     78 * %AMDGPU_GEM_DOMAIN_CPU	System memory that is not GPU accessible.
     79 * Memory in this pool could be swapped out to disk if there is pressure.
     80 *
     81 * %AMDGPU_GEM_DOMAIN_GTT	GPU accessible system memory, mapped into the
     82 * GPU's virtual address space via gart. Gart memory linearizes non-contiguous
     83 * pages of system memory, allows GPU access system memory in a linearized
     84 * fashion.
     85 *
     86 * %AMDGPU_GEM_DOMAIN_VRAM	Local video memory. For APUs, it is memory
     87 * carved out by the BIOS.
     88 *
     89 * %AMDGPU_GEM_DOMAIN_GDS	Global on-chip data storage used to share data
     90 * across shader threads.
     91 *
     92 * %AMDGPU_GEM_DOMAIN_GWS	Global wave sync, used to synchronize the
     93 * execution of all the waves on a device.
     94 *
     95 * %AMDGPU_GEM_DOMAIN_OA	Ordered append, used by 3D or Compute engines
     96 * for appending data.
