Now I would like see the current CPU speed. I also liked to change it, because I believe it will have an affect on throughput. I tried cpufreq but it wasn't very helpful: /sys/devices/system/cpu/cpu0/cpufreq# cat cpuinfo_cur_freq /sys/devices/system/cpu/cpu0/cpufreq# Is it possible to change CPU speed in latest linux-omap kernels? I'm using N800 and omap-2.6.29 branch from linux-omap tree. -- Kalle Valo
