Cycles Intel oneAPI device feedback

So, I tried the whole thing with a Ubuntu 22.04 distrobox following the official guide on Intel’s website only installing the drivers mentioned (except for the kernel, which is shared from the host system) and I’m getting the same crash scenario here:

./blender --debug-cycles --verbose 6

fish: Job 1, './blender --debug-cycles --verb…' terminated by signal SIGABRT (Abort)

Unfortunately, debug output is not very useful.

resizeable bar is activated in my BIOS and seems to be detected as such, assuming for the A750 the memory address is different than the one mentioned in the Intel docs:

lspci -v |grep -A8 VGA

lspci: Unable to load libkmod resources: error -2
2b:00.0 VGA compatible controller: Intel Corporation Device 56a1 (rev 08) (prog-if 00 [VGA controller])

	Expansion ROM at fc000000 [disabled] [size=2M]
	Capabilities: <access denied>

So for the moment, I have to assume that this is either an issue with trying to run blender in a container and/or an issue with using kernel 6.1. Since I don’t want to install Ubuntu on “bare metal”, I guess I will have to wait for drivers and compatibility to improve for other distributions/configurations.

It’s definitely not explicit but seeing the stage at which it’s failing is still helpful, here it’s as soon as it allocates memory. That confirms an incompatibility across some of your driver components, especially intel-gmmlib vs the rest.
You’re right it will improve over time but if you still want to get it working now with kernel 6.1, I recommend using all components listed in latest release from GitHub - intel/compute-runtime: Intel® Graphics Compute Runtime for oneAPI Level Zero and OpenCL™ Driver instead of in https://dgpu-docs.intel.com/releases/stable_449_3_20220930.html that is targeting a more specific kernel.

Unfortunately, that didn’t help. I installed all packages from the latest release (which basically put me in the same situation I had been before with Arch), but Blender still crashes with the same error message at the same point.

That was still worth trying. Everything upstream is still expected to work: Intel Arc Graphics A750 + A770 Are Ready To Run On Open-Source Linux Drivers - Phoronix had success with it.
Do you have Mesa 22.2 or 22.3, latest linux-firmware.git on the host?
It may be smoother to make the whole stack work on your Fedora first before looking at distrobox.

Yes, I have also tried with the very latest Mesa drivers (mesa-git 22.3) and firmware drivers from git. No difference. Performance and compatibility in 3D applications on Linux is still very bad overall, as other users on e.g. reddit are also reporting. I was hoping to be at least able to test/run the cards compute capabilities in the mean time, but Blender won’t let me.

Installing the whole stack on Fedora is a lot more tricky than on Ubuntu and Arch, but might be worth a shot. Maybe Intel could be convinced to distribute the drivers in a more distro agnostic way in the future :wink:

For now, I will try to build blender myself and see, if that makes any difference.

I’m not expecting it to make any difference considering the current issue, sorry. Expect it to be a smooth process though, since on Linux the whole toolchain is open source down to the graphics compiler and pre-packaged on svn :slight_smile:

The dgpu-docs website focuses on a restricted set of distributions but repositories and work upstream are distro agnostic. It takes time for latest developments to reach all distributions and it’s always more complex if you want to stay ahead to use latest hardware, I’m not sure what could be done to make it easier.

I’m using ubuntu 22.04 with xorg and I don’t know the perf and compatibility with other games and applications but I can say Blender is running well there with similar performance as Windows.

I just came by to report hat after 2 weeks worth of driver updates, testing many different distros and the most recent versions of blender, I still can’t get Cycles OneAPI working on Linux with Intel Arc 750. So no progress has been made. I always get the same crash and error message, as mentioned before:

terminate called after throwing an instance of 'sycl::_V1::runtime_error'
  what():  Native API failed. Native API returns: -997 (The plugin has emitted a backend specific error) -997 (The plugin has emitted a backend specific error)

Since there are no reports from other users so far, the issue could be anything from faulty hardware on my end to an actual bug in the blender implementation of Cycles oneapi or drivers simply still not being up to snuff. I will report back periodically in case I make any progress.

I’ve been able to run blender cycles successfully with Arc A380 using official Intel’s linux driver release.
Installed drivers and APIs as described here (has to downgrade kernel from 6.0 to 5.19-oem):

What happened before the kernel downgrade? Did blender crash or was your card simply not detected as a compatible device?

The installation didn’t go well with kernel 6.0. At some stage I got message about “unsupported kernel”.
This happened when I was running the following line from guide:
sudo apt-get install -y intel-i915-dkms intel-fw-gpu
So I re-installed Ubuntu 22.04 and installed kernel 5.17.0-1019-oem (as described in guide, sorry, not 5.19 - my mistake).
Initially I had Ubuntu 22.10 with mesa 22.3 and latest Neo driver, Blender didn’t detect Intel GPU hardware.

Update: Blender still crashes immediately even with version 3.5 Beta whenever I enable GPU Compute for Cycles with my Intel Arc A750

I am running Fedora 37 on Kernel 6.0.10-300, intel-compute-runtime version 22.43.24558, mesa 22.2.3

As stated above I have tested other distrubtions with different kernel and driver versions with the same result.

Currently all reports of people sucessfully running Blender with Cycles OneAPI on Intel Arc have been from people running Ubuntu with OEM Kernel 5.17 (+ DKMS modules by Intel). Is this being looked into to make Cycles oneAPI usable (i.e. not crash) with other/newer Linux Kernels so we are not forced to use Ubuntu?

I have attached my console output (running blender with SYCL_PI_TRACE=2 and --debug-cycles --verbose 6) in case this might be helpful:

Moderation notice: fixed your logs a tiny bit, next time please reconsider posting a 2km long log directly into the forum.

Your logs show it’s failing a bit further than before, during memory copies, after the allocations.
Release 22.43.24595.30 · intel/compute-runtime · GitHub just got released and now claims production quality for Intel Arc when used with DKMS driver so it has good chances to work.
If it still doesn’t work, next step will be to open a bug report there.
