Announcement: ============= It is regretful that Paul Larson will be returning to Canonical after this week. I want to personally thank Paul for the huge effort and creativity that he has given to the big.LITTLE projects. Each project would have been poorer without his input. Naresh will continue to be a great asset to the team on QA and Alexander Sack will be filling in for Paul as the search continues for a QA team lead. Roadmap Cards ============= http://cards.linaro.org/browse/CARD-34 and http://cards.linaro.org/browse/CARD-35 are being closed out and planning has just begun for the next series of Linaro roadmap cards for big.LITTLE MP. Stay tuned for links. Blueprints ========= https://blueprints.launchpad.net/linaro-power-kernel/+spec/perf-record-replay - Done as of 3.6-rc1 but not integrated into Linaro LEBs yet. https://blueprints.launchpad.net/linaro-power-kernel/+spec/big.little.mp-hotplug-performance-improvements - In progress, target for 12.09 cycle https://blueprints.launchpad.net/linaro-power-kernel/+spec/cpuidle-add-cpu-specific-states-capability - In progress, target for 12.09 cycle https://blueprints.launchpad.net/linaro-power-kernel/+spec/cpuidle-upstream-improvements Work to be completed this cycle, unfinished items may be included in a new blueprint. https://blueprints.launchpad.net/linaro-qa/+spec/sched-test-porting-to-android - in progress Miscellaneous items ================= Main changes for V7 of MP pull - Based on v3.6-rc3 - per-task-load-average updated with v3 - applied Tixy's patch from fast-slow-cpu-dt-v1 to task-placement-v1 as they are somewhat related only. And so removed fast-slow-cpu-dt-v1 branch We've received some feedback from out big.LITTLE TC2 build: · The image boots fine. · Successfully ran: Sunspider, V8, 0xbench 2D and 3D tests · Problems: Random crashes during BBench and web-browsing. a) Downloaded the pre-built image from link given by Linaro (OK) b) Copying the image on the SD card (OK) c) Copying SD card contents to NOR flash (Issues, finally OK) - copy boot/v2p-ca15-tc2.dtb /media/VEMSD/SOFTWARE/TC2/tc2_dtb.bin should be corrected by Linaro as cp /media/boot/v2p-ca15-tc2.dtb /media/VEMSD/SOFTWARE/TC2/tc2_dtb.bin - People familiar with it may not have a problem, but novices like me to the setup follows the instruction by letter! - I made a silly mistake also at this stage where i misspelled the extension, and later when i tried to boot the board in the POST step it failed unable to locate the device tree description file. - Before ejecting the cards issued a ‘sync’ command (following advice from others). d) Boot the board (Issues, finally OK) - Discovered a further mistake made in the images.txt edit and bootscr.txt which caused the flashing and booting up of image to fail respectively. - Corrected both these typo issues and now i have got android booted up. Summary: With the pre-built image option and instructions provided user was able to flash the device successfully and see the android boot up screen. Only small issue is the above copy instruction mentioned in step c) in Linaro web page slightly incomplete, otherwise their instructions were good.
