摘要： A method of walking page tables includes comparing a virtual address to a plurality of virtual address bit segments to identify a match. Each virtual address bit segment is associated with a page table level that has a page table base address. A designated page table base address is received in response to the match. The page table walk starts at the designated page table, thereby skipping over earlier page tables.
摘要翻译：步行页表的方法包括将虚拟地址与多个虚拟地址位段进行比较以识别匹配。每个虚拟地址位段与具有页表基址的页表级相关联。响应于匹配，接收到指定的页表基地址。页表步行从指定的页表开始，从而跳过较早的页表。

摘要： A computer readable storage medium includes executable instructions to define a processor with guest mode control registers supporting guest mode operating behavior defined by guest context specified in the guest mode control registers. The guest mode control registers include a control bit to specify a guest access blocked register state and a shared register state. Root mode control registers support root mode operating behavior defined by root context specified in the root mode control registers. The root mode control registers include control bits to enable replicated register state access and shared register state access. The guest context and the root context support virtualization of hardware resources such that multiple operating systems supporting multiple applications are executed by the hardware resources.
