[PATCH v2 0/4] AMDKFD (AMD GPU compute) support for device cgroup.

[Kasiviswanathan, Harish]

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 redner device files.

v2: Exporting devcgroup_check_permission() instead of
__devcgroup_check_permission() as per review comments.

Harish Kasiviswanathan (4):
  drm/amdkfd: Store kfd_dev in iolink and cache properties
  drm/amd: Pass drm_device to kfd
  device_cgroup: Export devcgroup_check_permission
  drm/amdkfd: Check against device cgroup
