Without being able to access the bios, on a server running CentOS 6.4, is there any way to disable the C6 and C7 power saving states from the kernel?On my install this does not exist:
So I've got a problem where I get an annoying whine when my CPU goes into C3/C6 states. Now I can disable these in the BIOS and this solves the problem on Windows. However the Intel drivers on Linux don't seem to respect this and I still get the horrible whine. As soon as I stress the CPU it's instantly gone.
So I noticed when I went to go use one of my apps that uses GPS the other day it said the phone had to come out of power saving mode to turn on the GPS, so I did that. Now I can't seem to find where to enable and disable Power Saving. I am not talking about the Extreme Power Saving feature that we don't have yet, just the normal power saving feature.
