Hi Tejun, Sorry. Resending these patches as I got distracted with other stuff and couldn't follow through. As per our previous discussion the plan was to upstream these changes (mainly patch 3 "Export devcgroup_check_permission") through Alex Deucher's amd-staging-drm-next and Dave Airlie's drm-next trees. I am planning to take this route. I have rebased my patches to amd-staging-drm-next. You and Roman acked patch 3, it will be great if I can Reviewed-by, so that the upstream path can be smoother. Best Regards, Harish ***** Original note about this patch series for ref. **** amdkfd (part of amdgpu) driver supports the AMD GPU compute stack. amdkfd exposes only a single device /dev/kfd even if multiple AMD GPU (compute) devices exist in a system. However, amdgpu drvier exposes a separate render device file /dev/dri/renderDN for each device. To participate in device cgroup amdkfd driver will rely on these rendner device files
