| 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) |
