Jetson-xavier-nx GPU-CPU communication

Jetson-xavier-nx have 48 Tensor Core GPU and ARM®v8.2 64 bits CPU, What I want to find out is what is the way the CPU and GPU communicate with each other on this board? And , what hardware interface does NVIDIA use to connect GPU-CPU ( I guess … pcie )?


Jetson is an iGPU (integrated GPU) system.
The GPU is on the chip rather than connecting with PCIe.


An alternate way to say the same thing: PCIe discovery functions won’t work on this. The GPU is directly wired to the memory controller.
