Hi Thomas thank you for your answer.


This is the question from the client:

The GPU 2D/3D acceleration is not working in the Yocto qte-in-use-image.  Looks like the "virtual/libgles2" and "-opengl es2 -openvg" are missing from imx6 in files qt4-embedded_4.8.4.bbappend and qt4-x11-free_4.8.4.bbappend, as shown below.
 
     DEPENDS_append_mx5 = " virtual/kernel virtual/libgles2"
     PACKAGE_ARCH_mx5 = "${MACHINE_ARCH}"
     QT_GLFLAGS_mx5 = "-opengl es2 -openvg"
     QT_CONFIG_FLAGS_append_mx5 = " -I${STAGING_KERNEL_DIR}/include/"
 
     DEPENDS_append_mx6 = " virtual/kernel"
     PACKAGE_ARCH_mx6 = "${MACHINE_ARCH}"
     QT_CONFIG_FLAGS_append_mx6 = " -I${STAGING_KERNEL_DIR}/include/"
 
Adding "virtual/libgles2" and "-opengl es2 -openvg" for the imx6 as below resulted in the attached build errors.
 
     DEPENDS_append_mx6 = " virtual/kernel virtual/libgles2"
     PACKAGE_ARCH_mx6 = "${MACHINE_ARCH}"
     QT_GLFLAGS_mx6 = "-opengl es2 -openvg"
     QT_CONFIG_FLAGS_append_mx6 = " -I${STAGING_KERNEL_DIR}/include/"
 
What is the correct way to enable GPU 2D/3D acceleration for imx6 in the Yocto qte-in-use-image?

In the log you can see that the EGL appears disabled. And OpenVG fails too.

>EGL (EGL/egl.h) disabled.

What GPU acceleration to you mean?
One doesn't simple 'enable GPU acceleration' :)

What does your application do, what do you want to achieve and what isn't working/isn't as fast as you expected?
"they report"? 'they'? 'report'?
