From e8b2c3c47a53348aebbbeb5322e32937df958793 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 1 Mar 2011 19:22:52 +0000 Subject: [PATCH] drm/i915: Re-enable GPU semaphores for SandyBridge mobile This seems to be running stably on my test laptop, so hopefully the reported hangs where just symptoms of other bugs.
