SubjectRe: [Nouveau] [PATCH 1/7] Revert "ACPI / OSI: Add OEM _OSI string to enable dGPU direct output"
fyi: I decided to go for a different workaround to fix the runpm
issues observed with nvidia gpus with nouveau in the "pci: prevent
putting nvidia GPUs into lower device states on certain intel bridges"
thread

that's on the pci and pm mailing list. Maybe it makes sense to wait
for that to land before actually removing the ACPI workarounds here?
The workaround I had in this series didn't seem to be reliable enough,
so I ditched that approached.
