| H A D | msm_fence.h | 95d1deb0 Mon Apr 11 16:58:38 CDT 2022 Rob Clark <robdclark@chromium.org> drm/msm/gem: Add fenced vma unpin
With userspace allocated iova (next patch), we can have a race condition
where userspace observes the fence completion and deletes the vma before
retire_submit() gets around to unpinning the vma. To handle this, add a
fenced unpin which drops the refcount but tracks the fence, and update
msm_gem_vma_inuse() to check any previously unsignaled fences.
v2: Fix inuse underflow (duplicate unpin)
v3: Fix msm_job_run() vs submit_cleanup() race condition
