Puppy Linux Discussion Forum

[tempestuous]

I'm close to releasing an ACPI/hotkeys package for ASUS Eee's with Puppy 4.3.
Forum member jakfish is currently testing with one of the Celeron-powered Eee models, but we can't test CPU control of Atom CPU's.

Are there any Eee-Atom owners who are prepared to do some testing?
Here's what I need:

In Puppy 4.3 with the 2.6.30.5 kernel, first run "lsmod" to check that the new "eeepc-laptop" module has automatically loaded.
If it's listed, great. If not, load it manually -

Sorry. The command should be -

[01micko]

Hi tempestuous

I have the eee 701sd

Here's the output from 'lsmod'

[01micko]

I run that command and I get

[hokal]

That's what I get on my eeepc901

# cat /sys/devices/platform/eeepc/cpufv
768

does it ring a bell ?? I have no idea!

[aarf]

and the answer is:
53

OK, I just did some more Googling, and it appears that the values I listed for setting the mode were correct (0/1/2)
but the values returned from the cpufv control file are different -

770 powersave
769 normal
768 performance

I have corrected the first post.

Can everyone please try changing the mode.

[01micko]

Hello tempestuous

All commands work as expected on the 701sd.

It is not smart enough to change mode when the plug is pulled and run on battery, even in performance mode.

There are no apparent heat issues, running now at 49°C.
Cheers

[tempestuous]

01micko, the 701SD has the Celeron processor, right?
So you're saying that the Celeron will successfully change CPU modes using this process?
This is contrary to what I have read on the web. I wonder if the mode is truly changing? Can you detect any difference in the modes ... does the powersave mode actually feel less responsive?

[01micko]

Hi tempestuous

Yes it is the Celeron. No it doesn't feel much different. I just tested powersaving compared to performance and there really wasn't any perceivable difference.

Cheers

[mawebb88]

Ok these are my results on my Atom (EeePC901)

Initially on battery

cat /sys/devices/platform/eeepc/cpufv = 769

After echo 2 > /sys/devices/platform/eeepc/cpufv

770

1 gives 769 and after 0 gives 768

But in all cases of issuing echo x > /sys/devices/platform/eeepc/cpufv

I had to CTL/C in rxvt to get the prompt back.

Ok, maybe we can snag some more testers with this little gui I knocked up such that you can change the status of your performance without going near the command line.
You will see the status in a splash screen about 5 seconds after clicking your choice. Start it from Menu>>System>>Eee Performance.

Warning: Only for eee pcs. Use at own risk. I have tested it but only on a Celeron, no unusual behaviour. If you Atom guys experience your cpu getting warm or something unusual in 'Top' shut down and uninstall the pet.
Do not use on Eeepc900 with 900 Celeron, freezes cursor as reported by rhadon.

Cheers and many thanks tempestuous for your work with eee pcs.

Update: Version 0.1.1 shows a tool tip. eg:"Powersave should show a value of '770'". Only so we know what we are doing.

Of course you should familiarise yourself with the commands in the main post so you know what is happening.
