ixgbevf_set_ivar(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ixgbevf_set_ivar(9) — like, the Kernel API Manual page, bestie ✨

okay so picture this: it's a Kernel API Manual page, the star of the show is ixgbevf_set_ivar, and she's here to serve 💅

✨ NAME ✨

ixgbevf_set_ivar — sets the IVAR registers, which is literally the whole "map interrupt causes to vectors" situation 🎀 no cap, that's her job.

🌸 SYNOPSIS 🌸

void ixgbevf_set_ivar (struct ixgbevf_adapter *adapter , s8 direction ,
u8 queue , u8 msix_vector );

she takes four things and returns void — a true queen who gives nothing back except vibes and correctly-routed interrupts 🫶

🦋 ARGUMENTS 🦋

  • adapter — pointer to adapter struct, the main character of this whole operation 👑
  • direction — 0 for Rx, 1 for Tx, -1 for other causes. that's it, that's the encoding, iykyk 🧚
  • queue — the queue you're mapping the corresponding interrupt to 🍓
  • msix_vector — the vector you're mapping to the corresponding queue. yes bestie, queue ➡️ vector, that's the pairing 💖

💜 SEE ALSO 💜

okay this is the part where she tags literally everyone in the group chat, and ngl the list is long, but we do not skip a single one, periodt 🔥

the kernel file first, obviously: Kernel file ./drivers/net/ethernet/intel/ixgbevf/ixgbevf_main.c

and then the whole squad, in order, exactly as written:

like i said. everyone. and i mean everyone 💀 but honestly? iconic behavior, reading the whole list is self-care 🌈

lowkey reminder bestie: that -1 for direction is not a typo and not a vibe, it's literally "other causes" — do not come for her 💅

and that's the page! 🎀 source/version situation is ./drivers/net/ethernet/intel/i... and she's dated October 2026, footer still reads ixgbevf_set_ivar(9) because she never misses her cue ✨ slay, stay hydrated, go map those vectors 💖🦋
