Hi,

this updated phc-intel package includes phc-intel 0.3.2 and 0.4.0 (test release)
for stable and longterm kernel since version 2.6.27

key changes:
* Fix syntax error in makefile, thanks acuchimoja for the report.
* In kernel 3.9 some unrelated code was included so some hunks had to be adjusted to new offsets to apply the patch without warnings.
see README.1st for a quick intro

have fun and be cool
Dirk

Please correct a bug in phctool, I already written an alternative version. In kernels 2.6.36 or higher you have no more /proc/acpi/processor/CPU./info.

No window opens, if run in terminal you get:

Code:

Traceback (most recent call last):
File "./phctool.py", line 468, in <module>
app=appgui()
File "./phctool.py", line 81, in __init__
self.cpuinfo=cpuinfo.cpuinfo() ##functions to gather CPU informations
File "inc/libs/cpuinfo.py", line 12, in __init__
self._get_acpi_cpus() ##get ACPI-supported CPUs
File "inc/libs/cpuinfo.py", line 43, in _get_acpi_cpus
self.data[cpunr]['acpi']['exist']=False
UnboundLocalError: local variable 'cpunr' referenced before assignment

Here is a newer version of the buggy function. Please replace it!

Of course a fallback on old behaviour has been implemented, so no worry.

Cheers!

[EDIT]

This is fine for 3.6.36 and 2.6.37 kernels, but 2.6.38 has /proc/acpi/processor no more, I'm working on a proper change in throttling.py

[EDIT2]

Found a temporary solution, modifying cpuinfo.py but my cpu is a core 2 duo, so no throttling is available... need someone to properly edit throttling.py!

I'm posting it here and opening a newer thread

Cheers

Thanks Dirk! Everything seems to work great on the latest 2.6.38

Thanks, this package is great, I am looking forward to see how dkms behaves with new kernel updates

I think this advanced packaging should be provided also for the official release thread, I would have hardly found this without your suggestion.

Thank you very much!!! :!:

Works fine on Kubuntu 11.04 with 2.6.38.

Hi Dirk,

thank you very much for this package! It provides exactly what I was looking out for a long time, DKMS and DEB, grate!

However, I have some troubles. The problem: I can whether load the phc-intel module nor can I unload the acpi-cpufreq module.

I tried this on a Ubuntu 11.10 installation. As Kernel I am using the modified generic-phc from ppa:linux-phc/testing.
uname -r

Code:

3.0.0-13-generic-phc

grep -i acpi_cpufreq /boot/config-3.0.0-13-generic-phc

Code:

CONFIG_X86_ACPI_CPUFREQ=m

So, I downloaded the above file and created a DEB:
make dkms_mkdeb

Code:

                 ./.dkms//usr/src//phc-intel-0.3.2

 ./phc-intel-dkms_0.3.2_all.deb 

And installed the resulting DEB.

So far, so good. However, when trying to unload acpi-cpufreq module:
sudo rmmod acpi_cpufreq

Code:

ERROR: Module acpi_cpufreq is in use

sudo rmmod -f acpi_cpufreq

Code:

ERROR: Removing 'acpi_cpufreq': Device or resource busy

Sure, under this circumstances I can not load phc-intel module:
sudo modprobe -v phc-intel

Code:

insmod /lib/modules/3.0.0-13-generic-phc/updates/dkms/phc-intel.ko 
FATAL: Error inserting phc_intel (/lib/modules/3.0.0-13-generic-phc/updates/dkms/phc-intel.ko): Device or resource busy 

Any suggestions? I have no ideas what to do now.

Best, Stefan

If some mod passes here I suggest moving this post and the one before in the Help folder.

Talking about your issue...
First of all you don't want to delete that module, but to unload it. So you shoud not use rmmod but:

Code:

sudo modprobe -r acpi-cpufreq

Anyway it looks strange, sometimes when people complained about such behaviour a reboot did the job, but also, be sure to use the right kernel with

Code:

uname -a

then take a look at the loaded modules with:

Code:

sudo lsmod

Cheers

Sorry for using the wrong forum - my fault. May be one of the mods could be so kind and move this to where ever it is appropriate.

This is a really strange behavior. The kernel config shows that the 'acpi_cpufreq' is build as module and also this kernel is loaded.

Code:

uname -a
Linux WMS005 3.0.0-13-generic-phc #22~phc1-Ubuntu SMP Tue Nov 22 23:31:01 UTC 2011 i686 i686 i386 GNU/Linu

But I can not unload or delete the acpi_cpufreq module.

Code:

sudo modprobe -r acpi-cpufreq
FATAL: Module acpi_cpufreq is in use. 

I also tried to blacklist this module in /etc/modprobe.d/blacklist.conf

Code:

blacklist acpi_cpufreq

Also the initramfs is up to date. Unfortunately, without success, the module is loaded anyways.

Code:

lsmod |grep cpufreq
cpufreq_stats          13172  0 
acpi_cpufreq           13203  1 
mperf                  12603  1 acpi_cpufreq 

How could this be, it is blacklisted.

Could it be, that the kernel config file is wrong and acpi_cpufreq isn't compiled as module?

Unfortunately, my post isn't moved to the 'help-forum'. Despite posting my issue not at a fully appropriate place I want to present a workaround.

Blacklisting both modules acpi_cpufreq and cpufreq_stats and additionally putting phc-intel to /etc/modules solves the problem.

Cheers, Stefan
