Roadmap Cards =============
http://cards.linaro.org/browse/CARD-34 Closeout * A script has been created that emulates a big.LITTLE system on an x86 system by tuning down 2 processors in a cluster to emulate the A7 processors. * Simulation tools and corresponding descriptions are located at: http://git.linaro.org/gitweb?p=people/rob_lee/asymm_cpu_emu.git. * The perf record and playback feature allows a workload to be defined, recorded and then played back later. This has been released in 2012.07 LEB. It works in the mainline kernel as of 3.6-rc1 * A tools to create webkit-based web-browsing benchmarks was created (http://git.linaro.org/gitweb?p=people/antipov/testbrowser.git%3Ba=summary) * update the card closeout related to the pending deliverables for the simulator + workloads (mention that the simulator part was not complete, and more mobile workloads should be defined) and create a new card to handle that deliverable in Q3and create a new card for Q3 to cover these pending items
http://cards.linaro.org/browse/CARD-35 Closeout * Hotplug optimizations are in the git tree: git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq.git review-wq-hotplug. * Hotplug documentation is at: https://wiki.linaro.org/WorkingGroups/PowerManagement/Doc/Hotplug#CPU_hotplu... * Asymmetric support for ARM accepted by Russell and have been merged into 3.6 * Several cpuidle changes have already been accepted in mainline and adding cpu-specific idle tables is being reviewed currently.

Miscellaneous items ================= Fastmodels: - Kerrnel boots - booting with all cores , bootwrapper config needs more work. - Not released with LT this cycle
Testplan - Dates need to be revised - Testing blueprints are being drafted.
Big-LITTLE-MP-v5 (together with the updated multiplatform topic) has been merged into linux-linaro-core-tracking tree. The tag is llct-20120814.0. 1. Removed from this merge: - cpuidle-next-v4 - Already in rc1 - wq-hotplug-v1 - Already in rc1 - arm-asymmetric-support-v3 - Only one patch not mailined others are dropped 2. Rebased over v3.6-rc1 3. Extra patch from Morten/Tixy For a more complete list please see: http://lists.linaro.org/pipermail/linaro-dev/2012-August/013125.html
