This implements the VM Generation ID feature by passing a 128-bit GUID to the guest via a fw_cfg blob. Any time the GUID changes, an ACPI notify event is sent to the guest The user interface is a simple device with one parameter: - guid (string, must be "auto" or in UUID format xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx) Signed-off-by: NBen Warren <ben@skyportsystems.com> Reviewed-by: NIgor Mammedov <imammedo@redhat.com> Reviewed-by: NLaszlo Ersek <lersek@redhat.com> Tested-by: NLaszlo Ersek <lersek@redhat.com> Reviewed-by: NMichael S.

This allows them to be centrally initialized and destroyed The "AcpiBuildTables.vmgenid" array will be used to construct the "etc/vmgenid_guid" fw_cfg blob. Its contents will be linked into fw_cfg after being built on the pc_machine_done() -> acpi_setup() -> acpi_build() call path, and dropped without use on the subsequent, guest triggered, acpi_build_update() -> acpi_build() call path.

This is similar to the existing 'add pointer' functionality, but instead of instructing the guest (BIOS or UEFI) to patch memory, it instructs the guest to write the pointer back to QEMU via a writeable fw_cfg file.

That reduces DSDT by 910 bytes when memory hotplug isn't enabled. While doing so drop intermediate variables/arguments passing around ACPI_MEMORY_HOTPLUG_IO_LEN and making it local to memory_hotplug.c, hardcoding it there as it can't change. Also don't pass around ACPI_MEMORY_HOTPLUG_BASE through intermediate variables/arguments where it's not needed. Instead initialize in module static variable when MMIO region is mapped and use that within memory_hotplug.c whenever it's required. That way MMIO base specified only at one place and AML with MMIO would always use the same value. Signed-off-by: NIgor Mammedov <imammedo@redhat.com> Reviewed-by: NMichael S.

For compatibility reasons PC/Q35 will start with legacy CPU hotplug interface by default but with new CPU hotplug AML code since 2.7 machine type. That way legacy firmware that doesn't use QEMU generated ACPI tables will be able to continue using legacy CPU hotplug interface. While new machine type, with firmware supporting QEMU provided ACPI tables, will generate new CPU hotplug AML, which will switch to new CPU hotplug interface when guest OS executes its _INI method on ACPI tables loading.
