Hi Nicolai,
that one should be fixed by "drm/amdgpu: fix PRT cleanup order in the
VM". Please test and/or review.
Thanks,
Christian.

Hi,
Some more testing uncovered a bug in cleanup paths. When the
application segfaults while PRT mappings exist, I get a WARN_ON (which
seems fairly straightforward) and occasionally also an RCU error
warning -- see the attached dmesg logs.
Regular application shutdown works fine, though.
Cheers,
Nicolai

Hi guys,
ok I finally found time to write an unit test for this and hammered
out the last few bugs.
Seems to work fine on my Tonga now. Please note that this set is
based on "fix race in GEM VA map IOCTL v2", without that patch you
will run into a NULL pointer dereference during PRT mapping.
Going to send out the unit test in a minute.
Regards,
Christian.
