megaraid_ack_sequence(9)

💅 megaraid_ack_sequence — like, the interrupt ack sequence for memory mapped HBAs (it's a man 9 kernel API page, iykyk)

okay so bestie, welcome to the kernel API manual, we're in the 9 section today and this page is called megaraid_ack_sequence. yes it's a whole mouthful, no I will not be shortening it, it's iconic and it deserves its full name 💖

---

✨ NAME ✨

megaraid_ack_sequence — the interrupt ack sequence for memory mapped HBAs. that's it, that's the whole vibe 🎀

---

🌸 SYNOPSIS 🌸

int megaraid_ack_sequence (adapter_t *adapter );

---

🦋 ARGUMENTS 🦋

• adapter — the controller's soft state. that's the thing you're passing in, she's carrying all the state, treat her right 🫶

---

💫 DESCRIPTION 💫

so this is the interrupt acknowledgement sequence for memory mapped HBAs. what it does is: find out which command actually finished, then put those completed commands onto the completed list so they can be processed later. very "sort the mail now, deal with it later" of her honestly 💅

---

⭐ RETURN ⭐

returns 1 if the interrupt is valid, 0 otherwise. simple as that, no cap 🔥

and that's the page!! before you go — this lil beauty comes from ./drivers/scsi/megaraid, dated October 2026, and she's filed under megaraid_ack_sequence(9) in the Kernel API Manual. slay, go ack those interrupts responsibly 🧚✨
