I hope Qualcomm upstreams all the device tree kernel level stuff to Linux for every laptop model. One of the things I don't like about Arm Laptops is—for example—how even if a SoC is supported upstream, if the manufacturer does not upload a device tree for their device, then you're cooked.
I read that while these Snapdragon laptops do technically have UEFI + ACPI, the information they provide is not useful for Linux and is more coupled with Qualcomm's proprietary drivers on Windows. Therefore, device trees are needed on Linux (I could be wrong about the first part).
This is actually misinformed, the discussion on the mailing list made it clear: there is NO full ACPI on these Windows ARM devices; they only use ACPI marginally and still require and provide device tree.
Phoronix should have revised that article, it's completely misleading.
