Snapdragon X2 Elite ARM Laptop CPU

Here's my big question: are there datasheets/programmers manuals available or is this yet another proprietary mess of a SoC that ships undocumented Linux drivers with binary blobs? No thanks.

I will not spend money on hardware no one can reliably patch or write drivers for. I also want other operating system maintainers to be able to write drivers and get booting.

I haven't dug deep, but it looks like Qualcomm has been working on merging code into the Linux kernel: https://www.phoronix.com/news/Qualcomm-X2-Elite-Linux-8EG5

With them only merging upstream now, it'll be a while before you can actually use Linux on these devices. You can build your own kernel from upstream, but it's probably a better idea to wait until Arch or Gentoo package the necessary pre-configured kernels.

From what I can tell, the Elite SoCs are a lot less outdated-semi-proprietary-Linux-fork-y than many other Qualcomm chips.
