💅 qbman_swp_init(9) — a little Kernel API Manual moment ✨

okay bestie, welcome to the glow-up of qbman_swp_init, straight out of the Kernel API Manual. it's short, it's sweet, it's giving "small function, big responsibility" energy, and we're gonna read it together 🫶

🌸 NAME 🌸

qbman_swp_init — creates a functional object that represents the given QBMan portal descriptor. that's it, that's the whole job, and honestly? iconic.

✨ SYNOPSIS ✨

struct qbman_swp * qbman_swp_init (const struct qbman_swp_desc *d );

like, look at that signature. the way it takes a const struct qbman_swp_desc * and hands you back a struct qbman_swp *... no cap, it ate 💅

🎀 ARGUMENTS 🎀

  • d — the given qbman swp descriptor. yeah it's just the descriptor you're handing in, bestie. that's the whole input 🦋

💖 DESCRIPTION 💖

so what happens? it returns the qbman_swp portal when things go right. and if the object can't be created? you get NULL. the end. no dramatic monologue, no extra steps, just success portal or NULL 😭

lowkey a mood: NULL is the "not me, not today" of return values 💀

that's 38 cross-references, and yes i counted, because that's the kind of main character energy this page deserves 👑

and that's the whole thing, bestie 🧚 this cutie pie of a page ships from ./drivers/soc/fsl/dpio, dated October 2026 — so go forth, init your portals, and remember: when in doubt, check the return value 🍓💜
