vcpufreq development thread

[nightflier]

Got the package. Will upload to my contrib.

Installed fine. Running vcpufreq.gambas displays the screen, however the current frequency is not being displayed on the right hand side for some reason.

I get the same thing. Additionally, the slack-desc still refers to vcpufreq-load rather than vcpufreq-loader.gambas.

Can you guys post a screenshot, plus some machine specs related to the CPUs? Also, run it from a console and see if there are any warnings or errors. I will fix the slack-desc, thanks for the heads-up.


EDIT: Also please post the Gambas version installed.

On my laptop:

--------------------------------------------------------------------------------
On my desktop it works fine. I do get the freq readout.  Some vitals about it:
2.6.31.8 #1 SMP PREEMPT Mon Dec 14 19:28:23 MST 2009 i686 Intel(R) Core(TM)2 Duo CPU     E8500  @ 3.16GHz GenuineIntel GNU/Linux
Same gambas2-runtime as above.
vcpufreq driver acpi-cpufreq.

---------------------------------------------------------------------------------
Upgraded to gambas2-runtime-2.15.0-i586-1vl60 (skipped the mysql and postgresql deps, though). No change.

This is on my notebook as well....

Screenshot is from the cli. No errors on running vcpufreq.gambas.

Here's a fix for the empty grid with single CPU/core, which was a bug. Please retired1af also test it on your AMD Turion(tm) 64 X2 Mobile just in case. If it doesn't fix the latter, we would have to check if there are differences in the kernel cpufreq interfaces between AMD and INTEL, something I really hope does not happen...

Changelog:

Code:

2010-07-05   <joe1962@users.berlios.de>

* Released 2.4.1

2010-07-05   <joe1962@users.berlios.de>

* BUG: CPUFreq_Refresh() did not update gridview for single CPU/core

[retired1af]

Pulls in CPU0 but not CPU1.

[nightflier]

2.4.1 fixed it for my single core Celeron. 

[Joe1962]

Pulls in CPU0 but not CPU1.

I think I understand now. There is a check in vcpufreq for "affected CPUs"  when setting the freq. on CPU0. This means any CPUs which are linked to CPU0 and whose freq. changes with it. I had only seen this so far on hyperthreading CPUs, where there are no real separate CPUs or cores, but I guess your Turion also works like that, even though the X2 is supposed to be a true dual-core. In cases like this, vcpufreq only sets CPU0, instead of looping through all the CPUs/cores to set them. I had initially figured why show the rest of the values in the grid when they simply cannot have a different freq. Now I think it should just show them all regardless. I should have that done tomorrow...

[Joe1962]

And here it is as promised...

* Released 2.4.2

2010-07-06   <joe1962@users.berlios.de>

* BUG: CPUFreq_Refresh() only updated gridview for CPU0 when others "affected"

Downloaded, installed and working great!

[nightflier]

I am not at home with access to contrib for a week. If need be I'll help move package when I return.

[Joe1962]

Thanks, guys!

[nightflier]

Got a break from work.  Posting package.
