Postmortem and lessons learned for Linaro's release 2012.10

https://wiki.linaro.org/Cycles/1210/Release/Review

Highlights and Key Successes ============================ http://www.linaro.org/downloads/1210

Linaro is now making early ARMv8 images available to interested developers. For a primer on the ARMv8 architecture, the AArch64 execution state and the A64 instruction set, please visit the ARM portal. While there is currently no ARMv8 hardware available, ARM and Linaro have developed support for AArch64/A64 against virtual platforms and started sending the resulting patches to various open source projects. For more information on these ARMv8 images please take a look at the Linaro Engineer pages on the Linaro website.

Work on big.LITTLE continues as the Linaro Kernel Working Group highlights its completion of TC2 support; noting that TC2 now boots with the latest IKS tree. Five new test cases have been added to handle simultaneous thread switching, important bugs such as Switcher Thumb-2 bug and Switcher deadlock issue when working on the memblock_steal(), vlock remaining locked under certain conditions were fixed along with and updated focus to run benchmarks with the latest IKS on TC2 to find optimization opportunities.

Postmortem and Lessons Learned ============================== As a better way for the integration groups to prioritize their planning for each cycle, the platform group has begun to implement a short planning sign-off session for each team. After the team plans the milestone, plans will be reviewed and signed off. The general question that is to be answered is that "for this cycle is the roadmap story complete?" The format incorporates * Roadmap Card Review * General Planning * blueprints * bugs * maintenance * Resources * vacations * vacancies * action items

One item that continues to irritate is the TC2 board that is stuck in customs in India. A major effort was expended to try and free it, but it is still in stasis.

Blueprints ========= The number of high or essential priority blueprints that missed the cycle: Android 4 out of 13 Developer Platform 3 out of 7 Infrastructure 3 out of 6 Lava 3 out of 7 QA 2 out of 5 Total 15 out of 38

39% of high or essential priority blueprints scheduled for this cycle were not delivered.

Total blueprints: 27 out of 54 missed the cycle.

High priority missed blueprints recap: 12.05: 19 out of 48, 39% 12.06: 13 out of 31, 42% 12.07: 14 out of 31, 45% 12.08: 6 out of 26, 23% 12.09: 9 out of 28, 32% 12.010: 15 out of 38, 39%
