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.

if IPMI_HANDLER

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.

config IPMI_SI_ASYNC_INIT
	bool 'Asynchronous initialization of IPMI System Interface'
	depends on IPMI_SI
	default n
	help
	  Offloads individual SMI inits. It speeds up the boot time.
	  It also introduces a very small risk that something else might fail
	  if it depends on synchronous IPMI init.

config IPMI_SSIF
	tristate 'IPMI SMBus handler (SSIF)'
	depends on I2C
	help
	  Provides a driver for a SMBus interface to a BMC, meaning that you
	  have a driver that must be accessed over an I2C bus instead of a
	  standard interface.  This module requires I2C support.

config IPMI_IPMB
	tristate 'IPMI IPMB interface'
	depends on I2C && I2C_SLAVE
	help
	  Provides a driver for a system running right on the IPMB bus.
	  It supports normal system interface messages to a BMC on the IPMB
	  bus, and it also supports direct messaging on the bus using
	  IPMB direct messages.  This module requires I2C support.

config IPMI_LS2K
	bool 'Loongson-2K IPMI interface'
	depends on LOONGARCH
	select MFD_LS2K_BMC_CORE
	help
	  Provides a driver for Loongson-2K IPMI interfaces.

config IPMI_POWERNV
	depends on PPC_POWERNV
	tristate 'POWERNV (OPAL firmware) IPMI interface'
	help
	  Provides a driver for OPAL firmware-based IPMI interfaces.

config IPMI_WATCHDOG
	tristate 'IPMI Watchdog Timer'
	help
	  This enables the IPMI watchdog timer.

config IPMI_POWEROFF
	tristate 'IPMI Poweroff'
	help
	  This enables a function to power off the system with IPMI if
	  the IPMI management controller is capable of this.

	help
	  Provides a driver for the KCS (Keyboard Controller Style) IPMI
	  interface found on Aspeed SOCs (AST2400 and AST2500).

	  The driver implements the BMC side of the KCS contorller, it
	  provides the access of KCS IO space for BMC side.

	  Provides a driver for the KCS (Keyboard Controller Style) IPMI
	  interface found on Nuvoton NPCM SOCs.

	  The driver implements the BMC side of the KCS contorller, it
	  provides the access of KCS IO space for BMC side.

	  This support is also available as a module.  If so, the module
	  will be called kcs_bmc_npcm7xx.

	  called kcs_bmc_cdev_ipmi.

config IPMI_KCS_BMC_SERIO

	  to take advantage of userspace interfaces provided by SerIO where
	  appropriate.

	  interfaces.

	  This support is also available as a module. The module will be
