They've done the userspace bringup for linux since apple silicon servers allegedly exist. The drivers exist already so just throwing the device tree over the wall can't be that hard. Nobody is asking for systemready/UEFI or mainline linux.

I suspect that they might be changing their mind about upstreaming?

PureDarwin doesn't work on any of the M-series machines, and according to the Github commit log, hasn't been updated since 2024.

Which doesn't even boot on modern Apple hardware without all the closed source bits...
