CONFIG_IOMMU: IOMMU support

General informations

The Linux kernel configuration item CONFIG_IOMMU:

Help text

Support for full DMA access of devices with 32bit memory access only on systems with more than 3GB. This is usually needed for USB, sound, many IDE/SATA chipsets and some other devices. Provides a driver for the AMD Athlon64/Opteron/Turion/Sempron GART based hardware IOMMU and a software bounce buffer based IOMMU used on Intel systems and as fallback. The code is only active when needed (enough memory and limited device) unless IOMMU_DEBUG or iommu=force is specified too.
