Support for RISC-V IOMMU spec v1.0.1 (ratified) https://github.com/riscv-non-isa/riscv-iommu Supports translation for PCI devices only. Supports 1 or 2-level device-directory-table (DDT). Supports SV39 and SV48 virtual memory system (on per-device basis). Supports both "standard" and "extended" device-context (DC) structure. Supports "bypass" mode to disable translation for a particular device. Supports WSI (Wire-Signalled Interrupts) only. This includes both PCI-bus and FDT attachment drivers. Note in case of PCI-bus attachment, interrupts are not available. In this case no error report is provided in case of translation fault. Otherwise interrupts are not needed.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
