A computer system includes a volatile memory and at least one processor. The volatile memory includes a protected storage segment (PSS) configured to store firmware-authentication program code for authenticating firmware of the computer system. The at least one processor is configured to receive a trigger to switch to a given version of the firmware, to obtain, in response to the trigger, a privilege to access the PSS, to authenticate the given version of the firmware by executing the firmware-authentication program code from the PSS, to switch to the given version of the firmware upon successfully authenticating the given version, and to take an alternative action upon failing to authenticate the given version.

Secure in-service firmware update

An apparatus includes a processor and split-read control circuitry (SRCC). The processor is to issue a set of one or more split-read requests for loading one or more data values to one or more respective local registers of the processor. The SRCC is to receive the set of one or more split-read requests, to read the one or more data values on behalf of the processor, and to write the data values into the one or more respective local registers. The processor and the SRCC are to coordinate a status of the split-read requests via a split-read-status indication.
