One other quick thought, which I had mentioned earlier to Kalesh: 3) Make the semantics a process holding open a file descriptor, rather than writing 0/1 into a file. It'd be called /sys/power/ userspace_autosleep_ctrl, or something, and it'd enable this behavior while it's opened. And maybe down the line somebody will want to add ioctls to it for a different purpose. This way it's less of a tunable and more of an indication that there's a userspace app doing/controlling something. This idea (3) may be a lot of added complexity for basically nothing, but it might fit the usage semantics concerns a bit better than (2). But anyway, just an idea. Any one of those three are fine with me. Jason
