Rendering using OpenGL ES 2.0/3.0 in a zero copy mode on MALI T628


I am looking for example / articles on how to perform updates to an Open GL ES texture (without using low Performing glTexSubImage2D approach) in a zero copy approach.

I am currently focused on odroid XU3 with MALI  T628 running ubuntu.

I studied and tried eglcreateImageKHR approach without success (I cannot create an eglImage: error EGL_BAD_PARAMETER is returned when using EGL_NATIVE_PIXMAP_KHRas a target).

I read that MALI driver has support for UMP data transfer, but I still need a reference to the inner buffer in a openGL ES texture.

Any help needed
