While testing q35 live migration, I found that the migration would abort with
the following error: "Unknown savevm section type 76".
The error is due to this check failing in 'vmstate_load_state()':
while(field->name) {
if ((field->field_exists &&
field->field_exists(opaque, version_id)) ||
(!field->field_exists &&
field->version_id <= version_id)) {
The VMSTATE_PCIE_DEVICE() currently has a 'version_id' set to 2. However,
'version_id' in the above check is 1. And thus we fail to load the pcie device
field. Further the code returns to 'qemu_loadvm_state()' which produces the
error that I saw.
I'm proposing to fix this by simply dropping the 'version_id' field from
VMSTATE_PCIE_DEVICE(). VMSTATE_PCI_DEVICE() defines no such field and further
the vmstate_pcie_device that VMSTATE_PCI_DEVICE() refers to is already
versioned. Thus, any versioning issues could be detected at the vmsd level.
Taking a step back, I think that the 'field->version_id' should be compared
against a saved version number for the field not the 'version_id'. Futhermore,
once vmstate_load_state() is called recursively on another vmsd, the check of:
if (version_id > vmsd->version_id) {
return -EINVAL;
}
Will never fail since version_id is always equal to vmsd->version_id. So I'm
wondering why we aren't storing the vmsd version id of the source in the
migration stream?
This patch also renames the 'name' field of vmstate_pcie_device from:
PCIDevice -> PCIEDevice to differentiate it from vmstate_pci_device.

Simplify logic for hotplug notification, by tracking state of the
logical interrupt condition. We then simply use this variable to make
the interrupt decision, according to spec.
API is made cleaner as we no longer force users to pass in
old slot control value.
Includes fixes by Isaku Yamahata.

This patch implements helper functions for pci express capability
and pci express extended capability allocation.
NOTE: presence detection depends on pci_qdev_init() change.
