Android glBindTexture crashing in offline trace

[mercutiogeek-2]

I’m trying to get traces working in my android app. Currently the first call to glBindTexture is crashing with the following callstack

 	libPVRTrace.so!CEs2ContextState::SetBoundTexture(unsigned int, unsigned int)()	C/C++<br />
libPVRTrace.so!Es2::_glBindTexture(unsigned int, unsigned int)()	C/C++<br />
libGLESv2_PVRTRACE.so!glBindTexture()	C/C++<br />
>	load_texture()	C/C++<br />
load_png_asset_into_texture()	C/C++<br />
LoadTextureInternal()	C/C++<br />
Render::LoadTexture()	C/C++<br />
BMFLoader::LoadTexture()	C/C++<br />
BaseModel::LoadModel()	C/C++<br />
OrbModel::Init()	C/C++<br />
OrbModel::OrbModel()	C/C++<br />
GMRenderTest::Update()	C/C++<br />
Java_com_novasapiens_Bacchus_BacchusView_GameLoopStep()	C/C++<br />
0x4179ba54	C/C++<br />
0x4179ba54	C/C++
```<br />
<br />
The call succeeds if I delete the profile settings file /data/data/com.powervr.PVRHub/pvrtraceconfig.json<br />
<br />
This is the code that is running:<br />
<code>	GLuint texture_object_id;<br />
glGenTextures(1, &texture_object_id);<br />
assert(texture_object_id != 0);<br />
<br />
glBindTexture(GL_TEXTURE_2D, texture_object_id);<br />
<br />
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR_MIPMAP_LINEAR);<br />
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);<br />
glTexImage2D(<br />
GL_TEXTURE_2D, 0, type, width, height, 0, type, GL_UNSIGNED_BYTE, pixels);<br />
glGenerateMipmap(GL_TEXTURE_2D);<br />
<br />
glBindTexture(GL_TEXTURE_2D, 0);<br />
return texture_object_id;<br />
</code><br />
The glGenTextures succeeds and I have a valid texture handle to bind to.  I tried moving the glTexParameters up to before the glBindTexture and they still succeeded.  It seems to specifically be an issue with glBindTexture.<br />
<br />
Any assistance would be appreciated.

Hi,



If you can share the following information with us, it will help us investigate the issue.

1. Which version of the PVRTrace recorder libraries are you using?
   
2. What version of Android are you recording your application on?


3. What graphics API are you using?


4. What happens if you call glGetError() after each call?


5. Can you share your pvrtraceconfig.json with us?


6. Do you also have a pvrtrace.cfg in the same location? The recorder will search for the new style config first (pvrtraceconfig.json), but will fall back to pvrtrace.cfg. This could explain why the behaviour changes when your pvrtraceconfig.json is deleted

Thanks,
Joe

Hi,



Thanks for the information. We have some follow up questions:

1. Are you using PVRHub to install the recorder libraries, or have you compiled them into your APK?


2. We can't see any EGL calls in your logs. Have you removed them?


3. Are you calling EGL from native, or from Java? There's a known limitation where we cannot record EGL calls from Java if the recorder libraries are built into your APK

Thanks,
Joe

[mercutiogeek-2]

1. Compiled in to my APK. Somewhat related note, I wasn’t able to install the libs with PVRHub, my device is rooted and normally when an application requests root access I get a popup to confirm authorization but I don’t get one for PVRHub. PVRHub simply informs me it couldn’t get root access and I didn’t find a way to grant authorization without the app first making the request.
   
   2/3. The only EGL calls in the project are in Java, no particular reason, that’s just how the sample project I built off of worked.
   

[JoeDavis]

Are you running SuperSU or a similar application on your device? PVRHub should cause a dialog to popup and confirm that you’re allowing the app to have root access. If this isn’t working, you should be able to configure application permissions within SuperSU. As an alternative, you can launch the PVRHubDaemon from a root terminal to enable PVRHub to execute commands as root. Here’s an ADB command for this:

adb shell su -c ‘/data/data/com.powervr.PVRHub/bin/PVRHubDaemon’&



As you’re using EGL through Java, you will have to use PVRHub to install the recorder libraries to the system. Alternatively, you can modify your application to issue all EGL calls from native, which will allow the APK recorder library packaging approach to work.



Cheers,

Joe

[mercutiogeek-2]

Cyanogenmod uses an app called Superuser, it is supposed to work as you described where when I run PVRHub I get a popup to confirm root access. A little research indicated that SuperSU will play nice with cyanogenmod so I installed that but same results, when I ran PVRHub I didn’t get a popup requesting access. I then tried running the Daemon and that worked (I had tried running it previously from the adb shell without success but that is likely due to my unfamiliarity with adb/linux). With the Daemon running PVRHub was able to install the libs and that seems to have solved my issue. My app now runs and it looks like I’m getting full trace logs



Thanks for your help Joe!

[JoeDavis]

No problem. Glad to hear the issue is solved



Joe

[mercutiogeek-2]

Dear god. Now that the libs are installed the phone has become basically unusable. Is that normal? How do I uninstall the libs?

[JoeDavis]

If the entire system feels sluggish, it may be the case that the recorder libraries are capturing every process (the splash screen, launcher etc.). On KitKat devices, this suggests that the config’s Exclude list is empty or missing system processes.



You can restore your device using PVRHubDaemon with this command:

adb shell su -c ‘/data/data/com.powervr.PVRHub/bin/PVRHubDaemon -r’

[mercutiogeek-2]

Thanks Joe, it was an issue with the exclusion list.

[mercutiogeek-2]

Just when I thought I was good…



I ran PVRHubDaemon -r to restore my device. It failed because it couldn’t find a .so. I then tried reinstalling the libs with PVRHub and now the phone is in an infinite boot cycle. Is there a way to manually restore the phone short of wiping it?

[JoeDavis]

Did you run PVRHubDaemon from a root terminal session, or use the command I mentioned before to execute as root on the target with adb?



Appendix A of the PVRHub manual explains how the daemon works, what options are available and how it modifies the file system. As discussed there, you can execute the daemon with the ‘-g’ flag to generate a report of the system status.

adb shell su -c '/data/data/com.powervr.PVRHub/bin/PVRHubDaemon -g’

If you can send us this report (either through the forum or as a support ticket), we can help you investigate the cause of the problem. It may be the case that the Cyanogen file system is for some reason different than vanilla Android builds we’ve tested.
