1config 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 9 10config 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. 18 19config CPU_FREQ_MAPLE 20 bool "Support for Maple 970FX Evaluation Board" 21 depends on PPC_MAPLE 22 help 23 This adds support for frequency switching on Maple 970FX 24 Evaluation Board and compatible boards (IBM JS2x blades). 25 26config CPU_FREQ_PMAC 27 bool "Support for Apple PowerBooks" 28 depends on ADB_PMU && PPC32 29 help 30 This adds support for frequency switching on Apple PowerBooks, 31 this currently includes some models of iBook & Titanium 32 PowerBook. 33 34config CPU_FREQ_PMAC64 35 bool "Support for some Apple G5s" 36 depends on PPC_PMAC && PPC64 37 help 38 This adds support for frequency switching on Apple iMac G5, 39 and some of the more recent desktop G5 machines as well. 40 41config PPC_PASEMI_CPUFREQ 42 bool "Support for PA Semi PWRficient" 43 depends on PPC_PASEMI 44 default y 45 help 46 This adds the support for frequency switching on PA Semi 47 PWRficient processors. 48 49config POWERNV_CPUFREQ 50 tristate "CPU frequency scaling for IBM POWERNV platform" 51 depends on PPC_POWERNV 52 default y 53 help 54 This adds support for CPU frequency switching on IBM POWERNV 55 platform 56
