ipmi: Fix IPMI errors due to timing problems

2011-03-10T21:21:16+00:00

This patch fixes an issue in OpenIPMI module where sometimes an ABORT command
is sent after sending an IPMI request to BMC causing the IPMI request to fail.

char/ipmi: fix OOPS caused by pnp_unregister_driver on unregistered driver

2011-02-11T02:00:21+00:00

This patch fixes an OOPS triggered when calling modprobe ipmi_si a
second time after the first modprobe returned without finding any ipmi
devices.  This can happen if you reload the module after having the
first module load fail.  The driver was not deregistering from PNP in
that case.

Peter Huewe originally reported this patch and supplied a fix, I have a
different patch based on Linus' suggestion that cleans things up a bit
more.

x86: Convert some devices to use DIE_NMIUNKNOWN

2011-01-07T14:08:52+00:00

They are a handful of places in the code that register a die_notifier
as a catch all in case no claims the NMI.  Unfortunately, they trigger
on events like DIE_NMI and DIE_NMI_IPI, which depending on when they
registered may collide with other handlers that have the ability to
determine if the NMI is theirs or not.

The function unknown_nmi_error() makes one last effort to walk the
die_chain when no one else has claimed the NMI before spitting out
messages that the NMI is unknown.

This is a better spot for these devices to execute any code without
colliding with the other handlers.

The two drivers modified are only compiled on x86 arches I believe, so
they shouldn't be affected by other arches that may not have
DIE_NMIUNKNOWN defined.

IPMI: Add one interface to get more info of low-level IPMI device

2010-12-14T05:21:51+00:00

The IPMI smi_watcher will be used to catch the IPMI interface as they
come or go.  In order to communicate with the correct IPMI device, it
should be confirmed whether it is what we wanted especially on the
system with multiple IPMI devices. But the new_smi callback function
of smi_watcher provides very limited info(only the interface number
and dev pointer) and there is no detailed info about the low level
interface. For example: which mechansim registers the IPMI
interface(ACPI, PCI, DMI and so on).

This is to add one interface that can get more info of low-level IPMI
device. For example: the ACPI device handle will be returned for the
pnp_acpi IPMI device.
