You can not run Linux on IPhone 12. Neither you can run Linux on Snapdragon X laptops in any meaningful way, today. While there was some Linux demos before Computex, there was no Linux demos on Computex, and people presenting the laptops were declining to comment about Linux.
"TUXEDO Computers showcased a prototype of its ARM notebook at the Computex trade fair in Taiwan. This prototype is part of the company’s ongoing project, internally dubbed “Drako,” aiming to port TUXEDO OS with KDE Plasma to the ARM platform. The development is currently in the alpha stage, with some drivers still pending. TUXEDO is optimistic about resolving these issues with the next two kernel versions. While a release date is not yet set, the possibility of an ARM notebook under Christmas trees in 2024 is tantalizingly close."
"Qualcomm has been working to ensure good Linux support for the Snapdragon X Elite high-end laptop SoC. That work is still ongoing but the initial bits are already in the mainline kernel while other optimizations and other features remain in the works. So far for the Snapdragon X Elite has been many vendors showing off Microsoft Windows based laptops but it looks like from at least TUXEDO Computers there will be a Linux-focused laptop using this ARM64 chip."
When you rely on volunteers blindly reverse engineering Apple hardware you're never going to reach a level of support and stability that meets mission-critical requirements. It's a hobbyist solution.

It's amusing because Linux started as a hobbyist solution. I think the results will speak for themselves. Asahi Linux is quite usable with some limitations. Corporate support for Linux doesn't guarantee usability based on past efforts.
