Consequently, there will be multiple pending buffers in the shadow VirtQueue, making it a must for every control command to have its own buffer. To achieve this, this patch refactor vhost_vdpa_net_cvq_add() to accept `struct iovec`, which eliminates the coupling of control commands to `s->cvq_cmd_out_buffer` and `s->status`, allowing them to use their own buffer.

Considering that QEMU always forwards the CVQ command serialized outside of vhost_vdpa_net_load(), it is more elegant to send the CVQ commands directly without invoking vhost_vdpa_net_load_*() helpers.

Addtionally, it includes a helper function vhost_vdpa_net_load_cursor_reset() for resetting these cursors. Furthermore, this patch refactors vhost_vdpa_net_load_cmd() so that vhost_vdpa_net_load_cmd() prepares buffers for the device using the cursors arguments, instead of directly accesses `s->cvq_cmd_out_buffer` and `s->status` fields. By making these change, next patches in this series can refactor vhost_vdpa_net_load_cmd() directly to iterate through the control commands shadow buffers, allowing QEMU to send CVQ state load commands in parallel at device startup.

To achieve this, this patch exposes vhost_svq_available_slots(), allowing QEMU to know whether the SVQ is full.

This allows different CVQ state load commands to use their own unique buffers. * Delay the polling and checking of buffers until either the SVQ is full or control commands shadow buffers are full.

We'll want to allow some of those callers to wait for a reply. Therefore, rebase "vhost_set_vring" from just "vhost_user_write" to "vhost_user_write_sync", exposing the "wait_for_reply" parameter. This is purely refactoring -- there is no observable change. That's because: - all three callers pass in "false" for "wait_for_reply", which disables all logic in "vhost_user_write_sync" except the call to "vhost_user_write"; - the fds=3DNULL and fd_num=3D0 arguments of the original "vhost_user_write" call inside "vhost_set_vring" are hard-coded within "vhost_user_write_sync".

These together mean that the following sub-sequence of steps is valid for a virtio-1.0 guest driver: (1.1) set "queue_enable" for the needed queues as the final part of device initialization step (7), (1.2) set DRIVER_OK in step (8), (1.3) immediately start sending virtio requests to the device. (2) When vhost-user is enabled, and the VHOST_USER_F_PROTOCOL_FEATURES special virtio feature is negotiated, then virtio rings start in disabled state, according to . In this case, explicit VHOST_USER_SET_VRING_ENABLE messages are needed for enabling vrings. Therefore setting "queue_enable" from the guest (1.1) -- which is technically "buffered" on the QEMU side until the guest sets DRIVER_OK (1.2) -- is a *control plane* operation, which -- after (1.2) -- travels from the guest through QEMU to the vhost-user backend, using a unix domain socket. Whereas sending a virtio request (1.3) is a *data plane* operation, which evades QEMU -- it travels from guest to the vhost-user backend via eventfd. This means that operations ((1.1) + (1.2)) and (1.3) travel through different channels, and their relative order can be reversed, as perceived by the vhost-user backend. That's exactly what happens when OVMF's virtiofs driver (VirtioFsDxe) runs against the Rust-language virtiofsd version 1.7.2. (Which uses version 0.10.1 of the vhost-user-backend crate, and version 0.8.1 of the vhost crate.) Namely, when VirtioFsDxe binds a virtiofs device, it goes through the device initialization steps (i.e., control plane operations), and immediately sends a FUSE_INIT request too (i.e., performs a data plane operation). In the Rust-language virtiofsd, this creates a race between two components that run *concurrently*, i.e., in different threads or processes: - Control plane, handling vhost-user protocol messages: The "VhostUserSlaveReqHandlerMut::set_vring_enable" method [crates/vhost-user-backend/src/handler.rs] handles VHOST_USER_SET_VRING_ENABLE messages, and updates each vring's "enabled" flag according to the message processed. - Data plane, handling virtio / FUSE requests: The "VringEpollHandler::handle_event" method [crates/vhost-user-backend/src/event_loop.rs] handles the incoming virtio / FUSE request, consuming the virtio kick at the same time. If the vring's "enabled" flag is set, the virtio / FUSE request is processed genuinely. If the vring's "enabled" flag is clear, then the virtio / FUSE request is discarded. Note that OVMF enables the queue *first*, and sends FUSE_INIT *second*. However, if the data plane processor in virtiofsd wins the race, then it sees the FUSE_INIT *before* the control plane processor took notice of VHOST_USER_SET_VRING_ENABLE and green-lit the queue for the data plane processor. Therefore the latter drops FUSE_INIT on the floor, and goes back to waiting for further virtio / FUSE requests with epoll_wait. Meanwhile OVMF is stuck waiting for the FUSET_INIT response -- a deadlock. The deadlock is not deterministic. OVMF hangs infrequently during first boot. However, OVMF hangs almost certainly during reboots from the UEFI shell. The race can be "reliably masked" by inserting a very small delay -- a single debug message -- at the top of "VringEpollHandler::handle_event", i.e., just before the data plane processor checks the "enabled" field of the vring. That delay suffices for the control plane processor to act upon VHOST_USER_SET_VRING_ENABLE. We can deterministically prevent the race in QEMU, by blocking OVMF inside step (1.2) -- i.e., in the write to the device status register that "unleashes" queue enablement -- until VHOST_USER_SET_VRING_ENABLE actually *completes*. That way OVMF's VCPU cannot advance to the FUSE_INIT submission before virtiofsd's control plane processor takes notice of the queue being enabled. Wait for VHOST_USER_SET_VRING_ENABLE completion by: - setting the NEED_REPLY flag on VHOST_USER_SET_VRING_ENABLE, and waiting for the reply, if the VHOST_USER_PROTOCOL_F_REPLY_ACK vhost-user feature has been negotiated, or - performing a separate VHOST_USER_GET_FEATURES *exchange*, which requires a backend response regardless of VHOST_USER_PROTOCOL_F_REPLY_ACK.

