History

Dr. David Alan Gilbert a83c284490 acpi: fix acpi_index migration vmstate_acpi_pcihp_use_acpi_index() was expecting AcpiPciHpState as state but it actually received PIIX4PMState, because VMSTATE_PCI_HOTPLUG is a macro and not another struct. So it ended up accessing random pointer, which resulted in 'false' return value and acpi_index field wasn't ever sent. However in 7.0 that pointer de-references to value > 0, and destination QEMU starts to expect the field which isn't sent in migratioon stream from older QEMU (6.2 and older). As result migration fails with: qemu-system-x86_64: Missing section footer for 0000:00:01.3/piix4_pm qemu-system-x86_64: load of migration failed: Invalid argument In addition with QEMU-6.2, destination due to not expected state, also never expects the acpi_index field in migration stream. Q35 is not affected as it always sends/expects the field as long as acpi based PCI hotplug is enabled. Fix issue by introducing compat knob to never send/expect acpi_index in migration stream for 6.2 and older PC machine types and always send it for 7.0 and newer PC machine types.
