dpni_get_queue(9)

💖 dpni_get_queue(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this is the page for dpni_get_queue, and yes it's exactly what it sounds like: you're getting your queue parameters back out of the DPAA2 life. no cap, it's a little function with a lot of friends (see the SEE ALSO at the bottom, it's giving squad goals 🫶).

---

✨ SYNOPSIS ✨

int dpni_get_queue (struct fsl_mc_io *mc_io , u32 cmd_flags , u16 token
, enum dpni_queue_type qtype , u8 tc , u8 index , struct dpni_queue
*queue , struct dpni_queue_id *qid );

she's long, she's lowercase-ish, she returns an int — iconic behavior honestly 💅

---

🌸 ARGUMENTS 🌸

• mc_io — Pointer to MC portal's I/O object. like, your little handle to the management complex portal, that's the vibe 🦋
• cmd_flags — Command flags; one or more of MC_CMD_FLAG_. pick your flags, be free ✨
• token — Token of DPNI object. it's a u16, it identifies your DPNI, pls don't lose it 🙈
• qtype — Type of queue — all queue types are supported, and we love an inclusive queen 👑
• tc — Traffic class, in range 0 to NUM_TCS - 1. respect the range, she's strict 💀
• index — Selects the specific queue out of the set allocated for the same TC. Value must be in range 0 to NUM_QUEUES - 1. again: range check is real, do not test her 🎀
• queue — Queue configuration structure. this is where the tea gets poured 🍓
• qid — Queue identification. your queue's little ID card, very main character 📇

💀 RETURN 💀

bestie… the RETURN section is literally empty in this manpage. not me noticing that 😭 the return type is int in the synopsis up there, but the original page documents nothing under RETURN, so i'm not gonna make something up. periodt. ✋

ngl that's a whole vibe check fail from whoever wrote the original, but we respect the source material around here 🫶
