14         IPMI is a standard for managing sensors (temperature,
15         voltage, etc.) in a system.

17         See <file:Documentation/IPMI.txt> for more details on the driver.

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".

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

67	 Currently, only KCS and SMIC are supported.  If
68	 you are using IPMI, you should probably say "y" here.

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.
