You can compile a Linux kernel without MMU support on most processor architectures, including x86. However, because this is a rare configuration only for users who know what they are doing, the option is not included in the menu displayed by make menuconfig, make xconfig and the like, except on a few architectures for embedded devices where the lack of MMU is relatively common.

Sep 11, 2007 · There is currently high-end branded server hardware that support this, but no desktop machines support IOMMU, AFAIK. An example IOMMU is the AGP and PCI Express graphics cards. More about IOMMU. According to wikipedia: The IOMMU or input/output memory management unit is a computer memory management unit (MMU) that connects a DMA-capable I/O bus ...

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. Many or most Xeons subsequent to this support VT-d.

A memory management unit (MMU), sometimes called paged memory management unit (PMMU), is a computer hardware unit having all memory references passed through itself, primarily performing the translation of virtual memory addresses to physical addresses.. An MMU effectively performs virtual memory management, handling at the same time memory protection, cache control, bus arbitration …