Used to be sent to request disabling all rings, but some back-ends interpreted it to also discard connection state (this interpretation would lead to bugs). It is recommended that back-ends either ignore this message, or use it to disable all rings. The only caller of vhost_user_reset_device() is vhost_user_scsi_reset(). It checks that F_RESET_DEVICE was negotiated before calling it: static void vhost_user_scsi_reset(VirtIODevice *vdev) { VHostSCSICommon *vsc =3D VHOST_SCSI_COMMON(vdev); struct vhost_dev *dev =3D &vsc->dev; /* * Historically, reset was not implemented so only reset devices * that are expecting it. */ if (!virtio_has_feature(dev->protocol_features, VHOST_USER_PROTOCOL_F_RESET_DEVICE)) { return; } if (dev->vhost_ops->vhost_reset_device) { dev->vhost_ops->vhost_reset_device(dev); } } Therefore VHOST_USER_RESET_OWNER is actually never sent by vhost_user_reset_device(). Remove the dead code. This effectively moves the vhost-user protocol specific code from vhost-user-scsi.c into vhost-user.c where it belongs.

The device is left non-operational since SET_OWNER is only called once during startup in vhost_dev_init(). vhost_kernel_reset_device() is never called so this latent bug never appears. Get rid of vhost_kernel_reset_device() for now. If someone needs it in the future they'll need to implement it correctly.

The other vhost devices don't notify the vhost device upon reset. Stateful vhost devices may need to handle device reset in order to free resources or prevent stale device state from interfering after reset. Call ->vhost_device_reset() from virtio_reset() so that that vhost devices are notified of device reset. This patch affects behavior as follows: - vhost-kernel: No change in behavior since ->vhost_reset_device() is not implemented. - vhost-user: back-ends that negotiate VHOST_USER_PROTOCOL_F_RESET_DEVICE now receive a VHOST_USER_DEVICE_RESET message upon device reset. Otherwise there is no change in behavior. DPDK, SPDK, libvhost-user, and the vhost-user-backend crate do not negotiate VHOST_USER_PROTOCOL_F_RESET_DEVICE automatically. - vhost-vdpa: an extra SET_STATUS 0 call is made during device reset.

Back then rev3 of the FADT was us= ed which required the reset register to be populated and there was common code. In commit 3a3fcc75f92a ("pc: acpi: force FADT rev1 for 440fx based machine types") the FADT was downgraded to rev1 for PIIX where the reset register i= sn't available. Thus, there is no need for the assertion any longer, so remove i= t.

Instead, it relies on the board to do so. This means that the board needs to wire the ISA IRQs to the PIIX3 device model. As long as the board assigns the ISA IRQs after PIIX3's realize(), internal devices can't be wir= ed in pci_piix3_realize() since the qemu_irqs are still NULL. Fix that by assigni= ng the ISA interrupts before realize(). This will allow for embedding child de= vices into the host device as already done for PIIX4.

Fix that by assigning the ISA interrupts before realize(). This change is necessary for PIIX consolidation because PIIX4 wires the RTC interrupts in its realize() method, so PIIX3 needs to do so as well. Since = the PC and Q35 boards share RTC code, and since PIIX3 needs the change, ICH9 ne= eds to be adapted as well.

If the backend finds that it receives the second get_inflight_fd, it will release = the previous shared memory, which breaks inflight working logic.

The reason is: When the vhost-user fails at get_features, the vhost_dev_cleanup will be ca= lled immediately. vhost_dev_cleanup calls 'memset(hdev, 0, sizeof(struct vhost_dev))'. The reconnect path is: vhost_user_blk_event vhost_user_async_close(.. vhost_user_blk_disconnect ..) qemu_chr_fe_set_handlers <----- clear the notifier callback schedule vhost_user_async_close_bh The vhost->vdev is null, so the vhost_user_blk_disconnect will not be called, then the event fd callback will not be reinstalled. All vhost-user devices have this issue, including vhost-user-blk/scsi. With this patch, if the vdev->vdev is null, the fd callback will still be reinstalled.

However, it seems it was never added to qemu's code, but it is well possible that it is already used by different front-ends outside of qemu (i.e., Xen). VHOST_USER_PROTOCOL_F_SHARED_OBJECT in contrast was added to qemu's code in 16094766627, but never defined in the vhost-user specification. As a consequence, both bits were defined to be 17, which cannot work. Regardless of whether actual code or the specification should take precedence, F_XEN_MMAP is already part of a qemu release, while F_SHARED_OBJECT is not. Therefore, bump the latter to take number 18 instead of 17, and add this to the specification. Take the opportunity to add at least a little note on the VhostUserShared structure to the specification. This structure is referenced by the new commands introduced in 16094766627, but was not defined.

The VTD_FR_IR_xxx values are supposed to be used to actually raise faults through the fault reporting mechanism, so do that instead for the case where the IRQ is actually being injected. There is more work to be done here, as pretranslations for the KVM IRQ routing table can't fault; an untranslatable IRQ should be handled in userspace and the fault raised only when the IRQ actually happens (if indeed the IRTE is still not valid at that time). But we can work on that later; we can at least raise faults for the direct case.
