    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).

      There was a recent proposal to make use of ACPI on ARM

        There is also ARM SystemReady which is an existing spec for this mainly intended for servers. But it’s not being followed well.

        It’s crazy to need a million device trees on server or laptop class devices.
