mpi3mr_send_event_ack(9)

mpi3mr_send_event_ack(9) 💅✨

okay bestie, welcome to the Kernel API Manual page for mpi3mr_send_event_ack(9) — yes, that exact function, and we’re gonna make it make sense 🫶

---

🌸 NAME 🌸

mpi3mr_send_event_ack — issue event acknwoledgment request (typo and all, bestie 😭💖)

---

✨ SYNOPSIS ✨

the whole signature is giving:

void mpi3mr_send_event_ack (struct mpi3mr_ioc *mrioc , u8 event , struct
mpi3mr_drv_cmd *cmdparam , u32 event_ctx );

---

🎀 ARGUMENTS 🎀

• mrioc — adapter instance reference. it’s the adapter’s main character ID 💅
• event — MPI3 event id 👑
• cmdparam — internal command tracker 🎯
• event_ctx — event context 🧚

---

💖 DESCRIPTION 💖

okay so what it actually does: it issues the event acknowledgment request to the firmware if there is a free command to send the event ack. if there isn’t a free command, it puts it on a pend list so it will be processed on a completion of a prior event acknowledgment. that’s the whole flow, no cap ✨

---

⭐ RETURN ⭐

Nothing — literally nothing, bestie 😌 not a value, not a struct, just Nothing.
