Abstract
Some embodiments include a method that can store a first physical address in a first entry in a translation lookaside buffer (TLB). The method can configure a first marker in the first entry in the TLB to indicate that hit suppression is allowed for the first entry. The method can detect a multi-processor coherency operation that will cause hit suppression for certain entries in a TLB, and cause purging of certain entries in the TLB. The method can translate a second virtual address for a second instruction into a second physical address. The method can store the second physical address in a second entry. The method can configure a second marker in the second entry in the TLB to indicate that the hit suppression is not allowed for the second entry in the TLB, and that the purging is not allowed for the second entry in the TLB.
