GLES Vivante GPU in i.MX6 doesn't support glMapBuffer

[kimlim]

I tried to make use of glMapBuffer in i.mx6 to create a read write buffer[1] but found that glMapBuffer is not implemented by the GLES of Vivante GPU.

Any way we could create a read write buffer to allow bi-directional GPU-Host communication?

Hi Kim,

From the OpenGL ES2 and ES3 spec and its header file (http://www.khronos.org/registry/gles/api/3.0/gl3.h) and,

the glMapBuffer is not supported. Instead, the glMapBufferRange is supported.
