Hi all,
In connection with the recent discussion with the tools guys about how
to document the availability of binary toolchains, I wonder whether
www.linaro.org really links to the best pages on launchpad, the wiki
etc.
Keeping these in sync and coherently structured is a maintenance
requirement, and we can't expect to eliminate that.
But I'm wondering whether we have some way to track:
a) HTTP requests with no Referrer
b) Pages reached directly from Google or some other search facility
(such as the wiki or launchpad search)
Pages reached in these ways indicate where developers are using a
shortcut and visiting pages directly (I know I do this) or where the
page is at least sufficiently hard to find that Google or the wiki
search is more efficient (I know I do this too). If we could come up
with a list of such pages and frequency of visits, this might give us
some interesting information about what we really should be linking to
from the main website. It might also help to flag up drift, where
activity hotspots move away from the pages accessible from the website
over time.
Cheers
---Dave

Hi, John:
I have one question about the origin/dev/linaro.android branch
right now for beagleboard xM.
After tried, I still can not see the terminal log after the "Virtual
kernel memory layout" message with EARLY_PRINTK enabled., even printk
messages in omap3_beagle_init() can not be seen.
I see With 2.6.36/37+: the console should be changed to
'ttyO2,115200n8' in u-boot. but the problem still exists for me.
Could you give some clue for me how to solve this?
Thanks.
Regards,
-Jeremy
Hi,
I have started to use the new cpuidle tracepoint and created a plugin
for pytimechart.
I'm not sure if it's the right way to add this cpuidle trace format
update but it's the less intrusive one.
I also have a plugin for new cpu_hotplug trace points but i'm waiting
for trace approval before sending it
Vincent
Subject: [PATCH 1/1] cpuidle: new plugin
new tracepoints are available for cpuidle

1.7.1
Nicolas,
With the patch:
ARM: 6746/1: remove the 4x expansion presumption while decompressing the kernel
I get a build error. This is when building my packaged kernel with
debuild. Notice the stat failure __after__ the "Kernel:
arch/arm/boot/Image is ready message". Then later ld fails because of
the stat failure.
GEN .version
CHK include/generated/compile.h
LD .tmp_vmlinux1
KSYM .tmp_kallsyms1.S
AS .tmp_kallsyms1.o
LD .tmp_vmlinux2

OBJCOPY arch/arm/boot/Image
Kernel: arch/arm/boot/Image is ready
stat: cannot stat `arch/arm/boot/compressed/../Image': No such file or directory
AS arch/arm/boot/compressed/head.o
GZIP arch/arm/boot/compressed/piggy.gzip

AS arch/arm/boot/compressed/piggy.gzip.o
LD arch/arm/boot/compressed/vmlinux
arm-linux-gnueabi-ld:--defsym _image_size=: syntax error
The odd thing is that after the failure I can look in the directory
and Image is there so its like it some kind of race?
For the moment I am working around this be reverting this patch but
obviously thats not a real solution.
Thanks,
John

Hi,
Just tested the imx51 Thumb-2 kernel on efikamx here -- it boots fine,
but we only went as far as the initramfs.
Is anyone currently relying on CONFIG_LATENCYTOP? If so, we should
investigate what the incompatibility is...
Cheers
---Dave
