It adds an option to PowerTOP allowing behavior to be focused on a specific cpu. As other options, the stability is "Uncommitted", and a release binding of "Patch/Micro".

Name of Document Author/Supplier: Author: Rafael Vanoni 1.3 Date of This Document: 10 February, 2009 4. Technical Description Currently, PowerTOP observes power management related events on a system wide basis. With the growing number of cores and processors in today's system, it is sometimes desirable to observe the system in a finer grained manner. This project introduces a new command line option that allows the user to specify which core/processor he wishes to observe with PowerTOP. The new option will focus all of PowerTOP's subwindows into the specified processor. Therefore, presenting the processor's behavior in terms of idle state and frequency level transitions, as well as reporting only events that affect power management on that CPU. This new option can be specified through the --cpu or -c option, and must be followed by a CPU id. It can be used while specifying a time interval (-t), with dump mode (-d), but not with verbose mode (-v). Proposed man page addition: OPTIONS -c [processor id] Specifies which CPU the tool should observe. EXAMPLES Example 4 Analyzing activity on a specific processor This command will run PowerTOP and only display data for CPU 3. % powertop -c 3 6. Resources and Schedule 6.4.
