Methods, Systems, And Computer Readable Media For Performing Page Fault Handling
Abstract
Methods, systems, and computer readable media for performing page fault handling are disclosed. According to one method, the method includes: after a translation lookaside buffer (TLB) miss associated with a virtual memory page occurs, identifying, in a page table, a page table entry (PTE) associated with the virtual memory page; determining, using a first indicator in the PTE, that the virtual memory page is not present in a main memory; determining, using a second indicator in the PTE, that the virtual memory page is associated with a valid memory address and that the virtual memory page is capable of using pre-allocated pages; obtaining, from a pre-allocation table, a page frame number associated with a pre-allocated page; and updating the PTE to indicate the page frame number.
