Hi;
I am trying run the netperf SDP_STREAM test between a
pair of Chelsio S310-SR iWARP cards in x86_64 hosts
(CentOS 5.0, OFED 1.2).
My netperf client command starts like so:
[EMAIL PROTECTED] ~]# LD_PRELOAD=/usr/lib64/libsdp.so
/opt/netperf/bin/netperf -l 10 -H xx.xx.xx.xx -L yy.yy.yy.yy -c -C -t
SDP_STREAM
SDP STREAM TEST from yy.yy.yy.yy (yy.yy.yy.yy) port 0 AF_INET to
xx.xx.xx.xx (xx.xx.xx.xx) port 0 AF_INET
And then the client panics. The RIP on the console refers to
ib_sdp:sdp_connected_handler, and I can see rdma_cm:cma_iw_handler
and iw_cm:cm_work_handler in the traceback. From strace on the
client, the last output I get is:
connect(8, {sa_family=AF_INET, sin_port=htons(12865),
sin_addr=inet_addr("128.227.253.92")}, 128
I can see the connection on the netserver host in sdpnetstat:
Proto Recv-Q Send-Q Local Address Foreign Address
sdp 0 0 xx.xx.xx.xx:51804 yy.yy.yy.yy:48590
My libsdp.conf on both hosts is very simple:
use both server * *:*
use both client * *:*
The hosts I'm using also have 4X SDR IB HCAs (mthca),
if that matters. The SDP_STREAM test runs perfectly
over IB.
Is SDP on iWARP supposed to work in OFED 1.2? Any advice
or hints on getting it working would be most appreciated.
Unfortunately, SDP over Chelsio's iWARP rnic hasn't been tested at all
and is not supported.
Also, if you want to use RDMA over Chelsio's rnic, I recommend you get
the latest 1.2.5.4 daily build which has all the current cxgb3 fixes
included.
Alsoalso, Chelsio has TOE/Sockets drivers available on their web site to
support full TCP offload via the sockets interface. Checkout
http://service.chelsio.com for the source.
Steve.
