摘要： A method and system that enables concurrent event handler execution in a system management interrupt (SMI) and processor management interrupt (PMI)-based dispatch-execution framework to service an SMI or PMI event. A plurality of event handlers are loaded into a hidden memory space that is accessible to a hidden execution mode supported by each of a plurality of processors in a multiprocessor computer system but is not accessible to other operating modes of those processors. The event handlers are then dispatched to two or more processors in response to the hidden execution mode event and concurrently executed to service the event. Various embodiments include use of a single event handler to service the event, multiple event handlers that perform different tasks, and multiple event handler instances that concurrently perform a single task. The invention also provides a resource locking mechanism to prevent resource access conflicts.

摘要： Embodiments of the invention provide systems and methods associated with a measurement engine in a server platform. In one such embodiment of the invention, the measurement engine hardware verifies/authenticates its own firmware and then system initialization firmware by measuring such firmware and storing measurement results in a register that is not spoofable by malicious code. In this instance, the measurement engine holds the host CPU complex in a reset state until the measurement engine has verified the system initialization firmware. In another such embodiment of the invention, the measurement engine hardware also measures firmware associated with one or more system service processors and stores such measurement results in a register. In this case, the measurement engine holds the system service processors and the host CPU complex in reset until the measurements are completed. Other embodiments are described.

摘要： A novel processor architecture and algorithms are provided which improve non-volatile memory updates and increases processor performance in successive generations of processors. A new processor architecture is supported by a software model consisting of two new firmware layers and the legacy 32 bit basic input output system (BIOS) firmware. The new firmware layers consist of a Processor Abstraction Layer (PAL) and a System Abstraction Layer (SAL). The PAL and SAL have procedure calls which allow updates of the firmware components in the non-volatile memory of a system, e.g. non-volatile ROM. The present invention includes invoking a system abstraction layer update procedure to implement a new input binary into the non-volatile memory. An algorithm for the non-volatile memory includes selecting a lead processor to perform an update and using the system abstraction layer update procedure. The system abstraction layer update procedure is used to call an appropriate authentication routine. The system abstraction layer update procedure is used to call a specific non-volatile memory implementation routine.
