If this brings the freelist under control, the next item is judicious use of cond_synchronize_rcu(). We just have to make sure we penalize the right hog. Otherwise, we have to shotgun apply i915_gem_flush_free_objects() and still find somewhere to put the rcu sync. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
