drm/amdgpu: resume gfx userqueues
This patch adds support for userqueue resume. What it typically does is
this:
- adds a new delayed work for resuming all the queues.
- schedules this delayed work from the suspend work.
- validates the BOs and replaces the eviction fence before resuming all
the queues running under this instance of userq manager.
V2: Addressed Christian's review comments:
- declare local variables like ret at the bottom.
- lock all the object first, then start attaching the new fence.
- dont replace old eviction fence, just attach new eviction fence.
- no error logs for drm_exec_lock failures
- no need to reserve bos after drm_exec_locked
- schedule the resume worker immediately (not after 100 ms)
- check for NULL BO (Arvind)
V5: Rebased wrt changes in suspend patch
- moved amdgpu_userqueue_validate_vm_bo in this patch
- initialized ret in resume_all
V6: Rebase
V7: Addressed review comments from Christian
- Do not use list_for_each_safe() with vm->invalidated, its not
correct way
V8: Fixed the race condition between suspend/close/fence
