On the board is using linux & qnx as operating system,QNX is running on a Hypervisor.and not sure the linux is native or running on hypervisor.

Here is the questions:
What is the difference between Drive OS and Jetpack?
(1),Drive OS use hypervisor? - I read the dts file like host_1 { } from DriveOS sdk package,but this is still exist in Jetpack sdk package.
(2),From the libs in Drive OS about NvMuiltMedia,dose Nvidia use V4L2 struct to get the image?
(3),How the Drive OS sync the images from muti-cameras?

Thanks
