It probes the device tree -for sensor devices during the __init phase and registers them with the 'hwmon'. -'hwmon' populates the 'sysfs' tree having attribute files, each for a given -sensor type and its attribute data. - -All the nodes in the DT appear under "/ibm,opal/sensors" and each valid node in -the DT maps to an attribute file in 'sysfs'. The node exports unique 'sensor-id' -which the driver uses to make an OPAL call to the firmware. - -Usage notes ------------ -The driver is built statically with the kernel by enabling the config -CONFIG_SENSORS_IBMPOWERNV. It can also be built as module 'ibmpowernv'. - -Sysfs attributes ----------------- - -fanX_input Measured RPM value. -fanX_min Threshold RPM for alert generation. -fanX_fault 0: No fail condition - 1: Failing fan - -tempX_input Measured ambient temperature. -tempX_max Threshold ambient temperature for alert generation. -tempX_highest Historical maximum temperature -tempX_lowest Historical minimum temperature -tempX_enable Enable/disable all temperature sensors belonging to the - sub-group.
