From 8a59f2f26fb7bb036ad524cdec668716664d2a82 Mon Sep 17 00:00:00 2001 From: Neil Roberts Date: Fri, 7 Nov 2014 18:20:17 +0000 Subject: [PATCH] i965: Store the command parser version number in intel_screen In order to detect whether the predicate source registers can be used in a later patch we will need to know the version number for the command parser. This patch just adds a member to intel_screen and does an ioctl to get the version.
