The fake buffer object bits were removed only leaving full TTM support. We don't have TTM support in the kernel yet and my kernel patch relies on the fake buffer object code to function. > P.S. libdrm was update to 2.4.17, so I'll update... That is the issue, if we update libdrm then we lose drm support for nouveau. The only immediate option that I see is to repo-copy libdrm to keep 2.4.12 for nouveau, but that leads to dependency nightmares... robert. -- Robert Noland <rnoland@FreeBSD.org> FreeBSD
