Add board config fragments to llct? (Re: Would like to add couple conf files to the config-boards-tracking branch)

Yes, I see the problem. But getting CI jobs to pull configs direct from an LT tree seems like the wrong solution. I guess what people really need is configs in linux-linaro-core-tracking (llct) (I'm sure people have told me that before and I possibly didn't listen enough). Now that the LT branches included in linux-linaro (ll) are based on llct, then they could modify the board configs in llct if required for the work in their topics. So at the moment, I can't think of a good reason not to pub all the board configs into llct. Can anyone else? I don't know if we need the board configs to be sourced from a single repo, or allow board configs to be included in llct from LT trees. One central repo means that people know where to go but means everyone will be pushing to the same repo which could get a bit messy. (Unless we had an official maintainer to manage all commits to the tree.) Or course, once Linaro's build and test infrastructure supports config fragments fully, then we could have have separate config fragments for - basic board config - new board enablement - special features (e.g. big.LITTLE MP) - testing or benchmarking config and the configs could live in the tree relevant to the code they apply to rather than having a single central board config we have to manage. -- Tixy

by Botao Sun

Calendar Week 46: Here is test result summary for Linaro ubuntu image on following boards: 1) ARM Versatile Express A9; 2) Samsung Origen; 3) TI Panda Board 4430; 4) TI Panda Board 4460. Synopsis: Feature status remain the same on vexpress A9, Panda 4460 and Samsung Origen. Power Management test passed on Panda 4430. 1. vexpress A9 + ubuntu (Column AH): https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AroPySpr4FnEdFNmV… Features' status is exactly same as previous week. Device Tree and video playback are unavailable. 2. Origen + ubuntu (Column AC): https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AroPySpr4FnEdEowN… Unity 3D, Hardware Acceleration, WiFi, Bluetooth and Video Playback are unavailable, Power Management test still failed in this image. 3. Panda 4430 + ubuntu (Column AE): https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AroPySpr4FnEdEwwZ… All Power Management tests passed on this build. Bluetooth is unstable and it works better on Panda 4460. Suspend / Resume doesn't work. 4. Panda 4460 + ubuntu (Column AD): https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AroPySpr4FnEdEwwZ… The board can't find the other Bluetooth device every time, but after several repeats, it finally works. However, file transfer is unavailable. Audio input will be double checked next week. All other features look good. For the previous week (Calendar week 45) summary, please refer to attachment.

[PATCH] mtd: map: Fix compilation warning

This patch is an attempt to fix following compilation warning. In file included from drivers/mtd/chips/cfi_cmdset_0001.c:35:0: drivers/mtd/chips/cfi_cmdset_0001.c: In function 'cfi_intelext_write_words': include/linux/mtd/map.h:331:11: warning: 'r.x[0]' may be used uninitialized in this function [-Wmaybe-uninitialized] I could have used uninitialized_var() too, but didn't used it as the final else part of map_word_load() is missing. So there is a chance that it might be passed uninitialized. Better initialize to zero.

[ANNOUNCE]: big LITTLE MP tree process update

by Viresh Kumar

Hello everybody, There have been few discussion on how big LITTLE MP tree should be managed as it is getting PULL requests from a wide range of patches working towards making our system more power efficient. The following scheme is finalized and is detailed here: https://wiki.linaro.org/WorkingGroups/PowerManagement/Process/bigLittleMPTr… Purpose of this tree is to keep all ongoing efforts, which affect power management on big LITTLE systems, together at a single place. All of these must be targeted to get included in Mainline by their original authors. There are two categories of branches/patches that are kept here. One that are guaranteed to work on current big LITTLE system (Tested on ARM Vexpress TC2) and others which are experimental. Branches can be moved from experimental to master, once we are convinced they don't break any existing stuff in master branch. So, following is the category of Merge branches we have: big-LITTLE-MP-master-v*: Guaranteed to work on current big LITTLE system, ARM Vexpress TC2. This will be pulled in linux-linaro-tracking git tree. big-LITTLE-MP-experimental-v*: Experimental topic branches For now I have created to merge branches: - big-LITTLE-MP-master-v12: git merge arm-multi_pmu_v2 hw-bkp-v7.1-debug-v1 per-task-load-average-v3-merged task-placement-v2 task-migration-sysfs-tuning misc-patches config-fragments - big-LITTLE-MP-exp-v12: git merge intel-powerclamp-driver-v1 per-entity-load-tracking-with-core-sched-v1 sched-pack-small-tasks-v1 sched-timer-wq-migration-v2-resend - power-aware-scheduling-v1: This is another branch which is present in this tree, which can be used. It was rebased on tip/master and hence isn't merged. PULL request to Andrey would be sent only for the Master branch. I would be releasing Experimental branch too every time with Master branch though. Please share your comments? -- viresh
