✨ nvme-feat-power-thresh(1) ✨

okay so bestie, we're deep in the NVMe Manual today and this is the page for nvme-feat-power-thresh — the glow-up command for getting and setting the power threshold feature 🎀

🌸 NAME 🌸

nvme-feat-power-thresh — get and set the power threshold feature. that's it, that's the vibe 💅

---

🦋 SYNOPSIS 🦋

nvme [<global-options>] feat power-thresh <device>
                        [--pwrth=<pwrth> | -p <pwrth>] [--pvtht=<pvtht> | -t <pvtht>]
                        [--sel=<select> | -S <select>] [--save | -s]

💖 DESCRIPTION 💖

So. This command gets and sets the power threshold feature. Lowkey iconic.

The <device> parameter is mandatory — you literally cannot skip it, bestie. It can be either:

• the NVMe character device, like /dev/nvme0 ✨
• or a namespace block device, like /dev/nvme0n1 🫶

Here's the tea on how it behaves: if you specify any of the setting options (--pwrth or --pvtht), the command updates the power threshold configuration. But if you don't specify either of them? It just retrieves and displays the current configuration for you. no cap, it's that simple 💜

On success it returns 0 — any error code otherwise. periodt.

---

🎀 OPTIONS 🎀

• -p <pwrth>, --pwrth=<pwrth> — Power Threshold. Specifies the power threshold value to be applied to the controller 🔥
• -t <pvtht>, --pvtht=<pvtht> — Power Threshold Type. Specifies the type of power threshold, like static or dynamic threshold 🦋
• -S <select>, --sel=<select> — Select (SEL): this field specifies which value of the attributes to return in the provided data:
  • 0 — current — Current
  • 1 — default — Default
  • 2 — saved — Saved
  • 3 — supported — Supported capabilities ⭐
• -s, --save — Save the attribute so that it persists through all power states and resets 💾✨

👑 GLOBAL OPTIONS 👑

The following options are defined at the top-level nvme command and are available to this subcommand — they're the main character energy that follows you everywhere:

• --dry-run — Print the command that would be executed, but do not actually execute it. look, don't touch 🙈
• --no-ioctl-probing — Disable probing for 64-bit IOCTL support.
• --no-retries — Disable retry logic on transient errors. one shot, no second chances 💀
• -o <fmt>, --output-format=<fmt> — Set the reporting format to normal, tabular, 'json, or binary. Only one output format may be used at a time. pick one, bestie ✨
• --output-format-version=<version> — Select the output format version. Version 1 uses the original field naming, while version 2 (default) provides more consistent and script-friendly field names. Other versions are rejected 🚫
• --quiet — Suppress informational messages. Errors are still reported, and --quiet cancels any --verbose for the library log level. shhh 🤫
• --set-options=<key=value>[,<key=value>...] — Set libnvme library options for this invocation. Supported keys are force-4k, mi-probe-enabled, test-base-dir and test-sysfs-dir.
• --timeout=<ms> — Set the timeout for the command in milliseconds. infinite or -1 waits without a time limit (0xffffffff). time is fake anyway ⏳
• -v, --verbose — Increase the level of detail in the output. May be specified multiple times to further increase verbosity. say it louder for the people in the back 📢

These options can also be set as machine-wide defaults in nvme-cli.conf(5). A command-line flag always overrides the file — CLI stays winning, fr fr 👑

🌈 EXAMPLES 🌈

1. Has the program issue a feat power-thresh to get the current configuration:

# nvme feat power-thresh /dev/nvme0

2. Has the program issue a feat power-thresh to set power threshold with saving enabled:

# nvme feat power-thresh /dev/nvme0 --pwrth=30 --pvtht=1 --save
