prime.nvidiaBusId = lib.mkOption {
+
example = "PCI:1@0:0:0";
Bus ID of the NVIDIA GPU. You can find it using lspci; for example if lspci
+
shows the NVIDIA GPU 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".
prime.intelBusId = lib.mkOption {

example = "PCI:0@0:2:0";
Bus ID of the Intel GPU. You can find it using lspci; for example if lspci

+
lspci might omit the PCI domain (0001 in above example) if it is zero.
