Sun, 11 May 2025 20:49:55 +0200

thermal/drivers: Add support for Airoha EN7581 thermal sensorAdd support for Airoha EN7581 thermal sensor. This provide support forreading the CPU or SoC Package sensor and to setup trip points for hotand critical condition. An interrupt is fired to react on this anddoesn't require passive poll to read the temperature.The thermal regs provide a way to read the ADC value from an externalregister placed in the Chip SCU regs. Monitor will read this value andfire an interrupt if the trip condition configured is reached.The Thermal Trip and Interrupt logic is conceptually similar to MediatekLVTS Thermal but differ in register mapping and actual function/bugworkaround. The implementation only share some register names but fromfunctionality observation it's very different and used only for thebasic function of periodically poll the temp and trip the interrupt.Signed-off-by: Christian Marangi Link: https://lore.kernel.org/r/20250511185003.3754495-2-ansuelsmth@gmail.comSigned-off-by: Daniel Lezcano List of files: /linux/drivers/thermal/Makefile

Mon, 23 Sep 2024 11:59:57 +0200

thermal: core: Add user thresholds supportThe user thresholds mechanism is a way to have the userspace to tellthe thermal framework to send a notification when a temperature limitis crossed. There is no id, no hysteresis, just the temperature andthe direction of the limit crossing. That means we can be notifiedwhen a threshold is crossed the way up only, or the way down only orboth ways. That allows to create hysteresis values if it is needed.A threshold can be added, deleted or flushed. The latter means allthresholds belonging to a thermal zone will be deleted.When a threshold is added: - if the same threshold (temperature and direction) exists, an error is returned - if a threshold is specified with the same temperature but a different direction, the specified direction is added - if there is no threshold with the same temperature then it is createdWhen a threshold is deleted: - if the same threshold (temperature and direction) exists, it is deleted - if a threshold is specified with the same temperature but a different direction, the specified direction is removed - if there is no threshold with the same temperature, then an error is returnedWhen the threshold are flushed: - All thresholds related to a thermal zone are deletedWhen a threshold is crossed: - the userspace does not need to know which threshold(s) have been crossed, it will be notified with the current temperature and the previous temperature - if multiple thresholds have been crossed between two updates only one notification will be send to the userspace, it is pointless to send a notification per thresholds crossed as the userspace can handle that easily when it has the temperature delta informationSigned-off-by: Daniel Lezcano Link: https://patch.msgid.link/20240923100005.2532430-2-daniel.lezcano@linaro.org[ rjw: Subject edit, use BIT(0) and BIT(1) in symbol definitions ]Signed-off-by: Rafael J.

thermal: Introduce a debugfs-based testing facilityIntroduce a facility allowing the thermal core functionality to beexercised in a controlled way in order to verify its behavior, withoutaffecting its regular users noticeably.It is based on the idea of preparing thermal zone templates along withtheir trip points by writing to files in debugfs. When ready, thosetemplates can be used for registering test thermal zones with thethermal core.The temperature of a test thermal zone created this way can be adjustedvia debugfs, which also triggers a __thermal_zone_device_update() callfor it. By manipulating the temperature of a test thermal zone, one cancheck if the thermal core reacts to the changes of it as expected.Signed-off-by: Rafael J.

