From 65e5ecb066fe54c13c8445d6acfdcdf149ad5df9 Mon Sep 17 00:00:00 2001 From: Yuanhan Liu Date: Mon, 8 Nov 2010 09:56:37 +0000 Subject: [PATCH] drm/i915: Add untraced register read/write interface This will be used later to hide the frequently written registers from debug traces in order to increase the signal-to-noise.
