PROVISION OF DIRECT ACCESS FROM VIRTUAL ENVIRONMENT TO HARDWARE

摘要

PROBLEM TO BE SOLVED: To allow a device driver within a virtual environment to be communicated correctly with a legacy hardware. SOLUTION: A physical address of a hardware device is mapped within a virtual machine process, in a hypervisor or the hardware serving as a basis, and an extension and other software application operated within the virtual machine process are allowed to have direct access to the hardware device.
