SoftRoCE V1

SoftRoCE V1

[Wenda Ni]

Hi experts,

We have several Mellanox RoCE V1 NIC cards, and would like to try
communicating with SoftRoCE V1.

We are using branch rxe-3.0 from https://github.com/SoftRoCE/rxe-dev
according to the Soft-RoCE README Rev 1.0 issued from Mellanox last
year.


Testing using pingpong examples from libibverbs (hardware RoCE <->
SoftRoCE) already shows a bug in Ethernet CRC generation. We expect
further bugs along the way.

So we would like to know for SoftRoCE V1, are we using the latest
branch? Also, is it still tied to SLES11 SP3 OS?

There are very few documentations we can find, so we hope this is the
right place to ask such questions.

Cheers,

Wenda Ni, Ph.D.

Kamal can correct me if I'm wrong, but I think the updated branch is rxe_submission-v2.
However it doesn't support RoCE v1, only RoCE v2.

I can't think of a better place.

Correct, We support only RoCEv2 in the latest version of Soft-RoCE.
