Hi Martin,

You can select userspace governor for cpu_freq and change /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed value to change the cpu frequency.

Subject: change cpu_freq

hi,

how can i change the cpu frequency of my osk5912 using the scale_cpu_freq feature of the 2.6.16 kernel? how is the syntax of this? is there a documentation available (except the ones in the documentation folder of my linux directory)?

my next question is, how can i read/write to the regs of the omap5912? during using 2.4 kernel i was able to access the regs directly with a module. but now with 2.6 kernel i get a segmentation fault. maybe someone can help me?

regards

martin
