    Abstract: The technology disclosed herein includes getting a system update configuration for managing updating of at least one of a software component and a firmware component of a computing system powered by a battery; determining an estimated system update time of usage of the battery to update the at least one of the software component and the firmware component based at least in part on the system update configuration; updating the at least one of the software component and the firmware component when resource requirements of the system update configuration are met and the estimated system update time is less than or equal to a minimum remaining time of usage of the battery; and deferring the updating when the resource requirements of the system update configuration are not met or the estimated system update time is greater than the minimum remaining time of usage of the battery.

    Abstract: Implementations of the disclosure provide processing device comprising: an interrupt managing circuit to receive an interrupt message directed to an application container from an assignable interface (AI) of an input/output (I/O) device. The interrupt message comprises an address space identifier (ASID), an interrupt handle and a flag to distinguish the interrupt message from a direct memory access (DMA) message. Responsive to receiving the interrupt message, a data structure associated with the interrupt managing circuit is identified. An interrupt entry from the data structure is selected based on the interrupt handle. It is determined that the ASID associated with the interrupt message matches an ASID in the interrupt entry. Thereupon, an interrupt in the interrupt entry is forwarded to the application container.

    Abstract: Examples include techniques for a trusted execution environment (TEE) at a compute server to request a service to be performed by an accelerator that is located at or with a service server. Examples are described of the TEE at the compute server authenticating the remote accelerator to enable establishment of one or more secure communication sessions for the accelerator to decrypt encrypted data, perform a transformation on the decrypted data and then re-encrypt the transformed data. Examples are also described of the TEE at the compute server authenticating a service TEE at the service server as well as the accelerator to enable the service TEE and the accelerator to collaboratively decrypt encrypted data, perform a transformation on the decrypted data and then re-encrypt the transformed data.

    Abstract: Techniques for scalable virtualization of an Input/Output (I/O) device are described. An electronic device composes a virtual device comprising one or more assignable interface (AI) instances of a plurality of AI instances of a hosting function exposed by the I/O device. The electronic device emulates device resources of the I/O device via the virtual device. The electronic device intercepts a request from the guest pertaining to the virtual device, and determines whether the request from the guest is a fast-path operation to be passed directly to one of the one or more AI instances of the I/O device or a slow-path operation that is to be at least partially serviced via software executed by the electronic device. For a slow-path operation, the electronic device services the request at least partially via the software executed by the electronic device.
