摘要： Embodiments of apparatuses, methods, and systems for decoding a virtual machine control structure identification are disclosed. In one embodiment, an apparatus includes a virtual machine control structure to decode a virtual machine control structure identification data. The virtual machine control structure identification data is decoded into an address of a virtual machine control structure field and an offset. The offset is to help identify a micro-operation associated with a virtual machine architecture instruction to be executed.

摘要： Methods and systems to provide support for single stepping a virtual machine in a virtual machine environment are disclosed. An exemplary method may include receiving a request to transition control to a virtual machine (VM) from a virtual machine monitor (VMM), determining that a single-stepping indicator is set to a single stepping value, and transitioning control to the VM. Further, if an execution of a first instruction in the VM completes successfully, control is transitioned to the VMM following the successful completion of the execution of the first instruction.

摘要： A method and apparatus is described herein for accessing a physical memory location referenced by a physical address with a processor. The processor fetches/receives instructions with references to virtual memory addresses and/or references to physical addresses. Translation logic translates the virtual memory addresses to physical addresses and provides the physical addresses to a common interface. Physical addressing logic decodes references to physical addresses and provides the physical addresses to a common interface based on a memory type stored by the physical addressing logic.

摘要： In one embodiment of the present invention, a method includes switching between a first address space and a second address space, determining if the second address space exists in a list of address spaces; and maintaining entries of the first address space in a translation buffer after the switching. In such manner, overhead associated with such a context switch may be reduced.
