I believe today they differ in turning whole devices on or off, but there are some of those devices that could be put in reduced-function/lowered-speed modes if we were ready to use a finer-grained distinction. This is, of course, in an embedded framework rather than a desktop framework - we suspend and wakeup automatically, not via user intervention. Answering a question asked in another piece of mail, we have roughly a dozen different devices that cause the system to wakeup - keypad press, touchscreen touch, flip open/close, etc. And, PCI is totally alien to us... scott -----Original Message----- From: Pavel Machek [mailto:pavel@ucw.cz] Bring example hardware that needs more than two states, implement driver support for that, and then we can talk about adding more than two states into core code. Pavel And from another mail: Out of curiosity, are there really cases where there is > 1 wakeup device? -- Thanks, Sharp!
