--- Comment #5 from Chris Wilson <ch...@chris-wilson.co.uk> 2011-02-08 06:21:23 PST --- Another perspective. Running without the patch: =0 sandybridge:~$ DISPLAY=:0.0 ./copy-tex-subimage # gt1 time for glBlitFramebuffer = 119331 time for glCopyTexSubImage2D = 1518 =0 sandybridge:~$ DISPLAY=:0.1 ./copy-tex-subimage # radeon 5770, r600g time for glBlitFramebuffer = 15952 time for glCopyTexSubImage2D = 16237 And after applying the patch: =0 sandybridge:~$ DISPLAY=:0.0 jhbuild run ./copy-tex-subimage time for glBlitFramebuffer = 4706 time for glCopyTexSubImage2D = 1519 =0 sandybridge:~$ DISPLAY=:0.1 jhbuild run ./copy-tex-subimage time for glBlitFramebuffer = 16318 time for glCopyTexSubImage2D = 16649 Which is less of a case that we need to implement a fast path for glBlitFramebuffer, but that i965 needs to seriously fix the bottleneck uncovered by the current code. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
