lpfc_sli_resume_iocb(9)

🎀 lpfc_sli_resume_iocb(9) 🎀

okay so bestie, welcome to the kernel API manual — section 9, the big-kid kernel developer pages, no cap ✨ — and today's main character is a function called lpfc_sli_resume_iocb. she's a void, she takes two pointers, and she's here to push your pending work to the firmware. let's get into it 💅

---

💖 NAME 💖

lpfc_sli_resume_iocb — process iocbs in the txq 🌸

---

✨ SYNOPSIS ✨

void lpfc_sli_resume_iocb (struct lpfc_hba *phba , struct lpfc_sli_ring
*pring );

that's it. that's the whole signature. two pointers, zero return value, pure vibes 🫶

---

🦋 ARGUMENTS 🦋

• phba — pointer to the HBA context object. this is the whole adapter's little world, and she needs it 💜
• pring — pointer to the driver's SLI ring object. this is the specific ring she's working on, okay so know which one you're passing 🌈

---

🔥 DESCRIPTION 🔥

so here's the tea ☕ — this function gets called with hbalock held, and its whole job is to post the pending iocbs sitting in the txq over to the firmware. she's the little messenger that finally delivers the stack of stuff that was waiting 😭✨

and when does she get called? when the driver detects that there's space available in the ring. that's the moment. space appeared, so the queue gets to move again. she ate and left no crumbs, periodt 👑

lowkey important reminder bestie: hbalock is held when you call her. that's not optional, that's the whole contract 💀
