2015-03-31qom: Fix object_property_add_alias() with [*]Andreas Färber
Commit 8074264 (qom: Add description field in ObjectProperty struct) introduced property descriptions and copied them for alias properties. Instead of using the caller-supplied property name, use the returned property name for setting the description. This avoids an Error when setting a property description for a property with literal "[*]" that doesn't exist due to automatic property naming in object_property_add().

2015-03-09Generalize QOM publishing of date and time from mc146818rtc.cDavid Gibson
The mc146818rtc driver exposes the current RTC date and time via the "date" property in QOM (which is also aliased to the machine's "rtc-time" property). Currently it uses a custom visitor function rtc_get_date to do this. This patch introduces new helpers to the QOM core to expose struct tm valued properties via a getter function, so that this functionality can be more easily duplicated in other RTC implementations.

2014-03-19qom: Add check() argument to object_property_add_link()Stefan Hajnoczi
There are currently three types of object_property_add_link() callers: 1. The link property may be set at any time. 2. The link property of a DeviceState instance may only be set before realize. 3. The link property may never be set, it is read-only. Something similar can already be achieved with object_property_add_str()'s set() argument. Follow its example and add a check() argument to object_property_add_link(). Also provide default check() functions for case #1 and #2. Case #3 is covered by passing a NULL function pointer.

2014-03-19qom: Make QOM link property unref optionalStefan Hajnoczi
Some object_property_add_link() callers expect property deletion to unref the link property object. Other callers expect to manage the refcount themselves. The former are currently broken and therefore leak the link property object. This patch adds a flags argument to object_property_add_link() so the caller can specify which refcount behavior they require. The new OBJ_PROP_LINK_UNREF_ON_RELEASE flag causes the link pointer to be unreferenced when the property is deleted. This fixes refcount leaks in qdev.c, xilinx_axidma.c, xilinx_axienet.c, s390-virtio-bus.c, virtio-pci.c, virtio-rng.c, and ui/console.c. Rationale for refcount behavior: * hw/core/qdev.c - bus children are explicitly unreferenced, don't interfere - parent_bus is essentially a read-only property that doesn't hold a refcount, don't unref - hotplug_handler is leaked, do unref * hw/dma/xilinx_axidma.c - rx stream "dma" links are set using set_link, therefore they need unref - tx streams are set using set_link, therefore they need unref * hw/net/xilinx_axienet.c - same reasoning as hw/dma/xilinx_axidma.c * hw/pcmcia/pxa2xx.c - pxa2xx bypasses set_link and therefore does not use refcounts * hw/s390x/s390-virtio-bus.c * hw/virtio/virtio-pci.c * hw/virtio/virtio-rng.c * ui/console.c - set_link is used and there is no explicit unref, do unref Cc: Peter Crosthwaite <peter.crosthwaite@petalogix.com> Cc: Alexander Graf <agraf@suse.de> Cc: Anthony Liguori <aliguori@amazon.com> Cc: "Michael S.

2013-12-24qom: Do not register interface "types" in the type table and fix namesPaolo Bonzini
There should be no need to look up nor enumerate the interface "types", whose "classes" are really just vtables. Just create the types and add them to the interface list of the parent type. Interfaces not registering their type anymore means that accessing superclass::interface by type name will fail when initializing subclass::interface. Thus, we need to pre-initialize the subclass's parent_type field before calling type_initialize. Apart from this, the interface "types" should never be used and thus it is harmless to leave them out of the hashtable. Further, the interface types had a bug with interfaces that are inherited from a superclass: The implementation type name was wrong (for example it was subclass::superclass::interface rather than just subclass::interface). This patch fixes this as well.
