Danilo, Boris
As you might know we have a task to complete a VM_BIND locking document
including userptr gating the Xe driver upstreaming. I have version 3 of
that document out as a patch
https://patchwork.freedesktop.org/series/122508/
updated with the latest gpuvm changes, including the fine-grained
locking plus userptr locking as done in the Xe driver.
It would be greatly appreciated if you could read through and come with
suggestions / objections / acks. The idea is this document will simply
be updated as drm_gpuvm evolves. In particular the userptr area
currently follows Xe locking and probably needs to be adjusted if / when
we get userptr in drm_gpuvm.
Thanks,
Thomas
