pdc2027x_set_piomode(9)

💅 pdc2027x_set_piomode 💅

okay so bestie, this is a page from the Kernel API Manual — yes, the kernel has its own manual, we love a documented icon — and it's all about pdc2027x_set_piomode. no cap, it's a tiny one, but we're gonna treat it with the respect it deserves. 🎀

---

✨ NAME ✨

pdc2027x_set_piomode — like, initialize the host controller's PATA PIO timings. that's the whole vibe. 🦋

---

✨ SYNOPSIS ✨

void pdc2027x_set_piomode (struct ata_port *ap , struct ata_device *adev
);

literally that's it. one function, two args, void return, she's lowkey minimal. 💅

---

✨ ARGUMENTS ✨

• ap — the port to configure. like, which port are we doing a glow-up on. 🌸
• adev — um. yeah. that's what it says. that's the whole description. i'm not gonna lie to you bestie, the docs said "um" and i respect the honesty 😭🙈 — it's a struct ata_device *, if that helps, which iykyk.

---

✨ DESCRIPTION ✨

set PIO mode for the device. short, sweet, main character energy — she does exactly one thing and she does it. ✨

LOCKING: None (inherited from caller). so no locks in here, she's borrowing her friend's — don't come for her about it, it's inherited, periodt. 🔥

real talk: because the locking is inherited, whoever calls this is the one holding the lock. not her problem. 💀
