VIRTUAL BASEBOARD MANAGEMENT CONTROLLER

摘要

A system firmware agent providing the capabilities of a Baseboard Management Controller (BMC) from within System Management Mode (SMM) is discussed. A virtual BMC provides dedicated communication channels for system firmware, other BMCs in the platform and remote management agents. The virtual BMC may monitor the status of the system, record system events, and control the system state.

主权项

1. A computing device-implemented method for improved platform management, comprising:
generating a System Management Interrupt (SMI), the SMI invoking a transition to System Management Mode (SMM) by a central processing unit (CPU) in the computing device; receiving a management command with a firmware-based virtual Baseboard Management Controller (vBMC) executing during SMM; performing a management function for the computing device with the vBMC based on the management command; and communicating management data resulting from the performance of the management function while the vBMC is executing during SMM.
