💅 struct typec_cable_ops(9) — the Kernel API Manual, bestie edition 🎀

okay so you're in the Kernel API Manual and the main character of this page is struct typec_cable_ops — it's literally the Cable alternate mode operations vector. yes queen, a whole vector of cable ops. let's get into it ✨

---

🌸 NAME 🌸

struct typec_cable_ops — the Cable alternate mode operations vector, aka the lil bundle of function pointers your cable's alt mode rolls with 💖

---

✨ SYNOPSIS ✨

like, here's the whole struct, verbatim, no notes:

struct typec_cable_ops {
    int (*enter)(struct typec_altmode *altmode, enum typec_plug_index
sop, u32 *vdo);
    int (*exit)(struct typec_altmode *altmode, enum typec_plug_index
sop);
    int (*vdm)(struct typec_altmode *altmode, enum typec_plug_index sop,
const u32 hdr, const u32 *vdo, int cnt);
 };

---

🦋 Members 🦋

bestie these are the three members and they're each kind of iconic in their own way:

• enter — the operations to be executed with the Enter Mode Command 🫶 like, going in.
• exit — the operations to be executed with the Exit Mode Command 💀 like, leaving. no dramatic goodbye tho, it's just a callback.
• vdm — the callback for SVID specific commands 🔥 the SVID-specific one, periodt.
