I added a call to permit_hardware_blit after the force_tilling check and now 720x480p videos are working even with tilling enabled. But it looks like very small texture doesn't work at all and very large textures/surfaces like 1280x1080 have artefacts. I will try to investigate it a bit further. > Pageflipping should help as > well for fullscreen 3D: > http://cgit.freedesktop.org/xorg/driver/xf86-video-ati/log/?h=kms-pflip > but for that you'll need drm-next: > http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=shortlog;h=refs/heads/drm-next Ok i will try it if time permits. Where can i ask for write permission to mesa master repository? I have some patches ready who are clearly bug fixes, or should I post them for manual inclusion?
