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?

It does not.

You would have to ask Monta Vista or Wind River if they do. Red Hat,
Fedora, and Gentoo don't support PPC405 at all.
