[ANN] New private Git/Gerrit service available

by Paul Sokolovsky

Hello, Linaro Systems and ITS teams are glad to announce general availability of new generation of Private Git/Gerrit service. This service is the successor of https://linaro-private.git.linaro.org/ , older Git-only private service, and is based on underlying solutions which proved themselves well on public Linaro Git services, specifically: 1. https://dev-private-git.linaro.org offers Gitweb browser and Gitolite git self-management service. 2. https://dev-private-review.linaro.org adds change review capabilities for private projects using Gerrit. During the initial pilot period with couple of Linaro teams, requirements for secure private hosting were determined. It is based on providing each team a separate project area (identified by project path prefix), access control to which is governed by a specific LDAP group. Each project area is completely independent and not accessible to any other group. To start using the new private service, a manager of interested team should prepare and provide project prefix and LDAP group name, as explained above, and submit an ITS ticket in a usual way. More details of the initial setup, usage, and constraints of the service are available at https://wiki.linaro.org/Internal/Platform/Systems/GitPrivate We welcome teams interested in private Git hosting to take benefit of the new service, as well as teams which use older server at https://linaro-private.git.linaro.org/ to migrate to the new one. -- 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

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
