Abstract
Methods, systems, and apparatuses relating to sharing translation lookaside buffer entries are described. In one embodiment, a processor includes one or more cores to execute a plurality of threads, a translation lookaside buffer comprising a plurality of entries, each entry comprising a virtual address to physical address translation and a plurality of bit positions, and each set bit of the plurality of bit positions in each entry indicating that the virtual address to physical address translation is valid for a respective thread of the plurality of threads, and a memory management circuit to clear all set bits for a thread by asserting a reset command to a respective reset port of the translation lookaside buffer for the thread, wherein the translation lookaside buffer comprises a separate reset port for each of the plurality of threads.
