The article says "A real fix depends on Nvidia, specifically on porting the platform controller’s power management logic into its Linux driver, which would effectively turn the laptop into a portable version of the DGX Spark."

My point is that's not Nvidia's responsibility. The article itself admits the laptop "ships with Windows on ARM", so support for another OS shouldn't be expected, even if NVIDIA supports other platforms and other product lines differently.

These aren't "other product lines" though. They are RTX and Spark SOC products that do support Linux as a first-class citizen with all of their hardware. The RTX Spark is the outlier, and the breakage is not on the GPU product, but the SOC devicetree drivers. This is only a problem because Nvidia avoided standard Windows power management a-la ACPI/UEFI, and has to port the remainder to Linux by hand. Non-laptop products like the DGX Spark support this via UEFI natively.

There are OEMs that refuse this responsibility. If that's the vindication you wanted, there you go. This specific issue is not a catastrophic oversight though.
