From: Thomas Hellström <thomas.hellstrom@xxxxxxxxx>
The vma resource are needed for asynchronous bind management and are
similar to TTM resources. They contain the data needed for
asynchronous unbinding (typically the vm range, any backend
private information and a means to do refcounting and to hold
the unbinding for error capture).
When a vma is bound, a vma resource is created and attached to the
vma, and on async unbinding it is detached from the vma, and instead
the vm records the fence marking unbind complete. This fence needs to
be waited on before we can bind the same region again, so either
the fence can be recorded for this particular range only, using an
interval tree, or as a simpler approach, for the whole vm. The latter
means no binding can take place on a vm until all detached vma
resources scheduled for unbind are signaled. With an interval tree
fence recording, the interval tree needs to be searched for fences
to be signaled before binding can take place.
But most of that is for later, this patch only introduces stub vma
resources without unbind capability and the fences of which are waited
for sync during unbinding. At this point we're interested in the hold
capability as a POC for error capture. Note that the current sync waiting
at unbind time is done uninterruptible, but that's OK since we're
only ever waiting during error capture, and in that case there's very
little gpu activity (if any) that can stall.
v2:
- Fix the mock gtt selftest to bind with vma resources.
- Update a code comment.
- Account for rebinding the same vma with different I915_VMA_*_BIND flags
v3:
- Some style fixups.
- Move the sync fence wait to __i915_vma_evict instead of __i915_vma_unbind
to catch also the evict case on suspend.
v4:
- Remove a minor fix that incorrectly landed in this patch.
