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： 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.
