[Qemu-devel] [PATCH v5 0/9] pci: multi-function bit fixes


From: Isaku Yamahata
Subject: [Qemu-devel] [PATCH v5 0/9] pci: multi-function bit fixes
Date: Wed, 23 Jun 2010 16:15:24 +0900

Maing changes v4 -> v5:
- split up/reorder patches for bisectability and testability
- stype fixes.

patch description:

When pci devices are populated as multi-function,
OS can fail to probe function > 0. It's because multi function
bit of header type register in configuration space isn't set,
so OS probes only function 0 skipping function > 0 as optimization.

This patch set make qemu set multi function bit when function > 0 
is populated.

Changes v3 -> v4:
- introduced multifunction property and add validation check to catch
  user operation errors.
- some more clean up.


Isaku Yamahata (9):
  pci: use PCI_DEVFN() where appropriate.
  pci: insert assert that auto-assigned-address function is single
    function device.
  pci: don't overwrite multi functio bit in pci header type.
  pci: remove PCIDeviceInfo::header_type
  qdev: implement qdev_prop_set_bit().
  pci: introduce multifunction property.
  pci: set multifunction property for normal device.
  pci_bridge: make pci bridge aware of pci multi function bit.
  pci: set PCI multi-function bit appropriately.
