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.

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".

56config IPMI_DEVICE_INTERFACE
57	tristate 'Device interface for IPMI'
58	help
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.

70config IPMI_SSIF
71	tristate 'IPMI SMBus handler (SSIF)'
72	depends on I2C
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.
77
78config IPMI_IPMB
79	tristate 'IPMI IPMB interface'
80	depends on I2C && I2C_SLAVE
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.
