Annotated Snippet
What: /sys/class/leds/<led>/delay_on
Date: Jun 2012
KernelVersion: 3.6
Contact: linux-leds@vger.kernel.org
Description:
Specifies for how many milliseconds the LED has to stay at
LED_FULL brightness after it has been armed.
Defaults to 100 ms.
What: /sys/class/leds/<led>/delay_off
Date: Jun 2012
KernelVersion: 3.6
Contact: linux-leds@vger.kernel.org
Description:
Specifies for how many milliseconds the LED has to stay at
LED_OFF brightness after it has been armed.
Defaults to 100 ms.
What: /sys/class/leds/<led>/invert
Date: Jun 2012
KernelVersion: 3.6
Contact: linux-leds@vger.kernel.org
Description:
Reverse the blink logic. If set to 0 (default) blink on for
delay_on ms, then blink off for delay_off ms, leaving the LED
normally off. If set to 1, blink off for delay_off ms, then
blink on for delay_on ms, leaving the LED normally on.
Setting this value also immediately changes the LED state.
What: /sys/class/leds/<led>/shot
Date: Jun 2012
KernelVersion: 3.6
Contact: linux-leds@vger.kernel.org
Description:
Write any non-empty string to signal an events, this starts a
blink sequence if not already running.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.
