[Intel-gfx] [PATCH 2/5] drm/i915: Promote IS_BROADWELL to a simple macro

Tvrtko Ursulin tvrtko.ursulin at linux.intel.com
Mon May 9 13:00:05 UTC 2016


From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>

If we allow it a dedicated flag in dev_priv we enable the
compiler to nicely optimize conditions like IS_HASSWELL ||
IS_BROADWELL.
