https://review.coreboot.org/c/coreboot/+/38743/1/src/northbridge/intel/haswe... PS1, Line 23: ShiftRight (_SB.PCI0.MCHC.DVEN, 3, Local0) : Return (And (Local0, 1))
Just to be clear, that's replace: […]
Confirmed that replacing both lines with just Return ((_SB.PCI0.MCHC.DVEN >> 3) & 0xf) works. Note the change to 0xf, I am testing this now to see if it makes dGPU work under Windows. If it does I'll post an updated commit with 0xf, and if not I'll post one as-is with just 1. This does work under Linux (Ubuntu 18.04.4 with 5.3.0-28 kernel, both Nouveau and Nvidia-Proprietary are able to render to this card, although Nouveau is noticeably slower than proprietary).
