* virtio: move common virtio properties to bus class deviceMing Lei2014-07-061-0/+2
| | | | | | | | | | | | | | | | The two common virtio features can be defined per bus, so move all into bus class device to make code more clean. As discussed with cornelia, s390-virtio-blk doesn't support the two features at all, so keep s390-virtio as it.

* virtio-blk: replace x-iothread with iothread link propertyStefan Hajnoczi2014-07-011-0/+2
| | | | | | | | | | | | | | | | Up until now -device virtio-blk-pci,x-iothread=<id> was used to assign an IOThread. This was a temporary solution while we cleaned up QOM link properties. This patch switches over to a QOM link property since it is now possible to restrict the setter to unrealized instances and automatically unref the IOThread when the virtio-blk-pci device is freed. Since the "iothread" property is a QOM property and not a qdev property, we must alias it explicitly for virtio-blk-pci, as well as CCW and s390-virtio.

* virtio: fix virtio-blk child refcount in transportsStefan Hajnoczi2014-07-011-0/+1
| | | | | | | | | | | | | | | object_initialize() leaves the object with a refcount of 1. object_property_add_child() adds its own reference which is dropped again when the property is deleted. The upshot of this is that we always have a refcount >= 1. Upon hot unplug the virtio-blk child is not finalized! Drop our reference after the child property has been added to the parent.

* virtio-blk: use aliases instead of duplicate qdev propertiesStefan Hajnoczi2014-07-011-8/+1Star
| | | | | | | | | | | | | | | | virtio-blk-pci, virtio-blk-s390, and virtio-blk-ccw all duplicate the qdev properties of their VirtIOBlock child. This approach does not work well with string or pointer properties since we must be careful about leaking or double-freeing them. Use the QOM alias property to forward property accesses to the VirtIOBlock child. This way no duplication is necessary. Remember to stop calling virtio_blk_set_conf() so that we don't clobber the values already set on the VirtIOBlock instance.

* qom: Add check() argument to object_property_add_link()Stefan Hajnoczi2014-03-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* qom: Make QOM link property unref optionalStefan Hajnoczi2014-03-191-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* sysbus: Set cannot_instantiate_with_device_add_yetMarkus Armbruster2013-12-231-2/+0Star
| | | | | | | | | | | | | | | | | | device_add plugs devices into suitable bus. For "real" buses, that actually connects the device. For sysbus, the connections need to be made separately, and device_add can't do that. The device would be left unconnected, and could not possibly work. Quite a few, but not all sysbus devices already set cannot_instantiate_with_device_add_yet in their class init function. Set it in their abstract base's class init function sysbus_device_class_init(), and remove the now redundant assignments from device class init functions.

* qdev: Replace no_user by cannot_instantiate_with_device_add_yetMarkus Armbruster2013-12-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In an ideal world, machines can be built by wiring devices together with configuration, not code. Unfortunately, that's not the world we live in right now. We still have quite a few devices that need to be wired up by code. If you try to device_add such a device, it'll fail in sometimes mysterious ways. If you're lucky, you get an unmysterious immediate crash. To protect users from such badness, DeviceClass member no_user used to make device models unavailable with -device / device_add, but that regressed in commit 18b6dad. The device model is still omitted from help, but is available anyway. Attempts to fix the regression have been rejected with the argument that the purpose of no_user isn't clear, and it's prone to misuse. This commit clarifies no_user's purpose. Anthony suggested to rename it cannot_instantiate_with_device_add_yet_due_to_internal_bugs, which I shorten somewhat to keep checkpatch happy. While there, make it bool. Every use of cannot_instantiate_with_device_add_yet gets a FIXME comment asking for rationale. The next few commits will clean them all up, either by providing a rationale, or by getting rid of the use. With that done, the regression fix is hopefully acceptable.

* Allow virtio-net features for legacy s390 virtio busChristian Borntraeger2013-03-081-0/+1
| | | | | | | | | Enable all virtio-net features for the legacy s390 virtio bus. This also fixes kernel BUG at /usr/src/packages/BUILD/kernel-default-3.0.58/linux-3.0/drivers/s390/kvm/kvm_virtio.c:121!

* target-s390x: Clean up cpu_inject_*() signaturesAndreas Färber2013-02-011-3/+1Star
| | | | | | | | | | | | | | | | | | Despite cautioning that S390CPU is needed for upcoming CPUState refactorings, commit 5d69c547d947798cba92d836d06f6e017ba2b19d (s390: I/O interrupt and machine check injection.) added functions cpu_inject_io() and cpu_inject_crw_mchk() with CPUS390XState argument, claiming consistency with cpu_inject_ext(). This complicates making cpu_interrupt() take a CPUState even more and it required to pass &cpu->env from some S390CPU-aware call sites already, creating inconsistency elsewhere. Address that. This also eliminates the need for CPUS390XState in s390_virtio_irq().
