When the application falls into the root mode from a non-root mode, that is, when it is trapped in the operating system kernel due to active or passive (such as an exception), the page table data structure needs to be synchronized to the original state. The page table structure managed by the kernel. Since the page table is a discrete mapping of virtual memory and physical memory, when copying the page table data structure, for the physical memory already mapped in the kernel page table, it is necessary to lock in the kernel, and not to swap out The items that are not yet filled in the page table are managed by the user state system service function library according to the application request, the execution process state, and the reserved physical memory.

And allocate physical memory, and finally return; 2) The second part of the function is: user state page fault exception handling, wherein the page fault exception refers to the hardware exception triggered by accessing the virtual address when the mapping entry in the page table does not exist. Existing Linux and most other operating systems are done through the kernel's exception handling functions, but this is In an embodiment of the common application provide temporary update existing hardware initialization exception handler, and the VMCS data structure is provided, such that when a page fault exception occurs, hard The device will throw the page fault exception to the user state, and is processed by the user state page fault exception handler function in the user space system service function library.
