Parameters for adding a PCIe host bridge to the SSDT.

Fields

index: u32

Unique index of this host bridge.

segment: u16

PCIe segment number.

start_bus: u8

Lowest valid bus number.

end_bus: u8

Highest valid bus number.

ecam_range: MemoryRange

Memory range for ECAM configuration space access.

low_mmio: MemoryRange

Memory range for low MMIO.

high_mmio: MemoryRange

Memory range for high MMIO.

cxl: bool

Whether this host bridge supports CXL.

vnode: Option<u32>

NUMA proximity domain.

preserve_boot_config: bool

When true, emit a _DSM method (“Ignore PCI Boot Configurations”, PCI Firmware Spec §4.6 function 5) instructing the guest OS to keep the firmware-assigned PCI boot configuration (bus numbers and BARs) rather than reprogramming it.
