Hello list,
I was trying to get some power savings working on my AR7161 chipset
using OpenWRT, but I was unsuccessful.
Since mips24kc supports the wait instruction, shouldn't sleeping be
supported too? Is anyone working on this platform currently?
Thanks,
Harsha

The two things are pretty much unrelated. The WAIT instruction is used
by the architecture specific code when there is no process available
that could use the CPU. The power managment code deals with all other
aspects of power saving. The two don't even know about each other.
