I’m trying to use hardware rendering on my Jetson AGX Orin device, and I’ve encountered some issues:
- I noticed that the kernel has loaded
tegra_drminstead ofnvidia_drm, but my environment contains bothnvidia-drm.koandnvidia-modeset.ko. Are these kernel modules still needed to be loaded? - The information from executing
lsmodis as follows; are there any kernel modules that have not been loaded?
root@p3737-0000-p3701-0005:/sys/module# lsmod

- I find it difficult to locate resources related to Tegra. Is there an introduction to the graphics framework and components associated with Tegra? Can I get some help?
