Subject: [PATCH 0/4] HSW PM - RC6 fixes, clean up and split
Date: Mon, 25 Mar 2013 17:55:48 -0300 [thread overview]
Message-ID: <1364244952-25996-1-git-send-email-rodrigo.vivi@gmail.com> (raw)
This series fixes a RC6 bug at HSW that can impact its performance.
At my fiurst attempt I noticed more than 1W saved, but I didn't measured this lates series yet.
Also there are 2 clean ups patches that removes unecessary registers and bits set for HSW.
The latest patch is optional. It splits hsw_enable_rps to make it more clean since the gen6_enable_rps was becoming a mess full of IS_HASWELL and probably becoming worse with new upcoming platforms.
Rodrigo Vivi (4):
drm/i915: HSW PM Frequency bits fix
drm/i915: HSW PM Cleaning - Removing unecessary register/bits set.
drm/i915: HSW PM - removing pcode read/write
