In linux kernel since version 6.13 (release Date: 2025-01-19)
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.
