Subject: [PATCH] drm/amd/amdgpu: Change vram debugfs to NO_KIQ for
VM environments
Signed-off-by: Tom St Denis <[email protected]>
Reviewed-by: Alex Deucher <[email protected]>
Reviewed-by: Christian König <[email protected]>
BTW: There are another instance in amdgpu_ttm_access_memory() which
needs to be fixed as well.
Might be a good idea to separate that into
amdgpu_vram_read/amdgpu_vram_write functions as well.
Regards,
Christian.
