PCI Subsystem

What we have ported so far

  • PCI data structures such as pci_dev, pci_bus, and so on.
  • Mechanism to scan bus and build data structures during boot. Performed by pci_scan_root_bus(), and most code is in driver/pci/probe.c

Unfinished business

  • Ways to go through all PCI device.
  • pci_init_capabilities(): for each PCI device
  • pci_fixup_device(): a lot quicks, maybe not useful
  • pcie_aspm_init_link_state(): PCIe link state
  • pci_iov_bus_range: all SR-IOV support
