In linux kernel since version 5.4.290 (release Date: 2025-02-01)
Support for implementations of the RISC-V IOMMU architecture that
complements the RISC-V MMU capabilities, providing similar address
translation and protection functions for accesses from I/O devices.
Say Y here if your SoC includes an IOMMU device implementing
the RISC-V IOMMU architecture.
