Abstract: Disclosed herein are systems and methods for isolating input/output computing resources. In some embodiments, a host device may include a processor and logic coupled with the processor, to identify a tag identifier (Tag ID) for a process or container of the host device. The Tag ID may identify a queue pair of a hardware device of the host device for an outbound transaction from the processor to the hardware device, to be conducted by the process or container. Logic may further map the Tag ID to a Process Address Space Identifier (PASID) associated with an inbound transaction from the hardware device to the processor that used the identified queue pair. The process or container may use the PASID to conduct the outbound transaction via the identified queue pair. Other embodiments may be disclosed and/or claimed.

Abstract: An example electronic apparatus is for accelerating a para-virtualization network interface. The electronic apparatus includes a descriptor hub performing bi-directionally communication with a guest memory accessible by a guest and with a host memory accessible by a host. The guest includes a plurality of virtual machines. The host includes a plurality of virtual function devices. The virtual machines are communicatively coupled to the electronic apparatus through a central processing unit. The communication is based upon para-virtualization packet descriptors and network interface controller virtual function-specific descriptors. The electronic apparatus also includes a device association table communicatively coupled to the descriptor hub and to store associations between the virtual machines and the virtual function devices. The electronic apparatus further includes an input-output memory map unit (IOMMU) to perform direct memory access (DMA) remapping and interrupt remapping.

Abstract: There is disclosed in one example a computing apparatus, including: a hardware platform configured to communicatively couple with a multi-tenant cloud service, the multi-tenant cloud service including an oversubscribable resource; and a service assurance for oversubscribable resource (SAOR) engine configured to: receive tenant subscriptions to the oversubscribable resource, wherein tenant subscriptions exceed available instances of the oversubscribable resource; receive per-tenant quality of service (QoS) metrics for the oversubscribable resource; receive an allocation request from a guest for allocation of an instance of the oversubscribable resource; compare the request to currently-available instances of the oversubscribable resource; determine that the oversubscribable resource has capacity to service the request according to the QoS metrics of the tenant; and allocate an instance of the oversubscribable resource to the guest.

Abstract: Examples described herein relate to a reliable transport protocol for packet transmission using an Address Family of an eXpress Data Path (AF_XDP) queue framework, wherein the AF_XDP queue framework is to provide a queue for received packet receipt acknowledgements (ACKs). In some examples, an AF_XDP socket is to connect a service with a driver for the network device, one or more queues are associated with the AF_XDP socket, and at least one of the one or more queues comprises a waiting queue for received packet receipt ACKs. In some examples, at least one of the one or more queues is to identify one or more packets for which ACKs have been received. In some examples, the network device is to re-transmit a packet identified by a descriptor in the waiting queue based on non-receipt of an ACK associated with the packet from a receiver.
