  * %AMDGPU_GEM_DOMAIN_CPU   System memory that is not GPU accessible.
  * Memory in this pool could be swapped out to disk if there is pressure.
  *
  * %AMDGPU_GEM_DOMAIN_GTT   GPU accessible system memory, mapped into the
  * GPU's virtual address space via gart. Gart memory linearizes non-contiguous
  * pages of system memory, allows GPU access system memory in a linearized
  * fashion.
  *
  * %AMDGPU_GEM_DOMAIN_VRAM  Local video memory. For APUs, it is memory
  * carved out by the BIOS.
  *
  * %AMDGPU_GEM_DOMAIN_GDS   Global on-chip data storage used to share data
  * across shader threads.
  *
  * %AMDGPU_GEM_DOMAIN_GWS   Global wave sync, used to synchronize the
  * execution of all the waves on a device.
  *
  * %AMDGPU_GEM_DOMAIN_OA    Ordered append, used by 3D or Compute engines
  * for appending data.
