76 * DOC: memory domains
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 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.
97 *
98 * %AMDGPU_GEM_DOMAIN_DOORBELL	Doorbell. It is an MMIO region for
99 * signalling user mode queues.
