Function iommu::init

pub fn init(
    host_address_width: u8,
    pci_segment_number: u16,
    register_base_address: PhysicalAddress,
    page_table: &mut PageTable
) -> Result<(), &'static str>

Initialize the IOMMU hardware.

Currently this just sets up basic structures and prints out information about the IOMMU; it doesn’t actually create any I/O device page tables.

Arguments

• host_address_width: number of address bits available for DMA
• pci_segment_number: PCI segment associated with this IOMMU
• register_base_address: base address of register set
• page_table: page table to install mapping
