* vhost-user-vsock-pci: force virtio version 1Stefano Garzarella2020-09-291-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 9b3a35ec82 ("virtio: verify that legacy support is not accidentally on") added a safety check that requires to set 'disable-legacy=on' on vhost-user-vsock-pci device: $ ./qemu-system-x86_64 ... \ -chardev socket,id=char0,reconnect=0,path=/tmp/vhost4.socket \ -device vhost-user-vsock-pci,chardev=char0 qemu-system-x86_64: -device vhost-user-vsock-pci,chardev=char0: device is modern-only, use disable-legacy=on virtio-vsock was introduced after the release of VIRTIO 1.0 specifications, so it should be 'modern-only'. This patch forces virtio version 1 and removes the 'transitional_name' property, as done for vhost-vsock-pci, removing the need to specify 'disable-legacy=on' on vhost-user-vsock-pci device.

* Move QOM typedefs and add missing includesEduardo Habkost2020-09-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some typedefs and macros are defined after the type check macros. This makes it difficult to automatically replace their definitions with OBJECT_DECLARE_TYPE. Patch generated using: $ ./scripts/codeconverter/converter.py -i \ --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]') which will split "typdef struct { ... } TypedefName" declarations. Followed by: $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \ $(git grep -l '' -- '*.[ch]') which will: - move the typedefs and #defines above the type check macros - add missing #include "qom/object.h" lines if necessary Reviewed-by: Daniel P.

* qdev: Convert uses of qdev_set_parent_bus() with CoccinelleMarkus Armbruster2020-06-151-2/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In addition to the qdev_create() patterns converted so far, we have a qdev_set_parent_bus() pattern. Mostly when we embed a device in a parent device rather than allocating it on the heap. This pattern also puts devices in the dangerous "no QOM parent, but plugged into bus" state I explained in recent commit "qdev: New qdev_new(), qdev_realize(), etc." Apply same solution: convert to qdev_realize(). Coccinelle script: @@ expression dev, bus, errp; symbol true; @@ - qdev_set_parent_bus(DEVICE(dev), bus); ... - object_property_set_bool(OBJECT(dev), true, "realized", errp); + qdev_realize(DEVICE(dev), bus, errp); @ depends on !(file in "qdev-monitor.c") && !(file in "hw/core/qdev.c")@ expression dev, bus, errp; symbol true; @@ - qdev_set_parent_bus(dev, bus); ... - object_property_set_bool(OBJECT(dev), true, "realized", errp); + qdev_realize(dev, bus, errp); @@ expression dev, bus; symbol true; @@ - qdev_set_parent_bus(DEVICE(dev), bus); ... - qdev_init_nofail(DEVICE(dev)); + qdev_realize(DEVICE(dev), bus, &error_fatal); Unconverted uses of qdev_set_parent_bus() remain. They'll be converted later in this series.
