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 and apparatus for seamless system management mode (SMM) code injection. A code injection listener is installed in BIOS during booting of the computer system or platform. During operating system (OS) runtime operation a secure execution mode code injection image comprising injected code is received and delivered to the BIOS. The processor execution mode is switched to a secure execution mode such as SMM, and while in the secure execution mode the injected code is accessed and executed on the processor to effect one or more changes such as patching processor microcode, a profile or policy reconfiguration, and a security fix. The solution enables platform changes to be effected during OS runtime without having to reboot the system.

Abstract: Examples described herein relate to execution of multiple Reliability Availability Serviceability (RAS) processes on different processors of the at least two processors to provide fallback from a first RAS process to a second RAS process executing on a processor of the at least two processors based on failure or timeout of the first RAS process. In some examples, the different processors comprise independently operating processors whereby failure or inoperability of one of the different processors is independent of another of the different processors. In some examples, failure or timeout of the first RAS process comprises failure of the second RAS process to receive an operating status signal from the first RAS process.

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.
