We wouldn't have to. It would just be internal to the way the driver stores the texture on the hardware... kind of like how core Mesa doesn't know anything about tiling formats, etc. Either way, I'd want to be 100% sure it would work before messing with it. Someone with reverse engineering skills would have to see if the blob does it that way first. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
