thermal/drivers/core: Remove the module Kconfig's option The module support for the thermal subsystem makes little sense: - some subsystems relying on it are not modules, thus forcing the framework to be compiled in - it is compiled in for almost every configs, the remaining ones are a few platforms where I don't see why we can not switch the thermal to 'y'. The drivers can stay in tristate. - platforms need the thermal to be ready as soon as possible at boot time in order to mitigate Usually the subsystems framework are compiled-in and the plugs are as module. Remove the module option. The removal of the module related dead code will come after this patch gets in or is acked.

thermal: Add cooling device's statistics in sysfs 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 <i,j> (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: core: Add a back up thermal shutdown mechanism orderly_poweroff is triggered when a graceful shutdown of system is desired. This may be used in many critical states of the kernel such as when subsystems detects conditions such as critical temperature conditions. However, in certain conditions in system boot up sequences like those in the middle of driver probes being initiated, userspace will be unable to power off the system in a clean manner and leaves the system in a critical state. In cases like these, the /sbin/poweroff will return success (having forked off to attempt powering off the system. However, the system overall will fail to completely poweroff (since other modules will be probed) and the system is still functional with no userspace (since that would have shut itself off). However, there is no clean way of detecting such failure of userspace powering off the system. In such scenarios, it is necessary for a backup workqueue to be able to force a shutdown of the system when orderly shutdown is not successful after a configurable time period.

Thermal subsystem will issue a graceful shutdown when
critical temperatures are reached using orderly_poweroff(). In
case of failure of an orderly_poweroff(), the thermal emergency
poweroff kicks in after a delay has elapsed and shuts down the system.
This config is number of milliseconds to delay before emergency
poweroff kicks in. Similarly to the critical trip point,
the delay should be carefully profiled so as to give adequate
time for orderly_poweroff() to finish on regular execution.
If set to 0 emergency poweroff will not be supported.
In doubt, leave as 0.

This patch adds also documentation regarding this API and how to define tree nodes to use this infrastructure. Note that, in order to be able to have control on the sensor registration on the DT thermal zone, it was required to allow changing the thermal zone .get_temp callback.

thermal: introduce the Power Allocator governor The power allocator governor is a thermal governor that controls system and device power allocation to control temperature. Conceptually, the implementation divides the sustainable power of a thermal zone among all the heat sources in that zone. This governor relies on "power actors", entities that represent heat sources. They can report current and maximum power consumption and can set a given maximum power consumption, usually via a cooling device. The governor uses a Proportional Integral Derivative (PID) controller driven by the temperature of the thermal zone. The output of the controller is a power budget that is then allocated to each power actor that can have bearing on the temperature we are trying to control. It decides how much power to give each cooling device based on the performance they are requesting. The PID controller ensures that the total power budget does not exceed the control temperature.

thermal: introduce the Power Allocator governor The power allocator governor is a thermal governor that controls system and device power allocation to control temperature. Conceptually, the implementation divides the sustainable power of a thermal zone among all the heat sources in that zone. This governor relies on "power actors", entities that represent heat sources. They can report current and maximum power consumption and can set a given maximum power consumption, usually via a cooling device. The governor uses a Proportional Integral Derivative (PID) controller driven by the temperature of the thermal zone. The output of the controller is a power budget that is then allocated to each power actor that can have bearing on the temperature we are trying to control. It decides how much power to give each cooling device based on the performance they are requesting. The PID controller ensures that the total power budget does not exceed the control temperature.

thermal: cpu_cooling: Migrate to using the EM framework The newly introduced Energy Model framework manages power cost tables in a generic way. Moreover, it supports several types of models since the tables can come from DT or firmware (through SCMI) for example. On the other hand, the cpu_cooling subsystem manages its own power cost tables using only DT data. In order to avoid the duplication of data in the kernel, and in order to enable IPA with EMs coming from more than just DT, remove the private tables from cpu_cooling.c and migrate it to using the centralized EM framework. Doing so should have no visible functional impact for existing users of IPA since: - recent extenstions to the the PM_OPP infrastructure enable the registration of EMs in PM_EM using the DT property used by IPA; - the existing upstream cpufreq drivers marked with the 'CPUFREQ_IS_COOLING_DEV' flag all use the aforementioned PM_OPP infrastructure, which means they all support PM_EM. The only two exceptions are qoriq-cpufreq which doesn't in fact use an EM and scmi-cpufreq which doesn't use DT for power costs. For existing users of cpu_cooling, PM_EM tables will contain the exact same power values that IPA used to compute on its own until now. The only new dependency for them is to compile in CONFIG_ENERGY_MODEL. The case where the thermal subsystem is used without an Energy Model (cpufreq_cooling_ops) is handled by looking directly at CPUFreq's frequency table which is already a dependency for cpu_cooling.c anyway. Since the thermal framework expects the cooling states in a particular order, bail out whenever the CPUFreq table is unsorted, since that is fairly uncommon in general, and there are currently no users of cpu_cooling for this use-case.

