| 2025-02-21 | vhost-user-snd: correct the calculation of config_size | Matias Ezequiel Vara Larsen | 1 | -1/+17 | |
| Use virtio_get_config_size() rather than sizeof(struct virtio_snd_config) for the config_size in the vhost-user-snd frontend. The frontend shall rely on device features for the size of the device configuration space. The presence of `controls` in the config space depends on VIRTIO_SND_F_CTLS according to the specification (v1.3): ` 5.14.4 Device Configuration Layout ... controls (driver-read-only) indicates a total number of all available control elements if VIRTIO_SND_F_CTLS has been negotiated. ` This fixes an issue introduced by commit ab0c7fb2 ("linux-headers: update to current kvm/next") in which the optional field `controls` is added to the virtio_snd_config structure. This breaks vhost-user-device backends that do not implement the `controls` field.

| 2024-12-19 | include/hw/qdev-properties: Remove DEFINE_PROP_END_OF_LIST | Richard Henderson | 1 | -1/+0 | |
| Now that all of the Property arrays are counted, we can remove the terminator object from each array. Update the assertions in device_class_set_props to match. With struct Property being 88 bytes, this was a rather large form of terminator. Saves 30k from qemu-system-aarch64.
