NVME_SET_FEATURES_IRQ_CONFIG(2)

✨ nvme_set_features_irq_config ✨

okay bestie, welcome to the libnvme API manual</> — this one's about nvme_set_features_irq_config, aka the glow-up your interrupt setup deserves 💅

---

🌸 NAME 🌸

nvme_set_features_irq_config — Set IRQ config feature

like. it sets the IRQ config feature. that's the whole job. she's an icon, she's a legend, and she is THE moment 🎀

---

🦋 SYNOPSIS 🦋

int nvme_set_features_irq_config (int fd , __u16 iv , bool cd , bool
save , __u32 *result );

no cap, that's the whole signature. five args, one int coming back at ya ✨

---

💖 ARGUMENTS 💖

• fd — File descriptor of nvme device. this is your ✨portal✨ to the drive, bestie. no fd, no vibes.
• iv — Interrupt Vector. which vector are we talking to? this one. type is __u16, so keep it in range, periodt.
• cd — Coalescing Disable. a bool — so it's giving true/false energy. disable the coalescing or don't, your call 🫶
• save — Save value across power states. bool again. do you want this to survive a power state change? then say yes, queen.
• result — The command completion result from CQE dword0. it's a __u32 *, so it's a pointer — she writes back into your little variable and tells you what the CQE dword0 said 📬

---

🌈 RETURN 🌈

The nvme command status if a response was received (see enum nvme_status_field) or -1 with errno set otherwise.

so: got a response → you get the nvme command status, and you go look it up in enum nvme_status_field. no response / it went sideways → -1 and errno is set. check your errno, bestie, she's always trying to tell you something 😭

fr fr, if you see that -1, don't just vibe past it. something is UP.
