Abstract: Systems and methods to support system management mode (SMM) update and telemetry in runtime for bare metal deployments. During runtime operation of a host operating system on a bare metal platform having a management controller and including a processing unit on which the host operating system (OS) and host BIOS are executed, an out-of-band runtime update is performed to update secure execution mode (e.g., SMM) runtime firmware for the bare metal platform using an out-of-band channel comprising an interrupt driven, shared memory-based data exchange channel between the management controller and the host BIOS. This enables secure execution mode runtime firmware to be updated without during runtime without having to reboot the platform or restart the OS kernel. The out-of-band channel also supports exchange of telemetry data logged by the host BIOS during the runtime update with the management controller.

Abstract: Methods, apparatus, and systems for upgradable microcode (uCode) loading and activation in runtime for bare metal deployments that support runtime update of the uCode loading procedure as well as dynamic load of activation procedure(s) specific to uCode patch and activation policy specific to users. The solution provides several advantages, including enabling cloud service providers to hot-patch the uCode through a standalone uCode loader runtime service in BIOS firmware for bare metal deployment without tenant system involvement. The support of runtime update of uCode loading procedures decouples uCode loading logic from uCode loader framework. This removes dependencies on the uCode loader runtime service when needing to update the uCode loading logic.

Abstract: System, method, and instructions for providing system management mode (SMM) runtime telemetry support. An SMM Telemetry Service component is responsible for collecting telemetry information from other SMM components, as well as exposing the information to non-firmware component on request. The SMM Telemetry Service collects telemetry information produced by an SMM Runtime Update handler and other SMM drivers and exposes the telemetry information at runtime to an upper layer OS consumer or management unit (e.g., BMC, CSME, etc.). Since the SMM Telemetry Service is a standalone module and independent of other SMM service(s), the service is available even during a runtime SMM Driver Update. The embodiments also disclose a mechanism for managing a shared telemetry data region that can be accessed by the data producer (SMM components) and consumer (non-SMM components), without introducing additional SMI that affects system performance.
