10 help
11 This enables the central IPMI message handler, required for IPMI
12 to work.
13
14 IPMI is a standard for managing sensors (temperature,
15 voltage, etc.) in a system.
16
17 See <file:Documentation/driver-api/ipmi.rst> for more details on the driver.

19 If unsure, say N.

30config IPMI_PANIC_EVENT
31 bool 'Generate a panic event to all BMCs on a panic'
32 help
33 When a panic occurs, this will cause the IPMI message handler to,
34 by default, generate an IPMI event describing the panic to each
35 interface registered with the message handler. This is always
36 available, the module parameter for ipmi_msghandler named
37 panic_op can be set to "event" to chose this value, this config
38 simply causes the default value to be set to "event".
39
40config IPMI_PANIC_STRING
41 bool 'Generate OEM events containing the panic string'
42 depends on IPMI_PANIC_EVENT
43 help
44 When a panic occurs, this will cause the IPMI message handler to,
45 by default, generate IPMI OEM type f0 events holding the IPMB
46 address of the panic generator (byte 4 of the event), a sequence
47 number for the string (byte 5 of the event) and part of the
48 string (the rest of the event). Bytes 1, 2, and 3 are the normal
49 usage for an OEM event. You can fetch these events and use the
50 sequence numbers to piece the string together. This config
51 parameter sets the default value to generate these events,
52 the module parameter for ipmi_msghandler named panic_op can
53 be set to "string" to chose this value, this config simply
54 causes the default value to be set to "string".

59 This provides an IOCTL interface to the IPMI message handler so
60 userland processes may use IPMI. It supports poll() and select().

66 Provides a driver for System Interfaces (KCS, SMIC, BT).
67 Currently, only KCS and SMIC are supported. If
68 you are using IPMI, you should probably say "y" here.

73 help
74 Provides a driver for a SMBus interface to a BMC, meaning that you
75 have a driver that must be accessed over an I2C bus instead of a
76 standard interface. This module requires I2C support.

81 help
82 Provides a driver for a system running right on the IPMB bus.
83 It supports normal system interface messages to a BMC on the IPMB
84 bus, and it also supports direct messaging on the bus using
85 IPMB direct messages. This module requires I2C support.
