To use PowerNow technology included in AMD Turion™ 64 X2 Mobile Technology TL-50 you need to insert some modules into kernel and use userspace powernowd daemon.
Use modprobe to load this modules, and do not forget to include them in /etc/modules.
cpufreq-userspace
powernow-k8
Now test if everything load properly with dmesg | tail. Messages about your processor(s) should appear.
# dmesg | tail
powernow-k8: Found 2 AMD Athlon 64 / Opteron processors (version 1.60.2)
powernow-k8: 0 : fid 0x8 (1600 MHz), vid 0x12 (1100 mV)
powernow-k8: 1 : fid 0x0 (800 MHz), vid 0x1e (800 mV)
cpu_init done, current fid 0x8, vid 0x12
Install powernowd:
# aptitude install powernowd
Note: you may use any CPUfreq policy governor (powersave, conservative, ondemand). I just prefer userspace tool.
Note: to test if it works as expected try:
# invoke-rc.d powernowd stop
Stopping powernowd: powernowd.
# cat /proc/cpuinfo | grep MHz
cpu MHz : 1600.000
cpu MHz : 1600.000
# invoke-rc.d powernowd start
Starting powernowd: powernowd.
# cat /proc/cpuinfo | grep MHz
cpu MHz : 800.000
cpu MHz : 800.000
