AMD Athlon X2 QL-66 no phc_files (karmic)

[hummlbach]

Hello Everybody!

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

Mostly the problem with this seemed to be unsupported cpu - but in my case I think the cpu is supported...?!
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

and built (make dkms_install ...) and loaded the phc_k8 module (0.4.3):

Code: Select all

$ lsmod | grep phc
phc_k8                 23600  0 
mperf                   2308  1 phc_k8

(Should I post the hole lsmod output? are there some modules that may conflict with the phc_k8 module?)
dmesg says:

Any ideas?
Thank you very much.

AMD processors with PStates (family 10h and 11h) are not yet supported, but I'm planning to release an alpha version (probably: v0.4.4a1) soon that supports lowering the voltages via phc_vids for these processors. Frequency changing will not yet be supported, that would require a completely new driver and will take a lot more time...

Oh... Okay - then I'm looking forward to the alpha-release.
Thank you very much for your efforts!

FWIW, I've uploaded an alpha2 release in Test-Releases that supports K10 processors (Phenom/Turion II, AMD II, etcetera).
