screen flicker after PSR2 enabled

Upload the apport log.

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 2007516

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

please test newer kernels, like oem-6.0, oem-6.1..

linux-oem-6.1 has the issue.

- Which mode does Windows use? PSR1 or PSR2?
- Does the panel generate IRQ correctly under Windows?

Test kernel did not correct the issue on my machine.

reply #8,

Could you dump the eDP PSR status?
# cat /sys/kernel/debug/dri/0/i915_edp_psr_status

Have you tried the driver parameter "options i915 enable_psr2_sel_fetch=0"? Does it work for you?

The patch is created by applying quirk for Dell machine [1], I'd like to check if it indeed take effect on your platform, could you dump lspci output by
$ lspci -nnvv

[1] https://patchwork.freedesktop.org/patch/524182/?series=114400&rev=1

In addition to that, please test the following kernel _without_ any kernel parameter:
https://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/current/amd64/

eDP dump file

lspci dump file

So far the artifact has _not_ returned running: 6.2.0-060200rc2drmintelnext20230228-generic

I'm seeing overall good behavior with this kernel.

I will need more information/assistance on how to apply the quirk. Do I download the patch files and execute them, or do I edit the grub file as described here:

https://askubuntu.com/questions/1455653/horizontal-colored-lines-appearing-on-display-ubuntu-22-04

Colin, can you please give this test kernel a try:
https://people.canonical.com/~khfeng/jammy-5.19-fast-wake/

The problem remains with the test kernel:
https://people.canonical.com/~khfeng/jammy-5.19-fast-wake/

I am also experiencing this issue on a brand new Lenovo X1 Carbon Gen 10 with a regular HD screen (1920x1200). The workaround of disabling PSR via altering grub options worked for me:

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_psr=0"

Should this bug description be generalized?

Please give this one a test:
https://people.canonical.com/~khfeng/lp2002986-2/

Actually there are two bugs -
- The original reported issue [0] happens on Sharp panel model 5457. The issue is still unresolved.
- A more pervasive issue [1] that happens on more panels is resolved in drm-tip kernel. The fix is not in mainline yet.

As for Ubuntu kernel v5.19, in addition to fix for [1], we also need another PSR fix. This is in the test kernel, please give it a try if possible.

This bug is awaiting verification that the linux-oem-6.1/6.1.0-1008.8 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Kernel 5.19.0-3035-generic x86_64 has good behavior.

I have not seen the artifacts with this version while performing the typical workflow that normally caused it to manifest.
