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.

The parsed data is used to build thermal zones and thermal binding parameters. The output data can then be used to deploy thermal policies. 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. For this reason, this patch also removes the 'const' modifier from the .ops field of thermal zone devices.

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: add generic cpufreq cooling implementation This patchset introduces a new generic cooling device based on cpufreq that can be used on non-ACPI platforms. As a proof of concept, we have drivers for the following platforms using this mechanism now: * Samsung Exynos (Exynos4 and Exynos5) in the current patchset. * Freescale i.MX (git://git.linaro.org/people/amitdanielk/linux.git imx6q_thermal) There is a small change in cpufreq cooling registration APIs, so a minor change is needed for Freescale platforms. Brief Description: 1) The generic cooling devices code is placed inside driver/thermal/* as placing inside acpi folder will need un-necessary enabling of acpi code. This code is architecture independent. 2) This patchset adds generic cpu cooling low level implementation through frequency clipping. In future, other cpu related cooling devices may be added here. An ACPI version of this already exists (drivers/acpi/processor_thermal.c) .But this will be useful for platforms like ARM using the generic thermal interface along with the generic cpu cooling devices. The cooling device registration API's return cooling device pointers which can be easily binded with the thermal zone trip points. The important APIs exposed are, a) struct thermal_cooling_device *cpufreq_cooling_register( struct cpumask *clip_cpus) b) void cpufreq_cooling_unregister(struct thermal_cooling_device *cdev) 3) Samsung exynos platform thermal implementation is done using the generic cpu cooling APIs and the new trip type. The temperature sensor driver present in the hwmon folder(registered as hwmon driver) is moved to thermal folder and registered as a thermal driver. A simple data/control flow diagrams is shown below, Core Linux thermal <-----> Exynos thermal interface <----- Temperature Sensor | | \|/ | Cpufreq cooling device <--------------- TODO: *Will send the DT enablement patches later after the driver is merged. This patch: Add support for generic cpu thermal cooling low level implementations using frequency scaling up/down based on the registration parameters. Different cpu related cooling devices can be registered by the user and the binding of these cooling devices to the corresponding trip points can be easily done as the registration APIs return the cooling device pointer. The user of these APIs are responsible for passing clipping frequency . The drivers can also register to recieve notification about any cooling action called.

thermal: add generic cpufreq cooling implementation This patchset introduces a new generic cooling device based on cpufreq that can be used on non-ACPI platforms. As a proof of concept, we have drivers for the following platforms using this mechanism now: * Samsung Exynos (Exynos4 and Exynos5) in the current patchset. * Freescale i.MX (git://git.linaro.org/people/amitdanielk/linux.git imx6q_thermal) There is a small change in cpufreq cooling registration APIs, so a minor change is needed for Freescale platforms. Brief Description: 1) The generic cooling devices code is placed inside driver/thermal/* as placing inside acpi folder will need un-necessary enabling of acpi code. This code is architecture independent. 2) This patchset adds generic cpu cooling low level implementation through frequency clipping. In future, other cpu related cooling devices may be added here. An ACPI version of this already exists (drivers/acpi/processor_thermal.c) .But this will be useful for platforms like ARM using the generic thermal interface along with the generic cpu cooling devices. The cooling device registration API's return cooling device pointers which can be easily binded with the thermal zone trip points. The important APIs exposed are, a) struct thermal_cooling_device *cpufreq_cooling_register( struct cpumask *clip_cpus) b) void cpufreq_cooling_unregister(struct thermal_cooling_device *cdev) 3) Samsung exynos platform thermal implementation is done using the generic cpu cooling APIs and the new trip type.

