I used to use powernowd (userspace daemon) on all my past builds, but this time I gave it a try without. Now I'm just echoing 'ondemand' to /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor and as the line above shows it idles at the slow speed. But it ramps up to its full speed (1800 MHz) doing 'tar -xvf', only to fall back. It also ramps up running configure scripts, unlike my x86 boxes. This is with a 3.10.12 kernel. So no, I haven't seen the patch and I appear not to need it. Unfortunately, even at full speed it still takes for ever to compile things (just over 8 hours to build and install firefox-24). ĸen -- das eine Mal als Tragödie, dieses Mal als Farce _______________________________________________ Clfs-dev mailing list [email protected] http://lists.cross-lfs.org/listinfo.cgi/clfs-dev-cross-lfs.org