Tue, 09 Jan 2024 10:41:11 +0100

thermal/debugfs: Add thermal cooling device debugfs informationThe thermal framework does not have any debug information except asysfs stat which is a bit controversial. This one allocates big chunksof memory for every cooling devices with a high number of states andcould represent on some systems in production several megabytes ofmemory for just a portion of it. As the sysfs is limited to a pagesize, the output is not exploitable with large data array and getstruncated.The patch provides the same information than sysfs except thetransitions are dynamically allocated, thus they won't show moreevents than the ones which actually occurred. There is no longer asize limitation and it opens the field for more debugging informationwhere the debugfs is designed for, not sysfs.The thermal debugfs directory structure tries to stay consistent withthe sysfs one but in a very simplified way:thermal/ -- cooling_devices |-- 0 | |-- clear | |-- time_in_state_ms | |-- total_trans | `-- trans_table |-- 1 | |-- clear | |-- time_in_state_ms | |-- total_trans | `-- trans_table |-- 2 | |-- clear | |-- time_in_state_ms | |-- total_trans | `-- trans_table |-- 3 | |-- clear | |-- time_in_state_ms | |-- total_trans | `-- trans_table `-- 4 |-- clear |-- time_in_state_ms |-- total_trans `-- trans_tableThe content of the files in the cooling devices directory is the sameas the sysfs one except for the trans_table which has the followingformat:Transition Hits1->0 2460->1 2462->1 6321->2 6323->2 982->3 98Signed-off-by: Daniel Lezcano [ rjw: White space fixups, rebase ]Signed-off-by: Rafael J.

Each of these functions basicallyevaluates a specific ACPI object, checks if the value produced by itis reasonable and returns it (or THERMAL_TEMP_INVALID if anythingfails).It made sense to hold it in drivers/thermal/ so long as it was only usedby the code in that directory, but since it is also going to be used bythe ACPI thermal driver located in drivers/acpi/, move it to the latterin order to keep the code related to evaluating ACPI objects defined inthe specification proper together.No intentional functional impact.Signed-off-by: Rafael J.

Mon, 23 Jan 2023 16:27:56 +0100

thermal/core: Move the thermal trip code to a dedicated fileThe thermal_core.c files contains a lot of functions handlingdifferent thermal components like the governors, the trip points, thecooling device, the OF cooling device, etc ...This organization does not help to migrate to a more sane code wherethere is a better self-encapsulation as all the components' internalscan be directly accessed from a single file.For the sake of clarity, let's move the thermal trip points code in adedicated thermal_trip.c file and add a function to browse all thetrip points like we do with the thermal zones, the govenors and thecooling devices.The same can be done for the cooling devices and the governor code butthat will come later as the current work in the thermal framework isto fix the trip point handling and use a generic trip point structure.No functional changes intended.Signed-off-by: Daniel Lezcano Reviewed-by: Zhang Rui Signed-off-by: Rafael J.

ffcb2fc86eb7ebc9f5524525fb57e1cccfbd1fc0 - thermal: k3_j72xx_bandgap: Add the bandgap driver support

Tue, 17 May 2022 19:29:20 +0200

thermal: k3_j72xx_bandgap: Add the bandgap driver supportAdd VTM thermal support. In the Voltage Thermal ManagementModule(VTM), K3 J72XX supplies a voltage reference and a temperaturesensor feature that are gathered in the band gap voltage andtemperature sensor (VBGAPTS) module. The band gap provides current andvoltage reference for its internal circuits and other analog IPblocks. The analog-to-digital converter (ADC) produces an output valuethat is proportional to the silicon temperature.Currently reading temperatures only is supported. There are noactive/passive cooling agent supported.J721e SoCs have errata i2128: https://www.ti.com/lit/pdf/sprz455The VTM Temperature Monitors (TEMPSENSORs) are trimmed during production,with the resulting values stored in software-readable registers. Softwareshould use these register values when translating the TemperatureMonitor output codes to temperature values.It has an involved workaround. Software needs to read the error codes for-40C, 30C, 125C from the efuse for each device & derive a new look up tablefor adc to temperature conversion. Involved calculating slopes & constantsusing 3 different straight line equations with adc refernce codes as they-axis & error codes in the x-axis.-40C to 30C30C to 125C125C to 150CWith the above 2 line equations we derive the full look-up table toworkaround the errata i2128 for j721e SoC.Tested temperature reading on J721e SoC & J7200 SoC.[daniel.lezcano@linaro.org: Generate look-up tables run-time]Signed-off-by: Daniel Lezcano Signed-off-by: Keerthy Link: https://lore.kernel.org/r/20220517172920.10857-3-j-keerthy@ti.comSigned-off-by: Daniel Lezcano List of files: /linux/drivers/thermal/Makefile
