5 Quick guide for the impatient:
8 controls the boost setting for the whole system. You can read and write
10 Reading or writing 1 does not mean that the system is boosting at this
11 very moment, but only that the CPU _may_ raise the frequency at it's
17 Some CPUs support a functionality to raise the operating frequency of

29 Though the idea is to just give better performance without any user
30 intervention, sometimes the need arises to disable this functionality.
31 Most systems offer a switch in the (BIOS) firmware to disable the

41 3. Boosting means overclocking the processor, though under controlled
42    conditions. By raising the frequency and the voltage the processor
43    will consume more power than without the boosting, which may be

51 To allow the user to toggle the boosting functionality, the cpufreq core

60 This will either disable the boost functionality on all cores in the
61 whole system (0) or will allow the software or hardware to boost at will
64 Writing a "1" does not explicitly boost the system, but just allows the
66 factors like the chip's temperature into account, so boosting once does

91 Technically it is possible to switch the boosting functionality at least
92 on a per package basis, for some CPUs even per core. Currently the driver
93 does not support it, but this may be implemented in the future.
