hardware.nvidia.prime.amdgpuBusId
NixOS option
Bus ID of the AMD APU. You can find it using lspci; for example if lspci shows the AMD APU at “0001:02:03.4”, set this option to “PCI:2@1:3:4”. lspci might omit the PCI domain (0001 in above example) if it is zero. In which case, use “@0” instead. Please be aware that this option takes decimal address while lspci reports hexadecimal address. So for device at domain “10000”, use “@65536”.
type: string matching the pattern ([[:print:]]+:[0-9]{1,3}(@[0-9]{1,10})?:[0-9]{1,2}:[0-9])?Default
