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.
See Intel 64 and IA-32 Architectures Software Developer's Manual. 23: CET: Control-flow Enforcement Technology: If set, enables control-flow enforcement technology. [16]: 2–19 24: PKS: Enable Protection Keys for Supervisor-Mode Pages: If set, each supervisor-mode linear address is associated with a protection key when 4-level or 5-level ...
PAE was first introduced by Intel in the Pentium Pro, and later by AMD in the Athlon processor. [2] It defines a page table hierarchy of three levels (instead of two), with table entries of 64 bits each instead of 32, allowing these CPUs to directly access a physical address space larger than 4 gigabytes (2 32 bytes).
To use virtual 8086 mode, an operating system sets up a virtual 8086 mode monitor, which is a program that manages the real-mode program and emulates or filters access to system hardware and software resources. The monitor must run at privilege level 0 and in protected mode. Only the 8086 program runs in VM86 mode and at privilege level 3.
Extended Page Tables (EPT) is an Intel second-generation x86 virtualization technology for the memory management unit (MMU). EPT support is found in Intel's Core i3, Core i5, Core i7 and Core i9 CPUs, among others. [6] It is also found in some newer VIA CPUs.
