Subject: drm/amdgpu: Fix an error message in rmmod
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7270e8957eb9aacf5914605d04865f3829a14bce;p=linux.git

drm/amdgpu: Fix an error message in rmmod

[why]
In rmmod procedure, kfd sends cp a dequeue request, but the
request does not get response, then an error message "cp
queue pipe 4 queue 0 preemption failed" printed.

[how]
Performing kfd suspending after disabling gfxoff can fix it.
