From 626ad6f37de1620e9ccd6b28f1743ee959b582c6 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 26 Feb 2015 21:10:27 +0530 Subject: [PATCH] drm/i915: Add media rc6 residency file to sysfs MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit On VLV/CHV the media well rc6 residency gets reported separately from the render well, so add another file to sysfs so that we can report the residency to the user.
