Roadmap Cards: Improving HMP Linux scheduling - http://cards.linaro.org/browse/CARD-190

Blueprints and bugs are all now in a single Launchpad project for big.LITTLE: https://launchpad.net/linaro-big-little-system

Version 15 of big LITTLE MP has been pulled into the baseline.

Updates: ------- - Rebased over 3.8-rc7 - Stats: Total distinct patches: 36 - Dropped Patches: Two patches from cpufreq-fixes-v2 (3): causing some failures.

Details: http://lists.linaro.org/pipermail/linaro-dev/2013-February/015370.html

Items under review: =================

Bugs fix submissions: 1 - Fix the nr_busy_cpus to prevent spurious Idle Load Balance 2 - Fix the load tracking with RT tasks 3 - Fix the active migration when 1 task is running on the pulled CPU

Patches: 1 - Packing small tasks 2 - Force migration of a standalone long running task for LITTLE to big 3 - Use per task load tracking to evaluate the CPU load instead of the nice priority 4 - Don't move small tasks during periodic load balance, packing small tasks will do it for us so the scheduler should focus on long running tasks 5 - Tune sched_domain for HMP
