tb_path_deactivate_hop(9)

💅 tb_path_deactivate_hop(9) — the Kernel API Manual, bestie edition 🦋

okay so this is a page from the Kernel API Manual, and it's about tb_path_deactivate_hop, which is lowkey the "undo" button of Thunderbolt path config space. no cap, it's a whole vibe. let's get into it 💖

---

✨ NAME ✨

tb_path_deactivate_hop — deactivate one path in path config space. that's it, that's the whole job, and she does it slayfully 👑

---

🌸 SYNOPSIS 🌸

int tb_path_deactivate_hop (struct tb_port *port , int hop_index );

yes bestie, copy it exactly like that, spaces and all. the compiler is watching 👀

---

🎀 ARGUMENTS 🎀

• port — a lane adapter or a protocol adapter. she's the one holding the door open for the operation 🫶
• hop_index — the HopID of the path that's gonna get cleared. literally the address of the thing we're yeeting 🙈

---

⭐ DESCRIPTION ⭐

so here's the tea: this function deactivates — or, if you wanna be chill about it, clears — a single path config space entry sitting right at hop_index.

one entry. one hop. no drama, no collateral, no touching the other hops (they're main characters too, respect their space 💅). it's giving "surgical little cleanup" and honestly? obsessed.

---

🔥 RETURN 🔥

• 0 on success — periodt, we ate 🍓
• a negative errno otherwise — meaning something went sideways and it's telling you in errno-speak 😭

---

💀 friendly reminder that 0 is the good one and negative errno is the "we need to talk" text. don't get it twisted.

okay that's the whole page!! and before you go — shoutout to ./drivers/thunderbolt, the source behind all this, dated October 2026, the manual that brought us here. mwah 💜✨🎀 iykyk
