[PATCH 0/3] leds: trigger: Add led trigger for bpf

From: Daniel Hodges
Date: Fri Mar 22 2024 - 10:08:58 EST


This patch set adds a new led trigger that uses the bpf subsystem for
triggering leds. It is designed to be used in conjunction with a bpf
program(s) that can modify led state through the use of bpf kfuncs. This
is useful for providing a physical indication that a some event has
occurred. In the context of bpf this could range from handling a packet
to hitting a tracepoint.

leds: trigger: legtrig-bpf: Add ledtrig-bpf module
selftests/bpf: Add selftests for bpf led programs
leds: trigger: Add documentation for ledtrig-bpf
