From 1ad24faa116d9f8fab78ad3b81ff6a3625016e50 Mon Sep 17 00:00:00 2001 From: Grigori Goronzy Date: Sun, 9 Jul 2017 03:27:12 +0200 Subject: [PATCH] mesa/marshal: add marshalling for glClearBuffer* MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add async marshalling/unmarshalling for all glClearBuffer variants. These entry points are commonly used in general and Alien Isolation specifically uses glClearBufferiv. Slightly reduces the number of thread synchronizations with glthread in that game.
