IGX Developer Kit can be configured in following modes:
iGPU mode– This mode is used when not using any discrete GPU with the IGX Orin Developer Kit. This mode uses the NVIDIA Ampere integrated GPU on the NVIDIA IGX Orin module.
dGPU mode– This mode is used when using an additional discrete GPU with IGX Orin Developer Kit. In this mode compute is leveraged from both NVIDIA Ampere integrated GPU on the NVIDIA IGX Orin module and the discrete GPU connected to a PCIe slot.
Note
At the time of publication of this document, iGPU and dGPU drivers cannot both be loaded at once.
