<!-- pstate values:
12
* 0-2: real pstates
13
0: p1 100 MFlops/s, [idle: 95W -> full burning: 200W]
14
1: p2 50 MFlops/s, [idle: 93W -> full burning: 170W]
15
2: p3 20 MFlops/s, [idel: 90W -> full burning: 150W]
16
17
* 3: booting up was measured to take 150s and 18000J.
18
So we create a pstate 3 consuming 18000J/150s=120W, and a boot remains at this pstate for 150s.
19
Speed is set at 0 flop/s so that nothing progresses during the boot.
20
* 4: shutting down was measured to take 7 s and 770 J
21
So we create a pstate 4 consuming 770J/7s=110W, and a shutdown remains at this pstate for 7s.

23
Please note that even if these values are educated guesses, you should still challenge them.
24
If you want a realistic simulation, you must use values coming from a real benchmark of your platform.
