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]
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 ...

Memory-mapped I/O is preferred in IA-32 and x86-64 based architectures because the instructions that perform port-based I/O are limited to one register: EAX, AX, and AL are the only registers that data can be moved into or out of, and either a byte-sized immediate value in the instruction or a value in register DX determines which port is the source or destination port of the transfer.

this section has lots of incorrect information in it, for example GA-990FXA-UD3 completely supports IOMMU and ESXi works just fine with it my board isn't even a REV3.0 just a rev1.1. Yes i am doing IOMMU specific things, like USB/RAID PCI card pass through.
He also pledged to use tariffs as a negotiating tool on other countries, including, for example, Denmark — putting pressure on the European nation to give control of Greenland to the United States.
