From f64da958dfc83335de1d2bef9d3868f30feb4e53 Mon Sep 17 00:00:00 2001 From: Corey Minyard Date: Tue, 8 May 2007 00:23:58 -0700 Subject: ipmi: add new IPMI nmi watchdog handling Convert over to the new NMI handling for getting IPMI watchdog timeouts via an NMI. This add config options to know if there is the ability to receive NMIs and if it has an NMI post processing call. Then it modifies the IPMI watchdog to take advantage of this so that it can know if an NMI comes in. It also adds testing that the IPMI NMI watchdog works.
