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.
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.
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.
This provides an IOCTL interface to the IPMI message handler so userland processes may use IPMI. It supports poll() and select().
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.
This enables the IPMI watchdog timer.
This enables a function to power off the system with IPMI if the IPMI management controller is capable of this.
