locomo_probe(9)

💖 locomo_probe(9) — the Kernel API Manual, bestie edition ✨

okay so this is locomo_probe(9), straight out of the Kernel API Manual, and honestly? she's a little icon. let's get into it 🎀

---

🌸 NAME 🌸

locomo_probe — probe for a single LoCoMo chip 💅

like, one chip. a single one. not a crowd. that's her whole thing ✨

---

🦋 SYNOPSIS 🦋

int locomo_probe (struct platform_device *dev );

yep, that's the whole signature. int in the front, platform device in the middle, and that trailing space before the closing paren is part of the vibe, we don't touch it 🫶

---

💜 ARGUMENTS 💜

• dev — platform device 🧚

that's it. that's the argument. she takes one platform device and she takes it seriously 💖

---

🌈 DESCRIPTION 🌈

okay so bestie, listen up: locomo_probe probes for a LoCoMo chip 🔥

and the important bit — the no cap bit — is that this must be called before any other locomo-specific code. like, before. not after, not "ehh somewhere in the vicinity", not "I'll get to it". before. she's the main character and everyone else waits their turn 👑

---

⭐ RETURN ⭐

this is the part where she tells you how it went, and ngl she's got range 😭

• -EINVAL — the device's IORESOURCE_MEM was not found 💀
• -ENXIO — could not allocate an IRQ for the device 🙈
• -ENODEV — device not found.
• -EBUSY — the physical address is already marked in-use. she's taken, sorry 🚫
• -ENOMEM — could not allocate or iomap memory 🌸
• 0 — successful. slay. ate. periodt ✨🎉

---

💡 tiny note bestie: 0 is the good one. if you see a negative number, that's the kernel going "hm" and you should probably read the list again 💅
