From 49f08598bf7a52eadebda851a5e8e6fa1dc2e15e Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 3 May 2017 10:39:24 +0100 Subject: [PATCH] drm/i915: Switch the global i915.semaphores check to a local predicate Rather than use a global modparam, we can just check to see if the engine has semaphores configured upon it.
