But a lot of SoC like 440GT/EX support two modes of power save -
- Cut off power to other cores like PCIExpress/USB/MAC/UART etc
- Lower the CPU frequency
Is it possible to scale down CPU freq or cut off power to unused cores
while the CPU is idle? The ideal way would be that the SoC registers a

Hi all,
I would like to know whether Linux on PowerPC puts the processor on
low power mode during idle state. Most PowerPC processors support a
low power mode. I am looking to add support for low-power mode in
Linux for AMCC 4xx processors.
My questions are the following:
1) Is tickless kernel int
