EFFICIENT TRANSLATION RELOADS FOR PAGE FAULTS |
摘要 |
Methods to perform an operation comprising identifying, in a software page frame table by an operating system interrupt handler, a physical address of a memory page, wherein the physical address of the memory page is identified based on a virtual segment identifier (VSID) and a page number, wherein the VSID is specified in an interrupt received from a coherent accelerator and wherein the coherent accelerator generated the interrupt in response to a page fault associated with the memory page, and creating, by the operating system interrupt handler, a page table entry in a hardware page table associating the VSID and the page number with the physical address of the memory page, wherein creating the page table entry resolves the page fault. |
