Well, I don't plan to do any kernel building while on battery and I am sure that a proper set of patches would allow me to configure when I want throttling i.e. I could configure cpufreqd or whomever to have throttling disabled while on AC and enabled while on battery ;-). > I haven't any measurement but I'm pretty sure you can find something > online (especially related to the P4 clock modulation which only allows > throttling, and in this regard I'm in favour of throttling too as my > desktop's P4 heats very fast). TBH, I am not that keen to look for such things as long as I can't benefit from the results :-/ - -- Regards, EddyP ============================================= "Imagination is more important than knowledge" A.Einstein -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFF2D8uY8Chqv3NRNoRAlsaAJ0cXgdxkFhJ2MNL2mfkrt4KciI+TACdG0U+ sfrTTtOJ6EYsX7rvsPC1NaY= =MLeB -----END PGP SIGNATURE----- -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