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: Intel SoC DTS thermal In the Intel SoCs like Bay Trail, there are 2 additional digital temperature sensors(DTS), in addition to the standard DTSs in the core. Also they support 4 programmable thresholds, out of which two can be used by OSPM. These thresholds can be used by OSPM thermal control. Out of these two thresholds, one is used by driver and one user mode can change via thermal sysfs to get notifications on threshold violations. The driver defines one critical trip points, which is set to TJ MAX - offset. The offset can be changed via module parameter (default 5C). Also it uses one of the thresholds to get notification for this temperature violation. This is very important for orderly shutdown as the many of these devices don't have ACPI thermal zone, and expects that there is some other thermal control mechanism present in OSPM. When a Linux distro is used without additional specialized thermal control program, BIOS can do force shutdown when thermals are not under control.

thermal: intel Quark SoC X1000 DTS thermal driver In Intel Quark SoC X1000, there is one on-die digital temperature sensor(DTS). The DTS offers both hot & critical trip points. However, in current distribution of UEFI BIOS for Quark platform, only critical trip point is configured to be 105 degree Celsius (based on Quark SW ver1.0.1 and hot trip point is not used due to lack of IRQ. There is no active cooling device for Quark SoC, so Quark SoC thermal management logic expects Linux distro to orderly power-off when temperature of the DTS exceeds the configured critical trip point. Kernel param "polling_delay" in milliseconds is used to control the frequency the DTS temperature is read by thermal framework. It defaults to 2-second. To change it, use kernel boot param "intel_quark_dts_thermal.polling_delay=X". User interacts with Quark SoC DTS thermal driver through sysfs via: /sys/class/thermal/thermal_zone0/ For example: - to read DTS temperature $ cat temp - to read critical trip point $ cat trip_point_0_temp - to read trip point type $ cat trip_point_0_type - to emulate temperature raise to test orderly shutdown by Linux distro $ echo 105 > emul_temp Tested-by: Bryan O'Donoghue <pure.logic@nexus-software.ie> Signed-off-by: Ong Boon Leong <boon.leong.ong@intel.com> Reviewed-by: Bryan O'Donoghue <pure.logic@nexus-software.ie> Reviewed-by: Kweh, Hock Leong <hock.leong.kweh@intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>

thermal: Add QPNP PMIC temperature alarm driver Add support for the temperature alarm peripheral found inside Qualcomm plug-and-play (QPNP) PMIC chips. The temperature alarm peripheral outputs a pulse on an interrupt line whenever the thermal over temperature stage value changes. Register a thermal sensor. The temperature reported by this thermal sensor device should reflect the actual PMIC die temperature if an ADC is present on the given PMIC. If no ADC is present, then the reported temperature should be estimated from the over temperature stage value. Cc: David Collins <collinsd@codeaurora.org> Signed-off-by: Ivan T.

Revert "thermal: qcom_spmi: allow compile test" This just caused build errors: warning: (QCOM_SPMI_TEMP_ALARM) selects REGMAP_SPMI which has unmet direct dependencies (SPMI) drivers/built-in.o: In function `regmap_spmi_ext_gather_write': :(.text+0x609b0): undefined reference to `spmi_ext_register_write' :(.text+0x609f0): undefined reference to `spmi_ext_register_writel' While it's generally a good idea to allow compile testing, in this case, it just doesn't work, so reverting the patch that introduced the compile-test variant seems the most appropriate solution. Note that SPMI also has a 'depends on ARCH_QCOM || COMPILE_TEST' statement, so we should be able to enable SPMI on all architectures for compile testing already.

This enables a thermal sysfs driver for Qualcomm plug-and-play (QPNP)
PMIC devices. It shows up in sysfs as a thermal sensor with multiple
trip points. The temperature reported by the thermal sensor reflects the
real time die temperature if an ADC is present or an estimate of the
temperature based upon the over temperature stage value.
thermal: generic-adc: Add ADC based thermal sensor driver In some of platform, thermal sensors like NCT thermistors are connected to the one of ADC channel. The temperature is read by reading the voltage across the sensor resistance via ADC. Lookup table for ADC read value to temperature is referred to get temperature. ADC is read via IIO framework. Add support for thermal sensor driver which read the voltage across sensor resistance from ADC through IIO framework.

thermal: qcom: tsens: Add a skeletal TSENS drivers TSENS is Qualcomms' thermal temperature sensor device. It supports reading temperatures from multiple thermal sensors present on various QCOM SoCs. Calibration data is generally read from a non-volatile memory (eeprom) device. Add a skeleton driver with all the necessary abstractions so a variety of qcom device families which support TSENS can add driver extensions. Also add the required device tree bindings which can be used to describe the TSENS device in DT.
