From 0d925ea02310fa5b99988bfe7942aa010f2a4723 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Wed, 4 Nov 2015 23:20:11 +0200 Subject: [PATCH] drm/i915: Wrap context LRI init in a macro MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit We set up a load of LRIs in the logical ring context. Wrap that stuff in a macro to avoid typos with position of each reg/value pair in the context. This also makes it easier to make the register defines type safe.
