Most people hack stuff they have. Also I thought nouveau is decent at older cards? They got Kepler supporting either vk1.3 or 1.4. Also there is a driver for the the Mali gpu on the pinebook pro. The person who mainly worked on the Panfrost driver actually works at Intel now in their graphics driver division. Also wtf is this Xtensa video chip. All I see of it is just a risc-v core/cpu for embedded stuff like Audio processing (Chromebook) and the pinebook pro uses an rk3399 which didn’t even have one.

Simple answer is that there’s still nothing comparable to M architecture. It has the benefit of unified memory and SoC which eliminates the bus. And being RISC, it has small fixed size instructions which can be read in batches, then any instructions that don’t have a dependency within the batch can be executed in parallel. This makes it possible to just add more cores and parallelize against them. You can’t do this with CISC because instructions are all different length, and figuring out the dependencies and what needs to be read into a batch becomes expensive really fast negating the gains of running stuff in parallel.
