ionic_queue_init(9)

📦 version 7.3.1, in nixpkgs unstable

✨ ionic_queue_init — bestie, let's set up a queue 💅

okay so real talk, this is ionic_queue_init(9) from the Kernel API Manual, and honestly? it's giving "small function, big responsibility" energy. it's the one that takes your sad little uninitialized queue struct and makes it a real queue. slay. 🎀

🌸 SYNOPSIS 🌸

int ionic_queue_init (struct ionic_queue *q , struct device *dma_dev ,
   int depth , size_t stride );

int, four args, no drama. periodt. ✨

🦋 ARGUMENTS 🦋

  • q — the uninitialized queue structure, aka the blank canvas, the main character before their glow-up. she is not ready yet. you're about to fix that. 💖
  • dma_dev — the DMA device for mapping. this is the device that does the actual memory-mapping work, so yeah, she matters. 🔥
  • depth — depth of the queue. how many elements deep we're going. 🌈
  • stride — size of each element of the queue, size_t flavored. every element gets this much room. no cap. 💅

👑 RETURN 👑

returns a status code. that's it, that's the whole vibe check — check it, bestie. 🙈

🧚 SEE ALSO 🧚

the kernel file lives at ./drivers/infiniband/hw/ionic/ionic_queue.h, and the struct in question is struct ionic_queue(9). and omg the friend group is huge, look at all these icons:

literally the whole squad 🫶⭐

ngl, q has to be uninitialized going in — that's the whole point, that's her before the makeover. don't come in here with a queue you already messed with and expect this to be the glow-up. 😭

k bye bestie, go init that queue 💜 — this page came from ./drivers/infiniband/hw/ionic, dated October 2026, and it's ionic_queue_init(9) all day every day. 🍓🌸
