Hi all,
I'm trying to use cpufreq on my Geode GX1 board with linux-2.6.12.5, but,
while everything seems OK, i.e., I can change from performance to powersave
governor and back and /proc/cpuinfo reports me frequency changes, I can
get no effective frequency/CPU power change because I check it with
the Whetstone benchmark and it allways give me the same value (~100 MWIPS).
Any ideas from were could be the problem?
Some additional info follows:
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
performance
$ cat /proc/cpuinfo
