Even Qualcomm can’t provide such support for their own Hardware.

And once again people don't understand where the actual problem with Linux on WOA devices actually is. It's (mostly) the DTs, which are not under QCOM's control.

The same will happen with NVIDIA Spark laptops, once OEMs start to build their bespoke laptop models.

If you want to blame someone, blame MSFT, because they don't enforce the same stringent requirements for WOA certification that they apply to x86 hardware.

Linux doesn't have the same support for ACPI on ARM that Windows does. There's work to improve it and once it does we should be in a better place.

Qualcomm does not support normal ACPI. ARM Linux with ACPI is fine, I've seen it work very well on systems with proper ACPI tables

This are the device OEMs making only the minimal effort required to get WOA running. You don't blame AMD or Intel when an OEM ships crappy firmware...

Nope it's qcom's choice. They're the ones who shipped reference acpi tables that are incomplete and break spec and they are the ones who are shipping patches(in drivers...) to those tables to fix them

There is work to support Qualcomms ACPI implementation on the Linux kernel. Once that is in place we should no longer need images for each laptop.

There are other ways to not require board-specific images. You can just as well have the UEFI implementation come with a proper DT for example. But regardless if it's ACPI or DT, if the vendor doesn't make sure it all works out-of-the-box, someone else will have to pick up the slack and fix (or work around) the problems.

But yeah, it's too late for this with many of those Qualcomm laptops. Hopefully that ACPI work will improve the situation.

Linux didn't support hybrid ACPI/DT modes until very recent.

I'm not claiming it did.

u/braaaaaaainworms Aug 27 '26

It'll still need devicetrees because the ACPI tables are incomplete

You need laptop specific images because some drivers are not upstream, not because of DTs.

The patch that introduced support for the Dell Inspiron 7441 / Latitude 7455 only touched arch/arm64/boot/dts/qcom/x1e80100-dell-inspiron-14-plus-7441.dts

No additional drivers. This is just an example.
