Subject: [PATCH v5 06/20] PM / devfreq: tegra30: Tune up boosting thresholds
Date: Tue, 30 Jul 2019 19:22:22 +0300 [thread overview]
Message-ID: <20190730162236.6063-7-digetx@gmail.com> (raw)
In-Reply-To: <20190730162236.6063-1-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.
