💅 usb_gpib_interface_clear(9)

Okay bestie, welcome to the Kernel API Manual ✨ — this one's from the kernel side of things, and it's honestly so short you'll be done before your iced coffee melts. Let's get into it 🫶

🌸 NAME 🌸

usb_gpib_interface_clear — the function that asserts (or, like, claims to de-assert) IFC 💅

✨ SYNOPSIS ✨

void usb_gpib_interface_clear (struct gpib_board *board , int assert );

That's it. That's the whole vibe. No return value, no drama, no cap 🔥

🎀 ARGUMENTS 🎀

  • board — the gpib_board data area for this gpib interface. It's literally the home base for your interface, like the group chat where everything goes down 💖
  • assert — the vibe check switch, and it only has two settings:
    • 1 → assert IFC 👑
    • 0 → de-assert IFC 🙈

🦋 DESCRIPTION 🦋

So here's the tea, and ngl it's a little unhinged ☕

Right now, when you hit it with the assert request, we issue the lpvo IBZ command — and that command cycles IFC low for 100 usec ⏱️ iconic, precise, love that for us.

Then? We straight up ignore the de-assert request 💀 Like, not me ignoring it completely. That's the current behaviour, that's what's happening, and the manpage is just being honest about it fr fr.

bestie please note: the de-assert request is ignored. This isn't a bug report, it's just the documented behaviour — so don't come for the docs when 0 does nothing 🙈

The kernel file lives at ./drivers/gpib/lpvo_usb_gpib/lpvo_usb_gpib.c — go read it if you want the full lore 📖 And say hi to the whole squad:

And that's the whole page, queen 👑 This little gem ships out of ./drivers/gpib/lpvo_usb_gpib, dated October 2026 — go forth and assert your IFC 💅✨
