[dpdk-dev] Hyper-v support

[dpdk-dev] Hyper-v support

[Jaime Zelaya]

Hi,
I followed the hyper-v support thread on this board, but
I haven't seen any release notes for hyper-v yet.
Questions:
Was hyper-v support released as planned ?
If so, in what release ?
If not, what release of DPDK will support it ?
and last,
What kernel version is required ?

Thank you so much for your attention

The code from Brocade was on older release, and depended on a slightly different model
for UIO interaction. Resolving this has taken longer than expected. Also the changes from

The changes to PCI for v16.11 overlapped vmbus related changes.

I don't understand what you mean.

Please, could you send a patch for the web roadmap?

Yes, the plan is the same. Since DPDK is moving target, getting merges done has been
a real pain.  The Hyper-V UIO generic driver has just gone into upstream next tree.
Therefore the driver will depend on 4.10 kernel initially.

Stephen did a presentation at the last DPDK userspace summit:

Stephen, please, could you confirm the expected release for Hyper-V support?
A patch for the roadmap page would be great:

[dpdk-dev] Hyper-v support

[Varun]

Hi,

I would like to know if the latest DPDK (16.11) supports hyper-v?

I couldn't find any conclusive evidence online or in dpdk roadmap. Is it
likely that we see it in 17.05?
