Abstract: Examples of the present disclosure describe systems and methods for the non-disruptive servicing of components of a user mode process. In examples, a user mode process comprises multiple components, each encapsulating a distinct piece of functionality. A replacement component is loaded and initialized. The replacement component is validated to ensure that the required dependencies of the replacement component are satisfied by the other components of the user mode process. The component to be serviced and the components having dependencies on the component to be serviced are suspended to enable a snapshot of the runtime state of the component to be serviced to be captured. The runtime state is copied to the replacement component and the components having dependencies on the component to be serviced are updated to reference the replacement component. The replacement component is executed and the suspended components are resumed. The component to be serviced is unloaded.

Abstract: Systems and methods for determining and reporting actual utilization of a core of a central processing unit (CPU) of a host. Prior to implementation of aspects of the present disclosure, running a poll querying endpoints of a process for work appears to the host's operating system as busy work (e.g., taking full use of the core for the poll duration). However, only a percentage of the duration of the poll is used to process a task of the process, where the remaining duration of the poll is spent querying the endpoints (idle time) and the core is not performing a task. Accordingly, a core utilization reporting system and method automatically detects the processing time of the tasks of a process, determines actual CPU utilization of the core based on a percentage of the time the core is busy polling (doing effectively no work) versus doing actual work (processing a task).
