[Qemu-devel] [PATCH 00/13] pci: Cleanups & preparations for KVM device assignment

[Jan Kiszka <jan.kiszka@siemens.com>]

Besides some smaller cleanups, this series has two main topics:

The first is the already posted PCI IRQ routing lookup and notifier. The
lookup has been based on the cached routing Michael suggested also for
emulated devices. However, this still introduces a new callback and
keeps the bus irq_count untouched due to the vmstate complications when
changing it.

The second half refactors PCI device address parsing, introducing an
universal parsing function. It is then used to provide a new qdev
property that accepts fully qualified PCI addresses (domain:bus:device.
function).

These two major changes will help refactoring PCI device assignment in
qemu-kvm in order to upstream it soon. But also the upcoming VFIO-based
assignment should be able to benefit.

Jan Kiszka (13):
  pci: Refactor pci_change_irq_level
  pci: Fold pci_bus_new_inplace into pci_bus_new
  pci: Introduce cached device INTx routing
  pci: Rename map_irq to route_pin
  pci: Add pci_device_route_intx_to_irq
  pci: Add INTx routing notifier
  pci: Make domain and bus unsigned in pci_read_devaddr
  pci: Export pci_parse_devaddr instead of pci_read_devaddr
  pci: Introduce and apply PCIDeviceAddress
  pci: Fix coding style of pci_parse_devaddr
  Move pci_parse_devaddr to qdev-properties
  qdev-properties: Use qemu_parse_pci_devaddr for pci-devfn property
  qdev-properties: Add pci-devaddr property
