[Vasiliy Tolstov]

Hello. I want to develop some software under linux 3.14 and using
infiniband libraries. I'm download latest ofed (3.12 ?) and see that
some packages i don't need (i'm use only mellanox connect x3)
But i can't understand in case of linux 3.14 does i need compat-rdma ?

You can use the inbox libraries and install them through your distro 
package installer, with RHEL, Fedora and such
it would be just

$ yum groupinstall "infiniband support"

to get you the set of required RPMS [1] SLES and Ubuntu should have 
similar means, no need to use OFED, compat, etc.

Or.

[1] you mentioned ConnectX-3, so your basic needs are libmlx4, 
libibverbs and librdmacm

AF_IB was merged in 3.11, BTW - can you share what's your motivation to 
use it? as for rsockets, basically any kernel thatsupports the rdma_cm 
along with it's user-space device, this goes a while back... you 
mentioned 3.14, should be OK

I'm try to modify sheepdog and qemu to allows via name name guid and
establish communication with remote node without IPoIB.
But my knowledge about rdma not very good, and i try to see sources
and write simple app =).

Hello Vasiliy,

A possible alternative is to start from a recent upstream kernel and to
build and install the latest RDMA libraries from the upstream git
repositories. I have attached the script I use myself since considerable
time to install the latest RDMA libraries on openSUSE systems.

Bart.

Nice! Thanks. I'm recheck my build (i'm already build all needed stuff).
