Sorry I didn't get round to answering earlier. I have taken a look at your code (the Mesa part), and on the whole it looks like something we could make good use of too, except that we would want to be producing a stream of something closer to OpenGL which we could send over our existing proxying mechanisms. Since you put the client and server code conveniently close to each other in your clone of the Mesa repository, my idea would be to add an build-time option to do this by pulling the server-side code into the Gallium driver too - is that something you could live with if I wrote code for it? My tendency is to output a white-listed subset of OpenGL as a text stream which a custom winsys back-end could send into a DRM driver. Regarding your comments on the safety of passing OpenGL through, isn't a major part of the risk in the shader code anyway, which we can't really not pass through either way?<br>
<br>
I would probably not be able to get on to writing the code I mentioned above immediately either, as this will not make sense without a proper DRM driver which we currently don't have, and which would be my first target. Since this is my first proper visit to that part of the kernel code I will probably take a little bit more time for it that you would.<br>
