Bug 2133977

Created attachment 1917425 [details]
journalctl -b 2 -k

1. Please describe the problem:
When playing videos with mpv and Firefox, or when using desktop effects (Plasma Workspaces with kwin X11), moving the mouse results in frames drop, almost freezing the video.

2. What is the Version-Release number of the kernel:
Kernel 5.19.12 and later (including 6.x.x)


3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at
   https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :

It worked on 5.19.11.


4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:

Yes, launch a video in mpv and move the mouse: frames drop guaranteed.


5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:

Yes.

6. Are you running any modules that not shipped with directly Fedora's kernel?:

No.

7. Please attach the kernel logs. You can get the complete kernel log
   for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
   issue occurred on a previous boot, use the journalctl ``-b`` flag.

Done.


Bisection:

Since the changes affecting amdgpu were fairly limited between 5.19.11 and 5.19.12, I was able to bisect the problem to this commit:

8442bc8426d1264496468066498b196aef5453a7 is the first bad commit
commit 8442bc8426d1264496468066498b196aef5453a7
Author: Hamza Mahfooz <hamza.mahfooz>
Date:   Tue Sep 6 15:01:49 2022 -0400

    drm/amdgpu: use dirty framebuffer helper
    
    [ Upstream commit 66f99628eb24409cb8feb5061f78283c8b65f820 ]
    
    Currently, we aren't handling DRM_IOCTL_MODE_DIRTYFB. So, use
    drm_atomic_helper_dirtyfb() as the dirty callback in the amdgpu_fb_funcs
    struct.
