Abstract
A method includes configuring a memory for storing a kernel page table and a user page table to low-order address space, and reserving high-order address space, obtaining register configuration information of a kernel page table of a second operating system from the second operating system, and configuring a register of the high-order address space of a first operating system based on the register configuration information of the kernel page table of the second operating system such that the high-order address space is enabled to directly access a kernel resource of the second operating system.
