The router has no lspci, so its GeminiLake chip came up as 'Intel GPU 3185' beside the identical chip's 'Intel UHD Graphics 600' on hamtv. A trimmed pci.ids — the graphics devices of Intel, AMD and NVIDIA, and the virtual GPUs, 115 KB — rides in the binary and is consulted first; lspci is the fallback for a card newer than the table. scripts/pci-ids-gpu.sh regenerates it from the hub's copy.
