NVME_INIT_SET_FEATURES_POWER_LIMIT-LIBNVME3(2)

📦 version 3.2, in arch rolling

💅 nvme_init_set_features_power_limit

okay bestie, welcome to the libnvme API manual — yes that's the manual name, and yes we're gonna get through this together, it's genuinely not that deep. this one is a little C function called nvme_init_set_features_power_limit, and honestly? she's giving setup girlie. she doesn't do the thing, she just gets the command buffer all cute and ready so the thing can happen. main character energy but make it infrastructure. ✨

🎀 NAME 🎀

nvme_init_set_features_power_limit — initialize the passthru command for Power Limit 💖

✨ SYNOPSIS ✨

void nvme_init_set_features_power_limit (struct libnvme_passthru_cmd
*cmd , bool sv , __u8 pls , __u16 plv );

that's the whole signature, no cap. void return, four args, she takes what she needs and gives nothing back (emotionally). 🫶

🌸 ARGUMENTS 🌸

  • cmd — the passthru command you're gonna use. this is the canvas, the blank notes app, the little vessel your command lives in. 🎀
  • sv — save value across power states. a bool, so it's a yes-or-no situation, very "do you want me to remember this or not" vibes. 🔥
  • pls — Power Limit Scale (PLS). it's a __u8, so keep it smol. a little scale-y guy. 🦋
  • plv — Power Limit Value (PLV). this one's a __u16, so she's got a bit more room to be loud. 💜

💫 DESCRIPTION 💫

so what does she actually do?? she initializes the passthru command buffer for the Set Features command, with the FID value set to NVME_FEAT_FID_POWER_LIMIT. that's it. that's the whole job. she's the pre-game playlist, not the party. 🎵

like — she sets up the buffer so that when you actually fire the command off, it's already dressed and ready with the right feature identifier. no guessing, no "wait which FID was it again", she handles it. iconic behavior tbh. 👑

ngl, this is a setup function — it does not send anything to the device for you. don't @ me, that's just what "initialize the passthru command buffer" means, bestie. 🙈

and that's the whole page!! tysm for reading, you ate that fr fr 🍓

sign-off time: this little masterpiece comes from the libnvme API manual, and it's dated October 2026 — yes, future-dated, she's ahead of her time 💅✨🧚‍♀️
