We are developing a custom carrier board for the Jetson AGX Xavier. We are wondering whether the AGX supports “bifurcating” any of the PCI lanes, so that we could (for example) treat a single x4 lane, as a pair of x2 lanes dedicated to two separate devices (two SSDs, or an SSD and a camera, etc.). Please let us know if the AGX hardware supports this, and what if any madness might be needed on the kernel side. Thanks!
