The goal is to move some heavy operarions like the memory allocations and heavy computations (multiplications) out of throttle() callback hot path. The new callback is generic enough to handle other imporants update events. It re-uses existing thermal_notify_event definitions. In addition there are some small clean-ups for IPA code. changes: v2: - change callback name to update_tz() and add parameter (Rafael) - added new event to trigger this callback - instance 'weight' update Regards, Lukasz Lukasz Luba (8): thermal: core: Add governor callback for thermal zone change thermal: gov_power_allocator: Refactor check_power_actors() thermal: gov_power_allocator: Move memory allocation out of throttle() thermal: gov_power_allocator: Simplify checks for valid power actor thermal: gov_power_allocator: Refactor checks in divvy_up_power() thermal/sysfs: Update instance->weight under tz lock thermal/sysfs: Update governors when the 'weight' has changed thermal: gov_power_allocator: Support new update callback of weights drivers/thermal/gov_power_allocator.c | 216 ++++++++++++++++++-------- drivers/thermal/thermal_core.c | 13 ++ drivers/thermal/thermal_sysfs.c | 15 ++ include/linux/thermal.h | 6 + 4 files changed, 182 insertions(+), 68 deletions(-) -- 2.25.1
