Title:
HDMI output freezes under current/proposed impish kernels
Status in linux-raspi package in Ubuntu:
Fix Released
Status in linux-raspi source package in Impish:
Fix Released
Bug description:
[Impact]
The UI of Impish desktop for raspi occasionally freezes which can be
triggered by playing videos and moving windows around. Seems to happen
more frequently when using higher resolutions and/or higher refresh
rates (higher than 1920x1080@60Hz).
Kernel errors are along the lines of:
[ 513.762138] [drm:drm_crtc_commit_wait [drm]] *ERROR* flip_done timed out
[ 513.762288] [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]]
*ERROR* [CRTC:76:crtc-3] co
mmit wait timed out
[ 513.762381] [drm:drm_atomic_helper_wait_for_flip_done [drm_kms_helper]]
*ERROR* [CRTC:76:crtc-3] flip_
done timed out
[Test Case]
Install current Impish desktop for raspi on a Pi 4. Use a high-
refresh/resolution monitor. Play videos, move windows around.
[Fix]
The Pi foundation identified a couple of upstream vc4 commits that
seem to interfere with their downstream patches. Revert those to match
the Pi foundations currently released 5.10 kernel.
[Where Problems Could Occur]
The changes are confined to the vc4 driver, so problems would only
show up if that driver is in use. Which is only the case for the
Ubuntu raspi desktop image, so server images should not be impacted at
all.
[Original Description]
Under the current (5.13.0-1007.8) or proposed (5.13.0-1008.9) kernels
for the Ubuntu Pi pre-installed desktop impish release, the HDMI
output occasionally freezes. A known workaround at this time is to
change the following line in /boot/firmware/config.txt:
dtoverlay=vc4-kms-v3d
To the following:
dtoverlay=vc4-fkms-v3d
In other words, to use the "fake" KMS overlay (fkms) instead of the
"full" KMS overlay (kms).
I've been unable to determine a reliable method of guaranteeing a
freeze, but it appears to occur much more readily when video playback
is occurring, and when other interactions (especially moving windows
around, minimizing, restoring) occurs simultaneously. Display suspend
also periodically causes the same hang, which made me suspect this
might be related to #1944397 but it appears that had a separate cause
(now resolved).
The following dmesg outputs have been observed immediately after the
display hang; this one from 1007.8:
[ 513.762138] [drm:drm_crtc_commit_wait [drm]] *ERROR* flip_done timed out

And a similar one from 1008.9 (note that most of the time, the stack
trace *doesn't* appear hence I'm not sure if it's related to the
display freeze itself, or something auxiliary):

I can produce this same stack trace, but *without* a corresponding
freeze by manually locking the desktop (Super+L) and waiting for the
display fade. However, after the stack trace appears, one can press a
key to bring the display back and login again happily. Here are
several repeated traces from such activity under the 1008.9 proposed
kernel:

Note that even when the display is frozen (and cannot be resurrected),
only the display driver appears to crash; the system remains
operational (at least for some time) happily responding to SSH login
requests or, if video is playing, continuing audio output.
The same occurs with the current linux-firmware-raspi2 release (which
the above stack traces were taken from), or with the latest firmware
(installed from an experimental package in my
https://launchpad.net/~waveform/+archive/ubuntu/firmware PPA).
