I spent a while today reading up on the URB and thread management issues on the 965, and I think I spotted a few bugs in the code. I'm hoping that someone else can review the fixes for correctness, as I'm still not entirely convinced of the changes. I separated them out for easier bisecting.
The performance change of tweaking URB management seems pretty minimal so far, though I've only been using OA for testing (and it's not terribly high poly count). I've seen up to 5% improvement today from playing with it, and there's probably that much more from improving the preferred_nr_entries fields in brw_urb.c. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Mesa3d-dev mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/mesa3d-dev
