IPMI: add 0.9 support

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

Add support for IPMI 0.9 systems to the IPMI driver.  Just handle a shorter
get device ID command with less information.

IPMI: fix hotmod remove lock

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

The removal of proc entries was done holding a lock, which is no longer
allowed.  There is no need for the lock, only a mutex is required, so switch
over to a mutex.

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.

IPMI: add polled interface

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

Currently the IPMI watchdog timer sets the watchdog timeout on a panic, but it
doesn't actually poll the interface to make sure the message goes out.

Add an interface for polling the IPMI driver, and add code to the IPMI
watchdog timer to poll the interface when the timer is set from a panic.

IPMI: remove bogus semaphore from watchdog

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

Lockdep was giving an error when loading the IPMI watchdog module.  It turns
out that if you try to claim a lock in a parameter handling routine, lockdep
won't see that lock as "static" yet because the module is not yet on the
module list, so it will complain.

However, the semaphore in question is completely unnecessary.  So just remove
it.

IPMI: don't init irq until ready

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

Patrick found a race at startup.  Interrupts were being enabled for the IPMI
interface before the driver was really ready to handle them.  This could
result in an oops if something was pending on the interface at startup and
interrupt were already enabled (technically shouldn't happen, but need to
cover for this in real life).  So move the IRQ setup to the code that starts
the actual IPMI processing.

Tweak /proc/ipmi removal

2007-10-17T15:42:51+00:00

Driver does
	proc_mkdir("ipmi", NULL);
but
	remove_proc_entry(proc_ipmi_root->name, &proc_root);

This is OK and working if only slightly inconsistent.  Also changing
proc_root to NULL will help OpenVZ which has multiple proc roots and, as we
now know, requires matching parents in such cases.
