qbman_swp_e...ple_mem_back(9)

🎀 NAME 🎀

okay so bestie, you’re in the Kernel API Manual and this page is qbman_swp_enqueue_multiple_mem_back(9) — the header gives it the little nickname qbman_swp_e...ple_mem_back(9), which is lowkey iconic. The actual name is qbman_swp_enqueue_multiple_mem_back and it does one thing: Issue a multi enqueue command using one enqueue descriptor. slay.

✨ SYNOPSIS ✨

here’s the signature, bestie — copy it exactly, no autocorrect:

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

💖 ARGUMENTS 💖

• s — the software portal used for enqueue. Your portal, your power 💅
• d — the enqueue descriptor. The descriptor in question, periodt.
• fd — table pointer of frame descriptor table to be enqueued.
• flags — table pointer of QBMAN_ENQUEUE_FLAG_DCA flags, not used if NULL.
• num_frames — number of fd to be enqueued.

🦋 DESCRIPTION 🦋

short and sweet: it returns the number of fd enqueued, or a negative error number. That’s the whole tea ☕ no extra lore, no cap.
