Working version, at least locally now. :)
This uses ww locking to ensure all buffer objects are locked during
submission. We still rely on struct_mutex to only submit one execbuf
at a time, but this is more because we cannot support parallel
submission yet without risking -EBUSY. When all code is converted to use
per-object locking, we can get rid of the BKL.
Chris Wilson (2):
drm/i915: Drop inspection of execbuf flags during evict
drm/i915/gem: Extract transient execbuf flags from i915_vma
Maarten Lankhorst (11):
drm/i915: Separate lookup and pinning in execbuf.
drm/i915: Add an implementation for i915_gem_ww_ctx locking, v2.
drm/i915: Remove locking from i915_gem_object_prepare_read/write
drm/i915: Parse command buffer earlier in eb_relocate(slow)
drm/i915: Use per object locking in execbuf on top of struct_mutex,
v2.
drm/i915: Use ww locking in intel_renderstate.
drm/i915: Add ww context handling to context_barrier_task
drm/i915: Nuke arguments to eb_pin_engine
drm/i915: Pin engine before pinning all objects
drm/i915: Rework intel_context pinning to do everything outside of
pin_mutex
drm/i915: Make sure execbuffer always passes ww state to i915_vma_pin.
