For the most part we have been developing in vanilla recent kernel.org trees when we are testing rxe<->rxe. To talk to ConnectX we need to use the OFED-rdmaoe environment and then we have to play with symvers. If support for ConnectX-en with rdmaoe were upstream then we would only use those kernels. -----Original Message----- From: Roland Dreier [mailto:rdreier-FYB4Gu1CFyUAvxtiuMwx3w@public.gmane.org] Sent: Thursday, December 17, 2009 3:26 PM To: Robert Pearson Cc: 'Jason Gunthorpe'; 'frank zago'; linux-rdma-u79uwXL29TY76Z2rM5mHXA@public.gmane.org; 'John Groves' Subject: Re: [Announce] rxe dev tree available (soft RDMAoE) > Yes, but later.

I think you would probably be better off developing the kernel driver as a branch in an up-to-date kernel tree, and then worrying about backports later. You could get rid of some of the redundant infrastructure like dump_hex() and crc32 (too bad IB didn't choose the CRC32C polynomial, so you can't use the crypto API and get Intel CRC32 instruction acceleration for free). - R. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
