13 Some options are platform wide, some affect single cores. By default values
14 are applied on all cores. How to modify single core configurations is
15 described in the cpupower(1) manpage in the \-\-cpu option section. Whether an
16 option affects the whole system or can be applied to individual cores is

30 The range of valid numbers is 0-15, where 0 is maximum
33 The processor uses this information in model-specific ways
34 when it must select trade-offs between performance and
38 (P-states) or CPU Idle power states (C-states), but allows
44 in the "turbo range" above the explicitly OS-controlled
45 P-state frequency range.  It may also tell the hardware
46 how aggressively it should enter the OS requested C-states.
48 This option can be applied to individual cores only via the \-\-cpu option,
