nvme_init_set_features_rrl(9)

💅 nvme_init_set_features_rrl(9) — like, the libnvme API manual, bestie 🎀

okay so this is a page straight out of the libnvme API manual, and it's about one tiny little function that sets up your passthru command for the Read Recovery Level. yes, that Read Recovery Level. it's giving "small function, big job" energy and honestly? we stan. ✨

🌸 NAME 🌸

nvme_init_set_features_rrl — Initialize passthru command for Read Recovery Level. that's it, that's the whole gig. she initializes, she sets up, she slays. 👑

---

⭐ SYNOPSIS ⭐

void nvme_init_set_features_rrl (struct libnvme_passthru_cmd *cmd , bool
sv , __u16 nvmsetid , __u8 rrl );

like, four arguments, no return value (void, so she gives you nothing back and that's on purpose, periodt). 💅

---

🦋 ARGUMENTS 🦋

• cmd — the Passthru command to use. this is your main character struct, struct libnvme_passthru_cmd *, and she's the one getting all set up. 🫶
• sv — Save value across power states. it's a bool, so it's a yes-or-no vibe check. ✨
• nvmsetid — NVM set id. it's a __u16, so it's a little 16-bit friend telling you which set we're talking about. 🌸
• rrl — Read recovery level setting. it's a __u8, so smol but mighty. 🧚

💖 DESCRIPTION 💖

so what does she actually do? she Initializes the passthru command buffer for the Set Features command with FID value NVME_FEAT_FID_RRL. 💫

that's literally the whole thing — she gets that command buffer ready for the Set Features command, and the FID value she uses is NVME_FEAT_FID_RRL. no cap, that's the plot. 🔥

heads up bestie: she only initializes the buffer — the page doesn't say she submits it, so don't come for me, i'm just reading the manual fr fr. 🙈

---

okay that's the page!! and before you go — this whole thing is from the libnvme API manual, dated October 2026, so give her a little respect, she's from the future. 🦋 bye bestie, go initialize some passthru commands responsibly 😭💜🌈
