NVME_SET_FEATURES_IRQ_COALESCE(2)

💅 nvme_set_features_irq_coalesce(2) — bestie edition

okay so welcome to the libnvme API manual, and today's main character is nvme_set_features_irq_coalesce — she sets the IRQ coalesce feature and honestly? she ate. ✨

---

🌸 NAME 🌸

nvme_set_features_irq_coalesce — Set IRQ coalesce feature 🎀

---

🦋 SYNOPSIS 🦋

int nvme_set_features_irq_coalesce (int fd , __u8 thr , __u8 time , bool
save , __u32 *result );

like. that's the whole vibe. five little args and she's done. 💅

---

✨ ARGUMENTS ✨

• fd — the file descriptor of the nvme device. your ticket in, basically. 🎟️
• thr — the Aggregation Threshold. yes queen, set your threshold.
• time — the Aggregation Time. time is literally in the name bestie. ⏰
• save — save the value across power states. so she remembers you even after a nap. 😴💖
• result — the command completion result from CQE dword0. yeah, the receipts. 🧾

---

🔥 RETURN 🔥

She gives you the nvme command status if a response was received — go peek at enum nvme_status_field for the full lore — or -1 with errno set otherwise. so if it's -1, check errno, that's the tea. no cap. 💀

---

lowkey reminder: -1 means look at errno, enum nvme_status_field is where the status field names live. iykyk. 🫶

---

and that's the whole page, bestie — go forth and coalesce those interrupts. 🌈⭐

July 2026 energy, straight from the libnvme API manual — nvme_set_features_irq_coalesce(2) forever, mwah. 💖🧚👑
