dpdmai_set_rx_queue(9)

📦 version 7.3.1, in nixpkgs unstable

💅 dpdmai_set_rx_queue(9) — like, the Kernel API Manual page you didn't know you needed 🎀

okay so bestie, welcome to the Kernel API Manual ✨ — yes that's the manual name, and yes we're getting into it. This one's about dpdmai_set_rx_queue, which (spoiler) sets the Rx queue configuration. Short king of a function, but we're gonna treat it right 🫶

🌸 NAME 🌸

dpdmai_set_rx_queue — Set Rx queue configuration 💖 that's it, that's the whole job, and honestly? iconic.

✨ SYNOPSIS ✨

int dpdmai_set_rx_queue (struct fsl_mc_io *mc_io , u32 cmd_flags , u16
token , u8 queue_idx , u8 priority , const struct dpdmai_rx_queue_cfg
*cfg );

she returns an int, she takes six whole arguments, and she is not sorry about it 💅

🦋 ARGUMENTS 🦋

  • mc_io — Pointer to MC portal's I/O object. like, your lil handle to the portal, that's the vibe 🔌
  • cmd_flags — Command flags; one or more of 'MC_CMD_FLAG_'. pick your flags, bestie, it's a whole set 🚩
  • token — Token of DPDMAI object. this is your object's lil name tag 🏷️
  • queue_idx — DMA queue index. which queue we talking about?? this is how you say it 📇
  • priority — Select the queue relative to number of priorities configured at DPDMAI creation. so the number of priorities was already locked in when the DPDMAI got created — you're just choosing a queue relative to that ⚖️
  • cfg — Rx queue configuration. the actual config, the main character of the whole call 👑

💀 RETURN 💀

so... the original literally just has the heading with nothing under it 😭 not a single value, not a single word. i'm not gonna make stuff up, so: no return description is given. bestie the manpage left it on read 🙈

pssst — and yes, it does declare int in the synopsis, so like, the type is right there, that's all we're saying, i'm not out here inventing exit statuses for you 💀

🌈 SEE ALSO 🌈

bestie it's a whole squad, a friend group, a roster 👑 — all in the Kernel file ./drivers/dma/fsl-dpaa2-qdma/dpdmai.c:

and also just ./drivers/dma/fsl-dpaa2-qdma itself, like the whole folder is the moment 🦋

⭐ reminder bestie: every single flag, every single number and every single name up there is verbatim, so you can copy-paste straight into your code and not get clowned on. no cap 💖

and that's the page!! 🎀 mwah 🫶

okay final sign-off, because we do cite our sources in this house: this one comes from ./drivers/dma/fsl-dpaa2-qdma, dated October 2026 — and it's the dpdmai_set_rx_queue(9) page, slay, periodt ✨💅
