I''ve picked up the ixgbe Xen VMDq stuff again, and I''m ready to start testing. However, I can''t the VMQ parts of Netchannel2 in the pvops kernel. I walked through all the git branches but still didn''t see anything. Has anybody ported this stuff to the pvops kernel, and if so, where can I get it? If nobody''s done this, then I''ll dive in and see if I can get it working. But I don''t want to waste the time if I don''t have to.

[Xen-devel] RE: VMQ support in pvops Netchannel2?
Mitch I am glad to hear you are working on this again. I have been working from Steven''s netchannel2 tree (git://xenbits.xensource.com/people/ssmith/nc2-2.6.27.git) which has the Xen VMQ bits. We were waiting for the ixgbe VMDq patches to be ported to pvops first. Now that you are working on that is time for us to port the Xen VMQ bits as well I am not sure what are Steven''s plan for that. Steven, will you be able to work on this? I would be glad to help if Steven is not available but I need help understanding which branch of the netchannel2 tree was the basis for the port to the pvops kernel.(Steven ? Jeremy?) Mitch, it would be great if could start working on the ixgbe side while we figure out how to proceed from the netchannel2 side.

RE: [Xen-devel] RE: VMQ support in pvops Netchannel2?
Pasi Sorry for the delay in responding. My email filter stored your message on my folder for xen-devel which I am not reading very often recently. The latest version of netchannel2 I worked on was on Steven''s nc2-2.6.27 kernel tree. That version does not have VMDq support since the Intel ixgbe driver in 2.6.27 does not have VMDq support. I am not sure what is Jeremy''s plan to port that code to pvops. But I think that is the first step. After that we can work on getting VMDq support with Mitch''s help. So I think Jeremy is probably the best person to give you an update on the plan to merge netechannel2 code into pvops.

There is no fundamental reason why the key features of nc2 could not be implemented as optional features of the existing front/back drivers, negotiated via xenstore.

I plan to start by adding negotiation of a new rx ring protocol to allow moving the grant copy to the frontend.
