jmicron_init_one(9)

💖 jmicron_init_one(9) 💖

okay so bestie, welcome to the Kernel API Manual entry for jmicron_init_one — yes that's a section 9 page, kernel-internals territory, and yes you're gonna slay it. sit down, grab a strawberry drink 🍓, and let's go.

---

✨ NAME ✨

jmicron_init_one — literally the function that registers a Jmicron ATA PCI device with kernel services. that's the whole vibe. no cap. 🎀

---

🌸 SYNOPSIS 🌸

int jmicron_init_one (struct pci_dev *pdev , const struct pci_device_id
*id );

like, that's the signature, exactly as written, don't come for me about the spacing, it's giving original-manpage energy 💅

---

🦋 ARGUMENTS 🦋

• pdev — the PCI device you're registering. the main character of this call, honestly 👑
• id — the PCI device ID. the supporting cast, still iconic 🫶

---

🌈 DESCRIPTION 🌈

so this one gets called from the kernel PCI layer. you're not the one summoning it, the layer is. it's giving "invited to the party, didn't plan the party." 🧚

LOCKING: the locking is inherited from the PCI layer, and heads up — it may sleep. so no, you cannot just call this from anywhere while holding a spinlock and expect the universe to be chill about it 😭

---

⭐ RETURN ⭐

• Zero on success 🎉 (the slay outcome)
• a -ERRNO value otherwise 💀 (the not-so-slay outcome)

---

🔥 SEE ALSO 🔥

• kernel file ./drivers/ata/pata_jmicron.c
• jmicron_pre_reset(9) — the other friend in this friend group, go say hi 👋

bestie reminder: every flag, argument, return value and caveat up there is exactly what the page says — I'm just making it cute, not making things up. iykyk 💜

and that's the page, mwah 💋 — brought to you by the source under ./drivers/ata, dated October 2026, and yes this whole thing lives in section 9 of the Kernel API Manual. periodt. 🌸💅✨
