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.
Thanks for the advice! I will try out the 1.2.5.4 daily build
on our hosts with the Chelsio RNICs and visit service.chelsio.com.
I am still interested in SDP on iWARP, though - are there any
OFED-supported RNICs over which SDP would work?
Chelsio is the only iWARP driver in ofed-1.2.x. ofed-1.3 has NetEffect
too. Dunno if they support SDP.
If you go up to 1.2.5.4 or ofed-1.3-rc1 and try out SDP over chelsio,
I'll help ya debug stuff as time permits.
As I mentioned, the nodes with the Chelsio RNICs also have mthca
devices connected to our IB fabric. Are 1.2 and 1.2.5.x meant to
be interoperable?
They should be. Its just that there are a few dozen bug fixes from 1.2
to 1.2.5.4 in the chelsio drivers. Also, if you go up to 1.2.5.4,
you'll need the 5.0 firmware from cheslio's web site. Pull down the
firmware and put it in /lib/firmware. Then it should get upgraded
automagically.
Stevo.
