Hi All, As agreed in last meeting, I have created an OVS branch of our OVS fork (from late January - v2.9), and added the Partial hw offload proposal, followed by our full offload extension - 3 additional commits. It should compile against DPDK 17.11, and for that to be possible an existing RTE_FLOW_ACTION_TYPE_VF is (mis-)used to send port-id to PMD. Furthermore, tcp_flags update from NIC is commented out due to lack of that field in the RTE FLOW query structure. Please see this as a PoC. It is not yet ready for an actual proposal, though it is fully functioning in our lab.
https://github.com/napatech/ovs/tree/hw-full-offload-v1 Further notes: As mentioned at the last meeting, this proposal is based on vPorts on NIC (being VF, virtio or other vPort), completely handled outside OVS. The vPorts are then connected and configured in OVS as "normal" type=dpdk ports. I know this is not in-line with Intels proposal, however, we think it might be a good idea. It makes it simpler in OVS, since we only need either capabilities, or trial & error to do transparent full hw-offload. Anyway, this is our current proposal for the next discussion meeting.

This implementation is just for reference to show the proposal. 2. The code is still 2.7 based. We will merge to latest branch once we have finalized on the approach. 3. Some of the hardware acceleration functionalities still missing in this implementation, such as flow offload thread , flow stat and tcp-flag handling. We are working on it to add those support. 4. This implementation uses some of hardware specific APIs that are not yet available in the DPDK main tree. So the code may not build properly. Please review the implementation (in the last 12 commits), Will setup a follow up call to discuss further on this. Thank you!

Where: Skype Meeting Hi All, As discussed in the last hardware acceleration meeting, I am setting up the follow up call to discuss about submitting a RFC patch series on OVS-DPDK full hardware acceleration solution. This time I am scheduling the call at PRC time zone friendly. Agenda for the Call 1. DPDK changes that Intel is working on to support Full offload.(RTE_FLOW changes, port-rep) 2. Proposed OVS changes for the full acceleration. How it can leverage the proposed DPDK APIs. Also look at how these changes will work with hardware from different vendors 3. How the proposal is going to interfere the existing partial offload solution. MOM of last call can be found at following link. Minutes will be captures in the same doc. https://docs.google.com/document/d/1KeQB5NIUph721uuk1f1wMy4QXwSWxlzDaumd_bWX6YI/edit?usp=sharing ......................................................................................................................................... --> Join Skype Meeting<https://meet.intel.com/sugesh.chandran/QLTNR3L5> Trouble Joining?
