Golly, is that the dual SD card you and David from tincantools have been working on?

LAVA tests in fast models have started!

by Zygmunt Krynicki

Hey folks. Initial batch of LAVA tests in fast models are now running in the Linaro validation lab. This initial run is designed to see how behaves in practice and to check for omissions occurring away from my computer. The branch that I've deployed is lp:~zkrynicki/lava-core/demo-3 (it depends on unreleased json-document tree from github if you want to try it out, there are instructions in the tree). We've got the licensing server setup for production usage and started a (arguably dummy) stream lava-test test based on hwpack_linaro-vexpressdt-rtsm_20120511-22_armhf_supported.tar.gz and linaro-precise-developer-20120426-86.tar.gz which is the combination I was using locally. Over the next few days we'll be working on improving the process so that we can start accepting more realistic tests. Initially do expect high failure rate due to imperfections in the technology, configuration issues, etc. The plan is to quickly move to practical use cases. So far I'm aware of the switcher tests that the QA team is using, and the kvm tests but I have not checked either, in practice, on a fast model yet. My question to you, is to give me pointers (ideally as simple, practical instructions that show it works) for things that you want to run. I'm pretty ignorant about Android side of the story so any message from our android team would be appreciated. Please note that iteraction cycle is very slow. It takes 10+ hours to do trivial things (doing apt-get update, installing a few packages, compiling trivial program and getting it to run for a short moment). Please don't ask us to run monkey for you as we'll be wasting time at this point. My goal is to understand what's missing and to estimate how long given tests typically takes so that we can compare how our infrastructure compares to your needs. Many thanks Zygmunt Krynicki -- Zygmunt Krynicki Linaro Validation Team

This new driver doesn't do anything yet, BTW, it's just a load of debug code.

Andy, you can just remove my patches from the tree if you like. I can send you a fresh set of patches that apply cleanly over the STM topic when I have something else for you to test. As mentioned in the previous mail, my current set of patches just do some debugging stuff and don't really constitute a "driver" for ARM's STM. > > > The Framework driver is not using /sys in any way, just /debugfs, so >> anything with /sys was added by Ryan. >> > > You're quite right, if I looked a little further along I would have seen > it's /sys/kernel/debugfs.

[PATCH 0/2] ARM: S3C64xx: cpuidle cleanups

by Daniel Lezcano

These couple of patches use the new cpuidle core api to refactor some part of the code. The first one declares the states directly in the driver declaration and the second one use the timekeeping flag to let the cpuidle core to compute the idle time. I don't have this board, I was not able to test these patches.

Making ARM multiplatform kernels DT-only?

by Arnd Bergmann

Hi everyone, I've been discussing multiplatform kernels with a few people recently, and we will have a lot of discussion sessions about this at Linaro Connect in Hong Kong. One question that came up repeatedly is whether we should support all possible board files for each platform in a multiplatform kernel, or just the ones that are already using DT probing. I would like to get a quick poll of opinions on that and I've tried to put those people on Cc that would be most impacted by this, i.e. the maintainers for platforms that have both DT and non-DT board files at the moment. My feeling is that we should just mandate DT booting for multiplatform kernels, because it significantly reduces the combinatorial space at compile time, avoids a lot of legacy board files that we cannot test anyway, reduces the total kernel size and gives an incentive for people to move forward to DT with their existing boards. The counterargument is that we won't be able to support all the boards we currently do when the user switches on multiplatform, but I think that is acceptable. Note that I would still want to allow users to build platforms separately in order to enable the ATAG style board files, even for platforms that are not multiplatform capable. Other opinions? Arnd

What is right git tree/ branch for imx28/evk device tree work?

by Subodh Nijsure

Sounds like a very basic question, I would like to test some of the recent patches related to mx28 for freescale EVK board. ( Some thing like - https://lkml.org/lkml/2012/3/13/176 ) Is there specific branch one should be looking for in git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc.git? Or these changes are being staged some place other than arm-soc.git? Thanks for the help -Subodh P.S. I posting it linaro mailing list 'cause lot of this device-tree patches seem to be coming from folks with at-linaro.org email addresses.
