Abstract
Techniques for improving translation lookaside buffer (TLB) operation are disclosed. A particular entry of the TLB is to be updated with data associated with a large page size. The TLB updates replacement policy data for that TLB entry for that large page size to indicate that the TLB entry is not the least-recently-used. To prevent smaller pages from evicting the TLB entry for the large page size, the TLB also updates replacement policy data for that TLB entry for the smaller page size to indicate that the TLB entry is not the least-recently-used.
