Kernel driver xgene-hwmon

Supported chips:

  • APM X-Gene SoC

Description

This driver adds hardware temperature and power reading support for APM X-Gene SoC using the mailbox communication interface. For device tree, it is the standard DT mailbox. For ACPI, it is the PCC mailbox.

The following sensors are supported

  • Temperature

    • SoC on-die temperature in milli-degree C

    • Alarm when high/over temperature occurs

  • Power

    • CPU power in uW

    • IO power in uW

sysfs-Interface

temp0_input

  • SoC on-die temperature (milli-degree C)

temp0_critical_alarm

  • An 1 would indicates on-die temperature exceeded threshold

power0_input

  • CPU power in (uW)

power1_input

  • IO power in (uW)
