ipmi watchdog : add panic_wdt_timeout parameter

2015-11-16T12:28:43+00:00

In order to allow panic actions to be processed, the ipmi watchdog
driver sets a new timeout value on panic. The 255s timeout
was designed to allow kdump and others actions on panic, as in
http://lkml.iu.edu/hypermail/linux/kernel/0711.3/0258.html

This is counter-intuitive for a end-user who sets watchdog timeout
value to something like 30s and who expects BMC to reset the system
within 30s of a panic.

This commit allows user to configure the timeout on panic.

ipmi:ssif: Ignore spaces when comparing I2C adapter names

2015-05-05T19:24:45+00:00

Some of the adapters have spaces in their names, but that's really
hard to pass in as a module or kernel parameters.  So ignore the
spaces.

IPMI: Remove SMBus driver info from the docs

2012-10-17T01:07:12+00:00

Some documentation for the SMBus driver is in the IPMI docs, but that
code is not in the kernel tree at this point.  So remove the docs to
avoid confusion.

ipmi: add parameter to limit CPU usage in kipmid

2010-03-12T23:52:39+00:00

In some cases kipmid can use a lot of CPU.  This adds a way to tune the
CPU used by kipmid to help in those cases.  By setting kipmid_max_busy_us
to a value between 100 and 500, it is possible to bring down kipmid CPU
load to practically 0 without loosing too much ipmi throughput
performance.  Not setting the value, or setting the value to zero,
operation is unaffected.

IPMI: new NMI handling

2007-10-18T21:37:32+00:00

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.
