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. Cheers and Thanks, Dave Thompson UW-Madison Computer Sciences Department
