Re: [PATCH 1/6] drm/msm/a6xx: Fix stale rpmh votes after suspend

[Michael Burch]

On X1E80100 (Dell XPS 13 9345) this patch seems to cause poweroff to
reboot instead. Reverting just the FW_START hunk avoids it, and so does
keeping the GPU awake until shutdown, so I suspect the PDC being asleep
at system off.

I've posted a fix, "drm/msm/adreno: Leave the GPU RSC awake for system
poweroff":
https://lore.kernel.org/all/20261003193518.13811-1-me@xxxxxxxxxxxxxxxx/

On this machine it resolves the reboot: poweroff and reboot work on AC
and battery, and deep suspend still drops the GPU votes. There may be a
better approach, e.g. waking only the RSC; happy to test.

Thanks,
Michael
