I am aware that there has been alot of questions about using dedicated Nvidia or AMD GPUs with the Pi (I have asked a few of them). But ARM (mali core ) and Vivante among other companies appear to offer low-watt mobile GPUs that are equal to or slightly faster that the VideoCore 4 (VC4), and support OpenGL/OpenGL ES, Vulkan, and DirectX. Instead of gripping about the relativly poor performance of the VC4, is it theoreticaly possible to find a new working GPU and lisence the IP (Recompiled drivers or source code) to the Raspberry Pi Foundation to use in, say, Pi 4?
What are the actual issues with this? Other than drivers, will it theoreticaly be possible? For example, does a ARM Mali need a special port like PCIe x16 that is not on the Pi's CPU? (yes, yes, I know that the pi does not have any form of PCI on it, but it must have something like that, because it is connected to the VC4) Is it latency? Does the Pi not have enough RAM? Or Is it simply too expensive for the Pi Foundation?
I now have quite a bit of free time to research this and work on this, but I am only a hobby programmer with no technical training, so before I try to contact ARM or Vivante and waste my and their time, I want to see if there is one big show stopper before I start.
To be clear, my question is: Issues with PI and faster VC4 alternatives, just so that those people who bash me over the head for "not writing a prefect, cookie-cutter Stack-Exchange Question" might lay off this time, because somehow there is something wron with every single question I ask.
