What I was expecting to see were gem_create()s every loop. I only feel confident in say that a pair of freshly allocated and bound objects are likely to line up against each other (so long as space is not fragmented). I would allocate a new device fd for the test, leak the individual handles on every try, then close the fd at the end of the test to avoid having to track all the allocations. That's the pattern I was looking for when I skimmed over your test. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
