ozkanonur 101025ff8e tools/power/cpupower/{ToDo => TODO}: Rename the todo file 
Renamed the to-do file to 'TODO' instead of 'ToDo' to
comply with the naming standard.

ToDos sorted by priority:

  • Use bitmask functions to parse CPU topology more robust (current implementation has issues on AMD)
  • Try to read out boost states and frequencies on Intel
  • Somewhere saw the ability to read power consumption of RAM from HW on Intel SandyBridge -> another monitor?
  • Add another c1e debug idle monitor -> Is by design racy with BIOS, but could be added with a --force option and some "be careful" messages
  • Add cpu_start()/cpu_stop() callbacks for monitor -> This is to move the per_cpu logic from inside the monitor to outside it. This can be given higher priority in fork_it.
  • Fork as many processes as there are CPUs in case the per_cpu_schedule flag is set. -> Bind forked process to each cpu. -> Execute start measures via the forked processes on each cpu. -> Run test executable in a forked process. -> Execute stop measures via the forked processes on each cpu. This would be ideal as it will not introduce noise in the tested executable.
