ETA: Sorry I was wrong. ACPI doesnt solve this*. Arm SystemReady SR/ES does and its why Ampere cpus can boot on linux on release without too much work.

Sadly its currently only used for iot/server stuff but hopefully it will eventually make its way to consumer tech. We need to raise awareness on this and pressure companies to commit to this standard.

*From what I read, WoA has full ACPI support but qcoms ACPI apis only work on Windows. [1 (ms link)][2]

~~Yeah its really unfortunate that most arm chips/devices use DTs instead of conforming to ACPI. However with ARM becoming more prominent on servers (and desktops), Im hoping this changes. There is now a push for ACPI on Arm since thats what companies running Arm on servers want. Ampere server cpus eg have ACPI support and arm now has docs on ACPI. I hope qualcomm is also forced to support ACPI. I think they will have to do it if they want to see their cpus being used in data centers and the like.~~
