That's what the multi-core aware CPU scheduler does. If it is enabled in the kernel config, there should be a file in /sys/devices/system/cpu/ where you can enable it by writing 1 to it (forgot the name and no C2D machine in the neighbourhood). > Additionally it would be possible to undervolt this disabled core > and thus save more watts. Cpufreq already works that way, you only need to enable the multi-core aware scheduler to make better use of it. Erik -- They're all fools. Don't worry.
