[Qemu-devel] [PATCH v2 0/4] pcie: Add support for Single Root I/O Virtualization

[Knut Omang]

This patch set implements generic support for SR/IOV as an extension to the 
core PCIe functionality, similar to the way other capabilities such as AER
is implemented. 

There is no implementation of any device that provides
SR/IOV support included, but I have implemented a test 
example which can be found together with this patch set here:

  git://github.com/knuto/qemu.git sriov_patches_v2

Testing with this example device documented here:

  http://lists.nongnu.org/archive/html/qemu-devel/2014-08/msg05110.html 

Changes since v1:
  - Rebased on top of latest master, eliminating prereqs.
  - Implement proper support for VF_STRIDE, VF_OFFSET and SUP_PGSIZE
    Time better spent fixing it than explaining what the previous 
    limitations were.
    - Added new first patch to fix pci bug related to this
  - Split out patch to pci_default_config_write to a separate patch 2
    to highlight bug fix.
  - Refactored out logic into new source files 
    hw/pci/pcie_sriov.c include/hw/pci/pcie_sriov.h
    similar to pcie_aer.c/h.
  - Rename functions and introduce structs to better separate 
    pf and vf functionality.
  - Replaced is_vf member with pci_is_vf() function abstraction
  - Fix numerous syntax, whitespace and comment issues
    according to Michael's review.
  - Fix memory leaks.
  - Removed igb example device - a rebased version available
    on github instead.
