Patent 10055248 was granted and assigned to Red Hat on August, 2018 by the United States Patent and Trademark Office.
Systems and methods for scheduling virtual processors via memory monitoring are disclosed. In one implementation, a hypervisor running on a host computer system may detect a task switch event associated with a virtual processor running on a physical processor of the host computer system. The hypervisor may test a polling flag residing in a memory accessible by the guest software running on the virtual processor and set the polling flag to a non-polling state. The hypervisor may then process the task switch event.
