No, Eric wrote the open source driver for the GPU. There was actually quite a lot of effort invested into VC4 and that's why we still have it. But this is all software. [0] The actual HW didn't change much and the reason is because they got all fired. [1][2] I will give you a few links but this happened in 2014/2015 so it's not so easy to find a lot of relevant things (James who commented in the forum worked for them): [0] https://www.raspberrypi.org/forums/viewtopic.php?p=846710&sid=7e97844c1dcf5c7c80c890ab31fa96de#p846710 https://www.raspberrypi.org/forums/viewtopic.php?p=846710&si...

Edit: Back then I was a bit involved into QPU programming with the assembler which was written based on the open source documentation of the VC4. That's why I have seen all this discussion. [3] I doubt that Broadcom has done much more then maintenance on the GPU IP in the last few years because Raspberry Pi are their only customers.
