That is probably true for anything pci-ish, because those devices are optimized for memory writes and reads are horribly slow. So you surely want avoid device memory reads and shadowing is a effective way to do this. On arm hardware the tradeoff may look quite different, the cpus are relatively slow and I think most arm gpus don't have dedicated device memory ... cheers, Gerd _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
