Corey Minyard 0dfe6e7ed4 ipmi: Turn off default probing of interfaces
The default probing can cause problems with some system, slow booting,
extra CPU usages, etc.  Turn it off by default and give a config option
to enable it.

menuconfig IPMI_HANDLER
tristate 'IPMI top-level message handler'
depends on HAS_IOMEM
help
This enables the central IPMI message handler, required for IPMI
to work.
IPMI is a standard for managing sensors (temperature,
voltage, etc.) in a system.
See <file:Documentation/IPMI.txt> for more details on the driver.
If unsure, say N.
if IPMI_HANDLER
config IPMI_PANIC_EVENT
bool 'Generate a panic event to all BMCs on a panic'
help
When a panic occurs, this will cause the IPMI message handler to
generate an IPMI event describing the panic to each interface
registered with the message handler.
config IPMI_PANIC_STRING
bool 'Generate OEM events containing the panic string'
depends on IPMI_PANIC_EVENT
help
When a panic occurs, this will cause the IPMI message handler to
generate IPMI OEM type f0 events holding the IPMB address of the
panic generator (byte 4 of the event), a sequence number for the
string (byte 5 of the event) and part of the string (the rest of the
event). Bytes 1, 2, and 3 are the normal usage for an OEM event.
You can fetch these events and use the sequence numbers to piece the
string together.
config IPMI_DEVICE_INTERFACE
tristate 'Device interface for IPMI'
help
This provides an IOCTL interface to the IPMI message handler so
userland processes may use IPMI. It supports poll() and select().
config IPMI_SI
tristate 'IPMI System Interface handler'
help
Provides a driver for System Interfaces (KCS, SMIC, BT).
Currently, only KCS and SMIC are supported. If
you are using IPMI, you should probably say "y" here.
config IPMI_SI_PROBE_DEFAULTS
bool 'Probe for all possible IPMI system interfaces by default'
default n
depends on IPMI_SI
help
Modern systems will usually expose IPMI interfaces via a discoverable
firmware mechanism such as ACPI or DMI. Older systems do not, and so
the driver is forced to probe hardware manually. This may cause boot
delays. Say "n" here to disable this manual probing. IPMI will then
only be available on older systems if the "ipmi_si_intf.trydefaults=1"
boot argument is passed.
config IPMI_WATCHDOG
tristate 'IPMI Watchdog Timer'
help
This enables the IPMI watchdog timer.
config IPMI_POWEROFF
tristate 'IPMI Poweroff'
help
This enables a function to power off the system with IPMI if
the IPMI management controller is capable of this.
