hwmon: Driver for disk and solid state drives with temperature sensors 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 <cphealy@gmail.com> Cc: Linus Walleij <linus.walleij@linaro.org> Cc: Martin K.
