What: /sys/devices/LNXSYSTM:00/LNXSYBUS:00/TOS{1900,620{0,7,8}}:00/kbd_backlight_mode
Date: June 8, 2014
KernelVersion: 3.15
Contact: Azael Avalos <coproscefalo@gmail.com>
Description: This file controls the keyboard backlight operation mode, valid
values are:
* 0x1 -> FN-Z
* 0x2 -> AUTO (also called TIMER)
* 0x8 -> ON
* 0x10 -> OFF
Note that from kernel 3.16 onwards this file accepts all listed
parameters, kernel 3.15 only accepts the first two (FN-Z and
AUTO).
Also note that toggling this value on type 1 devices, requires
a reboot for changes to take effect.

Date: June 8, 2014
KernelVersion: 3.15
Contact: Azael Avalos <coproscefalo@gmail.com>
Description: This file controls the timeout of the keyboard backlight
whenever the operation mode is set to AUTO (or TIMER),
valid values range from 0-60.
Note that the kernel 3.15 only had support for the first
keyboard type, the kernel 3.16 added support for the second
type and the range accepted for type 2 is 1-60.

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.
