Tools of updating kernel related files for android

by YongQin Liu

Hi, All Android team now has tools for updating the kernel related files without recreating the sdcard. The detail information about the tools is described here: https://wiki.linaro.org/Platform/Android/KernelUpdateTools And here just list some examples: 1. update all the kernel related files with boot.tar.bz2 ./update-android.sh out/target/product/pandaboard/boot.tar.bz2 2. only update one file that will be in the boot.tar.bz2 when packaged, Like board.dtb/uImage/cmdline ./update-android.sh out/target/product/pandaboard/boot/board.dtb ./update-android.sh out/target/product/pandaboard/boot/uImage ./update-android.sh out/target/product/pandaboard/boot/cmdline 3. update all kernel modules. ./update-android.sh out/target/product/pandaboard/obj/kernel 4. update files in uInitrd ./update-uInitrd.sh /tmp/init.rc this will replace the /ini.rc file in uInitrd with the passed /tmp/init.rc Hope these tools will be helpful during your development of android. Any comments/suggestion, please feel free to send to me.

W/SchedPolicy( 1193): add_tid_to_cgroup failed to write '1263' (Permission denied); policy=1

by Zach Pfeffer

So I think this issue may be Android kernel related, because we seem to be the only ones hitting it. This seems to imply that there's a kernel change we don't have or the kernel has changed in our newer versions. The symptom is: W/SchedPolicy( 1193): add_tid_to_cgroup failed to write '1263' (Permission denied); policy=1 W/ActivityManager( 1193): Failed setting process group of 1263 to -1 W/System.err( 1193): java.lang.SecurityException: No permission to set to given group W/System.err( 1193): at android.os.Process.setProcessGroup(Native Method) W/System.err( 1193): at com.android.server.am.ActivityManagerService.updateOomAdjLocked(ActivityManagerService.java:13516) W/System.err( 1193): at com.android.server.am.ActivityManagerService.updateOomAdjLocked(ActivityManagerService.java:13636) W/System.err( 1193): at com.android.server.am.ActivityManagerService.updateLruProcessLocked(ActivityManagerService.java:1903) W/System.err( 1193): at com.android.server.am.ActiveServices.realStartServiceLocked(ActiveServices.java:1089) W/System.err( 1193): at com.android.server.am.ActiveServices.attachApplicationLocked(ActiveServices.java:1472) W/System.err( 1193): at com.android.server.am.ActivityManagerService.attachApplicationLocked(ActivityManagerService.java:4269) W/System.err( 1193): at com.android.server.am.ActivityManagerService.attachApplication(ActivityManagerService.java:4317) W/System.err( 1193): at android.app.ActivityManagerNative.onTransact(ActivityManagerNative.java:386) W/System.err( 1193): at com.android.server.am.ActivityManagerService.onTransact(ActivityManagerService.java:1675) W/System.err( 1193): at android.os.Binder.execTransact(Binder.java:351) W/System.err( 1193): at dalvik.system.NativeStart.run(Native Method) Looking back at top: I have: 1193 0 0% S 70 548684K 42168K fg system system_server 1263 0 0% S 13 476904K 36216K fg u0_a27 com.android.systemui so system_server is attempting to write com.android.systemui and its getting an error. The relevant native function seems to be: /workspace/androids/4_juice-aosp/system/core/libcutils/sched_policy.c I saw that Tixy also hit this, https://bugs.launchpad.net/linaro-landing-team-arm/+bug/1037611 ..but that the bug never got assigned, etc... I tried setting: chmod 0660 /dev/cpuctl/tasks to chmod 0666 /dev/cpuctl/tasks but didn't see any difference. This change from the Android automerger, seems to be related: https://android.googlesource.com/platform/system/core/+/d7562ee3d61504ba5d2… I also found what appears to be a workaround: https://android.googlesource.com/platform/frameworks/native/+/f30fd01497a53… Looking at additional logs I see what looks like an attempt to put the process that needs to get changed into the right group: W/System.err( 1192): java.lang.SecurityException: No permission to set to given group W/System.err( 1192): at android.os.Process.setProcessGroup(Native Method) W/System.err( 1192): at com.android.server.am.ActivityManagerService.updateOomAdjLocked(ActivityManagerService.java:13516) W/System.err( 1192): at com.android.server.am.ActivityManagerService.updateOomAdjLocked(ActivityManagerService.java:13636) W/System.err( 1192): at com.android.server.am.ActivityManagerService.updateLruProcessLocked(ActivityManagerService.java:1903) W/System.err( 1192): at com.android.server.am.ActiveServices.realStartServiceLocked(ActiveServices.java:1089) W/System.err( 1192): at com.android.server.am.ActiveServices.attachApplicationLocked(ActiveServices.java:1472) W/SchedPolicy( 1192): add_tid_to_cgroup failed to write '1268' (Permission denied); policy=1 W/ActivityManager( 1192): Failed setting process group of 1268 to -1 W/System.err( 1192): at com.android.server.am.ActivityManagerService.attachApplicationLocked(ActivityManagerService.java:4269) W/System.err( 1192): at com.android.server.am.ActivityManagerService.attachApplication(ActivityManagerService.java:4317) W/System.err( 1192): at android.app.ActivityManagerNative.onTransact(ActivityManagerNative.java:386) W/System.err( 1192): at com.android.server.am.ActivityManagerService.onTransact(ActivityManagerService.java:1675) W/System.err( 1192): at android.os.Binder.execTransact(Binder.java:351) W/System.err( 1192): at dalvik.system.NativeStart.run(Native Method) 1192 0 0% S 71 549636K 42460K fg system system_server 1268 0 0% S 14 477920K 36224K fg u0_a27 com.android.systemui >From these logs I think system_server is trying to put com.android.systemui into the bg because its using a lot of CPU, but it can't because it either doesn't have access or something else is going on. Anyhow, attached some logs from a first boot scenario. Any help or insight would be great. -- Zach Pfeffer Android Platform Team Lead, Linaro Platform Teams 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

