I have Ubuntu 12.04 installed on my machine. I want to use lockstat. I have looked at Documentation/lockstat.txt but I am not getting how to use it, if possible please help me out.
I am working on a project adapting system software like the Linux kernel. I read one paper titled "Experience on Comparison of Operating Systems Scalability on the Multi-core Architecture" that tells how to detect bottlenecks using bench-marking. I am following their experimental approach and am able to generate a profiling report using the profile tool, but I am not able to detect bottlenecks from this profiling report.
Basically, I am not able to explore the no-vmlinux part, and I am not able to find no-vmlinux functions related to bottlenecks. Also I am not able to use lockstat.txt as there is no file in /proc/sys/kernel/lock_stat.
