  2. System Management Mode - Wikipedia

    en.wikipedia.org/wiki/System_Management_Mode

    System Management Mode (SMM, sometimes called ring −2 in reference to protection rings) [1] [2] is an operating mode of x86 central processor units (CPUs) in which all normal execution, including the operating system, is suspended.

  3. Protected mode - Wikipedia

    en.wikipedia.org/wiki/Protected_mode

    In computing, protected mode, also called protected virtual address mode, [1] is an operational mode of x86-compatible central processing units (CPUs). It allows system software to use features such as segmentation, virtual memory, paging and safe multi-tasking designed to increase an operating system's control over application software.

  4. Intel vPro - Wikipedia

    en.wikipedia.org/wiki/Intel_vPro

    Intel AMT is the set of management and security features built into vPro PCs that makes it easier for a sys-admin to monitor, maintain, secure, and service PCs. [11] Intel AMT (the management technology) is sometimes mistaken for being the same as Intel vPro (the PC "platform"), because AMT is one of the most visible technologies of an Intel vPro-based PC.

  5. Trusted Execution Technology - Wikipedia

    en.wikipedia.org/wiki/Trusted_Execution_Technology

    The processor validates the signature and integrity of the signed module before executing it. The ACM then measures the first BIOS code module, which can make additional measurements. The measurements of the ACM and BIOS code modules are extended to PCR0, which is said to hold the static core root of trust measurement (CRTM) as well as the ...

    Windows 11 is built with a scheduler that is able to recognise the information provided by the Thread Director, and delegates the running programmes accordingly to the relevant CPU cores.

  7. 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.

  8. Hyper-V - Wikipedia

    en.wikipedia.org/wiki/Hyper-V

    Hyper-V is a native hypervisor developed by Microsoft; it can create virtual machines on x86-64 systems running Windows. [1] It is included in Pro and Enterprise editions of Windows NT (since Windows 8) as an optional feature to be manually enabled. [2]

  9. Input–output memory management unit - Wikipedia

    en.wikipedia.org/wiki/Input–output_memory...

    The memory protection is based on the fact that OS running on the CPU (see figure) exclusively controls both the MMU and the IOMMU. The devices are physically unable to circumvent or corrupt configured memory management tables. In virtualization, guest operating systems can use hardware that is not specifically made for virtualization. Higher ...
