Saving power in Porteus
Posted: 29 Jun 2011, 15:16
Hi all,
So, I read a thread over at linuxquestions.org, which inspired me to start on some research and a little project. You can read that thread here: http://www.linuxquestions.org/questions ... ost4399191
Over the next few days, I'm going to be searching for ways to reduce my power consumption and extend my battery life. More battery life for Ahau means more docs for Porteus
Speaking of docs, I plan on making a "porteus tweaks' doc out of my experience. I think I'll be recompiling the kernel as well, so that means I'll be trying out and sprucing up the kernel compile HOWTO, which has been the source of confusion for a couple folks (I believe, starting with the fact that it doesn't mention modprobing your current configs ).
I'll post some links and tips here as I go along. If any of you have ideas to add, let me know. If I'm successful in compiling a kernel that provides additional power savings, I'll post it for others to download and test (and maybe some suggestions will make it into the kernel for 1.1).
Links so far:
http://www.lesswatts.org/projects/powertop/
http://www.gentoo.org/doc/en/power-management-guide.xml
http://www.linuxfordevices.com/c/a/News ... orkaround/
That link has info on a regression specific to kernel 2.6.38, with the "pcie_aspm=force" kernel parameter fix
http://www.thinkwiki.org/wiki/How_to_re ... onsumption
I'm going to compile powertop against the Porteus Kernel to see if I can get better recommendations out of it. If I get that working well, I'll post a module for that as well.
Cheers!
