Tested in virtio-pci bus and virtio-mmio bus Change in v2: Add support for virtio-mmio bus active the notifier while the backend support configure interrupt misc fixes from v1 Change in v3 fix the coding style problems Change in v4 misc fixes from v3 merge the set_config_notifier to set_guest_notifier when vdpa start, check the feature by VIRTIO_NET_F_STATUS Change in v5 misc fixes from v4 split the code to introduce configure interrupt type and the callback function will init the configure interrupt in all virtio-pci and virtio-mmio bus, but will only active while using vhost-vdpa driver Change in v6 misc fixes from v5 decouple vq from interrupt setting and misc process fix the bug in virtio_net_handle_rx Change in v7 misc fixes from v6 decouple vq from interrupt setting and misc process decouple vq from vector use/release process decouple vq from set notifier fd handler process move config_notifier and masked_config_notifier to VirtIODevice fix the bug in virtio_net_handle_rx, add more information add VIRTIO_CONFIG_IRQ_IDX as the queue number for configure interrupt Change in v8 misc fixes from v7 decouple vq from interrupt setting and misc process decouple vq from vector use/release process decouple vq from set notifier fd handler process move the vhost configure interrupt to vhost_net Change in v9 misc fixes from v8 address the comments from v8 Change in v10 fix the hang issue in qtest address the comments from v9 Change in v11 fix the crash in aarch64 plateform. fix the crash upstream reported Change in v12 fix the typo and the comments changes in v13 re-send the patches by git-publish changes in v14 rebased the code based on upstream changes in v15 rebased the code based on upstream changes in v16 resend the patch, seems there not send successfully changes in v18 fix the crash in qtest Because hw/virtio/vhost-user-gpio.c is a new device,So I missed to add the VIRTIO_CONFIG_IRQ_IDX check in notifier_mask Cindy Lu (10): virtio: introduce macro VIRTIO_CONFIG_IRQ_IDX virtio-pci: decouple notifier from interrupt process virtio-pci: decouple the single vector from the interrupt process vhost: introduce new VhostOps vhost_set_config_call vhost-vdpa: add support for config interrupt virtio: add support for configure interrupt vhost: add support for configure interrupt virtio-net: add support for configure interrupt virtio-mmio: add support for configure interrupt virtio-pci: add support for configure interrupt hw/display/vhost-user-gpu.c | 18 ++ hw/net/vhost_net.c | 9 + hw/net/virtio-net.c | 22 ++- hw/virtio/trace-events | 1 + hw/virtio/vhost-user-fs.c | 18 ++ hw/virtio/vhost-user-gpio.c | 10 ++ hw/virtio/vhost-vdpa.c | 8 + hw/virtio/vhost-vsock-common.c | 18 ++ hw/virtio/vhost.c | 78 +++++++- hw/virtio/virtio-crypto.c | 18 ++ hw/virtio/virtio-mmio.c | 27 +++ hw/virtio/virtio-pci.c | 283 +++++++++++++++++++++--------- hw/virtio/virtio.c | 29 +++ include/hw/virtio/vhost-backend.h | 3 + include/hw/virtio/vhost.h | 4 + include/hw/virtio/virtio-pci.h | 4 +- include/hw/virtio/virtio.h | 7 + include/net/vhost_net.h | 2 + 18 files changed, 472 insertions(+), 87 deletions(-)
