Annotated Snippet
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)Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
