2013-02-01qdev: drop extra references at creation timePaolo Bonzini
qdev_free and qbus_free have to do unparent+unref, because nobody else drops the initial reference (the one included by object_initialize) before them. For device_init_func and do_device_add, this is trivially correct, since the DeviceState goes out of scope. For qdev_create, qdev_try_create and qbus_init, it is a bit more tricky. What we are doing here is just assuming that the caller knows what it's doing, and won't call qdev_free/qbus_free while the device is still there. This is a pretty reasonable assumption and (behind the scenes) is also what GObject/GTK does. GTK actually has a "floating reference" that goes away as soon as the caller does gtk_container_add or something like that, but in the end qbus_init and qdev_try_create are already adding the new object to its qdev parent! So in the end the two solutions are the same. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2013-02-01qdev: move unrealization of devices from finalize to unparentPaolo Bonzini
Similarly, a bus holds a reference back to the device, and this will prevent the device from going away as soon as this reference is counted properly. To avoid this, move the unrealization of devices to the unparent callback. This includes recursively unparenting all the buses and (after the previous patch) the devices on those buses, which ensures that the web of references completely disappears for all devices that reside (in the qdev tree) below the one being unplugged. After this patch, the qdev tree and the bus<->child relationship is defined as "A is above B, iff unplugging A will automatically unplug B".

Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (qdev: register all types natively through QEMU Object Model), TypeInfo as used in the common, non-iterative pattern is no longer amended with information and should therefore be const. Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.

2013-01-08qdev: Don't assume existence of parent bus on unparentingAndreas Färber
Commit 667d22d1ae59da46b4c1fbd094ca61145f19b8c3 (qdev: move bus removal to object_unparent) made the assumption that at unparenting time parent_bus is not NULL. This assumption is unjustified since object_unparent() may well be called directly after object_initialize(), without any qdev_set_parent_bus(). This did not cause any issues yet because qdev_[try_]create() does call qdev_set_parent_bus(), falling back to SysBus if unsupplied. While at it, ensure that this new function uses the device_ prefix and make the name more neutral in light of this semantic change.

2012-11-15qdev: Split up header so it can be used in cpu.hAnthony Liguori
Header file dependency is a frickin' nightmare right now. cpu.h tends to get included in our 'include everything' header files but qdev also needs to include those headers mainly for qdev-properties since it knows about CharDriverState and friends. We can solve this for now by splitting out qdev.h along the same lines that we previously split the C file.

Use g_strdup rather than strdup, because the sole caller (qdev_get_fw_dev_path_helper) assumes it gets non-NULL, and dereferences it. Besides, in that caller, the allocated buffer is already freed with g_free, so it's better to allocate with a matching g_strdup. In one case, (scsi-bus.c) it was trivial, so I replaced an snprintf+ g_strdup combination with an equivalent g_strdup_printf use.

2012-08-23qom: object_delete should unparent the object firstPaolo Bonzini
object_deinit is only called when the reference count goes to zero, and yet tries to do an object_unparent. Now, object_unparent either does nothing or it will decrease the reference count. Because we know the reference count is zero, the object_unparent call in object_deinit is useless. Instead, we need to disconnect the object from its parent just before we remove the last reference apart from the parent's. This happens in object_delete. Once we do this, all calls to object_unparent peppered through QEMU can go away. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-06-18qdev: Move bus properties to abstract superclassesPaolo Bonzini
In qdev, each bus in practice identified an abstract superclass, but this was mostly hidden. In QOM, instead, these abstract classes are explicit so we can move bus properties there. All bus property walks are removed, and all device property walks are changed to look along the class hierarchy instead. We would have duplicates if class A defines some properties and its subclass B does not define any, because class_b->props will be left equal to class_a->props. The solution here is to reintroduce the class_base_init TypeInfo callback, that was present in one of the early QOM versions but removed (on my request...) before committing. This breaks global bus properties, an obscure feature when used with the command-line which is actually useful and used when used by backwards-compatible machine types. So this patch also adjusts the global bus properties in hw/pc_piix.c to refer to the abstract class. Globals and other properties must be modified in the same patch to avoid complications related to initialization ordering.

2012-04-09qdev: qdev_unplug(): use error_set()Luiz Capitulino
It currently uses qerror_report(), but next commit will convert the drive_del command to the QAPI and this requires using error_set(). One particularity of qerror_report() is that it knows when it's running on monitor context or command-line context and prints the error message accordingly. error_set() doesn't do this, so we have to be careful not to drop error messages. qdev_unplug() has three kinds of usages: 1. It's called when hot adding a device fails, to undo anything that has been done before hitting the error 2. It's called by function monitor functions like device_del(), to unplug a device 3. It's used by xen_platform.c in a way that doesn't _seem_ to be in monitor context Only item 2 can print an error message to the user, this commit maintains that.
