2019-05-06thermal/drivers/core: Remove the module Kconfig's optionDaniel Lezcano1-2/+2
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.

2019-01-29thermal: cpu_cooling: Require thermal core to be compiled inAmit Kucheria1-0/+1
The CPU cooling driver (cpu_cooling.c) allows the platform's cpufreq driver to register as a cooling device and cool down the platform by throttling the CPU frequency. In order to be able to auto-register a cpufreq driver as a cooling device from the cpufreq core, we need access to code inside cpu_cooling.c which, in turn, accesses code inside thermal core. CPU_FREQ is a bool while THERMAL is tristate. In some configurations (e.g. allmodconfig), CONFIG_THERMAL ends up as a module while CONFIG_CPU_FREQ is compiled in. This leads to following error: drivers/cpufreq/cpufreq.o: In function `cpufreq_offline': cpufreq.c:(.text+0x407c): undefined reference to `cpufreq_cooling_unregister' drivers/cpufreq/cpufreq.o: In function `cpufreq_online': cpufreq.c:(.text+0x70c0): undefined reference to `of_cpufreq_cooling_register' Given that platforms using CPU_THERMAL usually want it compiled-in so it is available early in boot, make CPU_THERMAL depend on THERMAL being compiled-in instead of allowing it to be a module. As a result of this change, get rid of the ugly (!CPU_THERMAL || THERMAL) dependency in all cpufreq drivers using CPU_THERMAL. Suggested-by: Rafael J.

2018-07-26Thermal: Intel SoC DTS: Translate IO-APIC GSI number to linux irq numberHans de Goede1-1/+1
The Intel SoC DTS uses a hardcoded GSI number, before this commit it was passing it to request_irq as if it were a linux irq number, but there is no 1:1 mapping so in essence it was requesting a random interrupt. Besides this causing the DTS driver to not actually get an interrupt if the thermal thresholds are exceeded this also is causing an interrupt conflict on some devices since the linux irq 86 which is being requested is already in use, leading to oopses like this: genirq: Flags mismatch irq 86. 00002001 (soc_dts) vs. 00000083 (volume_down) CPU: 0 PID: 601 Comm: systemd-udevd Tainted: G C OE 4.17.0-rc6+ #45 Hardware name: Insyde i86/Type2 - Board Product Name, BIOS CHUWI.D86JLBNR03 01/14/2015 Call Trace: dump_stack+0x5c/0x80 __setup_irq.cold.50+0x4e/0xac ? request_threaded_irq+0xad/0x160 request_threaded_irq+0xf5/0x160 ? 0xffffffffc0a93000 intel_soc_thermal_init+0x74/0x1000 [intel_soc_dts_thermal] This commit makes the intel_soc_dts_thermal.c code call acpi_register_gsi() to translate the hardcoded IO-APIC GSI number (86) to a linux irq, so that the dts code uses the right interrupt and we no longer get an oops about an irq conflict.

2018-04-02thermal: Add cooling device's statistics in sysfsViresh Kumar1-0/+7
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.

2017-05-05thermal: core: Add a back up thermal shutdown mechanismKeerthy1-0/+17
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.

2017-04-27mfd: intel_soc_pmic: Fix a mess with compilation unitsAndy Shevchenko1-1/+1
Crystal Cove and Whiskey Cove are two different PMICs which are installed on Intel Atom SoC based platforms. Moreover there are two independent drivers that by some reason were supposed (*) to get into one kernel module. Fix the mess by clarifying Kconfig option for Crystal Cove and split Whiskey Cove out of it. (*) It looks like the configuration was never tested with INTEL_SOC_PMIC=n. The line in Makefile is actually wrong. Cc: "Rafael J.

2017-04-06thermal: da9062/61: Thermal junction temperature monitoring driverSteve Twiss1-0/+10
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.

2017-03-16cpufreq: dbx500: Manage cooling device from cpufreq driverViresh Kumar1-12/+0
The best place to register the CPU cooling device is from the cpufreq driver as we would know if all the resources are already available or not. That's what is done for the cpufreq-dt.c driver as well. The cpu-cooling driver for dbx500 platform was just (un)registering with the thermal framework and that can be handled easily by the cpufreq driver as well and in proper sequence as well. Get rid of the cooling driver and its its users and manage everything from the cpufreq driver instead.

The thermal driver is standalone driver which is used to enable thermal sensors, so it can be used with any cooling device and should not bind with CPU cooling device driver. This original patch is suggested by Amit Kucheria; so it's to polish the dependency in Kconfig, and remove the dependency with CPU_THERMAL.
