I got a kernel panic:

It was showing picture but extremely slow.

Also so far I see a pattern: on a first run on GDB it locks up when I try to enter password, then if I restart gdm (over ssh for example) it allows me to login and OpenGL seems to be working to some extent (doom3 was running idle for 30 minutes without any issues)

At some point I managed to get an OOPS instead of panic:

Actually reproduction there is somewhat easy - you need to build and run GitHub - GPSnoopy/RayTracingInVulkan: Implementation of Peter Shirley's Ray Tracing In One Weekend book using Vulkan and NVIDIA's RTX extension.

@Civiloid May you try transcoding a video file?

@Civiloid did you not run into this?

Yes, I did. I’ve ported those patches to 6.9.0 myself. I haven’t tried 6.10-rc1 though as I in general try to avoid kernels up until at least rc3 with very few exceptions.

The whole diff (I haven’t maintained proper split on commit-level and also mixed in my patch for Xe driver): altera-6.9.0.patch · GitHub

For 6.9.0 the change is relatively simple:

  1. You need to have ARM64_PA_BITS_52 in a kernel, so ALTRA_ERRATUM_82288 must depend on that (therefore added select ARM64_PA_BITS_52 in KConfig)
  2. The bitmask was renamed to PHYS_TO_PTE_ADDR_MASK (was PTE_ADDR_MASK)

P.S. I’ve also commented on github issue.

Thanks @Civiloid . You mentioned in your blog that some distro’s are already including these patches in their binary kernels. Which distro’s would that be?

Given the fact that these patches come with a performance penalty, it would surprise me if they are built and activated in binary kernels. They would slow down all ARM architectures, and might unnecessary slow down Ampere servers that do not require GPU’s. I would think that activation would need to be triggered by a kernel command line option, or a detection that an Ampere CPU is being used, before including into pre-built binary kernels.

Which distro’s would that be?

Honestly I don’t remember, I’ve seen here on the forums that some one included the patches. But who - not sure. Not a major distro for sure.

There has been a huge update on drm / xe / xe kernel driver · GitLab
The underlying kernel is now 6.10-rc3 and of course a lot of updates on the xe driver that seem to have been merged from an internal repo.

Did anyone try this? I haven’t been lucky; driver loads, no error messages, but screen stays blank.

Using a Sparkle Intel Arc A310 Eco.

I would love to see this running: single slot, low profile, half length, low power consumption, yet potentially much more powerful than similar sized cards.
