menuconfig IPMI_HANDLER
tristate 'IPMI top-level message handler'
depends on HAS_IOMEM
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/IPMI.txt> 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
generate an IPMI event describing the panic to each interface
registered with the message handler.
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
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.
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'
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.

ipmi: add an Aspeed BT IPMI BMC driver This patch adds a simple device driver to expose the iBT interface on Aspeed SOCs (AST2400 and AST2500) as a character device. Such SOCs are commonly used as BMCs (BaseBoard Management Controllers) and this driver implements the BMC side of the BT interface. The BT (Block Transfer) interface is used to perform in-band IPMI communication between a host and its BMC. Entire messages are buffered before sending a notification to the other end, host or BMC, that there is data to be read. Usually, the host emits requests and the BMC responses but the specification provides a mean for the BMC to send SMS Attention (BMC-to-Host attention or System Management Software attention) messages. For this purpose, the driver introduces a specific ioctl on the device: 'BT_BMC_IOCTL_SMS_ATN' that can be used by the system running on the BMC to signal the host of such an event. The device name defaults to '/dev/ipmi-bt-host' Signed-off-by: Alistair Popple <alistair@popple.id.au> Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Joel Stanley <joel@jms.id.au> [clg: - checkpatch fixes - added a devicetree binding documentation - replace 'bt_host' by 'bt_bmc' to reflect that the driver is the BMC side of the IPMI BT interface - renamed the device to 'ipmi-bt-host' - introduced a temporary buffer to copy_{to,from}_user - used platform_get_irq() - moved the driver under drivers/char/ipmi/ but kept it as a misc device - changed the compatible cell to "aspeed,ast2400-bt-bmc" ] Signed-off-by: Cédric Le Goater <clg@kaod.org> Acked-by: Arnd Bergmann <arnd@arndb.de> [clg: - checkpatch --strict fixes - removed the use of devm_iounmap, devm_kfree in cleanup paths - introduced an atomic-t to limit opens to 1 - introduced a mutex to protect write/read operations] Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Cédric Le Goater <clg@kaod.org> Signed-off-by: Corey Minyard <cminyard@mvista.com>

config ASPEED_BT_IPMI_BMC
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.
