Hi, I own an Compaq Presario 920EA laptop with an Athlon XP 2000+ mobile processor. It uses AMD's PowerNow! speedstepping technology to preserve battery power when the system load is low. This works just fine in Windows XP since there is a driver (amdk7.sys) for the CPU feature, but I don't think there is one for Linux (??). I would like to install Gentoo on my laptop (I have gentoo on all my other desktop PCs), but if that results in an ever-running (and noisy!) CPU fan and short battery life time, I need to think twice about it. What's the state of the PowerNow! technology on Linux kernels (2.4 series) ? If there is support, does it scale automatically, like in Windows, based on system load ? This is really the only thing stopping me from installing Linux on my laptop.
Any input appreciated, thanks. Øyvind -- < Øyvind Stegard <[EMAIL PROTECTED]> < University of Oslo, Dept. of informatics. < http://heim.ifi.uio.no/~oyvinst < "Education: the path from cocky ignorance < to miserable uncertainty." - Mark Twain -- [EMAIL PROTECTED] mailing list
