Roadmap Cards ============= http://cards.linaro.org/browse/CARD-34 Issue: mobile work use cases are not progressing - dmitry to change focus and get something out based on perf record and playback - will get 2 or 3 synthetic workloads before plumbers conference
http://cards.linaro.org/browse/CARD-35 Hotplug optimisations looking good and more on the way in 3.6 and 3.7: https://wiki.linaro.org/WorkingGroups/PowerManagement/Doc/Hotplug#CPU_hotplug_on_latest_kernel Blueprints ========= https://blueprints.launchpad.net/linaro-power-qa/+spec/emulating-a-big-little-system - The work has been done, and tested. - No one is using it at the moment. - tools available on git.linaro - HW availability supersedes this blueprint internally https://blueprints.launchpad.net/linaro-power-kernel/+spec/bl-mp-integration-tree - this functionality is being covered by ARM Landing team - linunxLinaro integration https://blueprints.launchpad.net/linaro-power-kernel/+spec/sched-add-asymmetric-cpu-support-to-scheduler - merged and accepted https://blueprints.launchpad.net/linaro-power-kernel/+spec/perf-record-replay - Broken in mainline, dmitry is working on fixing it. - A few days of work. - will publish basic use case to linaro dev - re-target to august release https://blueprints.launchpad.net/linaro-power-kernel/+spec/big.little.mp-hotplug-performance-improvements - Continuing inspection of RCU for issues with __stop_machine weaning. - Thomas Gleixner's patches should be set for 3.7 -- infiniband testing complete, lack of which prevented 3.6. - Designing alternatives for faster stop_cpu() work (which is current replacement for __stop_machine()) -- low priority tasks for stop_cpus() actually slows things down under load compared to stop_machine(). https://blueprints.launchpad.net/linaro-power-kernel/+spec/cpuidle-add-cpu-specific-states-capability - proposal being discussed on the mailing list. - d lezcano is on vacation but will collate feedback and respond. - little opposition https://blueprints.launchpad.net/linaro-power-kernel/+spec/cpuidle-upstream-improvements - remaining items have been discussed as part of previous blueprint. Miscellaneous items ================= Testplan - Dates added to dependency table - Not much testing progress due to lack of hardware - For testing to ramp up we need platforms to test on ie: TC2 hardware Android - progress on fastmodels! - amit p has bootwrapper in place - boots with kernel from switcher project, not working with linux-linaro yet TC2 enablement has been integrated into the linux linaro tree. Asymmetric support for ARM accepted by Russell and is already merged into 3.6 Linux kernel Thomas Gleixner's kthreads infrastructure patches are now in git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git on the branch tip/smp/hotplug. There is an updated project plan at https://docs.google.com/a/linaro.org/document/d/1XI9FaEd6dYfCEDezboF7gWtrTOmOrShUVoDOy1hr-5I/edit# -- David Zinman Linaro Release Manager | Project Manager Linaro.org | Open source software for ARM SoCs _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
