Subject: [PATCH v3 00/22] More improvements for Tegra30 devfreq driver
Date: Fri, 28 Jun 2019 00:10:53 +0300 [thread overview]
Message-ID: <20190627211115.21138-1-digetx@gmail.com> (raw)
Hello,
This series addresses some additional review comments that were made by
Thierry Reding to [1] and makes several important changes to the driver,
fixing excessive interrupts activity. In the end I'm proposing myself as
a maintainer for the Tegra devfreq drivers.
[1] https://lore.kernel.org/lkml/0fb50eb1-a173-1756-6889-2526a10ac707@gmail.com/T/
Changelog:
v3: Added support for tracepoints, replacing the debug messages.
Fixed few more bugs with the help of tracepoints.
New patches in this version:
PM / devfreq: tegra30: Use tracepoints for debugging
PM / devfreq: tegra30: Optimize CPUFreq notifier
PM / devfreq: tegra30: Optimize upper consecutive watermark selection
PM / devfreq: tegra30: Optimize upper average watermark selection
PM / devfreq: tegra30: Include appropriate header
Some of older patches of this series also got some extra minor polish.
v2: Added more patches that are cleaning driver's code further and
squashing another kHz conversion bug.
The patch "Rework frequency management logic" of the v1 series is now
converted to "Set up watermarks properly" because I found some problems
in the original patch and then realized that there is no need to change
the logic much. So the logic mostly preserved and only got improvements.
The series is based on the today's linux-next (25 Jun) and takes into
account minor changes that MyungJoo Ham made to the already queued
patches from the first batch [1].
