  2. Intel 5-level paging - Wikipedia

    en.wikipedia.org/wiki/Intel_5-level_paging

    Intel 5-level paging, referred to simply as 5-level paging in Intel documents, is a processor extension for the x86-64 line of processors. [1]: 11 It extends the size of virtual addresses from 48 bits to 57 bits by adding an additional level to x86-64's multilevel page tables, increasing the addressable virtual memory from 256 TiB to 128 PiB.

  3. Second Level Address Translation - Wikipedia

    en.wikipedia.org/wiki/Second_Level_Address...

    A hardware page table walker can treat the additional translation layer almost like adding levels to the page table. Using SLAT and multilevel page tables, the number of levels needed to be walked to find the translation doubles when the guest-physical address is the same size as the guest-virtual address and the same size pages are used.

    Nested page tables can be implemented to increase the performance of hardware virtualization. By providing hardware support for page-table virtualization, the need to emulate is greatly reduced. For x86 virtualization the current choices are Intel's Extended Page Table feature and AMD's Rapid Virtualization Indexing feature.

  5. Physical Address Extension - Wikipedia

    en.wikipedia.org/wiki/Physical_Address_Extension

    Supporting 64 bit addresses in the page-table is a significant change as this enables two changes to the processor addressing. Firstly, the page table walker, which uses physical addresses to access the page table and directory, can now access physical addresses greater than the 32-bit physical addresses supported in systems without PAE.

  6. Translation lookaside buffer - Wikipedia

    en.wikipedia.org/wiki/Translation_lookaside_buffer

    If it is a TLB miss, then the CPU checks the page table for the page table entry. If the present bit is set, then the page is in main memory, and the processor can retrieve the frame number from the page-table entry to form the physical address. [6] The processor also updates the TLB to include the new page-table entry.

  9. Page Size Extension - Wikipedia

    en.wikipedia.org/wiki/Page_Size_Extension

    The entries in the page directory have an additional flag, in bit 7, named PS (for page size). This flag was ignored without PSE, but now, the page-directory entry with PS set to 1 does not point to a page table, but to a single large 4 MiB page. The page-directory entry with PS set to 0 behaves as without PSE.
