main: Add --sink-actions=... command-line option Allow explicit configuration of the actions to take when a valid command is received from the source. This patch gives the current set of actions the name 'sysrq'. Signed-off-by: Andrew Jeffery <andrew@aj.id.au> Change-Id: Ie8e7446599edb5927468865bcea36b596aef12f6
debug-trigger listens for an external signal that the BMC is in some way unresponsive. When the signal is received it triggers a crash to collect debug data and reboots the system in the hope that it will recover.
debug-trigger implements a simple protocol over an LPC KCS device as its trigger source.
debug-trigger implements a single action once the trigger event is received, which is to crash the kernel via /proc/sysrq-trigger. For systems with kdump configured this results in collection of system state as context for why the system was externally unresponsive.
