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 -- To unsubscribe from this list: send the line "unsubscribe linux-fbdev" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
