Subject: [PATCH v5] drm/amd/display: Revert W/A for hard hangs on
DCN20/DCN21
I just tested patch v5 applied to amd-staging-drm-next (with HEAD
26c981e27e698c251ef3241f73ac846e66ad7fc3) and suspend and resume
work
fine. But as amd-staging-drm-next is still based on linux-5.13 I
had to
replace the mediatek wlan driver by the version from linux-5.16.
FYI it should likely cherry pick to 5.16 too if it's easier to test
there.
I was able to cherry-pick to rc8 no problem.
If you can please try any display hotplugging to make sure hotplugs
don’t
cause problems for you as well feel comfortable to add a Tested-by
tag.
Thanks,
Unfortunately the external HDMI port on my Notebook (Alpha 15 B5EEK/MS-
158L) does not seem to work out-of-the-box. This is a two GPU machine
03:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Navi
23 [Radeon RX 6600/6600 XT/6600M] (rev c3)
08:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
[AMD/ATI] Cezanne (rev c5)
The Desktop Environment (gnome with Xorg) is running on the integrated
Cezanne, but when I connect the external HDMI cable I get a dmesg
resume message from the Navi GPU. So this either requires some
additional configuration effort on my part or this is a story for
another bug report.
Unless this changes without this revert patch in place then I would say
a story for another bug report.
