Unable to find iGPU driver on EHL x6212RE SKUs

[ngboonhai]

Already follow the steps and install the iGPU driver into system, but still got issues to load and detect the driver for EHL processor stated above. 

GPGPU: Ubuntu 20.04 (focal) (intel.com)

GPGPU: Intel Iris Xe MAX graphics

Hello ngboonhai

Thank you for posting on the Intel️® communities. Please let us investigate this request and the updates will be posted on the thread.

Hi David, 

       I got help from PG HSPE graphic team and know there is some configuration needed on EHL x6212RE as edit /etc/default/grub, then add "i915.force_probe=4555 i915.enable_guc=2". Btw, we also have same problem on ADL-S i9 12900TE & 12900E SKUs on Ubuntu 20.04.3 LTS (kernel version 5.11.0-27) even PG HPSE graphic team also failed to help on ADL-S SKUs. Perhaps the team also can look into ADL-S SKUs issues also, thank you.

this seems to resolve improve random hanging issues on the x6212RE using OpenVINO for GPU inference.

Hello ngboonhai

Thanks for the update, in this case the Intel Atom® x6212RE Processor uses Intel® UHD Graphics and not Intel® Iris® Xe Max Graphics. These drivers are provided and maintained by the Linux* distribution vendors and not by Intel, we recommend contacting the Linux* Operating System Vendors for more information:

You can also verify this article on how to report graphics issues on Linux drivers:

Hi David,

      Noted and thanks.

I posted about a related issue on the Media-SDK Slack channel but have not received any feedback. The issue is, GPU drivers behave differently between the x6212RE, x6413E and x6425E/RE:

Example 1) We followed official Linux driver installation guides and pulled from the official repositories. VAAPI was present and operational on x6425E/RE but not on x6212RE or x6413E. Only after installing OpenVINO drivers we got VAAPI on all platforms.

Example 2) Even after OpenVINO installation, x6212RE is having issues with GPU inference whereas the x6425E/RE has no issues. I will add more comments on this below as your "i915.force_probe=4555 i915.enable_guc=2" suggestion seems to have reduced the frequency of GPU hanging.

Would appreciate your guidance on where to report under what tags. Thank you!

here is the dmesg when the GPU hangs during OpenVINO inference on the x6212RE:

[40906.406659] i915 0000:00:02.0: [drm] Resetting rcs0 for preemption time out
