3 tristate "CBE frequency scaling"
4 depends on CBE_RAS && PPC_CELL
7 This adds the cpufreq driver for Cell BE processors.
8 For details, take a look at <file:Documentation/cpu-freq/>.
9 If you don't have such processor, say N
11 config CPU_FREQ_CBE_PMI
12 bool "CBE frequency scaling using PMI interface"
13 depends on CPU_FREQ_CBE
16 Select this, if you want to use the PMI interface to switch
17 frequencies. Using PMI, the processor will not only be able to run at
18 lower speed, but also at lower core voltage.
21 bool "Support for Maple 970FX Evaluation Board"
24 This adds support for frequency switching on Maple 970FX
25 Evaluation Board and compatible boards (IBM JS2x blades).
28 bool "Support for Apple PowerBooks"
29 depends on ADB_PMU && PPC32
31 This adds support for frequency switching on Apple PowerBooks,
32 this currently includes some models of iBook & Titanium
35 config CPU_FREQ_PMAC64
36 bool "Support for some Apple G5s"
37 depends on PPC_PMAC && PPC64
39 This adds support for frequency switching on Apple iMac G5,
40 and some of the more recent desktop G5 machines as well.
42 config PPC_PASEMI_CPUFREQ
43 bool "Support for PA Semi PWRficient"
47 This adds the support for frequency switching on PA Semi
48 PWRficient processors.
50 config POWERNV_CPUFREQ
51 tristate "CPU frequency scaling for IBM POWERNV platform"
52 depends on PPC_POWERNV
55 This adds support for CPU frequency switching on IBM POWERNV
