I agree that there's a performance tradeoff with current generation hardware and ingerfaces, but it wouldn't be fair to single out a single IOMMU implementation ;=)
config DMAR bool "Support for DMA Remapping Devices (EXPERIMENTAL)" depends on X86_64 && PCI_MSI && ACPI && EXPERIMENTAL help DMA remapping (DMAR) devices support enables independent address translations for Direct Memory Access (DMA) from devices. These DMA remapping devices are reported via ACPI tables and include PCI device scope covered by these DMA remapping devices.
