💅 nvme_init_set_features_rate_limiting(9) — libnvme API manual 🎀

okay so bestie, you're in the libnvme API manual, section 9, and the star of this page is nvme_init_set_features_rate_limiting. it's giving "glow-up your passthru buffer" energy and honestly? iconic. ✨

✨ NAME ✨

nvme_init_set_features_rate_limiting — Initialize passthru command for Rate Limiting 🌈

like, that's literally her whole job. she sets up the passthru command so you can go do Rate Limiting things. no cap. 💅

---

🦋 SYNOPSIS 🦋

void nvme_init_set_features_rate_limiting (struct libnvme_passthru_cmd
*cmd , bool sv , __u8 target , __u16 tid , struct
nvme_rate_limiting_data *data );

she returns void btw, so don't go looking for a return value, she's not that kind of function 🫶

---

🌸 ARGUMENTS 🌸

• cmd — the Passthru command to use. this is the buffer she's gonna initialize, so hand her a good one bestie 💖
• sv — Save value across power states. it's a bool, so it's a yes/no vibe check ⭐
• target — Target of the rate limits setting, see enum nvme_rate_limiting_target. this is the __u8 that says where the rate limiting is happening 👑
• tid — Target Identifier for the target specified by target. a __u16, and yes it pairs with target like the matching besties they are 🎀
• data — User address of the Rate Limiting data buffer, see struct nvme_rate_limiting_data. this is the actual payload, the main character of the whole operation 💜

---

🔥 DESCRIPTION 🔥

okay so what she actually does: she Initializes the passthru command buffer for the Set Features command with FID value NVME_FEAT_FID_RATE_LIMITING. that's it, that's the whole serve. she's not doing the ioctl for you, she's prepping the buffer so it's all cute and ready to go. periodt. 💅

ngl bestie, this is a setup function — the passthru command buffer is what gets filled in, so make sure your cmd is valid before you hand it over. 🙈

💫 SEE ALSO 💫

so the page doesn't spell out a separate SEE ALSO list, but it does point you at two things, and you should absolutely go read them:

• enum nvme_rate_limiting_target — for the target argument 🌸
• struct nvme_rate_limiting_data — for the data argument 🦋

---

and that's the page, bestie! 🥳 this absolute gem comes to you from the libnvme API manual, dated October 2026 — go off and rate-limit responsibly, mwah 💋💖✨
