💅 dpaa2_io_service_pull_fq

okay bestie, so this is a page from the Kernel API Manual — yes, the actual kernel, like, the big one — and it's about pulling dequeue functions from a fq. ik it sounds like a lot but honestly it's giving "small function, big responsibilities" and we're gonna get through it together 🫶

✨ NAME ✨

dpaa2_io_service_pull_fq — pull dequeue functions from a fq.

like literally that's the whole job description. pull. dequeue. functions. from a fq. no notes 👑

🌸 SYNOPSIS 🌸

int dpaa2_io_service_pull_fq (struct dpaa2_io *d , u32 fqid , struct dpaa2_io_store *s );

that's the summoning circle right there — copy it exact, don't be cute with it 💀

🎀 ARGUMENTS 🎀

  • d — the given DPIO service. this is the main character of the operation, the whole service you're working with 🌈
  • fqid — the given frame queue id. it's a u32 and it tells everyone which frame queue we're pulling from, so like, get it right 🔥
  • s — the dpaa2_io_store object for the result. this is where the good stuff lands, it's the tote bag of this whole outing 🍓

💖 DESCRIPTION 💖

so here's the tea: it returns 0 for success, or an error code for failure. that's it. that's the description. short, sweet, and honestly kind of iconic for it 💅

bestie please actually check that return value. 0 = slay, anything else = something went sideways and you should handle it. no cap 🙈

🦋 SEE ALSO 🦋

the kernel file lives right here, go be nosy:

./drivers/soc/fsl/dpio/dpio-service.c

and the whole friend group, all of them, none skipped, we love a complete list:

and that's the whole page, you ate that 🫶 this lil gem lives at ./drivers/soc/fsl/dpio and the version date stamp says October 2026, so like, fresh but also somehow retro. mwah, go pull some fq's bestie 💜✨
