drm/amdgpu: re-create idle bo's PTE during VM state machine reset

2023-12-19T20:28:10Z

Idle bo's PTE needs to be re-created when resetting VM state machine. Set idle bo's vm_bo as moved to mark it as invalid. Fixes: 55bf196f60df ("drm/amdgpu: reset VM when an error is detected") Signed-off-by: ZhenGuo Yin Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdkfd: Improve amdgpu_vm_handle_moved

2023-11-03T16:18:32Z

Let amdgpu_vm_handle_moved update all BO VA mappings of BOs reserved by the caller. This will be useful for handling extra BO VA mappings in KFD VMs that are managed through the render node API. v2: rebase against drm_exec changes (Alex) Signed-off-by: Felix Kuehling Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: Add EXT_COHERENT support for APU and NUMA systems

2023-10-27T18:15:16Z

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.

drm/amdgpu: refine fault cache updates

2023-10-05T21:49:51Z

Don't update the fault cache if status is 0. In the multiple fault case, subsequent faults will return a 0 status which is useless for userspace and replaces the useful fault status, so only update if status is non-0. Reviewed-by: Christian König Signed-off-by: Alex Deucher
