Thanks for the reviews. I rebased this on amd-staging-drm-next, retested
and submitted.
Christian, do you want to do some graphics PASID and VMFault work on top
of that? I think I'll be working on more KFD upstreaming this week and
maybe look at this subject again next week.
Yeah, that's on my TODO list together with quite a bunch of other things.
Going to give that a try when I have time, but don't expect anything
before xmas.
Regards,
Christian.
Regards,
Felix

Rebased on adeucher/amd-staging-4.13 and tested on Vega10 (graphics)
and Kaveri (KFD). Meaningful graphics tests with retry faults enabled
will only be possible after PASID support is added to amdgpu_cs.
The chash table was moved to drivers/gpu/drm/amd/lib for now but is
ready to move to lib if needed. I have not got any feedback on LKLM
and I don't want that to hold up the patch series.
TODO:
* Finish upstreaming KFD
* Allocate PASIDs for graphics contexts
* Setup VMID-PASID mapping during graphics command submission
* Confirm that graphics page faults have the correct PASID in the IV
