getting path to backport directory

getting path to backport directory

[Robert D. Russell]

A general question on getting the correct backport.

On my machine, if I do "uname -r" I get
2.6.18-128.el5

If I do "cat /etc/redhat-release" I get
CentOs release 5.3 (Final)

If I look in "/usr/src/ofa_kernel/kernel_addons/backport"
the subdirectory I need to use for the current kernel is:
2.6.18-EL5.3

My question:  Is there somewhere in the system where I can
find (or generate) the string "2.6.18-EL5.3"?
I want to put that in my scripts so they will automatically
pick it up whenever we change versions (as we just did when
going to Centos -- it used to be 2.6.18-EL5.2 in the RedHat
version we were running before).  At present I have to edit
these scripts by hand, and that's a lousy way to do business.

Thanks,
Bob Russell

If you have a configured ofa_kernel tree, then look at 
<path_to_ofa_kernel>/config.mk.  It contains the backport path.

Run the script ofed_scripts/get_backport_dir.sh

You can force the ofa-kernel build system to use a specific backport by doing:

ofed_scripts/ofed_patch.sh --kernel-version=2.6.18-EL5.3
./configure ; make ; make install

That is handy if the kernel version contains extra bits that confuses the 
ofed_patch script.

Cheers,

Guy
