From 7299e82fa444c86f4c5e22593424715454182e9a Mon Sep 17 00:00:00 2001 From: Grigori Goronzy Date: Thu, 29 Jun 2017 03:24:15 +0200 Subject: dri: Add KHR_no_error DRI extension MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This basic extension allows usage of the __DRI_CTX_FLAG_NO_ERROR flag. This includes support code for classic Mesa drivers to switch on the no-error mode if the flag is set. v2: Move to common DRI code.
