• Supports as many cores as kernel--typically 4 or 8 (thanks to Iguleder)

• Gleans available modules and governors from active kernel. (thanks to Iguleder)

• Displays current core speeds, scaling driver and governor

• For ondemand governor, select frequency range and from 4 up_threshold modes:
95% Powersave, less responsive
80% Default
50% Balanced, more responsive
30% Performance, very responsive
(My personal preference is 50% with AC power, 80% with battery)

• Remove driver option
• Feedback / status panels
• Help dialog
• New icons
• Works from root or 'fido' user in Wary
• Activates during boot up
• Displays $DISTRO_NAME in title bar

Displays active cpufreq driver module and scaling governor, even if loaded by script in /etc/init.d, other pets or in rc.local.

Tested on Slacko 5.4.0.5, Lucid 5.25, Wary 5.1.1.53, Fatdog 64 611 and Lighthouse 64 6.00

Changelog
2013.03.02 1.1 Bugfixed pinstall.sh for Woof build, thanks to 01micko.
gtkdialog icon tweak.

wcpufreq--1.0 130210
Precise bugfix: Expand driver search to new kernel module locations.
More info on the first panel. Support Woof in pinstall.sh.

wcpufreq-0.8 110910
Updated for Fatdog 64-520; account for scaling drivers built-in to kernel instead of compiled modules.

wcpufreq-0.7 110508
Activate at boot up from /etc/init.d/wcpufreq instead of script in ~/Startup.
Removed /home/spot and /etc/skel directories from wcpufreq.
Updated for fido user compatibility in Wary.
Woof/Wary: earlier versions of wcpufreq sometimes failed to activate on reboot--fixed.

wcpufreq-0.6 110424
Bugfix: Jim1911 and taca0 reported that prior scaling module was removed after reboot or second run of wcpufreq. Removed mperf module from driver selection dialog and improved detection of current driver by scanning /proc/modules.

wcpufreq-0.4 101027
Name changed to wcpufreq. Account for /etc/init.d/start_cpu_freq (recent Woof script) when detecting driver. Display current core speeds. up_threshold selection for ondemand governor. Suggest to avoid using p4-clockmod driver. Advise if no acpi or BIOS was released before 2007. Updated help dialogs.

pcpufreq-0.3 Initial release 101023

Thanks for testing, Jim. Can you post your processor type (Menu | System | Hardinfo | Processor.) And the contents of any scripts in /root/Startup with 'cpu' in their name. It sounds like a scaling driver module is loading somewhere I haven't checked, or maybe our tool doesn't work with certain CPUs.
Thanks,
TazOC

Jim,
Disregard my previous post. I found a script, /etc/init.d/start_cpu_freq dated 3 June 2010 in Woof-based pups that I hadn't seen before. I will update my pet to account for that and do some testing.
Thanks,
TazOC

[Edit] Some Woof history on CPU Scaling in Barry's Blog. Jemimah wrote that p4-clockmod is not desirable for at least EeePCs.

wcpufreq-0.4 released

Should always detect current driver now, or work from scratch. Please test.

Name changed to wcpufreq.
Accounts for /etc/init.d/start_cpu_freq (recent Woof script) when detecting driver.
Display current core speeds.
'up_threshold' selection for ondemand governor.
Suggest to avoid using p4-clockmod driver.
Advise if no acpi or BIOS was released before 2007.
Updated help dialogs.

Thanks,
TazOC

Hi TazOC,

Just happened to see this while testing the new Wary 0.9.4. Installed it and it seems to be working fine.

Incidently, printing with LibreOffice and other applications works fine on this Wary.

Cheers,
Jim

Hi Jim,
Thanks for testing. Very Happy

You have 8 cores? That is sweet!

Please PM me preferred user/passwd if you'd like to post the LibreOffice SFS at lhpup.org; or if its already up somewhere.
Thanks,
TazOC

Hi TazOC,

Sorry that it's taken so long to respond. This is output from Lighthouse 5.00 F, not good.

Iguleder · Posted: Sun 31 Oct 2010, 13:16 Post subject:

The kernel has no Hyperthreading support, that means you see only half of the number of cores. I know the Lupu kernel (which is also the Lighthouse kernel) has no Hyperthreading, that's one of the reasons why I chose to go for our own kernel in Squeeze Wink

That kernel also lacks rfkill and other important things ... but that's just my opinion Rolling Eyes

Thanks, Jim. Yeah, Iguleder's on to something there. I was just going to say the kernel in LHP 2.6.33.2 (from Quirky 1.2 I think) probably wasn't compiled to support 8 cores.
This should clarify:

I found these entries in Lighthouse 5.00 F
/etc/modules/DOTconfig-K2.6.33.2-5APR2010-SMP-TICKLESS:

CONFIG_X86_HT=y
CONFIG_NR_CPUS=4

[Edit:]
FD64-500: /etc/modules/2.6.34.config

CONFIG_X86_HT=y
CONFIG_NR_CPUS=8

Look at the kernel configuration. Here's an example from the latest Squeeze kernel. It has SMP, Hyperthreading and support for up to 8 cores, since most people don't need more than that and also because more than 8 cores need BIGSMP which results in extra size, while each core doesn't add much when it's up to 8 cores.
