Annotated Snippet
What: /sys/kernel/debug/dell-wmi-ddv-<wmi_device_name>/fan_sensor_information
Date: September 2022
KernelVersion: 6.1
Contact: Armin Wolf <W_Armin@gmx.de>
Description:
This file contains the contents of the fan sensor information
buffer, which contains fan sensor entries and a terminating
character (0xFF).
Each fan sensor entry contains:
- fan type (single byte)
- fan speed in RPM (two bytes, little endian)
See Documentation/wmi/devices/dell-wmi-ddv.rst for details.
What: /sys/kernel/debug/dell-wmi-ddv-<wmi_device_name>/thermal_sensor_information
Date: September 2022
KernelVersion: 6.1
Contact: Armin Wolf <W_Armin@gmx.de>
Description:
This file contains the contents of the thermal sensor information
buffer, which contains thermal sensor entries and a terminating
character (0xFF).
Each thermal sensor entry contains:
- thermal type (single byte)
- current temperature (single byte)
- min. temperature (single byte)
- max. temperature (single byte)
- unknown field (single byte)
See Documentation/wmi/devices/dell-wmi-ddv.rst for details.Annotation

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.
