qbman_swp_e...tiple_direct(9)

💅 qbman_swp_enqueue_multiple_direct ✨

okay bestie, so this is a page straight out of the Kernel API Manual, and honestly? It's giving "one descriptor, many frames, zero chill." Let's get into it 🫶

---

🌸 NAME 🌸

qbman_swp_enqueue_multiple_direct — issue a multi enqueue command using one enqueue descriptor

like, ONE descriptor. MULTIPLE frames. it's efficient, it's iconic, it's doing the most with the least 💅

---

✨ SYNOPSIS ✨

int qbman_swp_enqueue_multiple_direct (struct qbman_swp *s , const
struct qbman_eq_desc *d , const struct dpaa2_fd *fd , uint32_t *flags ,
int num_frames );

that's the whole vibe right there. int going in, int coming out, lots of pointers in between 🎀

---

🦋 ARGUMENTS 🦋

• s — the software portal used for enqueue. this is the main character, the portal doing all the work 💖
• d — the enqueue descriptor. singular. one. and it's carrying the whole multi-frame moment, no cap ✨
• fd — table pointer of frame descriptor table to be enqueued. it's a table, bestie, not just one fd — read the room 📋
• flags — table pointer of QBMAN_ENQUEUE_FLAG_DCA flags, not used if NULL. so like, pass NULL and it literally does not care, lowkey iconic 🙈
• num_frames — number of fd to be enqueued. how many. count them. that's the assignment 🔢

---

🔥 DESCRIPTION 🔥

return the number of fd enqueued, or a negative error number.

that's it. that's the whole description. short, sweet, and honestly kind of slaying 💀

so if the return value is negative, that's your villain arc — it's an error number, not a count. read it carefully, bestie 😭
