Hello all,
I have a HP Elite x360 1049 G9 2-in-1 notebook running fedora 38 with an Adler Lake intel video card.
After upgrading to kernel 6.2.13 (as packaged by fedora), I started seeing severe video glitches made of random pixels in a vertical band occupying about 20% of my screen, on the right. The glitches would happen both with X.org and wayland.
I checked that vanilla 6.2.12 does not have the bug and that both vanilla 6.2.13 and vanilla 6.3.2 do have the bug.
I bisected the problem to commit e2b789bc3dc34edc87ffb85634967d24ed351acb (it is a one-liner reproduced at the end of this message).
I checked that vanilla 6.3.2 with this commit reverted does not have the bug.
I am CC-ing every e-mail appearing in this commit , I hope this is ok, and I apologize if it is not.
I have filled a fedora bug report about this, see https://bugzilla.redhat.com/ show_bug.cgi?id=2203549 . You will find there a small video (made with fedora kernel 2.6.14) demonstrating the issue.
Some more details:

drm/i915: Fix fast wake AUX sync len
commit e1c71f8f918047ce822dc19b42ab1261ed259fd1 upstream.
Fast wake should use 8 SYNC pulses for the preamble and 10-16 SYNC pulses for the precharge. Reduce our fast wake SYNC count to match the maximum value. We also use the maximum precharge length for normal AUX transactions.

Couple of experiment you could do:
Try disabling PSR completely by adding "i915.enable_psr=0" into your kernel parameters
if this helps on your issue remove "i915.enable_psr=0" from kernel parameters and try using more loose PSR latency configuration by adding "i915.psr_safest_params=1" into your command line parameters.
Thank You in advance,
Jouni Högander

drm/i915: Fix fast wake AUX sync lencommit e1c71f8f918047ce822dc19b42ab1261ed259fd1 upstream. Fast wake should use 8 SYNC pulses for the preamble and 10-16 SYNC pulses for the precharge. Reduce our fast wake SYNC count to match the maximum value. We also use the maximum precharge length for normal AUX transactions.

Hello all,
I have a HP Elite x360 1049 G9 2-in-1 notebook running fedora 38 with an Adler Lake intel video card.
After upgrading to kernel 6.2.13 (as packaged by fedora), I started seeing severe video glitches made of random pixels in a vertical band occupying about 20% of my screen, on the right. The glitches would happen both with X.org and wayland.
Please file a bug at https://gitlab.freedesktop.org/drm/intel/issues/new boot with "log_buf_len=4M drm.debug=0xe" passed to kernel cmdline, and attach the resulting dmesg to the bug.
Thank you for your answer, I have just opened the issue as requested.

Thanks for the ticket link. Now telling regzbot (and updating the culprit since you also mention the mainline commit that I assume to be the culprit [please verify if it is indeed the case]):
