Subject: [PATCH v4 06/24] PM / devfreq: tegra30: Tune up boosting thresholds
Date: Mon,  8 Jul 2019 01:32:45 +0300
Message-ID: <20190707223303.6755-7-digetx@gmail.com> (raw)
In-Reply-To: <20190707223303.6755-1-digetx@gmail.com>

Now that average-sustain coefficient / multiplier is gone, it won't hurt
to re-tune the boosting thresholds to get a bit harder boosting for MCALL
clients, resulting in a more reactive governing in a case of multimedia
applications usage like 3d / video.
