> not sure about Intel

I don't know about Arc, but Intel has historically probably been the most open with their GPU docs. AMD's is (while laudable, particularly compared to Nvidia) unfortunately a bit of a autogenned dump without context. Where as Intel's is closer to what I expect out of decent SoC documentation; it'll be about half prose explaining the why(!!), and half the autogenned tables of registers and opcode formats.

AMD's approach seems to be documentation in the style you describe plus employed FOSS developers who get access to internal people, simulators, possibly even source code. Makes it annoying for externals to try to contribute code, but the drivers are good.
