Subject: Performance Stats: Kernel patch
Hello collogues,
Patches make available to the user the following new per-process
(thread) performance statistics:
* Involuntary Context Switches
* Voluntary Context Switches
* Number of system calls
This data is useful for detecting hyperactivity patterns between processes.
I have attached 3 patches perf_stat.patch, perf_stat_x86_64.patch and
perf_stat_ppc.patch for linux-2.6.21-rc5
and corrected all notes which were before. Do you have any objections?
I need your opinion again.
Best regards,
Maxim Uvarov.
