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@xxxxxxxxx/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]. Dmitry Osipenko (22): PM / devfreq: tegra30: Change irq type to unsigned int PM / devfreq: tegra30: Keep interrupt disabled while governor is stopped PM / devfreq: tegra30: Handle possible round-rate error PM / devfreq: tegra30: Drop write-barrier PM / devfreq: tegra30: Set up watermarks properly PM / devfreq: tegra30: Tune up boosting thresholds PM / devfreq: tegra30: Use CPUFreq notifier PM / devfreq: tegra30: Move clk-notifier's registration to governor's start PM / devfreq: tegra30: Reset boosting on startup PM / devfreq: tegra30: Don't enable consecutive-down interrupt on startup PM / devfreq: tegra30: Add debug messages PM / devfreq: tegra30: Inline all one-line functions PM / devfreq: tegra30: Constify structs PM / devfreq: tegra30: Ensure that target freq won't overflow PM / devfreq: tegra30: Fix integer overflow on CPU's freq max out PM / devfreq: tegra30: Use kHz units uniformly in the code 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 PM / devfreq: tegra20/30: Add Dmitry as a maintainer MAINTAINERS | 9 + drivers/devfreq/tegra30-devfreq.c | 631 ++++++++++++++++++------- include/trace/events/tegra30_devfreq.h | 105 ++++ 3 files changed, 583 insertions(+), 162 deletions(-) create mode 100644 include/trace/events/tegra30_devfreq.h -- 2.22.0
