drm/amdgpu: fix and cleanup gmc_v9_0_flush_gpu_tlb_pasid

2023-09-26T20:55:09Z

Testing for reset is pointless since the reset can start right after the test. The same PASID can be used by more than one VMID, invalidate each of them. Move the KIQ and all the workaround handling into common GMC code. Signed-off-by: Christian König Reviewed-by: Alex Deucher Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: Update invalid PTE flag setting

2023-07-07T17:51:47Z

Update the invalid PTE flag setting with TF enabled. This is to ensure, in addition to transitioning the retry fault to a no-retry fault, it also causes the wavefront to enter the trap handler. With the current setting, the fault only transitions to a no-retry fault. Additionally, have 2 sets of invalid PTE settings, one for TF enabled, the other for TF disabled. The setting with TF disabled, doesn't work with TF enabled. Signed-off-by: Mukul Joshi Acked-by: Christian König Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: Override MTYPE per page on GFXv9.4.3 APUs

2023-06-09T13:59:08Z

On GFXv9.4.3 NUMA APUs, system memory locality must be determined per page to choose the correct MTYPE. This patch adds a GMC callback that can provide this per-page override and implements it for native mode. Carve-out mode is not yet supported and will use the safe default (remote) MTYPE for system memory.
