💖 drm_bridge_edid_read(9) — like, the whole tea 💖

okay bestie, welcome to the Kernel API Manual ✨ this one's a lil function that goes and gets the EDID data of whatever display is plugged in. it's short, it's sweet, it's giving "small but mighty" 🎀

🌸 NAME 🌸

drm_bridge_edid_read — read the EDID data of the connected display 💅

✨ SYNOPSIS ✨

const struct drm_edid * drm_bridge_edid_read (struct drm_bridge *bridge
, struct drm_connector *connector );

like, that's the whole signature, no cap 🫶

🦋 ARGUMENTS 🦋

  • bridge — the bridge control structure 🌉 your main character, fr
  • connector — the connector to read EDID for 🔌 yes bestie, this one

💜 DESCRIPTION 💜

so here's the vibe check 👑 if the bridge supports output EDID retrieval — and it tells you that with the DRM_BRIDGE_OP_EDID bridge ops flag — then the function calls drm_bridge_funcs.edid_read to get the EDID and hands it right back to you 🎁 literally that simple.

if the bridge doesn't support it? yeah, it just returns NULL 🙈 no drama, no fuss.

⭐ RETURN ⭐

the retrieved EDID on success 💖 or NULL otherwise 💀