thermal/drivers/cpu_cooling: Introduce the cpu idle cooling driver The cpu idle cooling device offers a new method to cool down a CPU by injecting idle cycles at runtime. It has some similarities with the intel power clamp driver but it is actually designed to be more generic and relying on the idle injection powercap framework. The idle injection duration is fixed while the running duration is variable. That allows to have control on the device reactivity for the user experience. An idle state powering down the CPU or the cluster will allow to drop the static leakage, thus restoring the heat capacity of the SoC. It can be set with a trip point between the hot and the critical points, giving the opportunity to prevent a hard reset of the system when the cpufreq cooling fails to cool down the CPU. With more sophisticated boards having a per core sensor, the idle cooling device allows to cool down a single core without throttling the compute capacity of several cpus belonging to the same clock line, so it could be used in collaboration with the cpufreq cooling device.

thermal: introduce clock cooling device This patch introduces a new thermal cooling device based on common clock framework. The original motivation to write this cooling device is to be able to cool down thermal zones using clocks that feed co-processors, such as GPUs, DSPs, Image Processing Co-processors, etc. But it is written in a way that it can be used on top of any clock. The implementation is pretty straight forward. The code creates a thermal cooling device based on a pair of a struct device and a clock name. The struct device is assumed to be usable by the OPP layer. The OPP layer is used as source of the list of possible frequencies. The (cpufreq) frequency table is then used as a map from frequencies to cooling states. Cooling states are indexes to the frequency table. The logic sits on top of common clock framework, specifically on clock pre notifications. Any PRE_RATE_CHANGE is hijacked, and the transition is only allowed when the new rate is within the thermal limit (cooling state -> freq). When a thermal cooling device state transition is requested, the clock is also checked to verify if the current clock rate is within the new thermal limit.

thermal: da9062/61: Thermal junction temperature monitoring driver Add junction temperature monitoring supervisor device driver, compatible with the DA9062 and DA9061 PMICs. A MODULE_DEVICE_TABLE() macro is added. If the PMIC's internal junction temperature rises above T_WARN (125 degC) an interrupt is issued. This T_WARN level is defined as the THERMAL_TRIP_HOT trip-wire inside the device driver. The thermal triggering mechanism is interrupt based and happens when the temperature rises above a given threshold level. The component cannot return an exact temperature, it only has knowledge if the temperature is above or below a given threshold value. A status bit must be polled to detect when the temperature falls below that threshold level again. A kernel work queue is configured to repeatedly poll and detect when the temperature falls below this trip-wire, between 1 and 10 second intervals (defaulting at 3 seconds). This scheme is provided as an example. It would be expected that any final implementation will also include a notify() function and any of these settings could be altered to match the application where appropriate. When over-temperature is reached, the interrupt from the DA9061/2 will be repeatedly triggered. The IRQ is therefore disabled when the first over-temperature event happens and the status bit is polled using a work-queue until it becomes false. This strategy is designed to allow the periodic transmission of uevents (HOT trip point) as the first level of temperature supervision method. It is intended for non-invasive temperature control, where the necessary measures for cooling the system down are left to the host software. Once the temperature falls again, the IRQ is re-enabled so a new critical over-temperature event can be detected.

thermal: Add Mediatek thermal controller support This adds support for the Mediatek thermal controller found on MT8173 and likely other SoCs. The controller is a bit special. It does not have its own ADC, instead it controls the on-SoC AUXADC via AHB bus accesses. For this reason we need the physical address of the AUXADC. Also it controls a mux using AHB bus accesses, so we need the APMIXEDSYS physical address aswell.

One is located close to the DDR controller and the other one is located close to the PLLs (between the CPU and GPU). The calibration data for each of the thermal sensors instance is stored in a different location within the AO region. Implement reading the temperature from each thermal sensor.
