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.

Question on Android Linaro

by Dima Kostenich

Hi guys, One of my active research tasks at the moment is to characterize and understand the endurance issues related to the eMMC products in Android environment. So that's why I need to profile eMMC protocol on active working system under some circumstances. I tried first to do it with Android Emulator from Android SDK but unfortunately eMMC here is only used by the SD Card emulation at that point, while for the internal disk images NAND is used. And I need to see how Android works exactly with its internal eMMC storage and not external. So my questions are: 1) Does Android Linaro provides the possibility to emulate internal disk images with eMMC? 2) And if does, what is the situation with running Android Linaro in virtual environment (let's say QEMU for example) ? Hope to get any answers or hints from you. Thanks a lot! -- Best Regards, Dima Kostenich

FBIOPAN_DISPLAY or FBIOPUT_VSCREENINFO

by Amit Pundir

I was going through this patch of ours "gralloc: Use FBIOPAN_DISPLAY instead of FBIOPUT_VSCREENINFO to refresh display" http://android.git.linaro.org/gitweb?p=platform/hardware/libhardware.git;a=… and was wondering if we need to update this patch. The rationale behind this patch is that the PUT_VSCREENINFO implementation of iMX53 Fb driver was broken at that time https://bugs.launchpad.net/linaro-android/+bug/824506 so we switched to PAN_DISPLAY. Here is an old but relevant discussion on this topic on android-porting list https://groups.google.com/d/msg/android-porting/6Tn36GpVWJI which say that the correct way to go forward is PAN_DISPLAY and put PUT_VSCREENINFO as a fallback option. Which sounds about right. The only thing which is confusing here is that the fb kernel documentation suggest to use PAN_DISPLAY if we want to pan the screen only (i.e. only xoffset and/or yoffset are modified) and use PUT_VSCREENINFO otherwise. And in this particular case we modify other screen info variables as well (e.g. activate), should we still be doing PAN_DISPLAY then? Regards, Amit Pundir
