Abstract: Techniques for quality of service (QoS) support for input/output devices and other agents are described. In embodiments, a processing device includes execution circuitry to execute a plurality of software threads; hardware to control monitoring or allocating, among the plurality of software threads, one or more shared resources; and configuration storage to enable the monitoring or allocating of the one or more shared resources among the plurality of software threads and one or more channels through which one or more devices are to be connected to the one or more shared resources.

Abstract: Examples provide a system that includes one or more processors, that when operational, are to: based on content in a request being within a permitted range for a virtualized execution environment, transfer the request from the virtualized execution environment to reserve one or more device resources independent from causing a virtual machine exit to request to reserve one or more device resources. In some examples, the transfer comprises a write to a register. In some examples, processor-executed microcode is to determine whether content in the request is within a permitted range for the virtualized execution environment.

Abstract: Technologies for dynamically managing data bus bandwidth usage of virtual machines include a network device that includes a data bus, one or more processors coupled to the data bus, and one or more throttled devices coupled to the data bus. Each throttled device is configured to use no more than an amount of bus bandwidth associated with at least one throttle value assigned to the corresponding throttled device. The network device is to assign functions to virtual machines, determine throttle values for each of the throttled devices utilized by the virtual machines to perform their assigned functions, and perform the assigned functions subject to the determined throttle values. Other embodiments are described and claimed.
