Management controller-based recovery of unresponsive bus interface controllers

Abstract

A computer platform contains a host and a management controller. The management controller operates independently of the host. A hardware processor of the management controller executes a firmware management stack to manage the host. A bus interface controller of the management controller generates bus signals for accessing non-volatile memory. A secure enclave of the management controller contains a bus interface controller recovery machine, which communicates with the bus interface controller in response to unresponsive behavior and reset the bus interface controller.
