hwmon: Driver for disk and solid state drives with temperature sensors

2020-01-23T21:15:10+00:00

Reading the temperature of ATA drives has been supported for years by userspace tools such as smarttools or hddtemp. The downside of such tools is that they need to run with super-user privilege, that the temperatures are not reported by standard tools such as 'sensors' or 'libsensors', and that drive temperatures are not available for use in the kernel's thermal subsystem. This driver solves this problem by adding support for reading the temperature of ATA drives from the kernel using the hwmon API and by adding a temperature zone for each drive. With this driver, the hard disk temperature can be read using the unprivileged 'sensors' application: $ sensors drivetemp-scsi-1-0 drivetemp-scsi-1-0 Adapter: SCSI adapter temp1: +23.0°C or directly from sysfs: $ grep . /sys/class/hwmon/hwmon9/{name,temp1_input} /sys/class/hwmon/hwmon9/name:drivetemp /sys/class/hwmon/hwmon9/temp1_input:23000 If the drive supports SCT transport and reports temperature limits, those are reported as well. drivetemp-scsi-0-0 Adapter: SCSI adapter temp1: +27.0°C (low = +0.0°C, high = +60.0°C) (crit low = -41.0°C, crit = +85.0°C) (lowest = +23.0°C, highest = +34.0°C) The driver attempts to use SCT Command Transport to read the drive temperature. If the SCT Command Transport feature set is not available, or if it does not report the drive temperature, drive temperatures may be readable through SMART attributes. Since SMART attributes are not well defined, this method is only used as fallback mechanism. Cc: Chris Healy Cc: Linus Walleij Cc: Martin K.

hwmon: Add driver for Texas Instruments TMP512/513 sensor chips.

2019-11-22T05:26:40+00:00

TI's TMP512/513 are I2C/SMBus system monitor chips. These chips monitor the supply voltage, supply current, power consumption and provide one local and up to three (TMP513) remote temperature sensors.

hwmon: Add support for ltc2947

2019-11-06T22:37:19+00:00

The ltc2947 is a high precision power and energy monitor with an internal sense resistor supporting up to +/- 30A. Three internal no Latency ADCs ensure accurate measurement of voltage and current, while high-bandwidth analog multiplication of voltage and current provides accurate power measurement in a wide range of applications. Internal or external clocking options enable precise charge and energy measurements.

Pull MIPS updates from Paul Burton: "Main MIPS changes: - boot_mem_map is removed, providing a nice cleanup made possible by the recent removal of bootmem. - Some fixes to atomics, in general providing compiler barriers for smp_mb__{before,after}_atomic plus fixes specific to Loongson CPUs or MIPS32 systems using cmpxchg64(). - Conversion to the new generic VDSO infrastructure courtesy of Vincenzo Frascino. - Removal of undefined behavior in set_io_port_base(), fixing the behavior of some MIPS kernel configurations when built with recent clang versions. - Initial MIPS32 huge page support, functional on at least Ingenic SoCs. - pte_special() is now supported for some configurations, allowing among other things generic fast GUP to be used. - Miscellaneous fixes & cleanups. And platform specific changes: - Major improvements to Ingenic SoC support from Paul Cercueil, mostly enabled by the inclusion of the new TCU (timer-counter unit) drivers he's spent a very patient year or so working on. Plus some fixes for X1000 SoCs from Zhou Yanjie. - Netgear R6200 v1 systems are now supported by the bcm47xx platform. - DT updates for BMIPS, Lantiq & Microsemi Ocelot systems" * tag 'mips_5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: (89 commits) MIPS: Detect bad _PFN_SHIFT values MIPS: Disable pte_special() for MIPS32 with RiXi MIPS: ralink: deactivate PCI support for SOC_MT7621 mips: compat: vdso: Use legacy syscalls as fallback MIPS: Drop Loongson _CACHE_* definitions MIPS: tlbex: Remove cpu_has_local_ebase MIPS: tlbex: Simplify r3k check MIPS: Select R3k-style TLB in Kconfig MIPS: PCI: refactor ioc3 special handling mips: remove ioremap_cachable mips/atomic: Fix smp_mb__{before,after}_atomic() mips/atomic: Fix loongson_llsc_mb() wreckage mips/atomic: Fix cmpxchg64 barriers MIPS: Octeon: remove duplicated include from dma-octeon.c firmware: bcm47xx_nvram: Allow COMPILE_TEST firmware: bcm47xx_nvram: Correct size_t printf format MIPS: Treat Loongson Extensions as ASEs MIPS: Remove dev_err() usage after platform_get_irq() MIPS: dts: mscc: describe the PTP ready interrupt MIPS: dts: mscc: describe the PTP register range ...
