  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

  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.
