Like some others i'm having the problem of no phc_* files showing up in /sys/devices/system/cpu/cpu*/cpufreq.
Code: Select all
$ ls /sys/devices/system/cpu/cpu0/cpufreq
affected_cpus ondemand scaling_governor
cpb 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 stats
cpuinfo_transition_latency scaling_driver
As denoted in the subject the cpu is an Athlon X2 QL-66.
I've installed (via apt-get install linux-generic-phc linux-headers-generic-phc) and booted the phc-kernel:
Code: Select all
$ uname -a
Linux violet-sunshine 2.6.31-21-generic-phc #59~phc0-Ubuntu SMP Fri Apr 30 13:12:51 UTC 2010 x86_64 GNU/Linux
Code: Select all
$ lsmod | grep phc
phc_k8 23600 0
mperf 2308 1 phc_k8
dmesg says:
