2012-09-19 Thread srinivas reddy

Hi ,


  I am using saberlite EVK board and try to boot form SD card.
  In the below link it is metioned that we  need to be reflash board with a
small SD card loader to support boot from SD card.

https://wiki.linaro.org/Boards/MX6QSabreLite.

I did as per the link but it did't work for me. I even does not have MFG
tool to flash NOR.
Now my board doesnt have any image it seem. it is not booting and serial
console, i am not seeing any messages.

Please let me where i can get the MFG tool for saberlite and pre-build
image to flash my board again.

please help. i am deadly need of this..

big.LITTLE MP status Sep 18, 2012

2012-09-19 Thread David Zinman

https://wiki.linaro.org/projects/big.LITTLE.MP

Blueprint updates:

https://blueprints.launchpad.net/linaro-qa/+spec/task-placement-testing
 * smoke test is completed for cyclictest on Android.
 * cpu and thread features of sysbench required for scheduler testing
currently.
   * Android port supports those two features
 * sysbench, cyclictests have been delivered from the Android team.
 * cyclictest: dropped realtime clock feature in Android, libnuma
support removed from Android
 * ftrace raw data mode vs. txt mode: kernel shark only supports raw data mode.
 * By using sysbench and cyclictests we can create below listed loads
and time interval of running. while running these tests we need to
identify mechanism to instrument the kernel to identify and print, the
cluster number and core number, duration on test on each core. this
instrumentation has been planned at project level. so need to
communicate with development team and identify the best tools to trace
cpu, threads and time.


Roadmap Cards

Technical steering committee are currently reviewing the big.LITTLE MP
roadmap cards:

Could you try to run as followings ?

It should show APs. If not, it seems to be related to kernel drivers &

I believe that the pre-built RTSM binaries are integrated simulation
builds (i.e., like isim_system).  So the required command-line for
the isim_system binary built by the fast models package should be
similar to the examples we document for launching the RTSM binaries.

Cheers

[ANNOUNCE] Requesting work for the LAVA Lab

2012-09-19 Thread David Zinman

In an effort to structure the demands on the LAVA lab as Linaro
continues to grow and requests become more frequent, the LAVA team has
put in place a process for requesting work in the LAVA lab.

More platforms and devices are being added to the LAVA lab and the
demands on the LAVA team are growing. With this process we hope to be
able to accommodate all work requests as quickly as possible.

Please see
  https://wiki.linaro.org/Platform/LAVA/DevOps/LavaLabProcess

This is a work in progress and we invite all to comment.

This is not the case.  pm_genpd_attach_cpuidle() and
pm_genpd_detach_cpuidle() use them.

Please be more careful.

I just moved the condition out from the function and called it when the
condition is true.

if (!drv->power_specified)
set_power_states(drv);


But please, drop this patch too. I noticed there is an overlap with the
next patch I have in my series but not published.

Accidentally I removed "cpuidle_curr_driver = drv;"

Sorry for the inconvenience. Time for me to go to bed :)

There is no such prebuilt binary in my installation...
However I find the isim_system is similar to the model_shell,
with the same input I set to model_shell, it could launch the simulation
finally.

Still curious to know why model_shell don't work.

Here is another issue, although the simulation is ok for running A15x1,
but when I am trying to run the A15x4_A7x4, the simulation cannot be
launched up,
with the same configuration I could run at the 32bit machine.

The screen snap shot could be found at:
https://lh4.googleusercontent.com/-M8G9kBQztNI/UFqGMGqetNI/ACg/_1JGgppMhU4/s768/a15x4_a7x4.jpg

And the launch command I am using:
./isim_system  -a coretile.cluster0.*=boot-wrapper/linux-system-semi.axf -a
coretile.cluster1.*=boot-wrapper/linux-system-semi.axf -f params
Where the params is a file, containing:
motherboard.smsc_91c111.enabled=1
motherboard.hostbridge.userNetworking=1
