    Abstract: An apparatus and method are described for staging and activating microcode of a processor. For example, one embodiment of a processor comprises: a plurality of functional blocks, each functional block operable, at least in part, based on microcode and including a non-volatile memory to store a corresponding microcode update (MCU); a plurality of MCU staging memories, each MCU staging memory to temporarily store one or more of the MCUs for one or more corresponding functional blocks of the plurality of functional blocks; authentication hardware logic to attempt to validate each MCU of the one or more MCUs stored in each MCU staging memory, wherein each MCU is to be copied to a non-volatile memory of a corresponding functional block only after a successful authentication.

    Abstract: Methods and apparatus for scalable MCTP infrastructure. A system is split into independent MCTP domains, wherein each MCTP domain uses Endpoint Identifiers (EIDs) for endpoint devices within the MCTP domain in a manner similar to conventional MCTP operations. A new class of MCTP devices (referred to as a Domain Controllers) is provided to enable inter-domain communication and communication with global devices. Global traffic originators or receivers like a BMC (Baseboard Management Controller), Infrastructure Processing Unit (IPU), Smart NIC (Network Interface Card), Debugger, or PROT (Platform Root or Trust) discover and establish two-way communication through the Domain Controllers to any of the devices in the target domain(s). The Domain Controllers are configured to implement tunneled connections between global devices and domain endpoint devices. The tunneled connections may employ encapsulated messages with outer and inner headers and/or augmented MCTP messages with repurposed fields used to store source and destination EIDs.

    Abstract: Methods and apparatus for lifetime telemetry on memory error statistics to improve memory failure analysis and prevention. Memory error information corresponding to detected correctable errors and uncorrectable memory errors are monitored, with the memory error information identifying an associated DRAM device in an associated DIMM. Corresponding micro-level error bits information from the memory error information is decoded and Micro-level Error Statistic Indicators (MESIs) are generated. Information associated with the MESIs from DRAM devices on the DIMMs are periodically written to persistent storage on those DIMMs. The MESIs for a given DIMM are updated over the lifetime of the DIMM.
