drm/amdgpu: add new unlocked flag for PTE updates

2020-04-28T20:20:30Z

For HMM support we need the ability to invalidate PTEs from a MM callback where we can't lock the root PD. Add a new flag to better support this instead of assuming that all invalidation updates are unlocked. Signed-off-by: Christian König Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: fix race between pstate and remote buffer map

2020-04-22T22:11:46Z

Vega20 arbitrates pstate at hive level and not device level. Last peer to remote buffer unmap could drop P-State while another process is still remote buffer mapped. With this fix, P-States still needs to be disabled for now as SMU bug was discovered on synchronous P2P transfers. This should be fixed in the next FW update.

drm/amdgpu: stop adding VM updates fences to the resv obj

2019-12-09T22:02:15Z

Don't add the VM update fences to the resv object and remove the handling to stop implicitely syncing to them. Ongoing updates prevent page tables from being evicted and we manually block for all updates to complete before releasing PDs and PTS. This way we can do updates even without the resv obj locked.
