...hod that emulates at least
the "Optimus" interface for GUID a486d8f8-0bda-471b-a72b-6042a6b5bee0.
You probably lost interest here, but if you want to continue anyway this
is what allowed me to install the driver on the XPS 9560:
https://github.com/Lekensteyn/acpi-stuff/blob/master/d3test/fakedev.asl
If you adapt if for your environment, note:
- I have only tested this with the q35 machine type with an additional
ioh3420 root port. See the XPS956/boot-vm script.
- The \_SB.PCI0.SE0 device should match the root port:
cat /sys/bus/pci/devices/0000:00:1c.0/firmware_node/path
(the SE0 na...
