Its behavior won't be optimal, it would be the best possible with the data provided. Changes since v5: - Rebased on top of v4.3-rc1 Changes since v4: - Fix crash when a thermal zone with no trip points has no get_trip_point_temp(). Reported by Daniel Kurtz. - s/estimate_controller_constants()/estimate_pid_constants()/g Changes since v3: - Don't hardcode a value for sustainable power and re-estimate the PID controllers every time if no sustainable power is given as suggested by Eduardo Valentin. - power_actor_get_min_power() moved to a patch of its own. Changes since v2: - Typos suggested by Daniel Kurtz Changes since v1: - Let the power allocator governor operate if the thermal zone doesn't have tzp as suggested by Chung-yih Wang Javi Merino (5): thermal: Add a function to get the minimum power thermal: power_allocator: relax the requirement of a sustainable_power in tzp thermal: power_allocator: relax the requirement of two passive trip points thermal: power_allocator: don't require tzp to be present for the thermal zone thermal: power_allocator: exit early if there are no cooling devices Documentation/thermal/power_allocator.txt | 2 +- drivers/thermal/power_allocator.c | 243 ++++++++++++++++++++++-------- drivers/thermal/thermal_core.c | 28 ++++ include/linux/thermal.h | 6 + 4 files changed, 214 insertions(+), 65 deletions(-) -- 1.9.1
