Subject: [PATCH v2 3/4] drm/i915/chv: Set min freq to efficient frequency on chv
Date: Thu, 19 Mar 2015 19:44:28 +0530 [thread overview]
Message-ID: <1426774469-11170-4-git-send-email-deepak.s@linux.intel.com> (raw)
In-Reply-To: <1426774469-11170-1-git-send-email-deepak.s@linux.intel.com>
From: Deepak S <deepak.s@linux.intel.com>
After feedback from the hardware team, now we set the GPU min/idel freq to RPe.
Punit is expecting us to operate GPU between Rpe & Rp0. If we drop the
frequency to RPn, punit is failing to change the input voltage to
minimum :(
v2: Change commit message
