drm_add_edid_modes(9)

✨ drm_add_edid_modes ✨

okay so bestie, welcome to the drm_add_edid_modes(9) page 💖 this is one of those Kernel API Manual entries, and it's all about pulling display modes out of EDID data if there's any to be found. let's get into it 🎀

---

🌸 SYNOPSIS 🌸

int drm_add_edid_modes (struct drm_connector *connector , struct edid
*edid );

like. that's the whole vibe. one call, two args, go off 👑

---

🦋 ARGUMENTS 🦋

• connector — the connector we're probing, iykyk 🔍
• edid — the EDID data itself, the whole point of the operation 💅

---

💜 DESCRIPTION 💜

so what this does is, it adds the specified modes to the connector's mode list ✨ and yes that's the main character moment, but it's not the only thing — it also fills out the drm_display_info structure and the ELD in connector with any information that can be derived from the edid. two-for-one, we love to see it 🫶

⚠️ okay major heads up bestie — this function is deprecated. use drm_edid_connector_add_modes instead. no cap, it's the replacement 💀

---

⭐ RETURN ⭐

it returns the number of modes added — or 0 if we couldn't find any 😭 (nothing to slay, unfortunately)
