It's useful to notify the user on + sporadic events, when there are no clear begin and end trap points, + or on dense events, where this blinks the LED at constant rate if + rearmed continuously. + + It also shows how to use the led_blink_set_oneshot() function. + + If unsure, say Y. + +config LEDS_TRIGGER_DISK + bool "LED Disk Trigger" + depends on ATA + help + This allows LEDs to be controlled by disk activity. + If unsure, say Y. + +config LEDS_TRIGGER_MTD + bool "LED MTD (NAND/NOR) Trigger" + depends on MTD + help + This allows LEDs to be controlled by MTD activity. + If unsure, say N. + +config LEDS_TRIGGER_HEARTBEAT + tristate "LED Heartbeat Trigger" + help + This allows LEDs to be controlled by a CPU load average. + The flash frequency is a hyperbolic function of the 1-minute + load average. + If unsure, say Y. + +config LEDS_TRIGGER_BACKLIGHT + tristate "LED backlight Trigger" + help + This allows LEDs to be controlled as a backlight device: they + turn off and on when the display is blanked and unblanked. + + If unsure, say N. + +config LEDS_TRIGGER_CPU + bool "LED CPU Trigger" + depends on !PREEMPT_RT + help + This allows LEDs to be controlled by active CPUs.
