    摘要： A method and apparatus for transferring registers in transitions between computer environments. An embodiment of a method includes running a first process in a first computer environment and switching to a second process in a second computer environment. The method further provides for transferring a register to the second computer environment. A process for transferring the register is based at least in part on current states of the first computer environment and the second computer environment.

    摘要： A machine-accessible medium may contain program instructions that, when executed by a processor, may cause the processor to perform at least one operation including searching a virtual hash page table (VHPT) using a region identifier and a virtual page number of a virtual address, and a default page size corresponding to the region identifier to locate a virtual address translation in the VHPT. The operation performed may further include searching the VHPT using the region identifier, the virtual page number, and at least one utilized page size to locate a virtual address translation in the VHPT if a virtual address translation is not located during the search of the VHPT using the region identifier, virtual page number, and default page size. The operation performed may also include inserting the located virtual address translation into a translation cache once a virtual address translation is located.

    摘要翻译： 机器可访问介质可以包含程序指令，当处理器执行时，处理器可以使处理器执行至少一个操作，包括使用区域标识符和虚拟地址的虚拟页面号来搜索虚拟散列页表（VHPT） ，以及与区域标识符对应的默认页面大小，以定位VHPT中的虚拟地址转换。 执行的操作可以进一步包括使用区域标识符，虚拟页面号码以及至少一个使用的页面大小来搜索VHPT，以便在VHPT搜索期间如果虚拟地址转换不在位置时定位VHPT中的虚拟地址转换，则使用 区域标识符，虚拟页码和默认页面大小。 所执行的操作还可以包括一旦虚拟地址转换被定位，将定位的虚拟地址转换插入到转换高速缓存中。

    摘要： Systems and methods are disclosed to support partial physical addressing modes on a virtual machine. An example method disclosed herein identifies a change of a first translation mode to a second translation mode on a host hardware platform, the host hardware platform including a processor, the processor further including region registers; identifies an address as cacheable or non-cacheable; saves contents of the region registers for the first translation mode to processor memory; updates content of the region registers corresponding to the second translation mode; identifies a change of the second translation mode to the first translation mode; and populates the region registers with the contents of the saved region registers corresponding to the first translation mode.

    摘要： Host control logic for managing multiple guest virtual machines (VMs) may execute in a system having a processor with at least one region register (RR) and multiple protection key registers (PKRs). The system may also have storage responsive to the processor, with the host control logic stored at least partially in the storage. In one embodiment, the host control logic may reserve at least one of the PKRs, and may maintain virtual region registers (VRRs) to contain region identifier (RIDs) for the guest VMs. When switching context to a guest VM, the host control logic may update the reserved PKR with data to match an RID for the guest VM, and may update the RR with data to match a guest-region identifier (GRID) associated with the guest VM. The RID may also be stored in a key field of a TLB record. Other embodiments are described and claimed.
