Hey, Thank you for looking at the patch. It seems you're worried about lifetime issues. When the timeline is pinned, i915_active takes a reference on the vma pin and timeline. intel_timeline_read_hwsp() uses the existing i915_active trick to keep the timeline alive, so this will stay working correctly as intended. :) Can I add your reviewed-by for the patch when I submit it to the ml again?
