Does iMX6 support egl context sharing between multiple threads?

Hi all.

 

Currently I used Vivante OpenGLES 1.1 and EGL 1.4 library in i.MX6 platform, and I want to share egl context between two different threads.


Here is my implementation:

Thread 1:

mSharedContext = eglCreateContext( egl_display, egl_config, NULL, contextAttrbs);

... ...

Thread 2:

mContext = eglCreateContext( egl_display, egl_config, mSharedContext , contextAttrbs);

 

There was no error in Thread 1, but eglGetError() always returns EGL_BAD_MATCH when running eglCreateContext in Thread 2.

 

So I wonder Vivante OpenGLES 1.1 library in i.MX6 platform could support context sharing between multiple threads.

Any help is appreciated in advance.
