ed42cfa8 | 1 | Kernel driver xgene-hwmon |
2 | ======================== | |
3 | ||
4 | Supported chips: | |
5 | * APM X-Gene SoC | |
6 | ||
7 | Description | |
8 | ----------- | |
9 | ||
10 | This driver adds hardware temperature and power reading support for | |
11 | APM X-Gene SoC using the mailbox communication interface. | |
12 | For device tree, it is the standard DT mailbox. | |
13 | For ACPI, it is the PCC mailbox. | |
14 | ||
15 | The following sensors are supported | |
16 | ||
17 | * Temperature | |
18 | - SoC on-die temperature in milli-degree C | |
19 | - Alarm when high/over temperature occurs | |
20 | * Power | |
21 | - CPU power in uW | |
22 | - IO power in uW | |
23 | ||
24 | sysfs-Interface | |
25 | --------------- | |
26 | ||
27 | temp0_input - SoC on-die temperature (milli-degree C) | |
28 | temp0_critical_alarm - An 1 would indicates on-die temperature exceeded threshold | |
29 | power0_input - CPU power in (uW) | |
30 | power1_input - IO power in (uW) |
