GPIB(4)

💅 GPIB(4) — the one where your kernel meets IEEE488 ✨

Okay bestie, so this is the GPIB page from the Kernel Interfaces Manual (that's section 4, the driver girlies 🎀), and it's short but it ate. Let's get into it.

🌸 NAME 🌸

cec — support for the IEEE488 GPIB. That's the whole name, no notes, she's a minimalist 👑

✨ SYNOPSIS ✨

gpib* at cec?

That's it. That's the config line. Put it in your kernel config and the gpib* device attaches at cec? — the ? is wildcard energy, iykyk 🦋

💖 DESCRIPTION 💖

The cec driver supports the IEEE488 general-purpose interface bus — aka GPIB — and honestly? It's giving "niche but iconic" 🔥 That's literally the whole description, no cap. The bus is general-purpose, the driver is cec, and they're in love your honor 💜

🎀 FILES 🎀

• /dev/gpib? — the GPIB device special file. That's where the magic (and the ?) lives 🍓

🌈 SEE ALSO 🌈

Go read these next, bestie, they're in the reading list fr fr:

• cs80bus(4)
• ct(4)
• mt(4)
• rd(4)

⭐ HISTORY ⭐

The cec driver appeared in NetBSD 2.0 — she's an elder icon, respect the roots 👑

💀 BUGS 💀

Okay so this is the part where we keep it real 🙈

The user-level interface to the gpib driver currently doesn't do anything useful. Like, at all. It's giving placeholder energy, not main character energy 😭

And that's not even the worst part — the GPIB subsystem places the unfortunate constraint that the local GPIB controller is always the controller in charge (CIC). No negotiation, no vibes check, she's CIC periodt. Unfortunate is the manpage's word, and honestly? Accurate.

So yeah — gpib has some unresolved childhood trauma. Manage your expectations accordingly 💅

🫶 And that's the page, bestie! This one's from the Debian edition, dated May 24, 2003 — vintage, retro, lowkey a time capsule 🕰️✨ Love that for us. Byeeee 💖
