Abstract: Examples disclosed herein relate to selecting and loading firmware volumes. A computing device is booted to a state where the computing device is capable of accessing a memory available to multiple other computing devices. The memory includes multiple firmware volumes. In one example, at least one firmware volume is selected based on a hardware configuration or hardware components of the computing device. The selected firmware volumes are loaded.

Abstract: Systems and methods are provided for a modular switch system that comprises disaggregated components, plugins, and managers that enable flexibility to adjust the dynamic configuration of a switch system. This can create modularity and customizability at different times of the lifecycle of the currently configured switch system.

Abstract: Examples relate to firmware-based provisioning of hardware resources. In some of the examples, firmware discovers and takes ownership of a hardware resource. At this stage, the firmware performs a test to verify the hardware resource. The firmware then assigns the hardware resource to an OS instance. At this stage, the firmware can suspend assigning further hardware resources to the OS instance in response to a satisfied notification from the OS instance.

Abstract: One embodiment can provide a node controller in a multiprocessor system. The node controller can include a processor interface to interface with a processor, a memory interface to interface with a fabric-attached memory, a node-controller interface to interface with a remote node controller, and a cache-coherence logic to operate in a first mode or a second mode. The cache-coherence logic manages cache coherence for a local memory of the processor coupled to the processor interface when operating in the first mode, and the cache-coherence logic manages cache coherence for the fabric-attached memory coupled to the memory interface when operating in the second mode.

Abstract: A dynamic firmware update process includes finding an updated version of a dynamic data-object in firmware memory. A callback handle for an in-use version of the dynamic data object in use by a consumer is identified. The consumer of updated version of dynamic data object is notified using the callback handle.
