NVME_INIT_SET_FEATURES_POWER_MEASUREMENT-LIBNVME3(2)

📦 version 3.2, in arch rolling

💅 nvme_init_set_features_power_measurement(9) — from the libnvme API manual, bestie 🎀

okay so picture this: it's a libnvme API manual page, the vibe is immaculate, and the function we're stanning today is nvme_init_set_features_power_measurement. yes that's a long name. yes she's worth it. ✨

🌸 NAME 🌸

nvme_init_set_features_power_measurement — literally just initializes a passthru command for Power Measurement, no cap

🦋 SYNOPSIS 🦋

void nvme_init_set_features_power_measurement (struct
libnvme_passthru_cmd *cmd , bool sv , __u8 act , __u8 pmts , __u16 smt ,
__u32 actsp );

so it returns void, meaning she does her thing and dips — no return value to obsess over 💅

✨ ARGUMENTS ✨

  • cmd — the passthru command you're gonna use, periodt 🫶
  • sv — Save value across power states. it's a bool, so like... yes or no, bestie 🌈
  • act — the Action (ACT). go check enum nvme_voltage_measurement_act for this one — and fr fr, the Power Measurement and Voltage Measurement Action field values are defined identically, so don't stress 👑
  • pmts — Power Measurement Type Select (PMTS), and heads up: this one only matters if act requests Start Power Measurements 🌸
  • smt — Stop Measurement Time (SMT), also only used if act requests Start Power Measurements. she's conditional, she's mysterious ✨
  • actsp — Action Specific (ACTSP) Command Dword 12 value. Dword 12. very specific. very iconic 💜

💖 DESCRIPTION 💖

she initializes the passthru command buffer for the Set Features command with FID value NVME_FEAT_FID_POWER_MEASUREMENT. that's the whole job. that's her main character moment. ⭐

ngl if you're here it's probably because you're building passthru commands by hand and you wanted the shortcut — and honestly? valid. 🧚

anyway bestie, that's the whole page — no bugs listed, no exit statuses, no environment variables, just pure vibes and one very specific command buffer setup. ate and left no crumbs 💅🔥
