[PATCH v9 0/7] PCI: Linux kernel SR-IOV support

[Yu Zhao]

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

Physical Function driver for Intel 82576 NIC (based on drivers/net/igb/)
will come soon.

Major changes from v8 to 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 (7):
  PCI: initialize and release SR-IOV capability
  PCI: restore saved SR-IOV state
  PCI: reserve bus range for SR-IOV device
  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
