MULTI-PAGE CHECK HINTS FOR SELECTIVE CHECKING OF PROTECTED CONTAINER PAGE VERSUS REGULAR PAGE TYPE INDICATIONS FOR PAGES OF CONVERTIBLE MEMORY

摘要

A processor of an aspect includes at least one translation lookaside buffer (TLB) and a memory management unit (MMU). Each TLB is to store translations of logical addresses to corresponding physical addresses. The MMU, in response to a miss in the at least one TLB for a translation of a first logical address to a corresponding physical address, is to check for a multi-page protected container page versus regular page (P/R) check hint. If the multi-page P/R check hint is found, then the MMU is to check a P/R indication. If the multi-page P/R check hint is not found, then the MMU does not check the P/R indication. Other processors, methods, and systems are also disclosed.

1. A processor comprising:
at least one translation lookaside buffer (TLB), each TLB to store translations of logical addresses to corresponding physical addresses; and a memory management unit (MMU), the MMU, in response to a miss in the at least one TLB for a translation of a first logical address to a corresponding physical address, to:
check for a multi-page protected container page versus regular page (P/R) check hint;if the multi-page P/R check hint is found, then check a P/R indication; andif the multi-page P/R check hint is not found, then do not check the P/R indication.
