Annotated Snippet
What: /sys/class/leds/<led>/multi_index
Date: March 2020
KernelVersion: 5.9
Contact: Dan Murphy <dmurphy@ti.com>
Description: read
The multi_index array, when read, will output the LED colors
as an array of strings as they are indexed in the
multi_intensity file.
For additional details please refer to
Documentation/leds/leds-class-multicolor.rst.
What: /sys/class/leds/<led>/multi_intensity
Date: March 2020
KernelVersion: 5.9
Contact: Dan Murphy <dmurphy@ti.com>
Description: read/write
This file contains an array of integers. The order of components
is described by the multi_index array. The maximum intensity value
supported by each color component is described by the multi_max_intensity
file. Writing intensity values larger than the maximum value of a
given color component will result in those values being clamped.
For additional details please refer to
Documentation/leds/leds-class-multicolor.rst.
What: /sys/class/leds/<led>/multi_max_intensity
Date: May 2026
KernelVersion: 7.2
Contact: Armin Wolf <W_Armin@gmx.de>
Description: read
This file contains an array of integers describing the maximum
intensity value for each intensity component.

- 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.
