✨ legacy_probe_add(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for legacy_probe_add — yes, she's giving vintage. get comfy 💅

---

🎀 NAME 🎀

legacy_probe_add — adds an interface to the probe list 🫶

---

🌸 SYNOPSIS 🌸

int legacy_probe_add (unsigned long port , unsigned int irq , enum
       controller type , unsigned long private );

---

🦋 ARGUMENTS 🦋

• port — the controller port. like, the actual I/O port, bestie 💖
• irq — the IRQ number. yes, the interrupt one ✨
• type — the controller type 🎀
• private — controller-specific info. it's giving "you had to be there" 🙈

---

💜 DESCRIPTION 💜

so legacy_probe_add adds an entry into the probe list for ATA controllers. iconic behavior, honestly. 🔥

the way this works: it's used to add the default ISA slots first, and then to build up the table further according to other ISA / Weird device scans. yes, "Weird" with a capital W — that's what the page says, no cap 👑

ngl, an I/O port list is used here to keep the ordering stable and sane, literally because we don't have any good way to talk about ordering otherwise. so the list is the whole personality. periodt 💀