Building for i.MX53 QSB (or loco or whatever it is called)

by Espen Frimann Koren

Hi. I followed the documentation on https://android-build.linaro.org/builds/~linaro-android/imx53-ics-gcc47-fre… on Ubuntu 10.04 x86_64 LTS. I of course had to install gcc-4.7 first, but that was easy to find on the Internet. My problem it seems is some lines like the following (for libgcc_s.so and libgcc.a too): /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.7/libstdc++.so when searching for -lstdc++ It ends in: make: *** [out/host/linux-x86/obj/EXECUTABLES/fs_get_stats_intermediates/fs_get_stats] Error 1 make: *** Waiting for unfinished jobs.... make: *** [out/host/linux-x86/obj/EXECUTABLES/mkbootfs_intermediates/mkbootfs] Error 1 The last line before the /usr/bin/ld lines and the make -lines is: target StaticLib: liblog (out/target/product/iMX53/obj/STATIC_LIBRARIES/liblog_intermediates/liblog.a) Btw. I also tried the binaries from http://releases.linaro.org/images/12.03/android/imx53-ics-gcc46-freescalelt…, but I didn't get it to boot with the LCD screen. I tried to do manually from uboot the same as the boot.scr script does, but I didn't get the screen anyway. Sp1

tracking-vexpress and tracking-origen builds updated

by Axel Fagerstedt

Hi all, We have been working on unifying the tracking-origen and tracking-vexpress android manifests into one. The last bits and pieces went in last week and I was finally able to update the official builds this weekend. There are some changes you should be aware of: - tracking.xml introduced which supports both devices - kernel and u-boot are now located under kernel/linaro/<device> and u-boot/linaro/device - tracking.xml uses repo groups to enable synching of only those gits needed for either device (more on this below) I will push a patch to remove the old manifests today. We hope to move more devices to this format going forward. To use the repo groups support use the -g flag when you do repo init. $ repo init -u ... -b ... -m tracking.xml -g "group1, group2,..." There are currently 3 groups you need to be aware of: 1. common, all gits which are common 2. origen, all gits which are specific for origen 3. vexpress, all gits which are specific for vexpress Getting the vexpress code (for instance): $ repo init -u ... -b ... -m tracking.xml -g "common,vexpress" A REPO_GROUPS build config parameter has been introduced to android-build.linaro, both the official builds are using it. Regards, Axel
