mpi3mr_isr_poll(9)

💖 mpi3mr_isr_poll(9) 💖

okay bestie, welcome to the Kernel API Manual ✨ — this one's mpi3mr_isr_poll, and it's literally one little function from the mpi3mr driver fam. let's get into it 🎀

---

🌸 NAME 🌸

mpi3mr_isr_poll — the reply queue polling routine 💅

---

✨ SYNOPSIS ✨

irqreturn_t mpi3mr_isr_poll (int irq , void *privdata );

---

🦋 ARGUMENTS 🦋

• irq — the IRQ, bestie. that's it, that's the argument.
• privdata — the interrupt info 🫶

---

👑 DESCRIPTION 👑

so what does it do?? it polls for pending I/O completions in a loop 🔥 and it just keeps going — like, will not stop — until either pending I/Os are present, or the controller queue depth I/Os are processed. that's the whole vibe check: loop, loop, loop, until one of those two things hits 💀

---

⭐ RETURN ⭐

IRQ_NONE or IRQ_HANDLED 🫶 (that's the irqreturn_t energy, yk)
