Hi all:

We have a user who needs to do some work with PAPI, which requires the perfctr patch applied to the kernel proper. Before I do that work here, I wanted to ask the list if anyone knows of a repo where such kernels are available?

Also, if anyone has gone down this route and has helpful hints, perspectives, horror stories, etc., I would covet that information also.

I know almost nothing about PAPI, but just wonder if oprofile can do the job. If so, it would make things easier because oprofile is included. If you indeed need perfctr, then please refer to:

http://wiki.centos.org/HowTos/Custom_Kernel

to rebuild the kernel CentOS way.
