thermal: exynos: Propagate error value from tmu_read()

2018-04-27T13:17:30+00:00

tmu_read() in case of Exynos4210 might return error for out of bound values. Current code ignores such value, what leads to reporting critical temperature value. Add proper error code propagation to exynos_get_temp() function.

thermal: exynos: Reading temperature makes sense only when TMU is turned on

2018-04-27T13:17:30+00:00

When thermal sensor is not yet enabled, reading temperature might return random value. This might even result in stopping system booting when such temperature is higher than the critical value. Fix this by checking if TMU has been actually enabled before reading the temperature. This change fixes booting of Exynos4210-based board with TMU enabled (for example Samsung Trats board), which was broken since v4.4 kernel release.

thermal: int3403_thermal: Fix NULL pointer deref on module load / probe

2018-04-24T12:50:43+00:00

Starting with kernel 4.17 thermal_cooling_device_register() will call the get_max_state() op during register. Since we deref priv->priv in int3403_get_max_state() this means we must set priv->priv before calling thermal_cooling_device_register(). Signed-off-by: Hans de Goede Signed-off-by: Zhang Rui

thermal: Add cooling device's statistics in sysfs

2018-04-02T13:49:01+00:00

This extends the sysfs interface for thermal cooling devices and exposes some pretty useful statistics. These statistics have proven to be quite useful specially while doing benchmarks related to the task scheduler, where we want to make sure that nothing has disrupted the test, specially the cooling device which may have put constraints on the CPUs. The information exposed here tells us to what extent the CPUs were constrained by the thermal framework. The write-only "reset" file is used to reset the statistics. The read-only "time_in_state_ms" file shows the time (in msec) spent by the device in the respective cooling states, and it prints one line per cooling state. The read-only "total_trans" file shows single positive integer value showing the total number of cooling state transitions the device has gone through since the time the cooling device is registered or the time when statistics were reset last. The read-only "trans_table" file shows a two dimensional matrix, where an entry (row i, column j) represents the number of transitions from State_i to State_j. This is how the directory structure looks like for a single cooling device: $ ls -R /sys/class/thermal/cooling_device0/ /sys/class/thermal/cooling_device0/: cur_state max_state power stats subsystem type uevent /sys/class/thermal/cooling_device0/power: autosuspend_delay_ms runtime_active_time runtime_suspended_time control runtime_status /sys/class/thermal/cooling_device0/stats: reset time_in_state_ms total_trans trans_table This is tested on ARM 64-bit Hisilicon hikey620 board running Ubuntu and ARM 64-bit Hisilicon hikey960 board running Android.

thermal: imx: Fix race condition in imx_thermal_probe()

2018-03-14T07:14:40+00:00

When device boots with T > T_trip_1 and requests interrupt, the race condition takes place. The interrupt comes before THERMAL_DEVICE_ENABLED is set. This leads to an attempt to reading sensor value from irq and disabling the sensor, based on the data->mode field, which expected to be THERMAL_DEVICE_ENABLED, but still stays as THERMAL_DEVICE_DISABLED. Afher this issue sensor is never re-enabled, as the driver state is wrong. Fix this problem by setting the 'data' members prior to requesting the interrupts.

Pull driver core updates from Greg KH: "Here is the set of "big" driver core patches for 4.16-rc1. The majority of the work here is in the firmware subsystem, with reworks to try to attempt to make the code easier to handle in the long run, but no functional change. There's also some tree-wide sysfs attribute fixups with lots of acks from the various subsystem maintainers, as well as a handful of other normal fixes and changes. And finally, some license cleanups for the driver core and sysfs code.
