  2. Input–output memory management unit - Wikipedia

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

    In computing, an input–output memory management unit (IOMMU) is a memory management unit (MMU) connecting a direct-memory-access–capable (DMA-capable) I/O bus to the main memory. Like a traditional MMU, which translates CPU -visible virtual addresses to physical addresses , the IOMMU maps device-visible virtual addresses (also called device ...

    The vast majority of Intel server chips of the Xeon E3, Xeon E5, and Xeon E7 product lines support VT-d. The first—and least powerful—Xeon to support VT-d was the E5502 launched Q1'09 with two cores at 1.86 GHz on a 45 nm process. [2]

    AMD brands its IOMMU as AMD-Vi. Linux and Windows 10 supports these IOMMUs [6] [7] [8] and can use them to block I/O transactions that have not been allowed. Newer operating systems may take steps to prevent DMA attacks. Recent Linux kernels include the option to disable DMA by FireWire devices while allowing other functions. [9]

    The graphics address remapping table (GART), [1] also known as the graphics aperture remapping table, [2] or graphics translation table (GTT), [3] is an I/O memory management unit (IOMMU) used by Accelerated Graphics Port (AGP) and PCI Express (PCIe) graphics cards.

    IOMMU hardware-based GPU isolation support, increasing security by restricting GPU access to system memory. GPU paravirtualization support, enabling display drivers to provide rendering capabilities to Hyper-V virtualized environments. Brightness, a new interface to support multiple displays that can be set to calibrated nit-based brightness ...

    en.wikipedia.org/wiki/Memory_management_unit

    A 68451 MMU, which could be used with the Motorola 68010. A memory management unit (MMU), sometimes called paged memory management unit (PMMU), [1] is a computer hardware unit that examines all memory references on the memory bus, translating these requests, known as virtual memory addresses, into physical addresses in main memory.

    He also suggests using an air purifier with HEPA filter “to remove allergens and irritants,” and keep your bedroom as dust-free as possible. Control your cough.

  9. 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.
