    摘要: Systems, apparatuses, and methods, and for entering a secured system environment using multiple authenticated code modules are disclosed. In one embodiment, a processor includes a decoder and control logic. The decoder is to decode a secured enter instruction. The control logic is to find an entry corresponding to the processor in a match table in a master authenticated code module and to read a master header and an individual authenticated code module from the master authenticated code module in response to decoding the secured enter instruction.

    摘要: Technologies to generate an error record are described herein. A method includes performing a scan of one or more error logs to identify a source of data in response to an attempt to access the data, determining whether an amount of time to complete the scan will exceed a threshold value, and generating a notice that the error record will be deferred based on the determination. A system includes a data collector to scan one or more error logs to identify a source of data in response to an attempt to access the data, a controller to determine whether an amount of time to scan the error logs to identify the source of data will exceed a threshold value, and a signal generator to generate a signal indicating that the error record is to be deferred based on the determination.

    摘要: An apparatus and method for enumeration of processors during hot-plug of a compute node are described. The method includes the enumeration, in response to a hot-plug reset, of one or more processors. The enumeration is provided to a system architecture operating system in which a compute node is hot-plugged. Once enumeration is complete, the compute node is started in response to an operating system activation request. Accordingly, once device enumeration, as well as resource enumeration are complete, the one or more processors of the processor memory node are activated, such that the operating system may begin utilizing the processors of the hot-plugged compute node.

    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.
