![]() This device models the RISC-V IOMMU as a sysbus device. The same design decisions taken in the riscv-iommu-pci device were kept, namely the existence of 4 vectors are available for each interrupt cause. The WSIs are emitted using the input of the s->notify() callback as a index to an IRQ list. The IRQ list starts at 'base_irq' and goes until base_irq + 3. This means that boards must have 4 contiguous IRQ lines available, starting from 'base_irq'.
