Need Help to fix GPU adreno 305

[walidham]

Hi
I need help to fix this problem.
I'm try to port UBT to Moto G 2014, the phone boot, but no graphic
This is log cat
dmesg
test_egl :

@walidham Probably you are missing this file from your vendor or device tree? egl/eglsubAndroid.so - maybe its not copied into your system image. You can check also in out/system or so directory

[walidham]

eglsubAndroid.so exists in folder vendor/lib/egl
when i added symlink to vendor/lib/egl/ folder like this
ln -s /vendor/lib/egl egl
the ubuntu touch boot animation display but stuck on it and i got this message again

os_lib_map error: dlopen failed: , on 'egl / eglsubAndroid.so'
Unable to load egl/eglsubAndroid.so

@Flohack Hi thank you very much sir
When i aded symlink to vendor/lib/egl folder in root i got this when run test_hwcomposer

root@ubuntu-phablet:/# test_hwcomposer

@walidham Yes you are missing more than just one file. You need to also find libGLESv2S3D_adreno.so somewhere. The /vendor/lib prefix is strange.

[walidham]

@Flohack YESSSSS i do it, now Ubuntu Touch start
I will fix RIL for the first urgent feature and after camera.
Do i need patch kernel for apparmor ?

[flohack]

@walidham Please send SCREENSHOT!

apparmor you will need for click apps yes, but there is a description somewhere about how to disable apparmor for testing. You find it in Google, just look for Ubuntu Touch apparmor howto or such a thing.

[walidham]

@Flohack this is first image Ubuntu Touch in Moto G 2014

I will change kernel with kernel used in SailfishOS (its work fine in moto g 2014 sailfishos) , hope this will resolve many pbs

@walidham Beautiful! You are really skilled then, not many people can port in the first go so that they get a usable screen.

You can follow these items roughly to see if you got all things covered:

AppArmor
Bluetooth
Boot
Camera
Cellular Radio
GPS
Graphics
Resume
Rotation
Sound
Touch

Why is touch at the bottom? I'd consider that somewhat more important.

I think from a quick look that it is just posted in alphabetical order

[flohack]

@Leppa Please, this is NOT ordered by importance

@Flohack Hi can you help me to understant this error :

E/adsprpc ( 0): vendor/qcom/proprietary/adsprpc/src/apps_std_imp.c:33:apps_std fopen failed: ./oemconfig.so No such file or directory
E/adsprpc ( 0): vendor/qcom/proprietary/adsprpc/src/apps_std_imp.c:33:apps_std fopen failed: /system/lib/rfsa/adsp/./oemconfig.so No such file or directory

btw camera(photo) , power buton, rotaion work.
what no work : ril, audio, wifi,....

full logs logcat

[flohack]

@walidham Hello, sorry no...

You might want to take a look at CM/Lineage sources if they somewhere include a file called oemconfig.so - which source does your vendor tree come from? TheMuppets?

BR

[walidham]

@Flohack Hi, wifi fixed, amazon & ebay application work, but browser, facebook and twiter crash .

For vendor, yes i used TheMuppets, cm-12.1 device tree and cm12.1 kernel with small modification in 4 files (fix boot.img size, compilation errors...)
I think RIL not work due to this error of file oemconfig.so.
I think need more debug for it

[flohack]

@walidham Crashing Apps can be an indication that your apparmor does not work... Did you apply those patches already?

BR

[walidham]

@Flohack in wiki ubuntu guide its not clear how to patch apparmor, i will try to do it.
The audio is not working, is it related to apparmor ?
Also i found that RIL is related to audio, i think fix audio will fix RIL, right ?

[flohack]

@walidham I was never so far that I could see if audio or RIL works. But maybe yes.

Which kernel version do you have? I just replaced the apparmor folder completly with the backport version. Dunno if this will be enough but it looked so far ok

BR

[walidham]

@Flohack i used motorola kernel msm8226 v 3.42.
Can u give me the link the backport version.
Also many thanks for reply
Best Regards

@walidham See https://developer.ubuntu.com/en/phone/devices/porting-new-device/ => Scroll down to "Device-specific changes" => Scroll further down to "AppArmor" and you see a list of links for that. Found it?
