From 30da885208b1392ebb76ebc6890e021dd61d4a4e Mon Sep 17 00:00:00 2001 From: Andrew Geissler Date: Mon, 1 Feb 2021 13:42:40 -0600 Subject: mpreboot: introduce new distro feature The memory preserving reboot is a feature utilized on IBM systems which allows a system to be rebooted with its memory preserved. This is utilized in situations where the host firmware has crashed and put the processor in an unusable state. The processors are put back in a good state by rebooting the system. Memory is preserved though so host firmware can capture the relevant data from memory needed to debug the cause of the failure. This feature is implemented across a few different repositories within OpenBMC so lets create a distro feature to enable it across all of the software stacks.
