From 549f7365820a212a1cfd0871d377b1ad0d1e5723 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 19 Oct 2010 11:19:32 +0100 Subject: [PATCH] drm/i915: Enable SandyBridge blitter ring Based on an original patch by Zhenyu Wang, this initializes the BLT ring for SandyBridge and enables support for user execbuffers.
