Hey If you try latest daily hwpacks + latest linaro-image-tools (0.4.4 or bzr) you should be getting Device Tree aware images for boards which support it (mostly i.MX51 and OMAP ATM). Feedback and bug reports welcome! Cheers, -- Loïc Minier

Automated kernel testing.

by Chris Ball

Hi Linaro folks, I'd like to set up an automated testing environment to help me maintain the MMC subsystem: just a few boards of different architectures booting each day's linux-next and running basic performance and integrity tests without any manual intervention involved. I've got access to remote power switches, so I think it'll be pretty easy to get running. I was thinking that this will probably find generic kernel bugs as they appear in linux-next, and was wondering whether Linaro has any interest in such testing -- if so, do you have any preferred software to use for it, or any resources I should take a look at to avoid duplicating work? I've been looking at using autotest, but it seems a bit abandoned lately. Would be grateful for any pointers or ideas. Thanks! - Chris. -- Chris Ball <cjb(a)laptop.org> <http://printf.net/> One Laptop Per Child

Announcement: Linaro ARM Optimized Toolchain for Android platform

by Jim Huang

Hello list, Today we're announcing a new technical preview of ARM optimized toolchain for Android platform by Linaro[1]. Linaro is a NFP (Not For Profit) organization that aims to make embedded open source development easier and faster. Regardless of Android release cycle from AOSP, Linaro would like to bring the latest and ARM optimizing open source technologies to the common software foundation for software stack, and Linaro toolchain[2] deals with all aspects of system-level tools - the core development toolchain (compiler, assembler, linker, debugger). In this announcement, the technical preview of ARM optimized toolchain for Android is available for evaluation: (source repository and binary package) https://wiki.linaro.org/Platform/Android/Toolchain An early activity of the Android Platform Team has been to run the Android benchmark suite to show the gains possible in going from the default Google 4.4 based toolchain to the Linaro 4.5 toolchain. The experimental benchmarks were run on a 600 MHz Cortex-A8 board running Android 2.2: (unofficial, for reference only) https://wiki.linaro.org/JimHuang/Sandbox/LinaroToolchainAndroidBenchmarking Developers can utilize the optimization techniques from GNU Toolchain and Linaro's ARM improvements through Linaro Toolchain for Android and NDK. For example, skia benchmark[3] brings 11% performance improvements after using Linaro Toolchain. Linaro's Android platform team plans to deliver the final linaro-11.05 release, and you can check out the status of open development: https://launchpad.net/linaro-android/ On-going Blueprints: https://blueprints.launchpad.net/linaro-android/+spec/linaro-android-toolch… https://blueprints.launchpad.net/linaro-android/+spec/linaro-android-toolch… https://blueprints.launchpad.net/linaro-android/+spec/linaro-android-google… Sincerely, Jim Huang, Android platform team, Linaro [1] http://www.linaro.org/ [2] https://wiki.linaro.org/WorkingGroups/ToolChain [3] Linaro uses the same toolchain benchmark as Google compiler team does: https://wiki.linaro.org/Platform/Android/UpstreamToolchain

ARM/Thumb-2 kernel size comparison

by Dave Martin

The question of the size impact of building the kernel in Thumb-2 came up to day, so I extracted some quick numbers: $ size vmlinux-* text data bss dec hex filename 8420507 463356 826928 9710791 942cc7 vmlinux-arm 6715539 463260 826928 8005727 7a285f vmlinux-thumb2 This is for a recent mainline kernel built with the linaro omap config. In this case we save about 20% for code and read-only data (i.e., text) and 17.5% overall -- which accounts for a little under 2MB saved in this example. This doesn't take loadable modules into accout; we can probably expect to see a similar size ratio there. Cheers ---Dave
