Markus Armbruster	209e64d9ed	qapi: Refill doc comments to conform to current conventions For legibility, wrap text paragraphs so every line is at most 70 characters long. To check the generated documentation does not change, I compared the generated HTML before and after this commit with "wdiff -3". Finds no differences. Comparing with diff is not useful, as the refilled paragraphs are visible there.

Eric Auger	965bc08310	qdev: Add a granule_mode property Introduce a new enum type property allowing to set an IOMMU granule. Values are 4k, 8k, 16k, 64k and host. This latter indicates the vIOMMU granule will match the host page size. A subsequent patch will add such a property to the virtio-iommu device.

Stefan Hajnoczi	cf03a152c5	qdev: add IOThreadVirtQueueMappingList property type virtio-blk and virtio-scsi devices will need a way to specify the mapping between IOThreads and virtqueues. At the moment all virtqueues are assigned to a single IOThread or the main loop. This single thread can be a CPU bottleneck, so it is necessary to allow finer-grained assignment to spread the load. Introduce DEFINE_PROP_IOTHREAD_VQ_MAPPING_LIST() so devices can take a parameter that maps virtqueues to IOThreads. The command-line syntax for this new property is as follows: --device '{"driver":"foo","iothread-vq-mapping":[{"iothread":"iothread0","vqs":[0,1,2]},...]}' IOThreads are specified by name and virtqueues are specified by 0-based index. It will be common to simply assign virtqueues round-robin across a set of IOThreads. A convenient syntax that does not require specifying individual virtqueue indices is available: --device '{"driver":"foo","iothread-vq-mapping":[{"iothread":"iothread0"},{"iothread":"iothread1"},...]}' Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Message-ID: <20231220134755.814917-4-stefanha@redhat.com> Reviewed-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>	2 years ago

Laurent Vivier	1ee7bb5bef	qmp: add QMP command x-query-virtio-queue-element This new command shows the information of a VirtQueue element. [Note: Up until v10 of this patch series, virtio.json had many (15+) enums defined (e.g. decoded device features, statuses, etc.). In v10 most of these enums were removed and replaced with string literals. By doing this we get (1) simpler schema, (2) smaller generated code, and (3) less maintenance burden for when new things are added (e.g. devices, device features, etc.).] Signed-off-by: Laurent Vivier <lvivier@redhat.com> Signed-off-by: Jonah Palmer <jonah.palmer@oracle.com> Message-Id: <1660220684-24909-6-git-send-email-jonah.palmer@oracle.com> Reviewed-by: Michael S.

Laurent Vivier	f3034ad71f	qmp: decode feature & status bits in virtio-status Display feature names instead of bitmaps for host, guest, and backend for VirtIODevices. Display status names instead of bitmaps for VirtIODevices. Display feature names instead of bitmaps for backend, protocol, acked, and features (hdev->features) for vhost devices. Decode features according to device ID. Decode statuses according to configuration status bitmap (config_status_map). Decode vhost user protocol features according to vhost user protocol bitmap (vhost_user_protocol_map). Transport features are on the first line. Undecoded bits (if any) are stored in a separate field. [Jonah: Several changes made to this patch from prev. version (v14): - Moved all device features mappings to hw/virtio/virtio.c - Renamed device features mappings (less generic) - Generalized @FEATURE_ENTRY macro for all device mappings - Virtio device feature map definitions include descriptions of feature bits - Moved @VHOST_USER_F_PROTOCOL_FEATURES feature bit from transport feature map to vhost-user-supported device feature mappings (blk, fs, i2c, rng, net, gpu, input, scsi, vsock) - New feature bit added for virtio-vsock: @VIRTIO_VSOCK_F_SEQPACKET - New feature bit added for virtio-iommu: @VIRTIO_IOMMU_F_BYPASS_CONFIG - New feature bit added for virtio-mem: @VIRTIO_MEM_F_UNPLUGGED_INACCESSIBLE - New virtio transport feature bit added: @VIRTIO_F_IN_ORDER - Added device feature map definition for virtio-rng ] Signed-off-by: Laurent Vivier <lvivier@redhat.com> Signed-off-by: Jonah Palmer <jonah.palmer@oracle.com> Message-Id: <1660220684-24909-4-git-send-email-jonah.palmer@oracle.com> Reviewed-by: Michael S.

Laurent Vivier	a5ebce3857	qmp: add QMP command x-query-virtio This new command lists all the instances of VirtIODevices with their canonical QOM path and name. [Jonah: @virtio_list duplicates information that already exists in the QOM composition tree. However, extracting necessary information from this tree seems to be a bit convoluted. Instead, we still create our own list of realized virtio devices but use @qmp_qom_get with the device's canonical QOM path to confirm that the device exists and is realized. If the device exists but is actually not realized, then we remove it from our list (for synchronicity to the QOM composition tree). Also, the QMP command @x-query-virtio is redundant as @qom-list and @qom-get are sufficient to search '/machine/' for realized virtio devices. However, @x-query-virtio is much more convenient in listing realized virtio devices.] Signed-off-by: Laurent Vivier <lvivier@redhat.com> Signed-off-by: Jonah Palmer <jonah.palmer@oracle.com> Message-Id: <1660220684-24909-2-git-send-email-jonah.palmer@oracle.com> Reviewed-by: Michael S.
