Hi there!
Hope someone out there can give me some pointers here. I've got a 2.6.18 kernel on a ppc 8555, which I configured to enable power management (CONFIG_PM=y). After doing that, the file /sys/power/state appears on my file system. If I cat the file I get "standby mem" (without the quotes), but if I try to write to it (to change the state) I get an EPERM. I assume it is because I have no code that implements any power save mode changes, only the interface to change them. Am I wrong? How can I tell for sure? (the file is writable, so it is not a problem with writing permissions) So the question is (if I am right) where do I get the code from? I am hoping someone has implemented power save for that processor already, but I just don't know where to start looking for that code. Can someone help? Thanks very much in advance. Marta Chamorro.
