Struct devices::pci::pci_root::PciRootMmioState

struct PciRootMmioState {
    mappings: BTreeMap<u32, Option<(SharedMemory, MemoryMapping)>>,
    base: GuestAddress,
    register_bit_num: usize,
}

Fields

mappings: BTreeMap<u32, Option<(SharedMemory, MemoryMapping)>>

Contains pages mapped read-only into the guest’s MMIO space corresponding to the PCI configuration space. Keys are the offset in number of pages from the start of MMIO space. If a particular value is None, then at least one attached device on that page does not support read-only mapped MMIO.

base: GuestAddress

Base address of the PCI configuration space’s MMIO region.

register_bit_num: usize

Number of bits in the address space of a particular function’s MMIO space.
