The Apple M1 SoC is by far the fastest ARM-based chip for the consumer market but Torvalds isn't interested unless Apple opens up. And that's an unlikely scenario:
In an exclusive interview, Torvalds expanded on why he can't see porting Linux to the M1-based Macs. "The main problem with the M1 for me is the GPU and other devices around it, because that's likely what would hold me off using it because it wouldn't have any Linux support unless Apple opens up."More details at ZD Net.
Apple has long had a love/hate relationship with open source. Apple's never been forthcoming with the hardware technical details that open-source developers need to make the most of their gear.
