Abstract
Methods, devices, and instructions for performing a reverse translation lookaside buffer (TLB) look-up using a physical address input, including obtaining with a first processor the physical address input, wherein the physical address input indicates a physical address corresponding to a shared memory, obtaining a first mask associated with a first virtual address from a first TLB entry within a TLB associated with the first processor, wherein the obtained first mask is a bit pattern, obtaining from the first TLB entry a first page frame number associated with the shared memory, applying the obtained first mask to the obtained first page frame number to generate a first value, applying the obtained first mask to the obtained physical address input to generate a second value, and comparing the first value and the second value to determine whether the first value and the second value match.
