From 3d41a1399085cbd191ae7c47d706b3c6c6e44026 Mon Sep 17 00:00:00 2001 From: Patrick Rudolph Date: Mon, 22 Jul 2019 16:31:35 +0200 Subject: drivers/ipmi: Add option to wait for BMC The BMC on Supermicro X11SSH takes 34 seconds to start the IPMI KCS, but the default timeout of the IPMI KCS code is just 100 msec. Add a configurable timeout option to wait for the BMC to become ready. As it only should boot very long after power on reset, it's not a problem on reset or warm boot. Tested on Supermicro X11SSH. The IPMI driver doesn't fail with a time-out any more.
