Hi folks,
As a follow-up to my work in LEG on assembly scanning and optimisation
for AArch64, we're considering applying as a mentoring organisation
for the Google Summer of Code [1] this year. There's quite a lot of
code out there that may benefit from porting (whether for support of
AArch64 or for better performance) and I think we could usefully get
some students involved to help with this. I'm planning on doing the
bureacracy for the SoC application in the next few days.
So, the reason why I'm posting about that here: is anybody else
interested in joining in? Are there any other projects in/around
Linaro where:
a) a student could do some useful work;
b) we have somebody prepared to act as a mentor
? If so, please let me know. The more ideas we can suggest for summer
projects like this, the more likely we are to be accepted as a
mentoring organisation by Google.

Hi John,
I have been struggling since some time "who creates source directory
in my kernel tree"?
And i thought to clean up the mess today and found running
merge_config.sh creates
it.. And it isn't cleaned up even by running make mrproper...
PS: I am not using O=../ option.

Hi,
I'm trying to cross build some packages for ubuntu quantal following this wiki:
https://wiki.linaro.org/Platform/DevPlatform/CrossCompile/UsingXdeb
we would like to be able to build packages like gstreamer.
today, I'm able to compile busybox and grep but no gstreamer or gstreamer plugins
Here is my HowTo:
sudo su
debootstrap quantal m-xdeb
chmod 777 m-xdeb/etc/apt/sources.list
vi m-xdeb/etc/apt/sources.list
deb [arch=armhf] http://ports.ubuntu.com/ quantal main universe
deb-src http://ports.ubuntu.com/ quantal main universe
deb http://archive.ubuntu.com/ubuntu quantal main universe
sudo chroot m-xdeb
mount -t proc proc /proc
mount -t devpts none /dev/pts
export LC_ALL=C
adduser build
adduser build sudo
apt-get update
apt-get install -y xdeb gcc-arm-linux-gnueabihf g++-arm-linux-gnueabihf
dpkg --add-architecture armhf
exit
sudo chroot m-xdeb su - build
export LC_ALL=C
here are the results:
xdeb -a armhf --only-explicit --no-lintian --apt-source grep
OK
xdeb -a armhf --no-lintian --apt-source gstreamer1.0
Fails:

I have tried to use repo quantal-updates with also bad result.
I have tried to use lower level tools, but I did not found a way to install cross build-deps
apt-get build-dep -aarmhf ... always fails like this:

I guess I missed something... apt.conf ? sources.list... ?
Can somebody help me ?

I have been observing this system hang when we enable LPAE on 3.9 based
llct, though the issue is not present with vanilla 3.9-rc kernel. Would
update later after I debug further.
Riku,
How much essential is it to enable LPAE support for KVM?
