2023-12-26vdpa: move memory listener to vhost_vdpa_sharedEugenio Pérez
Next patches will register the vhost_vdpa memory listener while the VM is migrating at the destination, so we can map the memory to the device before stopping the VM at the source. The main goal is to reduce the downtime. However, the destination QEMU is unaware of which vhost_vdpa device will register its memory_listener. If the source guest has CVQ enabled, it will be the CVQ device. Otherwise, it will be the first one. Move the memory listener to a common place rather than always in the first / last vhost_vdpa.

It is required to use error_report() instead of error_reportf_err(), if the prior function does not take local_err as the argument. As a result, the local_err is always NULL and segment fault may happen. vhost_scsi_start() -> vhost_scsi_set_endpoint(s) --> does not allocate local_err -> error_reportf_err() -> error_vprepend() -> g_string_append(newmsg, (*errp)->msg) --> (*errp) is NULL In addition, add ": " at the end of other error_reportf_err() logs.

2023-12-25hw/acpi: propagate vcpu hotplug after switch to modern interfaceAaron Young
If a vcpu with an apic-id that is not supported by the legacy interface (>255) is hot-plugged, the legacy code will dynamically switch to the modern interface. However, the hotplug event is not forwarded to the new interface resulting in the vcpu not being fully/properly added to the machine config. This BUG is evidenced by OVMF when it it attempts to count the vcpus and reports an inconsistent vcpu count reported by the fw_cfg interface and the modern hotpug interface. Fix is to propagate the hotplug event after making the switch from the legacy interface to the modern interface. Cc: "Michael S.

2023-12-25vhost-scsi: Add support for a worker thread per virtqueueMike Christie
This adds support for vhost-scsi to be able to create a worker thread per virtqueue. Right now for vhost-net we get a worker thread per tx/rx virtqueue pair which scales nicely as we add more virtqueues and CPUs, but for scsi we get the single worker thread that's shared by all virtqueues. When trying to send IO to more than 2 virtqueues the single thread becomes a bottlneck. This patch adds a new setting, worker_per_virtqueue, which can be set to: false: Existing behavior where we get the single worker thread. true: Create a worker per IO virtqueue.
