Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

menuconfig IPMI_HANDLER
	tristate 'IPMI top-level message handler'
	depends on HAS_IOMEM
	select IPMI_DMI_DECODE if DMI
	help
	  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/driver-api/ipmi.rst> 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".

config IPMI_PANIC_STRING
	bool 'Generate OEM events containing the panic string'
	depends on IPMI_PANIC_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".

config IPMI_DEVICE_INTERFACE
	tristate 'Device interface for IPMI'
	help
	  This provides an IOCTL interface to the IPMI message handler so
	  userland processes may use IPMI.  It supports poll() and select().

config IPMI_SI
	tristate 'IPMI System Interface handler'
	select IPMI_PLAT_DATA
	help
	  Provides a driver for System Interfaces (KCS, SMIC, BT).
	  Currently, only KCS and SMIC are supported.  If
	  you are using IPMI, you should probably say "y" here.
