From e158c5aa1776372cd751e2c395300a3a6ff0bc9c Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Sun, 17 Jun 2012 09:37:24 -0700 Subject: [PATCH] drm/i915: disable contexts on old HW This got dropped as a result of the last round of comments. I didn't test it on unsupported HW (which this is likely the case). Note that this prevents hw context from blowing up on any pre-gen6 hw.
