Hello there,
Last week we ran a series of open sessions as part of an
experimental Virtual Linaro Connect schedule; the blog post announcing
it is at:
http://www.linaro.org/linaro-blog/2012/08/07/linaro-announces-virtual-conne…
We ran all the sessions successfully over a combination of Google
Hangouts, IRC and Etherpad, and the videos are now all available for
your review and comments at:
http://www.youtube.com/channel/UCIVqQKxCyQLJS6xvSmfndLA?feature=guideo
If there anything on the menu that interests you, it's worth taking a
look at the sessions. The minutes linked to from the video pages are
also a good trove of information and can be used to follow the dialogue
which is sometimes a bit tricky.
We're considering running a wider Virtual Connect now that this one has
concluded successfully; I'd love to hear your feedback on how it went
and what you'd like to see us do differently for future events. Thanks!

Linaro.org: Open Source Software for ARM SoCs
The following 2 patches add driver for S5K4ECGX sensor with embedded ISP SoC,
and minor v4l2 control API enhancement. S5K4ECGX is 5M CMOS Image sensor from Samsung
Changes since v2:
- added GPIO (reset/stby) and regulators
- updated I2C read/write, based on s5k6aa datasheet
- fixed set_fmt errors
- reduced register tables a bit
- removed vmalloc
Changes since v1:
- fixed s_stream(0) when it called twice
- changed mutex_X position to be used when strictly necessary
- add additional s_power(0) in case that error happens
- update more accurate debugging statements
- remove dummy else
Sangwook Lee (2):
v4l: Add factory register values form S5K4ECGX sensor
v4l: Add v4l2 subdev driver for S5K4ECGX sensor

Hi there. I'm seeing a huge improvement in the SPEC floating point
benchmarks between a hacked Ubuntu Precise 3.2.14 kernel and Linus
3.5. Does anyone know why off the top of their head?
I see the same on a PandaBoard and PandaBoard ES. In both cases the
CPU is locked to 1 GHz and other power management features are
disabled.

I've seen questions in the past about how to make quick changes to a
uInitrd file. I hit the need to make a few changes today, and wrote a
quick script others might find useful:
http://people.linaro.org/~doanac/uinitrd.py
Basically it extracts things to a temp directory, drops you into a shell
where you can make changes, and then packages everything back up when
you exit the shell.
YMMV

Hi Andrey
Can you include a new topic to linux-linaro which contains device-tree
files for ARM's fast models? This branch is tracking-armlt-rtsm [1] in
the ARM LT working tree.
Thanks
For those interested...
These device-trees enable the the current Linaro vexpress kernel to boot
on fast-models when used with the boot-wrapper at [2], this includes
having a working display. However, on the big.LITLE models the A7 cores
don't start, giving "Failed to boot -38".

Cross-compiling is tricky because perf requires a lot of libraries.
I do it natively, using Ubuntu developer image. Also note that
perf can't be compiled outside of the kernel source tree,
so you should copy the full tree to your target. Yes, this is ugly.

Hi,
While executing reboot call on my ARMv7 board, the system hangs during
cpu_proc_fin() call.
Commenting out this line of code, the reboot works properly.

ENDPROC(cpu_v7_proc_fin)
is it a CPU_V7 specific issue?
Please provide your valuable input to fix the issue.
Any hint also..will help me in debugging further in this issue.
I have seen above fix in one of the linaro mailing list.

koteswararao.
