Add a Rust version of qdev_init_clock_in, which can be used in instance_init. There are a couple differences with the C version: - in Rust the object keeps its own reference to the clock (in addition to the one embedded in the NamedClockList), and the reference is dropped automatically by instance_finalize(); this is encoded in the signature of DeviceClassMethods::init_clock_in, which makes the lifetime of the clock independent of that of the object it holds. This goes unnoticed in the C version and is due to the existence of aliases. - also, anything that happens during instance_init uses the pinned_init framework to operate on a partially initialized object, and is done through class methods (i.e. through DeviceClassMethods rather than DeviceMethods) because the device does not exist yet. Therefore, Rust code *must* create clocks from instance_init, which is stricter than C. Reviewed-by: Zhao Liu <zhao1.liu@intel.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> |
