💅 qbman_swp_en..._desc_direct(9) 💅

okay so bestie, this is a page straight out of the Kernel API Manual, and it's giving "niche driver lore that only three people on earth understand" 💀 but don't worry, we're gonna get you through it. Stay with me 🫶

✨ NAME ✨

qbman_swp_enqueue_multiple_desc_direct — Issue a multi enqueue command using multiple enqueue descriptor. yeah. it's a mouthful. it's iconic like that 💅

🌸 SYNOPSIS 🌸

int qbman_swp_enqueue_multiple_desc_direct (struct qbman_swp *s , const
struct qbman_eq_desc *d , const struct dpaa2_fd *fd , int num_frames );

like, that's the whole vibe right there ✨ four params, one int coming back at you.

🎀 ARGUMENTS 🎀

  • s — the software portal used for enqueue. this is your main character 🫶 the portal you're doing the enqueueing through.
  • d — table of minimal enqueue descriptor. yes, a table of them, plural energy 💅
  • fd — table pointer of frame descriptor table to be enqueued. it's a pointer, to a table, of frame descriptors. nested like my emotions 😭
  • num_frames — number of fd to be enqueued. literally the count. how many are we sending. that's it 🍓

🦋 DESCRIPTION 🦋

Return the number of fd enqueued, or a negative error number. short and sweet, no cap. so you either get a happy little count back, or a negative number, which is the code's way of saying "bestie… no 🙈" — that's your error signal 🔥

ngl if you're new here, the *_direct ones and the *_mem_back ones are cousins — you'll clock the pattern fast, iykyk 💜

and that's the page, bestie 💖 this little gem lives under ./drivers/soc/fsl/dpio, dated October 2026, and it's part of the Kernel API Manual — go forth and enqueue, you absolute legend 👑✨
