tb_domain_d...t_pcie_paths(9)

📦 version 7.3.1, in nixpkgs unstable

💅 tb_domain_disconnect_pcie_paths(9) — aka the "bye-bye PCIe paths" era 💅

okay so first things first, bestie: this little beauty lives in the Kernel API Manual (that's the manual name, noted ✨), and the page title is the gloriously truncated tb_domain_d...t_pcie_paths(9) — which is literally just tb_domain_disconnect_pcie_paths wearing a tiny tiny trenchcoat. iykyk 🫶

🌸 NAME 🌸

tb_domain_disconnect_pcie_paths — the function that disconnects all the PCIe paths. like, all of them. every last one. no cap 💅

✨ SYNOPSIS ✨

int tb_domain_disconnect_pcie_paths (struct tb *tb );

that's it. that's the whole vibe. one arg, one int, one mission 🎀

🦋 ARGUMENTS 🦋

  • tb — the domain whose PCIe paths you're about to disconnect. like, hand her the domain and she'll yeet the paths for you. main character energy honestly 🌈

💖 DESCRIPTION 💖

okay so listen. this function needs to be called in preparation for an NVM upgrade of the host controller. needs. it's not optional, it's not a vibe suggestion, it's a requirement, periodt 🗣️

and what does she actually do? she makes sure all PCIe paths are disconnected. all of them. she is thorough. she is iconic. she does not leave a single path behind 😭✨

fr fr, think of it as the pre-NVM-upgrade ritual: clear the paths first, then do the upgrade. skipping this is giving chaos, not giving slay 💀

🔥 RETURN 🔥

  • 0 on success — we love a clean victory 🎉
  • a negative errno in case of error — because sometimes the universe says no 🙈

okay that's the page!! it's sourced from ./drivers/thunderbolt, dated October 2026, and it's rocking tb_domain_d...t_pcie_paths(9) as its header — go forth and disconnect those paths, bestie, you got this 💅🎀⭐
