Subject: [PATCH 08/15] drm/i915: Move execlists defines from .c to .h
Date: Mon, 15 Jun 2015 19:36:26 +0100	[thread overview]
Message-ID: <1434393394-21002-9-git-send-email-david.s.gordon@intel.com> (raw)
In-Reply-To: <1434393394-21002-1-git-send-email-david.s.gordon@intel.com>

From: "Michael H. Nguyen" <michael.h.nguyen@intel.com>

Move defines from intel_lrc.c to i915_reg.h so they are accessible
to the GuC submission code; and expose a previously static function
in the execlist code which will also be required for GuC submission.

Issue: VIZ-4884
