Hi,
Some time ago, to fix heat problems on our panda boards which
building/validating GCC, I upgraded the kernel and activated the
thermal features: I switched to 3.7.2.
I used some of the instructions found in:
https://wiki.linaro.org/Resources/HowTo/KernelDeploy
The tests I performed afterwards look OK, but I have noticed that
there is no longer any
/dev/mmcblk0p1 so I am wondering how I will manage to upgrade next time?
What am I missing?
Thanks,
Christophe.
Hi Andrey,
Sorry for being late this time. Were waiting for Android tree to become

Hi Guys,
Below are hangout upstreams of Scheduler Internals by Vincent Guittot
done in LCA13.
We have got another version of this recording that is done by some
other cameras, but
its size was 30 GB and so hard to upstream. In case you need that
please contact me.
Day 1: http://www.youtube.com/watch?v=2yzelou80JE
Day 2: http://www.youtube.com/watch?v=fN11Lltx1nQ
Thanks to Naresh for arranging for hangouts.

This is to let you know that the migration of lists.linaro.org has been
successfully completed.
As per the email I sent on Wednesday, it may take some time for the new
address of the server to be seen by your computer. You can check this by
trying to connect to the web site:
http://lists.linaro.org/
If you are able to connect and you do not get an error, this means you are
connecting to the new server and you can send email to the lists.
If you experience any problems after the weekend and you find that you
still cannot connect to the server, please reply to this email to let us
know.
Regards
Philip
IT Services Manager

According to the TRM for TC2 the default value for that register is
0x33330c80, so adding the line "SCC: 0x400 0x33330c00" and incrementing
TOTALSCCS does the trick, and the A15's now report an icache size of 32.
We'll have to get everyone with a TC2 to make that change then?
As this is a TC2 issue, and not Linux related, shall we drop
linux-arm-kernel from all future replies to avoid the noise? I've added
linaro-dev to the cc list so this continues to get public visibility.

Postmortem and lessons learned for Linaro's release 2013.02
https://wiki.linaro.org/Cycles/1302/Release/Review
Highlights and Key Successes
============================
http://www.linaro.org/downloads/1302http://wiki.linaro.org/Cycles/1302/Release#Release_Information
The Linaro Engineering Group (LEG) released Linaro UEFI 2013.02 which
fixed several bugs targeting the Arndale boards. LEG also added ARM
support to libhugetlbfs, merged into next branch--package is available
from Linaro's Overlay PPA.
The Linaro Developer Platform team completed the CI bring up for the
Arndale board: Arndale image reports have been added to the LAVA
dashboard and daily tests are run on the board. The team has also
enabled UEFI support in the Arndale hardware pack.
The Linaro Toolchain Team released Linaro GCC 4.7-2013.02-01 based off
GCC 4.7.2+svn195745 and includes arm/aarch64-4.7-branch up to svn
revision 195716, support for Cortex-A7 backported from trunk. The
2013.02 Linaro Toolchain Binaries release were updated to latest
Linaro GCC 4.7 2013.02-01 which included upgrades for binutils to
v2.23.1, eglibc to v2.17 and the kernel header to v3.7.
Blueprints

Android 7 out of 11
Developer Platform 5 out of 9
Infrastructure 1 out of 4
Lava 4 out of 7
QA 2 out of 9
Total 19 out of 40
48% of high or essential priority blueprints scheduled for this cycle
