The later can obviously fail. The helpers are just so we have a place to throw debug asserts into, maybe there are other needs for in-kernel caches. > Also, there are a couple iterations of the work-in-progress patches. Do you prefer a > cache per ring or a single cache shared by all rings? I've pondered a bunch of reasons for/against the two approaches and I think it won't really matter. Maybe slightly leaning towards per-ring caches since then objects retire in order. Well, until we do preemption ;-) -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
