From 71386ef9008817feebd863e46d8711ebe9e7cbbb Mon Sep 17 00:00:00 2001 From: Oscar Mateo Date: Thu, 24 Jul 2014 17:04:44 +0100 Subject: [PATCH] drm/i915/bdw: Disable semaphores for Execlists Up until recently, semaphores weren't enabled in BDW so we didn't care about them. But then Rodrigo came and enabled them: commit 521e62e49a42661a4ee0102644517dbe2f100a23 Author: Rodrigo Vivi drm/i915: Enable semaphores on BDW So now we have to explicitly disable them for Execlists until both features play nicely.
