Hi to all. I'm experimenting with running a https://www.zotac.com/us/product/graphics_card/geforce%C2%AE-gt-710-1gb-pcie-x-1 card on an Nvidia Jetson TX2 arm64 device. Possible? Linux kernel aarch64 5.6.10. Because Nvidia did not list drivers for this architecture, I'm experimenting with a nouveau driver. The Jetson TX2 has a default driver for the host1x framebuffer for output from the
