📦 version 7.3.1, in nixpkgs unstable

✨ tty_port_register_device_attr(9) ✨

okay bestie, buckle up 💖 this one's from the Kernel API Manual, and it's genuinely so useful once it clicks, i promise.

🌸 NAME 🌸

tty_port_register_device_attr — register tty device 🎀

🦋 SYNOPSIS 🦋

struct device * tty_port_register_device_attr (struct tty_port *port ,
struct tty_driver *driver , unsigned index , struct device *device ,
void *drvdata , const struct attribute_group **attr_grp );

like, six whole arguments, she's a lot but she's worth it 💅

👑 ARGUMENTS 👑

  • port — the tty_port of the device 🫶
  • driver — the tty_driver for this device
  • index — the index of the tty, aka which one she is
  • device — the parent, if there is one; otherwise NULL 😌
  • drvdata — the driver data that gets set to the device
  • attr_grp — the attribute group to be set on the device ✨

💜 DESCRIPTION 💜

okay so, literally, it's the same as tty_register_device_attr — except the provided port is linked to a concrete tty specified by index. that's the whole vibe check 🦋

use this one, or tty_port_install (or both, honestly, go off 👑). and call tty_port_link_device as a last resort, like only if nothing else works, no cap 💀

🌈 SEE ALSO 🌈

kernel file ./drivers/tty/tty_port.c — and here's the whole squad, they all ate fr fr:

ngl bestie, that's the whole page 💀 go forth and register those ttys 🌸

and that's a wrap, mwah 💋 — this little gem lives in ./drivers/tty, dated October 2026, and it's page tty_port_re..._device_attr(9) of the Kernel API Manual. slay 🎀✨
