Eh, I've heard the same thing form people I trust, and I'm not the Apple news version of deep throat or something. It's simply not a very well kept secret.
Although part of me wonders if the code will flow the other way. Now that marcan has put in the elbow grease to upstream concepts like 16KB pages, the non standard ordering for regular MMIO and PCI on Apple Silicon, etc, will Apple embrace those in their custom distro to avoid having so much un-upstreamed code? We'll probably never find out, but it's fun to think about.
16kB pages weren't too hard to get running before, iirc, it's just that most devices people care about went to 64kB.
Generally linux is happy unless you try to make pages smaller than 4kB,then all sorts of hell break lose in VFS
Linux is generally fine with 16K pages; userspace programs often are not.
