Some people in this thread were saying "there's no ATI support / the ATI support is very bad" when it wasn't correct.

There's the old, slow, DMAless utah drivers (GL HW acceleration for X 3.3) for anyone who wants to port them to the XFree 4 with DRI. I remember like 17fps in quake3 on some low settings with a TNT2U 32MB/400Mhz Celeron. We even had some code released by nvidia that did sample dma (iirc, this was quite a while ago), but nobody got it working with utah. If open-source nvidia support didn't get done then when there was no nvidia binary driver, it will *definitely* not get done now. Folks with FreeBSD and NVidias probably will just wait for the binary drivers to work, which I understand will be in the not-too-distant future. Those are just my thoughts. If someone managed to make a working open-source nv dri driver that had even reasonable speeds, I would be very excited and happy. However, probably the place to start wouldn't be reverse-engineering if the target is the DRI, as PIO-based source already exists for at least some of the target cards. -- Eric Anholt http://people.freebsd.org/~anholt/dri/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
