STRUCT DRM_DP_AUX_CEC(9)

✨ struct drm_dp_aux_cec(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 — we're talking about struct drm_dp_aux_cec(9) today and honestly? it's giving "small struct, big responsibilities." no cap.

🦋 NAME 🦋

struct drm_dp_aux_cec — DisplayPort CEC-Tunneling-over-AUX. that's the whole vibe. it tunnels CEC over AUX. iconic behavior fr fr 💅

🌸 SYNOPSIS 🌸

here's the struct in all its glory, character for character, don't touch anything:

struct drm_dp_aux_cec {
    struct mutex lock;
    struct cec_adapter *adap;
    struct drm_connector *connector;
    struct delayed_work unregister_work;
 };

🎀 Members 🎀

okay so let's meet the squad, one member at a time 🫶

• lock — a mutex that protects this struct. it's literally the bouncer at the door of the struct. nobody in without the lock, periodt 🔒
• adap — the CEC adapter for CEC-Tunneling-over-AUX support. this is the main character right here 👑 the whole reason this struct exists.
• connector — the connector this CEC adapter is associated with. like, whose connector is this anyway? this one. that one. the association is real 💜
• unregister_work — unregisters the CEC adapter. it's a delayed_work, so it's the "we'll deal with this later" member of the group chat 😭🙈
