0010 help
0011 This enables the central IPMI message handler, required for IPMI
0012 to work.
0013
0014 IPMI is a standard for managing sensors (temperature,
0015 voltage, etc.) in a system.
0016
0017 See <file:Documentation/driver-api/ipmi.rst> for more details on the driver.

0031 bool 'Generate a panic event to all BMCs on a panic'
0032 help
0033 When a panic occurs, this will cause the IPMI message handler to,
0034 by default, generate an IPMI event describing the panic to each
0035 interface registered with the message handler. This is always
0036 available, the module parameter for ipmi_msghandler named
0037 panic_op can be set to "event" to chose this value, this config
0038 simply causes the default value to be set to "event".

0040 config IPMI_PANIC_STRING
0041 bool 'Generate OEM events containing the panic string'
0042 depends on IPMI_PANIC_EVENT
0043 help
0044 When a panic occurs, this will cause the IPMI message handler to,
0045 by default, generate IPMI OEM type f0 events holding the IPMB
0046 address of the panic generator (byte 4 of the event), a sequence
0047 number for the string (byte 5 of the event) and part of the
0048 string (the rest of the event). Bytes 1, 2, and 3 are the normal
0049 usage for an OEM event. You can fetch these events and use the
0050 sequence numbers to piece the string together. This config
0051 parameter sets the default value to generate these events,
0052 the module parameter for ipmi_msghandler named panic_op can
0053 be set to "string" to chose this value, this config simply
0054 causes the default value to be set to "string".

0074 Provides a driver for a SMBus interface to a BMC, meaning that you
0075 have a driver that must be accessed over an I2C bus instead of a
0076 standard interface. This module requires I2C support.

0083 It supports normal system interface messages to a BMC on the IPMB
0084 bus, and it also supports direct messaging on the bus using
0085 IPMB direct messages. This module requires I2C support.
