Hi, I would like to obtain fore mentioned data from within my module. I need these performance metrics to see how certain code executes, and make decisions during the runtime. pmc(3) seems complete, but it also seems to be intended for use in the userland. How to use pmc from modules? Is there any other way? Also, module is amd64 only, so I don't care about portability. Cheers, Nikola
