Is there a list of all supported video modes of the nvidia driver?
So far I’ve tried
cat /sys/class/graphics/fb0/modes - this gives a list of modes supported by the connected display, but I want a complete list of all supported modes
I also enabled debugging in xorg.conf, and the log shows that various modes are rejected by the driver. I would like a complete list of supported modes from the driver.
There is no completed supported modes. The driver would not tell this info.
You can check the l4t developer guide to see what are supported.
https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fsoftware_features_tx2_tx2i.html%23wwpID0E0PB0HA
And the driver only accepts the modes from your monitor EDID. Adding a mode manually is not acceptable.
We are using a custom EDID in the devicetree, so we are able to add modes by editing the EDID.
Based on the link you provided, the driver supports all formats that are compatible with HDMI 1.4 and HDMI 2.0, can you confirm this? Even interlaced modes.
No, no tegra device supports interlaced mode yet.
