Subject: [PATCH 8/8] ipmi: Change timeout and event poll to one second
Date: Mon, 03 May 2010 08:38:35 -0500 [thread overview]
Message-ID: <20100503133835.GH8130@minyard.local> (raw)
From: Corey Minyard <cminyard@mvista.com>
The timeouts in IPMI are in the 1-5 second range in message handling,
so a 1 second timeout is a reasonable thing to do. This should help
with reducing power consumption on idle systems.
