16 This device implements the RISC-V IOMMU emulation as recommended by the section
17 "Integrating an IOMMU as a PCIe device" of `iommu1.0.0`_: a PCI device with base

67 considers an IOMMU identified as a Rivos device, i.e. it uses Rivos vendor ID. To
68 use the riscv-iommu-pci device with the existing kernel support we need to emulate
