Upcoming android-build.linaro.org migration (and disk space)

by Paul Sokolovsky

Hello, We're finishing migration of ci.linaro.org to the latest Ubuntu LTS release (14.04). android-build.linaro.org is next in queue. I guess, it makes sense to plan migration for the same time window as ci.l.o - past-release, first week of July. But maybe Android team has special plans or suggestions, so please let us know. This would also be good time to discuss any changes or additional requirements for the migration. Actually, just today Fathi drew my attention to the fact that there were less 5% free on a-b jobs partition. Looking forward to upcoming migration, I did thorough clean up - we now back to 11% free, and that's actually 55Gb. I also did analysis of growth rate, and my calculations give below 7Gb/year. I hope that's not surprising - most builds we produce, also expire soon, so only growing residue is actually release builds. So, based on this analysis, we should be fine for next couple of years. You're free to disagree of course. Then I can propose 2 solutions: 1. Reconsider how 500Gb there is used. What suggests of such approach is example, ci.linaro.org, which has a lot of jobs, but of whose 300Gb, 60% are free. That's apparently because it uses much more aggressive expiration policies - for example, unneeded jobs there are actually deleted. Applying that idea to a-b, the build/CI server, do we really need to host old historical releases there, if their official place is https://releases.linaro.org anyway? I guess, that's Fathi call too. 2. If we don't want to change retention policies, and don't trust small growth rate figure either, then increasing disk space is the obvious choice. But I'd say extra 100Gb would really be enough for foreseeable future - having too big a disk means more money (include back up cost), more time when you need back up soon, more fsck time, etc., etc. I don't think there's much more to vary with this migration between new Jenkins version (implied) and disk space, but if somebody knows other issues which would be nice to fix, let us know (but again, talk is just about Jenkins master, not slaves or something else).

Support for java6 and java7 on android-build

by Paul Sokolovsky

Hello, Last Friday, we with Vishal made changes to build scripts on https://android-build.linaro.org/ to support both java-1.6-sun (as was required by previous AOSP versions) and java-1.7-openjdk (as should be required for AOSP master). (Based on https://bugs.launchpad.net/linaro-android-infrastructure/+bug/1310939) To explicitly select java6, add "USE_JAVA_6=1" to build config. For java7 respectively add "USE_JAVA_7=1". The default stays java6 so far, as it appears to be needed by the most jobs so far, but it may be changes in the future. Thanks, and let me know if there're any issues or questions. -- Best Regards, Paul Linaro.org | Open source software for ARM SoCs Follow Linaro: http://www.facebook.com/pages/Linaro http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog

Optimizing OVERLAY handling on android-build

by Paul Sokolovsky

Hello, There were increasing Android build times during last month again (going over 3.5hrs). Yesterday, I re-created the seed, but that didn't improve times match. I did more stats on builds and it turns out that we spend almost 1.5hrs in copying ever-growing overlay collection to the slaves via sluggish CopyToSlave Jenkins plugin. That's issues known for at least half-year, and was in queue for being reworked. I didn't work on android-build closely for few months, but now that I'm back on maintenance, I'd like to start with fixing this long-overdue issue. The idea was to pull all the needed overlay, straight to a slave. The complication here was handling of license protected files. ci.linaro.org had the same issue, and used a script to handle automatic downloads for some time. However, as of now, it was switched to other process and the script git bitrotted with recent linaro-license-protection codebase changes. I took a look at revamping it, but then though that it may be a good idea to use simpler and more explicit process, following closely click-thru usage. So, if you want to use a license-protected binaries in a build, you'd need to specify: ACCEPT_LICENSE=<license_id> Where <license_id> is id under which license is registered in linaro-license-protection. One good way to figure it out is to read the license page at all (well, as HTML source, the id is included in some links). Wording of variable name (as well as of commands in underlying implementation) is also explicit to point that its usage construes license acceptance. I prototypes these changes using https://android-build.linaro.org/builds/~pfalcon/panda-jb-gcc47-tilt-tracki… which is down to 2h10m build time. I'm ready to migrate all builds tomorrow, while we're early in cycle start. Please let me know if there're any issues with approach or proposed migration timeframe, otherwise let's make android-build rock again.

How to configure UEFI to specify the SD card as a boot device

by duqi

Hi, I have tried to boot the android on the versatile express. I have created the SD card according the links： http://releases.linaro.org/13.01/android/images/vexpress-linaro-mp Then I tried update the firmware according this links:http://releases.linaro.org/latest/openembedded/vexpress-lsk/#tabs-4 I set the two switchs to the off(just as both up) and I used the UART0. Now I meet a question about how to configure UEFI to specify the SD card as a boot device. When I give it power ,it does not appear the boot selection menu as expected. Could you give me some advices? Look forward to your favourable reply. duqi.

Running powerdebug on Linaro Android causes kernel crash on Samsung Arndale Board

by Mohammad Merajul Islam Molla

Hello, I ran powerdebug on Linaro Android 14.04 with a custom kernel (config file attached). While exporting gpios, it seems to crash the kernel (detail log attached). I have some printfs, added in powerdebug export_free_gpios() function to assist during log taking. for (i = 0 ; i <= gpio_max ; i++) { char command[50] = ""; printf("exporting gpio: %d\n", i); sprintf(command, "echo %d > /sys/class/gpio/export", i); printf("command: %s\n", command); if ((ret=system(command)) < 0) printf("error: failed to export gpio-%d\n", i); printf("ret: %d\n", ret); } >From log, it looks like while trying to export gpio 8, kernel crash is happening - "Unable to handle kernel NULL pointer dereference at virtual address 00000044" (details in attached log) >From output of /sys/kernel/debug/gpio it looks like gpio 8 is not mapped to any device.

Is it kernel bug? 2. Why are some gpios (8, 15, 24, etc) not mapped to any device on android? 3. Total GPIOs count differ on Linaro Saucy and Linaro Android on same board. Is this expected? -- Thanks, -Meraj
