Analysis of JB tests and comparison with ICS

by Zygmunt Krynicki

Hey folks. I've ran a few builds to compare the tests that are present in JB builds as compared to its older ICS brother. Here are the results (I use 'maguro' to mean the JB build for nexus below) Tests present in both 'eng' and 'tests' variants of maguro: https://github.com/zyga/android-test-tools/blob/master/common-test-execs-ma… Additional executables present in 'tests' variant of maguro: https://github.com/zyga/android-test-tools/blob/master/extra-execs-maguro.t… Additional APKs present in 'tests' variant of maguro: https://github.com/zyga/android-test-tools/blob/master/extra-apks-maguro.txt Now having that I compared maguro to ICS panda builds with a new script i wrote (everything is in my git repo: https://github.com/zyga/android-test-tools the script is called compare-ics-and-jb.py) Delta between additional apks added by the 'tests' variant of JB: https://github.com/zyga/android-test-tools/blob/master/diff-ics-jb-apks.txt Delta between additional executables added by the 'tests' variant of JB (this delta is quite big): https://github.com/zyga/android-test-tools/blob/master/diff-ics-jb-execs.txt Delta between executables present in both 'eng' and 'tests' variant of JB: https://github.com/zyga/android-test-tools/blob/master/diff-ics-jb-common-t… So there you have it. BIG REQUEST: I would appreciate if anyone with access to JB and nexus could run the new test executables for me and send me the logs back. Thanks -- Zygmunt Krynicki Linaro Validation Team s/Validation/Android/

what's the story of the AOSP tests in our builds

by Alexander Sack

Hi, AFAIK, we reverted our experiments to use =eng instead of =test ... I understand this was done to prevent ICS/JB from slowing down due to hundreds of apps getting registered and displayed in the launcher... Now, what's the plan on how to get the AOSP tests produced in a way that we can run/use them? -- Alexander Sack Technical Director, Linaro Platform Teams http://www.linaro.org | Open source software for ARM SoCs http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog

memcpy() failure: bionic optimizations

by Annamalai Lakshmanan

Hi Bero, It is seen that latest bionic patches are causing Origen MM to crash, I just verified by removing the stream of bionic patches for optimization. There was a specific failure from memcpy(), this was due to 32 bit un-aligned address (Source Pointer) passed as an argument , this addess is obtained from mmap (device space) It looks like the latest optmizations are not taking this scenario into consideration and thus causing issues for specific case as mentioned above. I have not tried disabling NEON flag though. With Regards, Annamalai

Snowball: in rare cases, wpa_supplicant is started before the wlan driver could create the interface wlan0

by BENIGOT Yann

Hi, While working on a chrooted Android (the host distribution being a Debian one) stored in a tmpfs (in RAM), I noticed that, sometimes, enabling WLAN fails (the button goes straight from "On" to "Off"). On the console, the module was loaded ("CW1200 WSM init done"), but logcat showed that wpa_supplicant could not find the interface: E/wpa_supplicant( 8015): Could not read interface wlan0 flags: No such device E/wpa_supplicant( 8015): WEXT: Could not set interface 'wlan0' UP E/wpa_supplicant( 8015): wlan0: Failed to initialize driver interface D/wpa_supplicant( 8015): Failed to add interface wlan0 E/WifiStateMachine( 2292): Failed to start supplicant! When I put udev (in the host system) in charge of firmware loading, this bug always happens ; when I disable udev and let uevent (in the Android chroot) do the job, it only happens one time out of fifteen I would say. The problem seems to be that libhardware_legacy does not wait for the interface to be created to state that the driver has been loaded, leading the Wifi state machine in Android to load the supplicant before the interface was created. The patch at the end of this mail (concerning libhardware_legacy) enables libhardware_legacy to wait for the interface to be created in /sys/class/net, thus solving the problem. However, since this problem only occurs in rare cases when not using Linaro Android as intended (from emmc or sd card), I do not know if this is worth having a look at.
