I'm trying to get perfmon2 to work with Nehalem EX. # more /proc/cpuinfo vendor_id : GenuineIntel cpu family : 6 model : 46
It is clear that the latest releases do not support this processor. I'm trying work around the problem by getting the latest and greatest code. Is this the right approach? Is this processor even supported with the latest code? Here's what I'm working with: pfmon - top of trunk 5/12/2010 pflib - top of trunk 5/12/2010 perfmon2 - 2.6.29 patch As far as I can tell, I have the correct versions of pfmon and pflib - that is they support my CPU. The problem is that the kernel oopses when I try to monitor anything. It's pretty clear that the 2.6.29 kernel does not support model 46. However, I think that the latest pfmon snapshot DOES. Is this correct? I tried getting the latest from the git repository (2010-04-09 commit). I must be doing something wrong, because the kernel does not compile. I get all sorts of errors in random parts of the code (infiniband, IPv4 netfilter, etc). I started off fixing these errors my modifying .config and merely setting CONFIG_ABC=n. This is not the correct solution though - when I fix one error, more crop up. Can someone give me a sanity check that compiling the 4/9/2010 snapshot works? Will the 4/9/2010 snapshot work with Nehalem EX, model 46? Is the 4/9/2010 snapshot compatible with the latest pfmon/pflib? Am I even taking the right approach to solving this problem? Thanks for your help! -David
