How is per task load being accounted in the HMP scheduler?

by Nitin Chaudhary

Greeting! I am interested in understanding the load computation logic in the scheduler designed by Linaro for HMP systems at the *http://releases.linaro.org/14.09/members/arm/android/images/armv8-android-juno-lsk <http://releases.linaro.org/14.09/members/arm/android/images/armv8-android-j…>* for Juno Board. While going through the scheduler code in kernel/sched/core.c, I am unable to understand how the per task load is being accounted in the code. Any pointers will be very helpful and apologies if its a too trivial query. Regards, Nitin

[ANN] Small git service updates

by Paul Sokolovsky

Hello, Systems team recently made some cleanups and elaborations to Linaro git services, information about which we'd like to share here. None of these changes require immediate changes on your side (compatibility with old usage ways is kept), but we'd like to draw some attention to them anyway, as they should make life a bit easier, especially for newstarters, so it would be nice if people were aware of them and not pass old information around. 1. To access gitolite push services, "git" user is now used consistently across various hosts. (Previously, it was "git" for the main server, git.linaro.org, but various other names on team- and project-specific servers). Old names are kept for compatibility, but you will see "git@" in gitweb, and that's the preferred way to pass links to other people. 2. Our initial instructions for git services included steps of update user's SSH config in ~/.ssh/config. Based on the experience, we found that lead to confusion and surprises (for example, if you switched workstation or resetup one from scratch). So, this usage is deprecated now - instead, SSH repo URLs should contain explicit username ("git@", per above). Instructions were updated correspondingly. You can keep using your existing SSH config and cloned repos, just please pass fully specified clone URLs to other people. Summing up: You can look up authoritative access URLs for a repo in gitweb. E.g.: https://git.linaro.org/boot/u-boot-linaro-next.git . If you need to pass git clone info to other people, please use what's written there (giving gitweb URL is probably the easiest). You don't need to change anything on your side. -- Best Regards, Paul Linaro.org | Open source software for ARM SoCs Follow Linaro: http://www.facebook.com/pages/Linaro http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog

Ubuntu Vivid Vervet test rebuilds (all components, all architectures)

by Matthias Klose

A test rebuild of Vivid Vervet was started this week for all architectures, and is finished for the main component. Results can be found at http://people.ubuntuwire.org/~wgrant/rebuild-ftbfs-test/test-rebuild-201502… The archive for the test rebuild is https://launchpad.net/ubuntu/+archive/test-rebuild-20150202/ Additional build failures for packages in vivid-proposed (not yet in vivid) can be found at http://qa.ubuntuwire.com/ftbfs/ Please help fixing the build failures. Matthias PS: A second test rebuild (using a snapshot of GCC 5) is currently running, in preparation of the move to GCC 5 in 15.10. This can be found at http://people.ubuntuwire.org/~wgrant/rebuild-ftbfs-test/test-rebuild-201502… https://launchpad.net/ubuntu/+archive/test-rebuild-20150202-gcc5/ The corresponding compiler packages are in the PPA https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test/ ... just in case you want to make packages ready for GCC 5.
