nvme_init_s...resv_persist(9)

💅 nvme_init_set_features_resv_persist(9) — like, the libnvme API manual, bestie ✨

okay so real talk, this whole page lives in the libnvme API manual and it's about one (1) little function that sets up a passthru command. that's it. that's the vibe. let's get into it 🫶

---

🌸 NAME 🌸

nvme_init_set_features_resv_persist — initializes the passthru command for Reservation Persistence. yes, that's the whole name, no she did not shorten it 💅

---

✨ SYNOPSIS ✨

here's the signature, copy it exactly, no cap:

void nvme_init_set_features_resv_persist (struct libnvme_passthru_cmd
*cmd , __u32 nsid , bool sv , bool ptpl );

it returns void, so like… she does the work and doesn't even ask for a thank-you. main character energy fr fr 👑

---

🎀 ARGUMENTS 🎀

every single one, in order, no skipping:

• cmd — the passthru command you're gonna use. this is the lil vessel she fills in 🫙
• nsid — the Namespace ID. which namespace we're talking to, obviously 💫
• sv — Save value across power states. a bool, so it's a yes/no situation ⚡
• ptpl — Persist Through Power Loss. also a bool. the name literally says what it does, iconic 🌈

---

🦋 DESCRIPTION 🦋

so what does she do? she initializes the passthru command buffer for the Set Features command, with the FID value NVME_FEAT_FID_RESV_PERSIST. that's the whole assignment. she shows up, she sets the buffer up correctly, she leaves. ate and left no crumbs 💀✨

lowkey the entire point is that you don't have to hand-build that buffer yourself — she already knows the FID you need. iykyk 🧚
