[PATCH v12 0/8] PCI: Linux kernel SR-IOV support

[Yu Zhao <yu.zhao@intel.com>]

Greetings,

Following patches are intended to support SR-IOV capability in the
Linux kernel. With these patches, people can turn a PCI device with
the capability into multiple ones from software perspective, which
will benefit KVM and achieve other purposes such as QoS, security,
and etc.

SR-IOV specification can be found at:
  http://www.pcisig.com/members/downloads/specifications/iov/sr-iov1.0_11Sep07.pdf
(it requires membership.)

Devices that support SR-IOV are available from following vendors:

  http://www.myri.com/vlsi/Lanai_Z8ES_Datasheet.pdf
  http://www.neterion.com/products/pdfs/X3100ProductBrief.pdf

The patches to enable the SR-IOV capability of Intel 82576 NIC are
available at (a.k.a Physical Function driver):
  http://patchwork.kernel.org/patch/8063/
  http://patchwork.kernel.org/patch/8064/
  http://patchwork.kernel.org/patch/8065/
  http://patchwork.kernel.org/patch/8066/
And the driver for Intel 82576 Virtual Function are available at:
  http://patchwork.kernel.org/patch/11029/
  http://patchwork.kernel.org/patch/11028/


Major changes from v11 to v12:
  1, fix using garbage entry pointer after the list_for_each (Matthew Wilcox)
  2, use #ifdef around SR-IOV structure in the pci_dev (Matthew Wilcox)
  3, enhance the Kconfig help text for the SR-IOV (Matthew Wilcox)

  v10 to v11:
  1, use pci_setup_device() to setup Virtual Function (Matthew Wilcox)
  2, various coding style fixes (Matthew Wilcox)
  3, wording and grammar fixes (Randy Dunlap)

  v9 -> v10:
  1, minor fix in pci_restore_iov_state().
  2, respin against the latest tree.

  v8 -> v9:
  1, put a might_sleep() into SR-IOV API which sleeps (Andi Kleen)
  2, block user config accesses before clearing VF Enable bit (Matthew Wilcox)

Yu Zhao (8):
  PCI: initialize and release SR-IOV capability
  PCI: restore saved SR-IOV state
  PCI: reserve bus range for SR-IOV device
  PCI: centralize device setup code
  PCI: add SR-IOV API for Physical Function driver
  PCI: handle SR-IOV Virtual Function Migration
  PCI: document SR-IOV sysfs entries
  PCI: manual for SR-IOV user and driver developer
