    en.wikipedia.org/wiki/Virtual_8086_mode

    AMD-V can do virtual 8086 mode in guests, too, but it can also just run the guest in "paged real mode" using the following steps: you create a SVM (Secure Virtual Machine) mode guest with CR0.PE=0, but CR0.PG=1 (that is, with protected mode disabled but paging enabled), which is ordinarily impossible, but is allowed for SVM guests if the host ...

  5. x86 virtualization - Wikipedia

    en.wikipedia.org/wiki/X86_virtualization

    x86 virtualization is the use of hardware-assisted virtualization capabilities on an x86/x86-64 CPU.. In the late 1990s x86 virtualization was achieved by complex software techniques, necessary to compensate for the processor's lack of hardware-assisted virtualization capabilities while attaining reasonable performance.

    Zen 3 was released on November 5, 2020, [30] using a more matured 7 nm manufacturing process, powering Ryzen 5000 series CPUs and APUs [30] (codename "Vermeer" (CPU) and "Cézanne" (APU)) and Epyc processors (codename "Milan"). Zen 3's main performance gain over Zen 2 is the introduction of a unified CCX, which means that each core chiplet is ...

    It is only available with the long mode (64-bit mode) or legacy Physical Address Extension (PAE) page-table formats, but not x86's original 32-bit page table format because page table entries in that format lack the 64th bit used to disable and enable execution. Windows XP SP2 and later support Data Execution Prevention (DEP).

    Rapid Virtualization Indexing (RVI), known as Nested Page Tables (NPT) during its development, is an AMD second generation hardware-assisted virtualization technology for the processor memory management unit (MMU). [1] [2] RVI was introduced in the third generation of Opteron processors, code name Barcelona. [3]
