1 | config CPU_FREQ_CBE |
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 | |

10 | config CPU_FREQ_CBE_PMI | |
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. | |
