mei_cl_irq_dma_map(9)

💅 NAME 💅

mei_cl_irq_dma_map — bestie, this one sends a client dma map request, and it does it in irq_thread context ✨ (yes, interrupt-thread land, we're fancy like that)

---

✨ SYNOPSIS ✨

int mei_cl_irq_dma_map (struct mei_cl *cl , struct mei_cl_cb *cb ,
       struct list_head *cmpl_list );

That's the whole vibe check right there — returns an int, takes three things, done 🫶

---

🫶 ARGUMENTS 🫶

• cl — the client 💖 that's it, that's the argument
• cb — the callback block, lowkey where all the action lives
• cmpl_list — the complete list, the "who's done" list, iconic behavior honestly

---

🎀 RETURN 🎀

Returns 0 on success and an error otherwise — no cap, that's the whole deal 😭 so always check your return value, bestie, fr fr

ngl a nonzero return here means something went sideways, and the manpage does not elaborate, so don't go inventing meanings 💀 just know: 0 = slay, anything else = not slay.
