Remote Management Module IPMI Support

The Intel

RMM IPMI functionality is that of an IPMI satellite controller to the baseboard BMC.

As a satellite controller, the Intel

sued ove PMB

he Intel RMM IPMI stack complements the IPMI stack running on the baseboard BMC. The

RMM contains two main components. The components are as follows:

 Set of IPMI APIs

 IPMI daemon

11.1 IPMI APIs

The IPMI APIs provide interfaces between applications running on the Intel

RMM and the IPMI

daemon. It is via these IPMI APIs that applications can perform various IPMI operations. The

IPMI APIs encapsulate IPMI commands providing the applications a clear, easy-to-use interface

to execute IPMI commands on the BMC.

11.2 IPMI Daemon

The IPMI daemon is the main body of the IPMI stack of the Intel

RMM. The IPMI daemon

works with the BMC which implements a full IPMI 2.0 compliant firmware stack. All IPMI

commands are executed on the BMC.

The IPMI daemon on the Intel

RMM supports following two IPMI channels:

 Virtual KCS (V-KCS) channel

 IPMB channel

11.2.1 V-KCS Channel

The V-KCS channel is used by the IPMI APIs to communicate with the IPMI daemon. The

V-KCS channel is essentially a BSD-style socket that supports up to four concurrent

connections between the IPMI APIs and the IPMI daemon. The V-KCS channel itself is

implemented in the IPMI APIs and transparent to the applications.

RMM can respond to IPMI commands is r the I

us by the BMC.
