The AGPSize is just to say how much of the aperture to allocate and bind for use. It turns out that 8MB is all that's really necessary, due to poor or nonexistent use of AGP textures, so that basically what gets used in AGP are the 3MB of vertex/indirect/ring buffers. I wasn't previously aware of any 64-bit issues in the Radeon/R200 DRI (and some have used these on 64-bit machines before), but to me that seems like the most likely reason to find bad command buffers. -- Eric Anholt eta@lclark.edu http://people.freebsd.org/~anholt/ anholt@FreeBSD.org
