| config CPU_FREQ_CBE | |
| tristate "CBE frequency scaling" | |
| depends on CBE_RAS && PPC_CELL | |
| default m | |
| help | |
| This adds the cpufreq driver for Cell BE processors. | |
| For details, take a look at <file:Documentation/cpu-freq/>. | |
| If you don't have such processor, say N | |
| config CPU_FREQ_CBE_PMI | |
| bool "CBE frequency scaling using PMI interface" | |
| depends on CPU_FREQ_CBE | |
| default n | |
| help | |
| Select this, if you want to use the PMI interface to switch | |
| frequencies. Using PMI, the processor will not only be able to run at | |
| lower speed, but also at lower core voltage. | |
| config CPU_FREQ_MAPLE | |
| bool "Support for Maple 970FX Evaluation Board" | |
| depends on PPC_MAPLE | |
| help | |
| This adds support for frequency switching on Maple 970FX | |
| Evaluation Board and compatible boards (IBM JS2x blades). | |
| config CPU_FREQ_PMAC | |
| bool "Support for Apple PowerBooks" | |
| depends on ADB_PMU && PPC32 | |
| help | |
| This adds support for frequency switching on Apple PowerBooks, | |
| this currently includes some models of iBook & Titanium | |
| PowerBook. | |
| config CPU_FREQ_PMAC64 | |
| bool "Support for some Apple G5s" | |
| depends on PPC_PMAC && PPC64 | |
| help | |
| This adds support for frequency switching on Apple iMac G5, | |
| and some of the more recent desktop G5 machines as well. | |
