Subject: [PATCH 15/26] drm/i915/slpc: Notification of Refresh Rate change
Date: Tue, 8 Mar 2016 16:34:18 -0800 [thread overview]
Message-ID: <1457483669-155235-16-git-send-email-tom.orourke@intel.com> (raw)
In-Reply-To: <1457483669-155235-1-git-send-email-tom.orourke@intel.com>
From: Sagar Arun Kamble <sagar.a.kamble@intel.com>
This patch will inform GuC SLPC about changes in the refresh rate
due to Seamless DRRS. Refresh rate changes due to Static DRRS will
be notified via commit path.
v2: Rebased on previous changed patch and printed error message if
H2G action fails.
v2(torourke): Updates suggested by Paulo: replace HAS_SLPC with
intel_slpc_active. return void instead of ignored error code.
