摘要
For a current context in control of a processor requesting access to a particular address, a translation lookaside buffer (TLB) controller specifies a virtual address with a logical partition identifier value indicating a privilege setting of the current context, a process identifier value indicating whether the address is within shared address space, and an effective address comprising at least a portion of the particular address. In response to the virtual address not matching at least one entry within a TLB comprising at least one entry stored for at least one previous translation of at least one previous address, the TLB controller translates the virtual address into a real page number using at least one page table and adding a new entry to the TLB with the virtual address and the real page number, wherein each at least one entry within the TLB identifies a separate privilege setting from among a plurality of privilege settings and a separate indicator of whether the address is within the shared address space.
