drm/amdgpu: Add EXT_COHERENT support for APU and NUMA systems
On gfx943 APU, EXT_COHERENT should give MTYPE_CC for local and MTYPE_UC for nonlocal memory. On NUMA systems, local memory gets the local mtype, set by an override callback. If EXT_COHERENT is set, memory will be set as MTYPE_UC by default, with local memory MTYPE_CC. Add an option in the override function for this case, and add a check to ensure it is not used on UNCACHED memory. V2: Combined APU and NUMA code into one patch V3: Fixed a potential nullptr in amdgpu_vm_bo_update Signed-off-by: David Francis <David.Francis@amd.com> Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
