77  *
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 linezrized
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.
