This crate is based on the crosvm devices/src/pci implementation from 107edb3e
We introduced a few changes:
- This one is a standalone crate. The device crate does not carry any
PCI specific bits.
- Simplified PCI root configuration. We only carry a pointer to a
PciConfiguration, not a wrapper around it.
- Simplified BAR allocation API. All BARs from the PciDevice instance
must be generated at once through the PciDevice.allocate_bars()
method.
- The PCI BARs are added to the MMIO bus from the PciRoot add_device()
method.
