How to mirror serial output ttyS0 to the HDMI /dev/dri/card0?

When I starting my single board computer, I can face the output from the UART, or even called /dev/ttyS0. I want to mirror everything to my HDMI port which is placed on /dev/dri/card0. How can I achieve that? Here I'm running the command drm_info. I'm using Ubuntu 24.04 LTS. >> drm_info [?2004l Node: /dev/dri/card0 ├───Driver: stm (STMicroelectronics SoC DRM) version 1.0.0 (20170330) │ ├───DRM_CLIENT_CAP_STEREO_3D supported │
