I have a Dell Latitude 7450 with an Intel Core Ultra 7 165U.
In my tests so far the Xe driver, while providing the best experience right at boot (correct resolutions etc.), was very unstable.
Everytime I watched a video either with MPV or in the browser the device crashed after max. 10 minutes.
I'm currently running the i915 driver and so far it has been working fine.
Therefore I'm not sure it is fair to say that i915 is buggy on Meteor Lake. However I'm not the best when it comes to hardware.

Interesting. I found the i915 driver to be unusably buggy on an XPS9340, while the xe driver works fine. I'll look more into it and see if there's some other factor.

I'm currently using the Dell Precision 5390 with an Intel Core Ultra 7 165H with this patch and also the Xe driver and haven't noticed any issues so far. But I'm using this system only for 2 days.

Hm interesting, that is a very similar CPU.
My setup is here, AFAIK I’m not doing something exotic but maybe miss something obvious.

I tried it again yesterday and Xe failed reproducible when watching a video with the same config except for the force_probe.
Which looked like this: https://git.2li.ch/Nebucatnetzer/nixos/commit/edeac6d6922c29e78126386c563e976e79cff23c
@Sh3Rm4n is suspend working for you? If so are you using an encrypted drive?

I'm using an encrypted drive and haven't explicitly checked suspend so far, but I think it is currently not working correctly. I'll recheck again.

I just see this, the boot is because I killed the system.

Just to be sure I tested this PR and the settings from nixos-hardware explicitly and I'm seeing the same behaviour.
In addition I have to force_probe the Xe driver otherwise the notebook doesn't detect my external monitor.

What just came to my mind.
Are you guys using X11 or Wayland or wouldn't that make a difference?

Solved the suspend problem by removing the webcam option.
Sorry for the detour.

BTW. shouldn't both the machine and the CPU files be added to the flake.nix? |
