2015-07-28drm/i915: Keep the mm.bound_list in rough LRU orderChris Wilson
When we shrink our working sets, we want to avoid stealing pages from objects that likely to be reused in the near future. We first look at inactive objects before processing active objects - but what about a recently active object that is about to be used again. That object's position in the bound_list is ordered by the time of binding, not the time of last use, so the most recently used inactive object could well be at the head of the shrink list. To compensate, give the object a bump to MRU when it becomes inactive (thus transitioning to the end of the first pass in shrink lists). Conversely, bumping on inactive makes bumping on active useless, since when we do have to reap from the active working set, everything is going to become inactive very quickly and the order pretty much random - just hope for the best at that point, as once we start stalling on active objects, we can hope that the rebinding neatly orders vital objects.
