The KCS (Keyboard Controller Style) interface is used to perform in-band IPMI communication between a server host and its BMC (BaseBoard Management Controllers). This driver exposes the KCS interface on ASpeed SOCs (AST2400 and AST2500) as a character device. Such SOCs are commonly used as BMCs and this driver implements the BMC side of the KCS interface.

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.

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,
|
|
by default, generate an IPMI event describing the panic to each
|
|
interface registered with the message handler. This is always
|
|
available, the module parameter for ipmi_msghandler named
|
|
panic_op can be set to "event" to chose this value, this config
|
|
simply causes the default value to be set to "event".

help
|
|
When a panic occurs, this will cause the IPMI message handler to,
|
|
by default, 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. This config
|
|
parameter sets the default value to generate these events,
|
|
the module parameter for ipmi_msghandler named panic_op can
|
|
be set to "string" to chose this value, this config simply
|
|
causes the default value to be set to "string".

Provides a driver for a SMBus interface to a BMC, meaning that you
