drm_connector_list_update(9)

✨ drm_connector_list_update ✨

Okay bestie, welcome to the Kernel API Manual page for drm_connector_list_update(9) — the function that freshens up a connector’s mode list. This is highkey a mode-list glow-up, not a full validation spa day. 💅

💖 NAME 💖

drm_connector_list_update — update the mode list for the connector. That’s the whole name, no cap.

🌸 SYNOPSIS 🌸

void drm_connector_list_update (struct drm_connector *connector );

🫶 ARGUMENTS 🫶

• connector — the connector to update. Yes, that’s the only argument, and it’s literally the connector getting its mode-list moment. ✨

🦋 DESCRIPTION 🦋

So here’s the tea: this moves the modes from the connector’s probed_modes list over to the actual mode list. It compares the probed mode against the current list and only adds the different/new modes — no duplicates sneaking into the group chat. 🔥

Big important vibe check though: this is just a helper function. It doesn’t validate any modes itself, and it also doesn’t prune any invalid modes. Callers need to do that themselves. So don’t expect this function to clean up your messy mode list for you — it’s giving “I move things, you do the vetting.” 💀
