I thought CPU access to framebuffers is atypical nowadays. But not entirely forgotten. It's the first, and sometimes, last thing a client wires up. (Just yesterday mesa gained a patch for yet another access path. Great.) I also think it is of wider utility for the when the buffer gets reused or new views. Your argument applies better to the wider aspect of the futility of keeping caches around that may never be reused. And that is worth improving, even more so if we can measure an impact. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
