(New subscriber to the list. Could not find a relevant-looking
FAQ. Searched 25MB of archives before sending. Apologies if I
have the wrong list or am guilty of some other infraction.)
Attempting to set up a pair of machines to do NVMf experiments
with Chelsio T580-LP-CR NICs. Was instructed to use CentOS 7.2,
the Chelsio hardware-specific driver modules, and the
git-snapshot-nvmf-all.3 "NVMe over Fabrics RDMA target support"
module(s). Preliminary testing with Chelsio's binary RPMs (their
rbdi and rbdt modules) worked well.
The git-snapshot-nvmf-all.3 tar archive is kernel 4.7.0-rc2, but
Chelsio's source modules require kernel 4.1 or before. The
NVMf-RDMA-enabled 4.7.0-rc2 kernel built, booted, and is running
well. However, attempts to build the Chelsio NIC modules have
failed--even after modifying the Python configuration script to
not choke when trying to build for kernel 4.1.
To attempt to reconcile the kernel versions, I downloaded this
v4.1 tag snapshot:
http://git.infradead.org/nvme-fabrics.git/snapshot/b953c0d234bc72e8489d3bf51a276c5c4ec85345.tar.gz
However, "make menuconfig" does not show any options resembling
"NVMe over Fabrics RDMA target support" that I could discern.
If necessary, I'm willing to modify the Chelsio driver source to
make it work with kernel 4.7.0-rc2, but I'm suspicious that would
be a rathole.
Any suggestions? What do I not understand about how to get a
kernel that talks to the cards and does "NVMe over Fabrics RDMA
..."? Is there any chance the git-snapshot-nvmf-all.3 kernel
4.7.0-rc2 can talk directly to the cards without the Chelsio
modules?
Thanks,
Robert Riches

If so, please see kernel.org and get the latest mainline 4.8rc build
and start from there.

Yes, you can use linux-4.8-rc7 and use the chelsio drivers from that kernel.
Steve.
