I'm now thinking that defaulting to a high latency sleep state would sort of be required by the pm_qos API -- after all if nobody registers a latency requirement then there is no latency requirement! I think we need some GUI though to adjust this -- like the "inhibit screensaver" applet that exists -- so that users of applications that don't register requirements can still do something useful. johannes --=-ovaRWymvDsICFdRZS3dx Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Comment: Johannes Berg (powerbook) iQIcBAABAgAGBQJJ0kSqAAoJEKVg1VMiehFYcbsP/RXnBhXlk78vqvx+bIfFCaK+ mTDWZfnYjiYxwrBcThjbEf6BlE2vQ5Z10V7DPK7RxFjXurEdD0nzgOS5v7QmePXB 7+etR74vJewwwd2Uj7AfnvTXyeMgs9ig4q/4ITCLqv3gLSxWSt1N1kNDwAnypc8e X6JAQvDQ21lzvbWFR4KnSu0aIJqChHEWptNDpn4mMEKhRBN+vhsO1FMUHcJl09IC oGndi3b8DGb366G9sh6zGba7Z5jdvaIJl8InaNy5/qVDCByj6/mFBOaHXoS2NH73 fE/N/LwpPlKhbl6/QbJW7yOh0apOdwsbCM2NuL2764QJlLcDbxzkhlAmpdovwhFJ sC+XI3CSt/Ukv/Q2PGcrt4wExde5ibk3Wf97yCJw3bA6P3W625rkilGFe/usGmEL LYikBM2cWKp3tyVa10eElQa919iq9MRwRkp9Pjo6UocXwVgzYd5V9q1i8OtpAmwY BtBhKebN8EBg9tVyl53vzaAO9cvr+oaC6r51eB+0mNy3j837kuwG3xJK/QxwqT/n Wxo7HJt3DclsUQImfQjwGd/KtCalcUYFTKaVl5lT1o/rxDlL2De/+ggoHp/lhgE7 tUoCO30Q3ElrO+xzVkrkhX8tpj004Ki1VJSvTnJqKSlEMCMgtPF4L6TjYADyE4bE HCGwK4HUXrfJYRfTM+KB =6s1Z -----END PGP SIGNATURE----- --=-ovaRWymvDsICFdRZS3dx--
