Wait, one can write udev rules for connectors and stuff? How? What can they do?

I was using it to generate user-friendly device names for the mst aux implementation: https://patchwork.freedesktop.org/patch/315900/?series=63237&rev=2

Hi,

what is that device node used for?

Are the "by-path" symlinks to help a display server associate the right device node with the right DRM KMS connector resource?

The patch commit message did not explain what the names are actually used for.

Thanks, pq
