Since the OFED-1.5 kernel sources are based on 2.6.30, there is an assumption in the configure logic that no backports
are needed for 2.6.30. The cxgb4 src base, however, is from the 3.0 kernel. So yes, you need to add a 2.6.30 (and i
guess a 2.6.29) backports tree in kernel_patches/backports and kernel_addons/backports as needed to get cxgb4/iw_cxgb4
compiling. Further, the config script _might_ need to change to know about these new backports. I'm not sure. I _think_
it should just work once it finds a kernel_patches/backports/2.6.30 directory.

Hi All,
I am trying to back port Chelsio’s cxgb4 driver for 2.6.29 and 2.6.30 kernels to include them in coming OFED-1.5.4
release. I found that my ofed kernel is not getting configured for 2.6.29 and 2.6.30 kernels. i.e when i execute
“./configure <configure options>” it doesn’t apply any patches to any drivers. Release notes for OFED-1.5.4 says that
supported kernels are from 2.6.29 to 2.6.39. I am able to configure kernels from 2.6.31 to 2.6.39.
Is this an expected behaviour or we require fixes in configure script?
Following are the steps i follow to generate ofed_kernel.tgz file and build
ofed_kernel.
1.[root@hpc-cn4 linux-2.6]# backports=none ./ofed_scripts/ofed_makedist.sh
<output removed>
2.[root@hpc-cn4 linux-2.6]# tar xf ofed_kernel.tgz
3.[root@hpc-cn4 linux-2.6]# cd ofed_kernel
4. [root@hpc-cn4 ofed_kernel]# cat /etc/infiniband/info
prefix=/usr
Kernel=2.6.18-128.el5
Configure options: --with-core-mod --with-user_mad-mod
--with-user_access-mod --with-addr_trans-mod --with-mthca-mod
--with-mlx4-mod --with-mlx4_en-mod --with-cxgb3-mod
--with-nes-mod --with-qib-mod --with-ipoib-mod --with-sdp-mod
--with-srp-mod --with-srp-target-mod --with-rds-mod
--with-nfsrdma-mod
5. [root@hpc-cn4 ofed_kernel]# ./configure --with-core-mod --with-user_mad-mod
--with-user_access-mod --with-addr_trans-mod --with-mthca-mod
--with-mlx4-mod --with-mlx4_en-mod --with-cxgb3-mod
--with-nes-mod --with-qib-mod --with-ipoib-mod
--with-sdp-mod --with-srp-mod --with-srp-target-mod
--with-rds-mod --with-nfsrdma-mod
<output removed>
6. [root@hpc-cn4 ofed_kernel]# make&& make install
<output removed>
[root@hpc-cn4 ofed_kernel]# reboot
Thanks,
Vipul
