The embodiment of the invention discloses a task processing method and device based on a virtual processor, a medium and equipment, and the method comprises the steps: generating an interrupt request signal by a virtual timer under the condition that a physical processor corresponding to a virtual machine is in a first mode; the physical processor obtains the interrupt request signal and injects virtual interrupt information corresponding to the interrupt request signal into a virtual processor corresponding to the virtual machine; the virtual processor responds to the virtual interrupt information and executes a processing task corresponding to the virtual interrupt information, and the virtual processor represents processor resources distributed for the virtual machine in the physical processor. According to the embodiment of the invention, the performance overhead generated by storing and recovering the context information of the system timer can be avoided or reduced.

Interpretative execution is performed by a physical processor of a computing environment for a virtual processor executing on the physical processor. The performing interpretative execution includes obtaining an order code indicating an action to be taken for the virtual processor and accessing a shadow state description of the virtual processor to obtain an original state description origin. The original state description origin indicates the location of an original state description of the virtual processor, and the original state description includes state information of the virtual processor. An action is performed using an indicator of the state information of the virtual processor. The indicator is selected based on the order code, and the action is performed by the physical processor on behalf of the virtual processor.

The disclosed system may include a user device with (1) a first module, which performs a first functionality, and (2) a second module, which performs a second functionality, (3) a physical processor, and (4) physical memory including computer-executable instructions that cause the physical processor to (i) determine that a change in a range of frequency, being used by the first module, has resulted, or will result, in interference between the first module's changed range of frequency and a range of frequency being used by the second module, and (ii) in response to the determining that the change in the range of frequency has resulted in the interference, change the range of the frequency being used by the second module to a new range of frequency that does not interfere with the first module's changed range of frequency. Various other wearable devices, apparatuses, and methods of manufacturing are also disclosed.

Method, systems, and computer program products for managing a processor power management feature on behalf of a virtual machine (VM). A device may determine that a VM operating at a computer system possesses a power management entitlement. The device may identify an architectural power management feature available at a physical processor core of a processor system. The physical processor core is associated with a virtual processor core of the VM. Based on the VM possessing the power management entitlement, the device may present an interface to the VM. The interface exposes the architectural power management feature to the VM. The device may identify a request from the VM to modify a state of the architectural power management feature. Based on the request, the device may modify the state of the architectural power management feature at the physical processor core.
