2015-06-23hw/pci-bridge: introduce "shpc" propertyLaszlo Ersek
In the PCI expander bridge, we will want to disable those features of pci-bridge that relate to SHPC (standard hotplug controller): - SHPC bar and underlying MemoryRegion - interrupt (INTx or MSI) - effective hotplug callbacks - other SHPC hooks (initialization, cleanup, migration etc) Introduce a new feature request bit in the PCIBridgeDev.flags field, and turn off the above if the bit is explicitly cleared.

2015-06-23hw/pci-bridge: expose _test parameter in SHPC_VMSTATE()Laszlo Ersek
Change the signature of the function-like macro SHPC_VMSTATE(), so that we can produce and expect this field conditionally in the migration stream, starting with an upcoming patch. Cc: Michael S.

2015-02-16pci: split shpc_cleanup and shpc_freePaolo Bonzini
object_unparent should not be called until the parent device is going to be destroyed. Only remove the capability and do memory_region_del_subregion at unrealize time. Freeing the data structures is left in shpc_free, to be called from the instance_finalize callback. Acked-by: Michael S.

2014-10-15qdev: HotplugHandler: Rename unplug callback to unplug_requestIgor Mammedov
'HotplugHandler.unplug' callback is currently used as async call to issue unplug request for device that implements it. Renaming 'unplug' callback to 'unplug_request' should help to avoid confusion about what callback does and would allow to introduce 'unplug' callback that would perform actual device removal when guest is ready for it.

2014-02-10pci/shpc: convert SHPC hotplug to use hotplug-handler APIIgor Mammedov
Split shpc_device_hotplug() into hotplug/unplug callbacks and register them as "hotplug-handler" interface implementation of PCI_BRIDGE_DEV device. Replace pci_bus_hotplug() wiring with setting link on PCI BUS "hotplug-handler" property to PCI_BRIDGE_DEV device. Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S.
