2 tristate "CBE frequency scaling"
3 depends on CBE_RAS && PPC_CELL
4 default m
5 help
6 This adds the cpufreq driver for Cell BE processors.
7 For details, take a look at <file:Documentation/cpu-freq/>.
8 If you don't have such processor, say N

11 bool "CBE frequency scaling using PMI interface"
12 depends on CPU_FREQ_CBE
13 default n
14 help
15 Select this, if you want to use the PMI interface to switch
16 frequencies. Using PMI, the processor will not only be able to run at
17 lower speed, but also at lower core voltage.
