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From what I can tell, the Elite SoCs are a lot less outdated-semi-proprietary-Linux-fork-y than many other Qualcomm chips.

That means nothing for the community who may need or want to fix and patch issues on their own. Instead we're beholden to Qualcomm to fix major issues on an OS it may or may not care about supporting. It also excludes other open source operating systems such as the BSD's who have to then reverse engineer the undocumented Linux drivers.

A better question: can a small company like Framework or even MNT Research build and support an open laptop around this chip?

Framework doesn't even develop their own firmware; most of the engineering in PCs is done by Intel/AMD/ODMs/IBVs. The whole ecosystem is based on vendor support not datasheets.

Firmware is not preventing Framework or anyone from offering a repairable laptop. Firmware also doesn't matter once the kernel is loaded. We need the datasheets.
