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_DMI_DECODE
select IPMI_PLAT_DATA
bool
config IPMI_PLAT_DATA
bool
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_SSIF
tristate 'IPMI SMBus handler (SSIF)'
select 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_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.
endif # IPMI_HANDLER
config IPMI_KCS_BMC
tristate
config ASPEED_KCS_IPMI_BMC
depends on ARCH_ASPEED || COMPILE_TEST
select IPMI_KCS_BMC
select REGMAP_MMIO
tristate "Aspeed KCS IPMI BMC driver"
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.
config NPCM7XX_KCS_IPMI_BMC
depends on ARCH_NPCM7XX || COMPILE_TEST
select IPMI_KCS_BMC
select REGMAP_MMIO
tristate "NPCM7xx KCS IPMI BMC driver"
help
Provides a driver for the KCS (Keyboard Controller Style) IPMI
interface found on Nuvoton NPCM7xx 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.
config IPMI_KCS_BMC_CDEV_IPMI
depends on IPMI_KCS_BMC
tristate "IPMI character device interface for BMC KCS devices"
help
Provides a BMC-side character device implementing IPMI
semantics for KCS IPMI devices.
Say YES if you wish to expose KCS devices on the BMC for IPMI
purposes.
This support is also available as a module. The module will be
called kcs_bmc_cdev_ipmi.
config IPMI_KCS_BMC_SERIO
depends on IPMI_KCS_BMC && SERIO
tristate "SerIO adaptor for BMC KCS devices"
help
Adapts the BMC KCS device for the SerIO subsystem. This allows users
to take advantage of userspace interfaces provided by SerIO where
appropriate.
Say YES if you wish to expose KCS devices on the BMC via SerIO
interfaces.
This support is also available as a module. The module will be
called kcs_bmc_serio.
config IPMI_KCS_BMC_CDEV_RAW
depends on IPMI_KCS_BMC
tristate "Raw character device interface for BMC KCS devices"
help
Provides a BMC-side character device directly exposing the
data and status registers of a KCS device to userspace. While
KCS devices are commonly used to implement IPMI message
passing, they provide a general interface for exchange of
interrupts, data and status information between the BMC and
its host.
Say YES if you wish to use the KCS devices to implement
protocols that are not IPMI.
This support is also available as a module. The module will be
called kcs_bmc_cdev_raw.
config ASPEED_BT_IPMI_BMC
depends on ARCH_ASPEED || COMPILE_TEST
depends on REGMAP && REGMAP_MMIO && MFD_SYSCON
tristate "BT IPMI bmc driver"
help
Provides a driver for the BT (Block Transfer) IPMI interface
found on Aspeed SOCs (AST2400 and AST2500). The driver
implements the BMC side of the BT interface.
config IPMB_DEVICE_INTERFACE
tristate 'IPMB Interface handler'
depends on I2C
depends on I2C_SLAVE
help
Provides a driver for a device (Satellite MC) to
receive requests and send responses back to the BMC via
the IPMB interface. This module requires I2C support.
