Good day! My friend - also a G505S coreboot'er! - is using the "G505S discrete GPU" not-merged-yet patch series from https://review.coreboot.org/c/coreboot/+/58745 , which successfully get a G505S discrete GPU working (). However, trying to get a better GPU performance, he's connected an external discrete AMD RX470 GPU to this laptop's MiniPCIe port (originally meant for WiFi module) using a MiniPCIe-to-PCIe adapter. So his G505S has three GPUs: internal integrated HD-8650G, internal discrete (HD-8570M or R5-M230) and external discrete.
For unknown reasons, G505S coreboot choses this external discrete GPU as a primary video output, ignoring the laptop's screen. Please, could you advise where in coreboot we could set up the default video output priority for this AMD AGESA board? Any idea where to dig?
Best regards, Ivan
