Hi;

Before the holidays, I tried a netperf SDP_STREAM
test between a pair of Chelsio S310-SR iWARP cards
using OFED 1.2, which crashed the netperf client
host.  Using OFED-1.3-20080107-0942 on both hosts
the crash no longer happens, which is great, but it
isn't working quite yet:

Hey Craig,

SDP currently isn't suppored over the Chelsio RNICs. No testing has been done.


Hi Steve;

I understand - just following up on the short thread from
before the holidays where I started looking at this.

That was sooo last year. :)

I'm interested to try to make it SDP work anyway on these RNICs
for a project we are working on.  I am willing to put in some
time to work on this and (if successful) do some testing and
report back (if anyone is interested), and would be grateful
for any advice or help from this list.


Ok. First make sure the sdp kernel module uses the rdma cma. Then I'd add printk hooks in cma.c, addr.c, and iwcm.c to see what's going on and where things are failing. Also a wire trace is good if we're getting that far (like at least doing arp resolution).

I haven't looked at the sdp code at all, so you'll have to do the leg work.

Thanks!

Steve.



Cheers,
Craig
