[PATCH 2/2] drm/amdgpu: use new reset-affected accessors for userspace interfaces
Alex Deucher
alexander.deucher at amd.com
Fri Feb 16 15:13:22 UTC 2024
Use the new reset critical section accessors for debugfs, sysfs,
and the INFO IOCTL to provide proper mutual exclusivity
to hardware with respect the GPU resets.
