When we wait for a descriptor to be marked as used we need to consider that the ring might have wrapped and use the previous wrap counter. Patch 2 reverts the patch to error out when cq is used with packed vq and add support for packed virtqueues in control virtqueue code. v3->v4: * it's enough to add to add packed vq feature bit to unsupported_features if packed_vq=0, no need to explicitly add it to device_features (Tiwei) v2->v3: * squash revert patch into patch 2 * add new patch 1 to fix a bug in driver code * fix wrap handling code in virtio_user_handle_cq_packed * in v2 I was using wrap counters and indexes from shared virtqueue, fixed this and added wrap counters and used index to virtio_user code * tested wrap around of ring v1->v2: * split into two patches * handle ring wrap correctly * add to unsupported_features when packed_vq is 0 Jens Freimann (2): net/virtio: check head desc with correct wrap counter net/virtio-user: ctrl vq support for packed drivers/net/virtio/virtio_ethdev.c | 11 +- .../net/virtio/virtio_user/virtio_user_dev.c | 102 ++++++++++++++++-- .../net/virtio/virtio_user/virtio_user_dev.h | 15 ++- drivers/net/virtio/virtio_user_ethdev.c | 56 +++++++++- drivers/net/virtio/virtqueue.h | 10 +- 5 files changed, 171 insertions(+), 23 deletions(-) -- 2.17.2
