Last version of kernel-power is v53, see announce thread http://talk.maemo.org/showthread.php?t=94287

Thread about kernel-power has now a lot of post and now I missed a lot of them. I'm creating this new thread for kernel-power only for development discussion. So this is right place for discussion about patches, modification, adding new features, module, fixing bugs...

!!!Please do not write here post about user problems about download/installation...!!!
It should go here: http://talk.maemo.org/showthread.php?t=94287

Here are some info where to get source code, how to compile kernel, ...

Source code:
Project is hosted on Maemo Garage in git repository.
Project site: https://garage.maemo.org/projects/kernel-power/

Bugs/Patches:
Bugs and patches can be reported/sent in this thread, on project bug tracker, on IRC or on my email address.

Compiling:
0. Download source code from git repository (may contains unreleased code):

Code:

$ GIT_SSL_NO_VERIFY=1 git clone https://vcs.maemo.org/git/kernel-power
$ cd kernel-power
$ kernel-power-2.6.28/debian/rules get-orig-source
$ tar --strip-components=1 -C kernel-power-2.6.28 -xf kernel-power_2.6.28.orig.tar.gz kernel-2.6.28

0. Or download via apt (contains exact same last version):

Code:

$ apt-get source kernel-power

1. Compilation in scratchbox:

Code:

$ fakeroot apt-get install sdk-fiasco-gen
$ cd kernel-power-2.6.28
$ dpkg-buildpackage -b -rfakeroot

2. Compilation with madde:

Code:

$ cd kernel-power-2.6.28
$ patch -p2 -i debian/madde.patch
$ mad dpkg-buildpackage -b
$ patch -p2 -R -i debian/madde.patch

Do you have any changelog of the new kp49 build wrt the previous one?

Would you mind to build compcache/ramzswap module with stats enabled? (if not already done)
