lpfc_sli4_calc_ring(9)

📦 version 7.3.1, in nixpkgs unstable

💅 lpfc_sli4_calc_ring — a Kernel API Manual moment ✨

okay so picture this: it's a Kernel API Manual page, the title up top is literally lpfc_sli4_calc_ring(9), and it's about to tell you which ring to use. riveting, i know, but stay with me bestie 🫶

🌸 NAME 🌸

lpfc_sli4_calc_ring — calculates which ring to use 🎀

✨ SYNOPSIS ✨

struct lpfc_sli_ring * lpfc_sli4_calc_ring (struct lpfc_hba *phba ,
struct lpfc_iocbq *piocb );

literally the whole signature, copied exactly, no cap 💅

🎀 ARGUMENTS 🎀

  • phba — a pointer to the HBA context object. the main character of the context world 👑
  • piocb — a pointer to the command iocb. the little command guy whose fate we're about to decide 🦋

🦋 DESCRIPTION 🦋

so here's the vibe check: this is for SLI4 only, bestie. For SLI4 only, FCP IO can deferred to one fo many WQs (yes the original says one fo many 😭 typo and all, we're keeping her, she's iconic), based on hba_wqidx. because of that, we need to calculate the corresponding ring 🔥

and here's the important part: since ABORTS must go on the same WQ of the command they are aborting, we use the command's hba_wqidx. like, aborts do NOT get to go wandering off to a different WQ, they follow their command, periodt 💀

💖 SEE ALSO 💖

okay so this part is a lot, but i promised to keep every single one, so buckle up bestie, we're going on a journey. Kernel file ./drivers/scsi/lpfc/lpfc_sli.c and also:

that's all of them, every last one, you're welcome bestie 😭💖

ngl, no errors, exit statuses, or warnings on this page — what you see is what you get, and what you get is a ring calculator 💀

okay and finally, the little footer moment: this whole thing lives at ./drivers/scsi/lpfc and it's dated October 2026 — so yeah, future-dated kernel lore, iykyk ✨👑 thanks for coming to my ted talk, slay, periodt 💅🎀🌈
