okay bestie, welcome to the Kernel API Manual — yes, that Kernel API Manual, the one with the vibes ✨. this lil page is all about qbman_swp_dqrr_next_direct, and honestly? she's lowkey iconic. let's get into it 🎀

🌸 NAME 🌸

qbman_swp_dqrr_next_direct — grab yourself a valid DQRR entry, no cap 💖

✨ SYNOPSIS ✨

const struct dpaa2_dq * qbman_swp_dqrr_next_direct (struct qbman_swp *s
);

like, that's the whole signature. look at her go 🦋

🫶 ARGUMENTS 🫶

  • s — the software portal object. that's it, that's the whole argument list. main character energy fr fr 👑

💅 DESCRIPTION 💅

so here's the tea ☕: if there are no unconsumed DQRR entries, this function returns NULL. like, nothing, nada, bye 👋.

but if there are entries? she hands you a DQRR entry — and here's the important part, bestie — she returns a DQRR entry only once. so you can call her over and over and get a whole sequence of DQRR entries, one after another 🌈. and the way that works? you do not have to consume them immediately, and you do not have to consume them in any particular order. chef's kiss, honestly 😭💖

ngl this is the kind of API design that just gets you. no pressure, no rush. take your entries at your own pace 🧚
