Webx86 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. 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 sam…

Non-ideal MMU caches degrade performance by as much as 10-17%. Surprisingly, we find (because we use a real system) that real MMU cache sizes differ from those assumed in past simulation-based studies [2]. Second, we propose a hardware/software coalescing tech-nique to reduce MMU cache misses. In this …
The advantages of having an IOMMU, compared to direct physical addressing of the memory (DMA), include : • Large regions of memory can be allocated without the need to be contiguous in physical memory – the IOMMU maps contiguous virtual addresses to the underlying fragmented physical addresses. Thus, the use of vectored I/O (scatter-gather lists) can sometimes be avoided.
