leds: trigger: panic: Simplify led_trigger_set_panic

2024-03-07T08:48:01+00:00

I don't see why we iterate over all triggers to find the panic trigger. We *are* the panic trigger. Therefore we also know that the panic trigger doesn't have an activate() hook. So we can simplify the code significantly.

leds: trigger: panic: Don't register panic notifier if creating the trigger failed

2023-12-21T14:54:45+00:00

It doesn't make sense to register the panic notifier if creating the panic trigger failed. Signed-off-by: Heiner Kallweit Link: https://lore.kernel.org/r/8a61e229-5388-46c7-919a-4d18cc7362b2@gmail.com Signed-off-by: Lee Jones

kernel.h: split out panic and oops helpers

2021-07-01T18:06:04+00:00

kernel.h is being used as a dump for all kinds of stuff for a long time. Here is the attempt to start cleaning it up by splitting out panic and oops helpers. There are several purposes of doing this: - dropping dependency in bug.h - dropping a loop by moving out panic_notifier.h - unload kernel.h from something which has its own domain At the same time convert users tree-wide to use new headers, although for the time being include new header back to kernel.h to avoid twisted indirected includes for existing users.

leds: triggers: Allow to switch the trigger to "panic" on a kernel panic

2016-05-06T08:22:09+00:00

This commit adds a new led_cdev flag LED_PANIC_INDICATOR, which allows to mark a specific LED to be switched to the "panic" trigger, on a kernel panic. This is useful to allow the user to assign a regular trigger to a given LED, and still blink that LED on a kernel panic.

leds: trigger: Introduce a kernel panic LED trigger

2016-03-30T09:16:39+00:00

This commit introduces a new LED trigger which allows to configure a LED to blink on a kernel panic (through panic_blink). Notice that currently the Openmoko FreeRunner (GTA02) mach code sets panic_blink to blink a hard-coded LED. The new trigger is meant to introduce a generic mechanism to achieve this.
