Undervolting (not underclocking) Possible in Puppy? |
|
I had a look at linux-phc ( http://linux-phc.org/ ), but couldn't find anything for the 2.6.39 kernel in pemasu's dpup exprimo 5.X.14-SCSI.
Looks like tricky stuff, but perhaps more effective than cpu frequency and scaling in lowering cpu temperatures.

Hi jakfish
I've no experience of this myself but you may find one of the following threads useful-
How to keep your cpu cool and your fan quiet
http://www.murga-linux.com/puppy/viewtopic.php?t=28443
How to adjust P states (freq and power) in AMD processors
http://www.murga-linux.com/puppy/viewtopic.php?t=64414
more information about your hardware could be useful.

Hi, darkcity,
I'm using an intel/atom processor so the amd won't work, I don't think.
I have looked at the scaling and frequency threads, but that appears to be different than actual undervolting.
Thanks for your post,
Jake

dpup exprimo is debian based so you should be able to use debs
there is a guide for ubuntu here-
http://openmindedbrain.info/09/05/2010/undervolting-in-ubuntu-10-04-lucid-lts/
In Puppy you don't need the sudo at the start of lines.
Also, there is no apt-get
| Quote: | 1. As we are going to use a custom kernel, we need to add the linux-phc PPA repository, so just open a terminal and execute:
| Code: | 1 $ sudo add-apt-repository ppa:linux-phc/ppa
2 $ sudo apt-get update |
Basically they provide the same kernel as the Ubuntu one but with the patch that is capable for Undervolting.
2. Next we need to install the phc kernel, with headers:
| Code: | | 1 $ sudo apt-get install linux-generic-phc linux-headers-generic-phc |
|
this section is just about loading-
linux-generic-phc
linux-headers-generic-phc
these can be downloaded as deb and installed, for example from
https://launchpad.net/~linux-phc/+archive/testing/+sourcepub/2445965/+listing-archive-extra
l
2.6.38 was the closest kernel I could find.

Hi, darkcity,
I'm new to this cross-platform stuff. In that launchpad link you included, do I need to install all its listed .deb files?
Or just the two you cited:
linux-generic-phc
linux-headers-generic-phc
Again, I appreciate your help with this,
Jake

Hi jakfish
according to the guide you just need
linux-generic-phc
linux-headers-generic-phc
if it was ubuntu
1 $ sudo add-apt-repository ppa:linux-phc/ppa
2 $ sudo apt-get update
line 1 adds ppa:linux-phc/ppa repository (as the require files aren't in the standard repositories)
so apt-get will be available to find linux-generic-phc, linux-headers-generic-phc.
I can't promise it will work, just an idea

No, that didn't work; it would've been too easy None of the necessary .ko's appeared in the kernel module directory.
It appears that the liquorix kernel has linux--phc built-in:
http://liquorix.net/
It'd be interesting to run the liquorix kernel in dpup exprimo, but apt-get seems necessary for its installation, and that doesn't appear to be up and running on puppy.

shame that didn't work.
apt-get isn't part of Puppy we have the PPM instead
however all apt-get does is load files into the linux rootfs, so as long as you can download the files you can do it manually.
However, Pussy linux closer to debian, it has apt-get and is 100% compatible, see
http://www.murga-linux.com/puppy/viewtopic.php?t=69475
also see,

Thanks for those links. Tried to do an unholy union between pussy and liquorix, but the instructions I'm finding are calling for files that no longer exist on liquorix via apt-get
As for making my own kernel, this seems to have every conceivable debian file for a custom:
http://liquorix.net/debian/
I understand that I don't need anything AMD, but can't figure out which and where to put the others.
This is way above my pay grade, so feel free to bow out at any time You've already been a huge amount of help.
Jake

unholy unions are the best,
what files do you need via apt-get?
have you ensured the necessary repositories have been added to apt-get?
