Thanks, can this allocation be done to any part of the video mem? I mean are there some areas that will never be written by the new ttm allocator, such as the VESA framebuffer zone, that I suppose is at the very beginning of the video memory. Well, let's see if I manage to understand the TTM code ;-) >Most GPU memory is interleaved so if one chip is broken you can't just >ignore it linearly, its probably possible to reconfigure the memory > controller but I can't imaging a 256-bit memory bus working at 192-bit so > well, and you'd lose more than one RAM chip. Well, I think this fact is illustrated by tha way the broken zone shows up : only one pixel over eight at 24bpp, one over sixteen at 16bpp, etc. But the affected pixels are really just a few, so I can hope to get it working. Thanks for both answers. José _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
