Writing to power/autosuspend only makes sense if it's currently set to -1. > or do we currently (new kernels etc) want to stop setting power/level to > "auto" as > well? This still leaves the kernel in charge. Right, but the problem here is that the kernel will then suspend idle input devices - and the common case is that you don't want that to happen. powertop would need to carry its own white or blacklist of drivers and devices if it's going to enable that. We default autosuspend off on most devices because it can be dangerous. -- Matthew Garrett | [email protected] _______________________________________________ Power mailing list [email protected] http://www.bughost.org/mailman/listinfo/power
