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.
config PPC_PASEMI_CPUFREQ
bool "Support for PA Semi PWRficient"
depends on PPC_PASEMI
default y
help
This adds the support for frequency switching on PA Semi
PWRficient processors.
config POWERNV_CPUFREQ
tristate "CPU frequency scaling for IBM POWERNV platform"
depends on PPC_POWERNV
default y
help
This adds support for CPU frequency switching on IBM POWERNV
platform
