qbman_swp_pull_direct(9)

💅 qbman_swp_pull_direct(9) — the Kernel API Manual page, bestie edition 🎀

okay so this is qbman_swp_pull_direct(9) from the Kernel API Manual, and honestly? it's a tiny little function with main character energy. it does exactly one thing and does it cute. let's get into it ✨

---

🌸 NAME 🌸

qbman_swp_pull_direct — literally just issues the pull dequeue command. that's it. that's the whole vibe. 💅

---

🦋 SYNOPSIS 🦋

int qbman_swp_pull_direct (struct qbman_swp *s , struct qbman_pull_desc
*d );

no cap, that's the whole signature. copy it exactly, don't get creative with it 🙈

---

💖 ARGUMENTS 💖

• s — bestie, this is the software portal object. the portal. the moment. 🫶
• d — the software portal descriptor, and important detail: it has to have already been configured with the whole set of qbman_pull_desc_set_*() calls. like, you gotta do your homework first, it's not gonna do it for you ✨

---

🔥 DESCRIPTION 🔥

so here's the tea 🍓: it returns 0 for success, and -EBUSY if the software portal is not ready to do pull dequeue. that's it. that's the whole description. short and iconic, we love a low-effort legend 👑

ngl the -EBUSY thing is not a vibe — your portal literally said "not right now" 😭 handle it, don't ignore it.
