lpfc_debug_dump_cq(9)

📦 version 7.3.1, in nixpkgs unstable

💖 lpfc_debug_dump_cq — the kernel API manual, bestie edition 💖

okay so this is lpfc_debug_dump_cq(9), straight out of the Linux kernel API manual, and it's lowkey a tiny little function with one very specific job. let me tell you everything about it, no cap. 🦋

✨ NAME ✨

lpfc_debug_dump_cq — dumps all entries from a FCP or NVMe work queue's cmpl queue. that's it, that's the whole vibe. 💅

🌸 SYNOPSIS 🌸

void lpfc_debug_dump_cq (struct lpfc_hba *phba , int qtype , int wqidx );

it's a void function, so it doesn't return anything back to you — it just does the thing and dips. iconic behaviour tbh. ✨

🎀 ARGUMENTS 🎀

  • phba — pointer to the HBA context object. like, the main character struct, fr fr. 👑
  • qtype — okay bestie, the manual literally just says -- undescribed -- here 😭 i am NOT making up a description for it, that's not the move. the original page doesn't describe it and neither will i. respect the mystery. 🙈
  • wqidx — index to a FCP work queue. it's the number that points at which FCP work queue we're talking about. 🎯

🔥 DESCRIPTION 🔥

so here's the tea: this function dumps all entries from a FCP or NVME completion queue. and which completion queue does it dump from? the one associated to the work queue specified by the wqidx. so like, you hand it a wqidx, it finds the matching cmpl queue, and it dumps every entry in there. no skipping, no filtering, all of them. the way that it just empties the whole thing out — obsessed. 💖

ngl, the linked man pages are the place to go if you want the actual details on the other dump functions — this page only covers lpfc_debug_dump_cq itself. 💜

okay that's the whole page, bestie, you ate that reading comprehension moment 🌈 and for the cute little sign-off: this one lives in ./drivers/scsi/lpfc, the source/version footer says October 2026, and the page is lpfc_debug_dump_cq(9) — periodt. 💅🎀⭐
