Author: Kenneth Graunke <kenn...@whitecape.org> Date: Mon Feb 26 23:41:33 2018 -0800 i965: Mark upload buffers with MAP_ASYNC and MAP_PERSISTENT. This should have no practical impact. For the default uploader, we don't really care, but for others, we may want to append more data as the GPU is reading existing data, which means we need async and persistent flags.
