A few questions:
- iirc Ben's non-blocking stuff also worked for non-llc machines - I guess
you haven't looked into this because we don't have a non-llc platform
that runs ungine?
Tropics works on Ironlake, too, it's just slow. Haven't tried earlier.
- in my pwrite experience, writing through cpu maps beats writing through
the gtt on llc machines. This has the added benefit that it reduces
pressure on the mappable gtt. Have you tried that, too?
Cheers, Daniel
