Author: Alyssa Rosenzweig <[email protected]> Date: Fri Oct 28 22:36:52 2022 -0400 softpipe: Advertise PIPE_CAP_BUFFER_MAP_PERSISTENT_COHERENT It's a software rasterizer, all buffers are necessarily persistent and coherent. There are no staging buffers in transfer_map and no sync/flush operations, so this is trivial.
