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.
