tty_port_link_device(9)

📦 version 7.3.1, in nixpkgs unstable

okay so this is a page from the Kernel API Manual and it's literally about tty_port_link_device — linking a tty to a tty_port, bestie. it's giving matchmaker energy fr fr 💖

🌸 NAME 🌸

tty_port_link_device — link tty and tty_port

🎀 SYNOPSIS 🎀

void tty_port_link_device (struct tty_port *port , struct tty_driver
*directory , unsigned index );

wait no — copy it exactly, don't get cute with it:

void tty_port_link_device (struct tty_port *port , struct tty_driver
*driver , unsigned index );

there we go 💅

🦋 ARGUMENTS 🦋

  • port — the tty_port of the device. this is the port we're linking to, she's the main character here 👑
  • driver — the tty_driver for this device. yes it's called driver, no it's the tty_driver, keep up 🫶
  • index — the index of the tty. this is how we know which tty we're talking about ✨

💜 DESCRIPTION 💜

so what this does is provide the tty layer with a link from a tty (the one you specified by index, remember her?) to a tty_port (port). it's a whole little connection moment, obsessed 😭

⚠️ use this only if neither tty_port_register_device nor tty_port_install is used in the driver. like, for real for real. don't be out here doubling up 🙈

and if you do use it? it has to be called before tty_register_driver. not after, not during, before. that's the vibe check and you will not pass it otherwise 💀

🌈 SEE ALSO 🌈

kernel file ./drivers/tty/tty_port.c and honestly the whole tty_port friend group, no cap:

that's the whole page bestie, you ate that 🍓✨ and for the record this all lives under ./drivers/tty, dated October 2026 — mwah, go link some ports, ily 💖🧚‍♀️
