I'm having issues running a Qt/OpenGL application on a TI AM37xx EVM equipped with the SGX530 chip. I'm seeing warnings suggesting that some features are either broken or unimplemented on that chip.
To better explain the problem, here is the relevant code where the GL context is made current:
As you can see, Qt is explicitly enabling workarounds for:
* the need of clearing *all* client buffers (color, depth, stencil as well?) before drawing a frame;
* unrealiable behaviour of glTexSubImage2D on textures bigger than 1024x1024;
* unrealiable behaviour reading from FBO's: from what I have understood, this also seems to make impossible for the driver to implement cursor drawing in hardware without redrawing the whole frame each time the cursor moves.
Are you aware of any of the above problems? And, if so, will a later revision of hardware/driver become available to avoid doing these workarounds?
Thanks in advance!
