Hi Steve, I have tried the things you have suggested for 2.6.30 kernel and it worked. :)
Thanks, Vipul -----Original Message----- From: Steve Wise [mailto:[email protected]] Sent: 04 August 2011 19:48 To: Vipul Pandya Cc: [email protected]; Kumar A S Subject: Re: 2.6.29 and 2.6.30 kernel support 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. Steve.

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.
