I am using a TI Sitara AM3554 processor, which includes a SGX530 GPU.
As far as I know, OpenGL ES 2.0 does not support uniform buffer objects (UBO). However, when I retrieve the list of GL extensions which are supported by my processor, there’s an extension called “GL_IMG_uniform_buffer_object”. I can’t find any information about this extension in the “PowerVR Supported Extensions” document, and the SDK headers don’t include function prototypes for the respective functions.
What’s the story on this extension, and can I use it with the SGX530 GPU?
I’ve been told that the extension was exposed by mistake. The specification was never released and there may be bugs in the implementation. As the extension is unsupported, we would not recommend using it.
