IOMMU (input/output memory management unit)



 Currently four x86-64 PCI-DMA mapping implementations exist:

 Multiple x86-64 PCI-DMA mapping implementations exist, for example:



   1. <arch/x86_64/kernel/pci-nommu.c>: use no hardware/software IOMMU at all

   1. <lib/dma-direct.c>: use no hardware/software IOMMU at all

      (e.g. because you have < 3 GB memory).
