dpaa2_io_service_release(9)

📦 version 7.3.1, in nixpkgs unstable

💅 dpaa2_io_service_release(9) — like, the Kernel API Manual page, bestie 🎀

okay so picture this: it's a Kernel API Manual page, the function is dpaa2_io_service_release, and it's lowkey the "give the buffers back" girlie of the DPIO world. she's not flashy, she's not doing the most — she just returns your buffers to a buffer pool and dips. and honestly? iconic. ✨

🦋 NAME 🦋

dpaa2_io_service_release — release buffers to a buffer pool. that's it, that's the whole job description. no cap. 🫶

🌸 SYNOPSIS 🌸

int dpaa2_io_service_release (struct dpaa2_io *d , u16 bpid , const u64
*buffers , unsigned int num_buffers );

like literally that's the whole signature, take it in. 📜

✨ ARGUMENTS ✨

here's the cast of characters, and yes every single one of them matters 💖

  • d — the given DPIO object. she's the main character here, everything runs through her 👑
  • bpid — the buffer pool id. this is which pool we're talking about, don't mix 'em up 🙈
  • buffers — the buffers to be released. hand 'em over, bestie 🎁
  • num_buffers — the number of the buffers to be released. gotta know how many you're giving back, fr fr 🔢

🌈 DESCRIPTION 🌈

so the vibe check on the return value is basically this: return 0 for success, and a negative error code for failure. that's the entire description. short and slay. if you get a 0 you ate, and if it's negative… well, not me getting an error code 😭💀

lowkey important: the negative return means something went wrong — don't just ignore it and pretend everything's fine, bestie. that's not the energy. 🚩

and that's a wrap, bestie 🎀✨ this little page lives at ./drivers/soc/fsl/dpio and it's stamped October 2026 — so go forth, release those buffers, and slay 💅🔥
