Latest Patents

One of his latest patents is titled "Dynamic Virtual Machine Memory Allocation." This innovative system includes at least one memory device and a processor in communication with the memory device. It features a guest operating system associated with a device driver and an out-of-memory (OOM) handler executing on the processor. The OOM handler is designed to locate a memory device, send an out-of-memory request to the device driver, and receive a response from the memory device. The device driver is then configured to query unusable device memory, request to plug the unusable memory, and report it as now usable memory.

Another significant patent is "Housekeeping Virtual Processor Overcommit for Real-Time Virtualization." This system comprises a hypervisor, virtual machines, and virtual processors. The virtual processors include a real-time virtual processor and a housekeeping virtual processor. The housekeeping virtual processor initiates a non-preemptible task and increments a counter value. Upon completing the task, it decrements the counter value towards the initial value. When the counter reaches the initial value, the housekeeping processor checks a flag set by the hypervisor and executes a hypercall to yield the associated processor.
