2009-03-20PCI: handle SR-IOV Virtual Function MigrationYu Zhao
Add or remove a Virtual Function after receiving a Migrate In or Out Request. Reviewed-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: Yu Zhao <yu.zhao@intel.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
2009-03-20PCI: add SR-IOV API for Physical Function driverYu Zhao
Add or remove the Virtual Function when the SR-IOV is enabled or disabled by the device driver. This can happen anytime rather than only at the device probe stage.

2009-03-20PCI: reserve bus range for SR-IOV deviceYu Zhao
Reserve the bus number range used by the Virtual Function when pcibios_assign_all_busses() returns true. Reviewed-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: Yu Zhao <yu.zhao@intel.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
2009-03-20PCI: restore saved SR-IOV stateYu Zhao
Restore the volatile registers in the SR-IOV capability after the D3->D0 transition. Reviewed-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: Yu Zhao <yu.zhao@intel.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
2009-03-20PCI: initialize and release SR-IOV capabilityYu Zhao
If a device has the SR-IOV capability, initialize it (set the ARI Capable Hierarchy in the lowest numbered PF if necessary; calculate the System Page Size for the VF MMIO, probe the VF Offset, Stride and BARs). A lock for the VF bus allocation is also initialized if a PF is the lowest numbered PF.
