Latest Patents

Cheng Chun Tu holds a patent titled "Safe execution of virtual machine callbacks in a hypervisor." This patent describes a method by which a hypervisor communicates with a guest operating system running in a virtual machine. The communication is facilitated through hyper-callbacks that are tailored to the specific guest operating system and are triggered by various events. The functions involved are modified to ensure safe execution and limited access to the guest operating system. Furthermore, these functions are converted to byte code that corresponds to a simplified CPU and memory model, undergoing safety checks by the hypervisor upon registration. This innovative approach allows the hypervisor to execute functions without context switching, thereby enhancing operations such as page reclamation, virtual CPU scheduling, I/O operations, and tracing of the guest operating system.
