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.
