I was saying there weren't any issues. I myself haven’t had any issues on gen 11 framework. I tested the arch-packaged versions, as well as the kernels directly from source.

Sorry for jumping in the middle of the thread. I believe that this is also reported by Fedora users on a Lenovo Carbon X1 (gen 9) as: https://bugzilla.redhat.com/show_bug.cgi?id=2130699 So it would be good to add a: Link: https://bugzilla.redhat.com/show_bug.cgi?id=2130699 tag to the commit which ends up fixing this.

Looks like stable is at least missing this pile of stuff: 50759c13735d drm/i915/pps: Keep VDD enabled during eDP probe 67090801489d drm/i915/pps: Reinit PPS delays after VBT has been fully parsed 8e75e8f573e1 drm/i915/pps: Split PPS init+sanitize in two 586294c3c186 drm/i915/pps: Stash away original BIOS programmed PPS delays 89fcdf430599 drm/i915/pps: Don't apply quirks/etc. to the VBT PPS delays if they haven't been initialized 60b02a09598f drm/i915/pps: Introduce pps_delays_valid() But dunno if even that is enough.

Thanks. 5.19.13 is now released with 8 reverts for this driver, hopefully that sould resolve this issue. thanks, greg k-h ^ permalink raw reply [flat|nested] 22+ messages in thread

Not my area of expertise, so it's a wild guess, but display flickering made me wonder if this change is the culprit: https://lore.kernel.org/all/20220926100814.131449678@linuxfoundation.org/ If it is, simply starting with "i915.enable_psr=0" might already help. but as I said, just a wild guess after briefly looking into the problem. Anyway, for the rest of this mail: [TLDR: I'm adding this regression report to the list of tracked regressions; all text from me you find below is based on a few templates paragraphs you might have encountered already already in similar form.] Thanks for the report. To be sure below issue doesn't fall through the cracks unnoticed, I'm adding it to regzbot, my Linux kernel regression tracking bot: #regzbot ^introduced v5.19.11..v5.19.12 #regzbot title Display flickering on Framework laptop #regzbot ignore-activity This isn't a regression? This issue or a fix for it are already discussed somewhere else? It was fixed already? You want to clarify when the regression started to happen? Or point out I got the title or something else totally wrong? Then just reply -- ideally with also telling regzbot about it, as explained here: https://linux-regtracking.leemhuis.info/tracked-regression/ Reminder for developers: When fixing the issue, add 'Link:' tags pointing to the report (the mail this one replies to), as explained for in the Linux kernel's documentation; above webpage explains why this is important for tracked regressions. Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) P.S.: As the Linux kernel's regression tracker I deal with a lot of reports and sometimes miss something important when writing mails like this. If that's the case here, don't hesitate to tell me in a public reply, it's in everyone's interest to set the public record straight. ^ permalink raw reply [flat|nested] 22+ messages in thread

Ick. Ok, can you test your own kernel build out? If I provide a patch that reverts the what I think are offending commits, can you test it? Also, does 6.0-rc7 also have this same problem? That should be tested first here, and if that's a problem, then we can get the i915 developers involved. thanks, greg k-h ^ permalink raw reply [flat|nested] 22+ messages in thread
