💅 nvme_init_set_features_plm_window — nvme_init_s...s_plm_window(9)

okay so welcome to the libnvme API manual, bestie 💖 this one's a sweet little function page from the libnvme crew and honestly? she's short, she's specific, she slays.

✨ NAME ✨

nvme_init_set_features_plm_window — Initializes (wait for it) the passthru command for Predictable Latency Mode Window. yes that's a real thing and yes it's iconic 👑

🦋 SYNOPSIS 🦋

void nvme_init_set_features_plm_window (struct libnvme_passthru_cmd *cmd
, bool sv , __u16 nvmsetid , enum nvme_feat_plm_window_select wsel );

literally just hand her four things and she'll do the rest 🫶

🎀 ARGUMENTS 🎀

  • cmd — the Passthru command you're gonna use. this is the canvas, the blankie, the thing she fills in for you ✨
  • sv — Save value across power states. a bool, so it's giving yes/no energy. should your setting survive a power cycle? that's the whole question 💀
  • nvmsetid — the NVM Set Identifier (__u16). which NVM set we're talking about, bestie 🔥
  • wsel — Window Select. an enum nvme_feat_plm_window_select, no cap. pick your window 🌸

🌈 DESCRIPTION 🌈

so what does she do? she initializes the passthru command buffer for the Set Features command, with the FID value NVME_FEAT_FID_PLM_WINDOW. that's it. that's the whole vibe check. she sets up the buffer so the command is ready to go, and then you take it from there 💅

ngl the whole job is "prepare the thing" — no hidden tricks, no surprises, just clean predictable-latency-window setup energy 🧚

that's the page, bestie — go forth and configure those windows ✨

shoutout to the libnvme API manual for hosting this lil icon, and to October 2026 for the timestamp — mwah, love u, bye 🎀💖
