From b04cf529f2e7bab6be22410d4be293aa5e650b03 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Mon, 26 Feb 2018 23:41:33 -0800 Subject: [PATCH] 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.
