liquidio_setup_io_queues(9)

📦 version 7.3.1, in nixpkgs unstable

💖 liquidio_setup_io_queues — like, the whole queue glow-up 💖

okay bestie, welcome to the Kernel API Manual page for liquidio_setup_io_queues(9) — yes that's the whole function name, no we're not abbreviating it, it's iconic and it knows it 💅

✨ NAME ✨

liquidio_setup_io_queues — sets up the input and output queues. that's it, that's the vibe. in and out, both handled, main character energy fr 🎀

🦋 SYNOPSIS 🦋

int liquidio_setup_io_queues (struct octeon_device *octeon_dev , int
ifidx , u32 num_iqs , u32 num_oqs );

it returns an int, it takes four things, and honestly? she's neat about it 🌸

🎀 ARGUMENTS 🎀

  • octeon_dev — the octeon device. like, the device. the one we're doing all this for 🫶
  • ifidx — the interface index. which interface we're talking about, bestie, keep up 💜
  • num_iqs — input io queue count. how many input queues we stan.
  • num_oqs — output io queue count. same energy, but for output 🦋

💀 NOTE 💀

okay this is the part where you have to actually pay attention, because it is so easy to get twisted 😭

the queues are with respect to the octeon device. so:

  • an input queue is for egress packets
  • an output queue is for ingress packets

like... yes. i know. input = out, output = in. that's just how the octeon device rolls, ngl it's giving chaos but it's their chaos and we respect it 🌈

do not come for me about this, i did not name them, i am simply the messenger 💅
