2021-10-20virtio-net: vhost control virtqueue supportJason Wang
This patch implements the control virtqueue support for vhost. This requires virtio-net to figure out the datapath queue pairs and control virtqueue via is_datapath and pass the number of those two types of virtqueues to vhost_net_start()/vhost_net_stop().

2021-10-20vhost: record the last virtqueue index for the virtio deviceJason Wang
This patch introduces a new field in the vhost_dev structure to record the last virtqueue index for the virtio device.

2021-10-15qdev: Base object creation on QDict rather than QemuOptsKevin Wolf
QDicts are both what QMP natively uses and what the keyval parser produces. Going through QemuOpts isn't useful for either one, so switch the main device creation function to QDicts. By sharing more code with the -object/object-add code path, we can even reduce the code size a bit.

Instead of accessing the global QemuOptsList, which really belong to the command line parser and shouldn't be accessed from devices, store a pointer to the QemuOpts in a new VirtIONet field. This is not the final state, but just an intermediate step to get rid of QemuOpts in devices. It will later be replaced with an options QDict. Before this patch, two "primary" devices could be hidden for the same standby device, but only one of them would actually be enabled and the other one would be kept hidden forever, so this doesn't make sense.

In this way, we can reuse the same code for all virtio-vsock backends (i.e. vhost-vsock, vhost-user-vsock).

2021-10-05vhost-vsock: fix migration issue when seqpacket is supportedStefano Garzarella
Commit 1e08fd0a46 ("vhost-vsock: SOCK_SEQPACKET feature bit support") enabled the SEQPACKET feature bit. This commit is released with QEMU 6.1, so if we try to migrate a VM where the host kernel supports SEQPACKET but machine type version is less than 6.1, we get the following errors: Features 0x130000002 unsupported. Allowed features: 0x179000000 Failed to load virtio-vhost_vsock:virtio error while loading state for instance 0x0 of device '0000:00:05.0/virtio-vhost_vsock' load of migration failed: Operation not permitted Let's disable the feature bit for machine types < 6.1. We add a new OnOffAuto property for this, called `seqpacket`. When it is `auto` (default), QEMU behaves as before, trying to enable the feature, when it is `on` QEMU will fail if the backend (vhost-vsock kernel module) doesn't support it.

2021-09-04vhost-vdpa: Do not send empty IOTLB update batchesEugenio Pérez
With the introduction of the batch hinting, meaningless batches can be created with no IOTLB updates if the memory region was skipped by vhost_vdpa_listener_skipped_section. This is the case of host notifiers memory regions, device un/realize, and others. This causes the vdpa device to receive dma mapping settings with no changes, a possibly expensive operation for nothing. To avoid that, VHOST_IOTLB_BATCH_BEGIN hint is delayed until we have a meaningful (not skipped section) mapping or unmapping operation, and VHOST_IOTLB_BATCH_END is not written unless at least one of _UPDATE / _INVALIDATE has been issued. v3: * Use a bool instead of a counter avoiding potential number wrapping * Fix bad check on _commit * Move VHOST_BACKEND_F_IOTLB_BATCH check to vhost_vdpa_iotlb_batch_begin_once v2 (from RFC): * Rename misleading name * Abstract start batching function for listener_add/del Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Message-Id: <20210812140933.226288-1-eperezma@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> Reviewed-by: Michael S.

Before commit 49afbca3b00e8e517d54964229a794b51768deaf ("virtio-gpu: drop use_virgl_renderer"), use_virgl_renderer was preventing calling GL functions from non-GL context threads. The innocuously looking g->parent_obj.use_virgl_renderer = false; was set the first time virtio_gpu_gl_reset() was called, during pc_machine_reset() in the main thread. Further virtio_gpu_gl_reset() calls in IO threads, without associated GL context, were thus skipping GL calls and avoided warnings or crashes (see also https://gitlab.freedesktop.org/virgl/virglrenderer/-/issues/226).

2021-05-18vhost-user-blk: Check that num-queues is supported by backendKevin Wolf
Creating a device with a number of queues that isn't supported by the backend is pointless, the device won't work properly and the error messages are rather confusing. Just fail to create the device if num-queues is higher than what the backend supports. Since the relationship between num-queues and the number of virtqueues depends on the specific device, this is an additional value that needs to be initialised by the device. For convenience, allow leaving it 0 if the check should be skipped. This makes sense for vhost-user-net where separate vhost devices are used for the queues and custom initialisation code is needed to perform the check.

Now that we have separated the gl and non-gl code flows to two different devices there is little reason turn on and off virglrenderer usage at runtime. The gl code can simply use virglrenderer unconditionally. So drop use_virgl_renderer field and just do that.

2021-05-10virtio-gpu: move virgl realize + propertiesGerd Hoffmann
Move device init (realize) and properties. Drop the virgl property, the virtio-gpu-gl-device has virgl enabled no matter what. Just use virtio-gpu-device instead if you don't want enable virgl and opengl. This simplifies the logic and reduces the test matrix.

2021-05-10virtio-gpu: handle partial maps properlyGerd Hoffmann
dma_memory_map() may map only a part of the request. Happens if the request can't be mapped in one go, for example due to a iommu creating a linear dma mapping for scattered physical pages. Should that be the case virtio-gpu must call dma_memory_map() again with the remaining range instead of simply throwing an error. Note that this change implies the number of iov entries may differ from the number of mapping entries sent by the guest. Therefore the iov_len bookkeeping needs some updates too, we have to explicitly pass around the iov length now.

Report the configured granularity for discard operation to the guest. If this is not set use the block size. Since until now we have ignored the configured discard granularity and always reported the block size, let's add 'report-discard-granularity' property and disable it for older machine types to avoid migration issues.

2021-02-04display/ui: add a callback to indicate GL state is flushedMarc-André Lureau
Displaying rendered resources requires blocking qemu GPU to avoid extra framebuffer copies. For an external display, via Spice currently, there is a callback to block/unblock the rendering in the same thread. But with the vhost-user-gpu backend, the qemu process doesn't handle the rendering itself, and the blocking callback isn't effective. Instead, the backend must be notified when the display code is done. Fix this by adding a new GraphicHwOps callback to indicate the GL state is flushed, and we are done manipulating the shared GL resources. Call it from gtk and spice display.

2021-02-04virtio-gpu: avoid re-entering cmdq processingMarc-André Lureau
The next patch will notify the GL context got flush, which will resume the queue processing. However, if this happens within the caller context, it will end up with a stack overflow flush/update loop.
