Dominik Brodowski 7fe2f6399a cpupowerutils - cpufrequtils extended with quite some features
CPU power consumption vs performance tuning is no longer
limited to CPU frequency switching anymore: deep sleep states,
traditional dynamic frequency scaling and hidden turbo/boost
frequencies are tied close together and depend on each other.
The first two exist on different architectures like PPC, Itanium and
ARM, the latter (so far) only on X86. On X86 the APU (CPU+GPU) will
only run most efficiently if CPU and GPU has proper power management
in place.

Users and Developers want to have *one* tool to get an overview what
their system supports and to monitor and debug CPU power management
in detail. The tool should compile and work on as many architectures
as possible.

Once this tool stabilizes a bit, it is intended to replace the
Intel-specific tools in tools/power/x86

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
- Adjust README
- 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
