Hi,
My PC is Thinkpad X200 running on Ubuntu 10.10, kernel 2.6.35-22-generic-phc.
I've compiled and installed phc_intel, the module is loaded but i can't see any phc files in /sys/devices/system/cpu/cpu0/cpufreq/.

Code: Select all

~$ cat /sys/devices/system/cpu/cpu0/cpufreq/phc_default_vids 
cat: /sys/devices/system/cpu/cpu0/cpufreq/phc_default_vids: No such file or directory
/sys/devices/system/cpu/cpu0/cpufreq$ ls
affected_cpus               ondemand                       scaling_governor
bios_limit                  related_cpus                   scaling_max_freq
cpuinfo_cur_freq            scaling_available_frequencies  scaling_min_freq
cpuinfo_max_freq            scaling_available_governors    scaling_setspeed
cpuinfo_min_freq            scaling_cur_freq
cpuinfo_transition_latency  scaling_driver

Code: Select all

~$ lsmod | grep phc
phc_intel               6629  1 
mperf                   1515  1 phc_intel
What can be wrong?

I will answer myself.
I fixed the problem by deleting everything related to phc (including kernel) and installing all once more. I don't know what was previously wrong because now I have done exactly same steps as before...
