Not sure about that in gernal; unless I'm missing something, it would require moving BOs from TT to VRAM for CPU mappings, and I don't think that's a good idea. It might be useful for scanout buffers though. Maybe another object creation parameter which specifies the CPU byte swapping vs. the GPU byte order (little endian) could work, then we could use surface registers for VRAM mappings or GPU byte swapping bits for GPU access to/from TT. -- Earthling Michel Dänzer | http://www.vmware.com Libre software enthusiast | Debian, X and DRI developer ------------------------------------------------------------------------------ -- _______________________________________________ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel
