No such luck for the M1, but we at least have the fact that it's a legacy-free architecture, comes from the mobile space (where GPUs are historically less insane than PC ones), and I trust their engineers a bit more than AMD or Nvidia ones :-)

The other big open source fully reverse engineered GPU driver project is Nouveau, which has shown that this is possible. Unfortunately they've been *heavily* screwed over by Nvidia (except on Tegra, the only place they've helped out at all).

The fact that Apple allows this in their secureboot policy is critical. Linux ports to game consoles / iPhones / etc are all fun and games, but you're always at the mercy of exploits, and the resulting cat and mouse game.

That means all effort is wasted unless exploits keep up, and regular users would never want to do this and severely limit their access to official upgrades and such. But this isn't an issue with M1 macs.

Of course there are downsides (security-wise) to downgrading your secureboot policy to run Linux, but nothing that would be worse than any old x86 machine with no serious secureboot anyway, so that's hardly a problem for the kind of people who'd want to boot Linux.

More importantly, Apple isn't going to go off suing people for working on this project. While reverse engineering macOS drivers may be legally questionable in some jurisdictions, it's perfectly legal in others, and so is getting the binaries (any mac owner can do it).

So what do you think? Is this something you'd actually throw money at? If there is enough interest that this might succeed, I'll open up a Patreon. Obviously all development would be public and open source.
