Hi Andrew,
Happy to know that solarflare is interested in this enablement work.

The meeting will be over skype at,

Monday, March 5, 2018 11:30 AM-12:30 PM (GMT, Dublin)


Looks like the meeting time got removed when the skype invite is formatted to 
‘plain text’.

Subject: Re: [ovs-dev] Hardware acceleration enablement in OVS-DPDK

Hello Sugesh,

we (Solarflare) are also interested in the topic as well. I've added Rob and 
Neil in CC.
We would like to participate as well, however, I do not see date and time of 
the call.

Thanks,
Andrew.

Hello All,



I am setting up next call in this series to discuss further on approaches to 
enable full hardware acceleration in OVS-DPDK.



Agenda for this meeting is to discuss further on two proposals (one from Intel 
and another from Napatech) for enabling full hardware acceleration in OVS-DPDK.



The Previous meeting minutes can be found at following google doc



https://docs.google.com/document/d/1KeQB5NIUph721uuk1f1wMy4QXwSWxlzDaumd_bWX6YI/edit?usp=sharing



I would encourage everyone to have look at the following two patch series 
before the call, so that we can have a productive discussion.





The Napatech hardware acceleration approach in OVS-DPDK can be found below,





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.



Thanks,

Finn









The intel hardware acceleration proposal can be found at









Hello All,



As discussed in the last meeting, I have created a OVS 2.7 fork with our 
hardware acceleration implementation as below.





https://github.com/sugchand/ovs.git (branch - 
dpdk-hw-accel-intel<https://github.com/sugchand/ovs/tree/dpdk-hw-accel-intel><https://github.com/sugchand/ovs/tree/dpdk-hw-accel-intel>)



Few points on the implementation.

1)      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!





Regards

_Sugesh
