isn't already selected to enabled full userptr support.
-config DRM_AMDGPU_GART_DEBUGFS
- bool "Allow GART access through debugfs"
- depends on DRM_AMDGPU
- depends on DEBUG_FS
- default n
- help
- Selecting this option creates a debugfs file to inspect the mapped
- pages. Uses more memory for housekeeping, enable only for debugging.
