Virtio PMD implementation will follow in a next series. The series applies on top of previous reworks I posted during this cycle that merges mergeable and non-mergeable receive paths, and refactors transmit path to re-use vector buffers. I haven't run performance tests for now as the Virtio PMD side isn't ready. The series has been tested with Tiwei's series implementing packed ring support to Kernel's virtio-net driver, and with Wei series implementing the Qemu side. To test it, I have used testpmd on host side with a vhost vdev and a tap vdev forwarding to each other. Transferts of big random files have been done in both ways with integrity verified. Tests have been run with Rx mrg ON/OFF and events suppression ON/OFF. Tests have also been run with legacy split ring layout to ensure no regression have been introduced. Changes since v8: ================= - Fix indents (Tiwei) - Rename struct vring_desc_packed to vring_packed_desc (Tiwei) Changes since v7: ================= - Align structs and defines naming with Kernel header (Tiwei) - Fix event based notifications (Tiwei) - Fix Clang build issues caused by unused symbols (Tiwei) Changes since v6: ================= - Various style cleanups (Tiwei, Jason) - Simplify event based notification (Jason) - Build support with future kernels (Tiwei) - Prevent buffer vectors overflow in map_one_desc (Tiwei) Changes since v5: ================= - Remove duplicated VHOST_USER_F_PROTOCOL_FEATURES definition (Tiwei) - Fix vq_is_ready (Maxime) - Fix local used index overflow in flush_shadow_used_ring_packed (Tiwei) - Make desc_is_avail() a bool (Tiwei) - Improve desc_is_avail() logic (Tiwei) - Remove split rings addr NULL assignment in the right patch (Tiwei) - Make buffer id a uint16_t (Tiwei) Jens Freimann (2): vhost: add virtio packed virtqueue defines vhost: add helpers for packed virtqueues Maxime Coquelin (12): vhost: clear shadow used table index at flush time vhost: make indirect desc table copy desc type agnostic vhost: clear batch copy index at copy time vhost: extract split ring handling from Rx and Tx functions vhost: append shadow used ring function names with split vhost: add shadow used ring support for packed rings vhost: create descriptor mapping function vhost: add vector filling support for packed ring vhost: add Rx support for packed ring vhost: add Tx support for packed ring vhost: add notification for packed ring vhost: advertize packed ring layout support Yuanhan Liu (1): vhost: vring address setup for packed queues lib/librte_vhost/vhost.c | 115 ++++++- lib/librte_vhost/vhost.h | 130 ++++++- lib/librte_vhost/vhost_user.c | 127 +++++-- lib/librte_vhost/virtio_net.c | 776 +++++++++++++++++++++++++++++++++--------- 4 files changed, 939 insertions(+), 209 deletions(-) Acked-by: Tiwei Bie
