I've been working on measuring idle power consumption of the
BeagleBoard under different idle states. I have the latest demo kernel
from Angstrom which has CPUIdle enabled. The kernel recognizes 6 C-
states but only seems to use one of those states. The online, offline,
and kernel_max values all seem to suggest that only one of those C-
states is usable.
Any ideas on how to enable the other C-states? Any kernel compile
options I am missing? Is there even support for those other states?
Any help would be greatly appreciated!
