running powernowd on debian lenny
I have a cq40-115au latop with AMD Turion x2 RM-70 processor. I want to enable powernowd. After i compiled it from source, when i ran # powernowd here are the output: powernowd: PowerNow Daemon v1.00, (c) 2003-2008 John Clemens /sys/devices/system/cpu/cpu0/cpufreq/affected_cpus: No such file or directory powernowd: err=2 powernowd: Found 2 scalable units: -- 1 'CPU' per scalable unit /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq: No such file or directory PowerNowd encountered and error and could not start.

After i compiled it from source Because you built your own, it becomes more difficult for the rest of us to help you. The Debian 'powernowd' package has been altered from upstream to put its configuration options in /etc/default/powernowd. My answers below are from my own experiences using the Debian 'powernowd' package; you will have to read the documentation in the source code, and figure out how to translate my answers to work for your own setup. (In my view, it was a waste of time for you to compile your own 'powernowd', since Debian already has the package.) i had removed it (now) with #make clean #rm -f /usr/bin/powernowd and installed powernowd package, enabled needed modules #modprobe cpufreq_userspace powernow-k8 So, did that work or not? , when i ran # powernowd here are the output: powernowd: PowerNow Daemon v1.00, (c) 2003-2008 John Clemens /sys/devices/system/cpu/cpu0/cpufreq/affected_cpus: No such file or directory powernowd: err=2 powernowd: Found 2 scalable units: -- 1 'CPU' per scalable unit /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq: No such file or directory PowerNowd encountered and error and could not start.

Check 'dmesg' for errors. # uname -r 2.6.26-2-686-bigmem I assume that is a Debian kernel? The default CPU_FREQ_GOV* settings have changed over time. What do you get if you run this: grep CPU_FREQ /boot/config-2.6.26-2-686-bigmem CONFIG_CPU_FREQ=y [...] CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y # CONFIG_CPU_FREQ_DEFAULT_GOV_POWERSAVE is not set # CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set # CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND is not set # CONFIG_CPU_FREQ_DEFAULT_GOV_CONSERVATIVE is not set CONFIG_CPU_FREQ_GOV_PERFORMANCE=y CONFIG_CPU_FREQ_GOV_POWERSAVE=m CONFIG_CPU_FREQ_GOV_USERSPACE=m CONFIG_CPU_FREQ_GOV_ONDEMAND=m CONFIG_CPU_FREQ_GOV_CONSERVATIVE=m So, you have an old kernel that defaults to performance. That will cause your CPU to run at full speed, instead of cycling down when not needed. What is in /etc/fstab? If you installed using a Debian installer, you should have a line like this: sysfs /sys sysfs defaults 0 0 # file system mount point type options dump pass proc/proc procdefaults0 0 /dev/sda1 / ext3errors=remount-ro 0 1 /dev/sda2 /home ext3defaults0 2 /dev/sda5 noneswapsw 0 0 /dev/scd0 /media/cdrom0 udf,iso9660 user,noauto 0 0 sysfs /sys sysfs defaults 0 0 Looks OK. # mount -t sysfs none /sys mount: none already mounted or /sys busy mount: according to mtab, sysfs is already mounted on /sys Yep, you already had /sys... no need to try to mount it again. What should I do next? If the 'sysfs' line is missing from /etc/fstab, add it then mount it using 'mount /sys'. With Debian kernels, you need to add two lines to /etc/modules to make it possible for 'powernowd' to run with recent AMD CPUs: cpufreq_userspace powernow-k8 You can load these without rebooting using 'modprobe'. (I build my own kernels, so when I _used_ to use 'powernowd', I simply built these options directly into the kernel.) If you were using 'powernowd' packages from Debian, you could edit /etc/default/powernowd to enable loading the program during the boot sequence and to customize its settings. Since you built your own 'powernowd', tweaking the configuration may involve editing a bootscript or something. (You're on your own here: RTF docs.) One last thought. I played with 'powernowd' for a while. I liked it well enough. Then I found out that the Linux kernel has the CPU_FREQ_GOV_ONDEMAND driver, which can be built into the kernel or used as a loadable module. Debian kernels began defaulting to it a while ago, though your kernel may be old enough that it was not yet using it by default. I decided that 'powernowd' was superfluous, and began using 'cpufreq_ondemand' and never looked back. My advice would be that you do the same. So, did any of this work? After letting the machine idle for a few seconds, run this:

I do not know exactly your situation but wireless connection breakage may be different issue. I have backported network-manager installed. This type of software should reconnect. If you are using barebone ifupdown and /etc/network/interfaces, this may not respond to breakage easily unless you dd very fancy set-up.

Definitely. If your setup was correct, it would be working.

That will cause your CPU to run at full speed, instead of cycling down when not needed. this had caused my laptop to shutdown when playing games like secret maryo chronicles That would be an overheating issue. You have a hardware problem with your laptop not keeping itself cool. CPU frequency controlling software is meant to extend your battery life, not to act as a bandaid for inadequate CPU cooling. Any time that you start using your laptop heavily, the software will boost the frequency and you will have the same problems with shutdowns anyway. The only problems that will be solved by running 'powernowd' (or switching to CPU_FREQ_ONDEMAND) are longer battery life and lower temps when not being used for demanding tasks. What is in /etc/fstab? If you installed using a Debian installer, you should have a line like this: sysfs /sys sysfs defaults 0 0 # file system mount point type options dump pass proc/proc procdefaults0 0 /dev/sda1 / ext3errors=remount-ro 0 1 /dev/sda2 /home ext3defaults0 2 /dev/sda5 noneswapsw 0 0 /dev/scd0 /media/cdrom0 udf,iso9660 user,noauto 0 0 sysfs /sys sysfs defaults 0 0 Looks OK. the last line was just added by me Oh, I misinterpreted your response as meaning it was already in 'fstab'.
