AM5728: QtwebEngine segmentation fault

Hello Andy,

In PSDK 6.2, please confirm if you have made the changes mentioned in the following page. Also, please share the crash logs that you are observing.

Regards,
Krunal

Hello Krunal,

I am not sure, if you catch what I did. I will try to summarize what I did again.

Current version (DDK, based on linux kernel 4.4.113 + old OpenGL) is working as expected. I had to fix only missing "eglGetProcAddress" in QtWebEngine.

First target (PSDK6.1, linux 4.19.59 + new OpenGL) has the same egl address issue as previous version. So I have applied the patch also on this version. My browser application can access pages like google, but it crash on internal. I've just received a Segmentation fault on this page.

Last target (PSDK6.3, linux 4.19.73 + newest OpenGL) was also not working. Yes, I saw that eglfs raw accessing was dropped. So I have re-configure QT to use the new eglfs_kms method.

- enabled "gbm kms" QTbase options

- export QT_QPA_EGLFS_KMS_CONFIG=/etc/qt5/eglfs_kms_cfg.json
- export QT_QPA_EGLFS_INTEGRATION=eglfs_kms
- export QT_QPA_EGLFS_ALWAYS_SET_MODE=1

- set eglfs_kms_cfg.json

{
  "device": "/dev/dri/card0",
  "hwcursor": false,
  "pbuffers": true,
  "outputs": [
    {
      "name": "VGA1",
      "mode": "off"
    }
  ]
}

My application can run after reconfiguration as before with still failing Segmentation error.

I am still using my "egl address fix". Should I now remove it, but I don't think so...?
Is there any special config what I need to configure?
I think, it doesn't mater if I am using PSDK6.3 or not. Because it's still failing on the same error.

Andy

Hi Andy,

I am discussing the above issue with our developers and I will get back to you in 24 hours. Also, are you observing any issues with the below test:

root@am57xx-evm:~# /etc/init.d/weston stop 
root@am57xx-evm:~# /usr/share/qt5/examples/webenginewidgets/simplebrowser/simplebrowser --no-sandbox -platform eglf

Regards,
Krunal

Hello Krunal,

I have tested your commands.

root@am57xx-evm:~# /etc/init.d/weston stop 
root@am57xx-evm:~# /usr/share/qt5/examples/webenginewidgets/simplebrowser/simplebrowser --no-sandbox -platform eglf

I am not using weston, so I don't need to stop it.

I have built an Qt simplebrowser and quicknanobrowser too. Both of browsers have the same segmentation results on the internal webpage. As I said, other pages are fine.

Anyway simplebrowser has printed some EGLFS warnings during starting-up:

Hi Andy,

I have replicated the issue on my side and I am working with our developers to find the root cause.

Regards,
Krunal

Hi Andy,

I just wanted to clarify that on our setup, we see do not see the seg. fault and here is our test log:

root@am57xx-evm:~# /usr/share/qt5/examples/webenginewidgets/simplebrowser/simplebrowser --no-sandbox www.ti.com -platform eglfs
No modes available for output "HDMI1"
Unable to query physical screen size, defaulting to 100 dpi.
To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).
Cannot find EGLConfig, returning null config

I am wondering if you are using the default TI PSDK6.2 and if you have modified anything from the default SDK.

Regards,
Krunal

Hi Andy,

Based on my discussion with our developer, “libGLESv2.so.2” is actually part of Mesa3D and it is open source. The binaries have debug symbols and in the build folder, there should be a package called "ti-sgx-ddk-um-dbg_*.ipk" and it has the symbols for libGLESv2.so.2. Could you please try running your application with the debug symbols?

Regards,
Krunal

Hello Krunal,

I didn't say, that I have a fully PSDK6.2 version installed on my machine. I am just using PSDK changes on my revision. But generally speaking, I have PSDK running.

I can try to prepare for you a webpage, where you can test it on your side.

Regarding to "ti-sgx-ddk-um-dbg_1.17.4948957-r34.ipk" thank you for pointing this out. I can try to use libraries from this package a give a feedback.

Thank you,

Andy

Hello Krunal,

I have tested a browser application with debug package, what have you mentioned.

Backtrace stopped: previous frame identical to this frame (corrupt stack?)

Anyway there are missing debug symbols for "libGLESv2_PVR_MESA.so".

Regarding to testing webpage, I will send this "local webpage" over private mail from other collage.

Hi Andy,

The SEGV in malloc is usually an indication of heap corruption issue. I am wondering if you could please use valgrind, AddressSanitizer, or efence to track down who is causing the initial corruption.

Regards,
Krunal

Hello Krunal,

Valgrind using is not possible, due to not enough memory on the embedded target. Regarding to "AddressSanitizer", looks like, that I need to re-compile the whole QT with "-address-sanitizer". I am not really sure, what will happen, if whole QT will has this option enabled.

//EDIT:
I have used valgrind on simplebrowser and quicknanobrowser. Both of them failed on libfontconfig library. It doesn't matter which page I am trying to access, including a good one. So there should be something different.

I have also tried to use valgrind on my application. I have seen, that driver was trying to draw a webpage and then it crashed. But I think, a log is unusable...

valgrind: ../../valgrind-3.14.0/coregrind/m_mallocfree.c:307 (get_bszB_as_is): Assertion 'bszB_lo == bszB_hi' failed.
valgrind: Heap block lo/hi size mismatch: lo = 1280068684, hi = 1516175466.
This is probably caused by your program erroneously writing past the
end of a heap block and corrupting heap metadata.  If you fix any
invalid writes reported by Memcheck, this assertion failure will
probably go away.  Please try that before reporting this as a bug.

Regarding to testing suite. Did you already receive the "testing webpage" from your collage?

Regards,
Andy

Hi Andy,

I am working with Frank on downloading the test case. Also, there is a bug with the GPU driver and I have shared the updated binaries with Frank. I am wondering if you could please update those binaries in the "rootfs" folder and re-run your test. 

Regards,
Krunal 

Hello Krunal,

I have tested your driver. This is amazing, everything is working as expected. I have tested simplebrowser, quicknanobrowser and also the most important my application. All of them are working as well. (Do you need some logs there?)

How did you find it?
What was the problem there?
Could you please provide an official fix in repository?

Regards,
Andy

Hello Krunal,

Today I have created a clean build for my machine. I have flashed the FW and copied your testing OpenGL driver to device. But it's not working...

Unable to query physical screen size, defaulting to 100 dpi.

I think, the main difference between "working" and not "working" solution is, that there are only stripped libraries. (For debug purposes I have used full QT and glibc libraries).

Regards,
Andy

Hi Andy,

Could you please explain what you meant by "there are only stripped libraries"? By default, the libglslcompiler.so should be included in the "/usr/lib" directory.

Krunal

I mean, that there aren't any libraries with debug symbols like before. Previously I have copied them a glibc, fontconfig, qt ... and some other libraries with debug symbols to obtain a full dump. Now there is a general file system. I have just extracted there an archive, which you gave me as before.

/EDIT:

I have replace the failing library (libglslcompiler.so.1.17.4948957) with previous version(um- 2a2e5bb090ced870d73ed4edbc54793e952cc6d8) and it worked. So please provide also a new version of libglslcompiler.

Thank you,
Andy
