I am searching the linux version to support clock and power management(CPM) of PPC405.

Linux kernel use the cpu_idle() function when the cpu don¡¯t have any task to do..

And, the implementation of cpu_idle() is different between each architecture.

I cannot find whether latest ppc tree of linux support CPM or not¡¦.

If the official linux support CPM of PPC405, Do Mvista, Red hat, fedora, gentoo support CPM of PPC405?
