Better to put the fence outside amdgpu_gem_va_update_vm. Since it is passed to
the caller, and the caller must keep one reference at least until this fence is
no longer needed.
Thanks

The fence in amdgpu_gem_va_update_vm is not used after
amdgpu_gem_update_bo_mapping.

In order for SDMA not to be switched between VM_INVALIDATION
request and ack, use an single VM_INVALIDATION packet in function
sdma_v5_2_ring_emit_vm_flush.

er is still
accessing the "invalidated" BO.
I am not familiar with amdgpu_vm_bo state machine, so I don’t know if it is an
code error or an design error.
Thanks

invalidated BO.
Agree with Trigger. Seems kfd eviction should been synced to move notify, not
the move action.
Thanks

It leads to race condition if amdgpu_bo is marked as invalid
before it is really moved.

Subject: [PATCH v3] drm/amd/amdgpu: Update RLC_SPM_MC_CNT by ring wreg
[Why]
RLC_SPM_MC_CNTL can not updated by MMIO
since MMIO protection is enabled during runtime in
guest machine.
[How]
Submit command of wreg in amdgpu ring to update
RLC_SPM_MC_CNT.

The variable "chunk_ptr" should be a pointer pointing
to a struct drm_amdgpu_cs_chunk instead of to a pointer
of that.
