💅 nvme_init_get_features_perf_characteristics(9) — libnvme API manual ✨

okay so bestie, grab your iced coffee 🍓 because we're reading the <rainbow>libnvme API manual</rainbow> together and this page is literally about one very long function name: nvme_init_get_features_perf_characteristics. yes the header up top gets truncated to nvme_init_g...racteristics(9) because even the manpage index was like "girl that's too many letters" 😭 but we're gonna say the whole thing, periodt.

✨ NAME ✨

nvme_init_get_features_perf_characteristics — sets up the passthru command for Get Features - Performance Characteristics. it's giving "prep the envelope before you mail it" 💌

---

🌸 SYNOPSIS 🌸

void nvme_init_get_features_perf_characteristics (struct libnvme_passthru_cmd *cmd, enum nvme_get_features_sel sel, __u8 attri, struct nvme_perf_characteristics *data);

that's it. that's the whole vibe check. returns void, so like… it doesn't even hand you back a status code, it just does the thing 🫶

---

🎀 ARGUMENTS 🎀

• cmd — the passthru command you're gonna use. this is the lil vessel you're filling up, so hand it over and let the function do its thing 💅
• sel — which type of attribute you want returned. check enum nvme_get_features_sel for your options, iykyk ✨
• attri — the Attribute Index, aka ATTRI (yes, in all caps, it's that girl 👑)
• data — the buffer where the returned struct nvme_perf_characteristics lands. this is where the tea gets delivered 🍵

---

🦋 DESCRIPTION 🦋

so what does it actually do? it initializes the passthru command buffer for the Get Features command, with the FID value NVME_FEAT_FID_PERF_CHARACTERISTICS. that's it, that's the whole job — no cap, no extra side quests, no hidden lore 🌈

think of it as setting up the group chat invite before anybody actually replies. the command buffer is prepped, the FID is locked in, and you're ready to go 💖

heads up bestie: this initializes the buffer, it does not run the command for you. don't @ me when you forget to actually submit it 💀

and that's the page!! main character energy from start to finish 💜 this was the libnvme API manual — dated October 2026 — and the footer was out here trying to spell the whole function name again and lowkey failing (nvme_init_get_features_perf_charnvme_init_g...racteristics(9) 😭 iconic honestly). mwah, go forth and init those features 🧚‍♀️⭐
