...ion if it detects Windows 8 and newer. Have you checked
if that's the case?
Then you can call _DSM only if it is supported and otherwise expect the
parent device's power resources to turn off power when runtime
suspended.

This is needed to avoid the regression reported in the cover letter, but
also allows pre-2015 systems to (still) have the D3cold possibility.
Out of curiosity I looked up an pre-2015 laptop (found Acer V5-573G,
apparently from November 2013, Windows 8.1) and extracted the ACPI
tables from the BIOS images. BIOS 2.28 (2014/05/13) introduces support
for power resources on the parent devicea(\_SB.PCI0.PEG0._PR3 and a
related NVP3 device) when _OSI("Windows 2013") is true. (This is added

...er it is working and do not bother removing legacy functions. The
Acer case below seems exceptional.
I suggested the no_d3cold check such that DSM can still be called even
though the runtime PM on the PCIe port does nothing.

...right to poke parent device's fields directly.
What if you just check if it has the method like:
bool no_dsm = acpi_has_method(parent_adev->handle, "_PR3");
That should follow what Windows is doing.
