hwmon: (drivetemp) Use drivetemp's true module name in Kconfig section

2020-04-12T22:12:51Z

The addition of the support for reading the temperature of ATA drives as per commit 5b46903d8bf3 ("hwmon: Driver for disk and solid state drives with temperature sensors") lists in the respective Kconfig section the name of the module to be optionally built as "satatemp". However, building the kernel modules with "CONFIG_SENSORS_DRIVETEMP=m", does not generate a file named "satatemp.ko". Instead, the rest of the original commit uses the term "drivetemp" and a file named "drivetemp.ko" ends up in the kernel's modules directory. This file has the right ingredients: $ strings /path/to/drivetemp.ko | grep ^description description=Hard drive temperature monitor and modprobing it produces the expected result: # drivetemp is not loaded $ sensors -u drivetemp-scsi-4-0 Specified sensor(s) not found! $ sudo modprobe drivetemp $ sensors -u drivetemp-scsi-4-0 drivetemp-scsi-4-0 Adapter: SCSI adapter temp1: temp1_input: 35.000 temp1_max: 60.000 temp1_min: 0.000 temp1_crit: 70.000 temp1_lcrit: -40.000 temp1_lowest: 20.000 temp1_highest: 36.000 Fix Kconfig by referring to the true name of the module.

hwmon: Support ADI Fan Control IP

2020-03-09T03:35:46Z

The purpose of this IP Core is to control the fan used for the cooling of a Xilinx Zynq Ultrascale+ MPSoC without the need of any external temperature sensors. To achieve this, the IP core uses the PL SYSMONE4 primitive to obtain the PL temperature and, based on those readings, it then outputs a PWM signal to control the fan rotation accordingly.

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

2020-01-23T21:15:10Z

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.
