Our low-level wait routine has evolved from our generic wait interface that handled unlocked, RPS boosting, waits with time tracking. If we push our GEM fence tracking to use reservation_objects (required for handling multiple timelines), we lose the ability to pass the required information down to i915_wait_request(). However, if we push the extra functionality from i915_wait_request() to the individual callsites (i915_gem_object_wait_rendering and i915_gem_wait_ioctl) that make use of those extras, we can both simplify our low level wait and prepare for extending the GEM interface for use of reservation_objects. v2: Rewrite i915_wait_request() kerneldocs Signed-off-by:
