nvme_set_features_nopsc(2)

✨ nvme_set_features_nopsc ✨

okay bestie, so this is a libnvme API manual page for the function nvme_set_features_nopsc 💖 and it's literally here to set the non-operational power state feature. That's it. That's the whole vibe. She's a setter, she's iconic, she shows up, she does the thing, she leaves. 🎀

🌸 SYNOPSIS 🌸

int nvme_set_features_nopsc (int fd , bool noppme , bool save , __u32 *result );

four arguments, one int coming back at ya. no cap. ✨

💅 ARGUMENTS 💅

• fd — the file descriptor of the nvme device 🦋 like, this is your ticket into the device, you gotta have it, don't show up empty-handed.
• noppme — Non-Operational Power State Permissive Mode Enable 🌈 a bool, so it's a yes-or-no moment, very binary, very demure of it.
• save — save the value across power states 💜 set this and your lil setting survives a power state change, she's not going anywhere.
• result — the command completion result from CQE dword0 👑 yep, dword0, exactly, that's where the answer shows up. it's a __u32 *, so, pointer moment.

🫶 RETURN 🫶

so here's the tea: you get the nvme command status if a response was received — check enum nvme_status_field for what those statuses mean, iykyk — or -1 with errno set otherwise. 😭 that's the "it didn't go how we wanted" path. fr fr.

bestie. if you're seeing -1, go read errno. it always tells you what went wrong. she's a gossip, let her spill. 💀
