📦 version 3.2, in arch rolling

👑 NVME-RPMB-WRITE-C(1) — the nvme manual, but make it cute 💅

okay bestie, so this page lives in the NVMe Manual and it's literally about nvme-rpmb-write-config, the little icon that writes your RPMB device configuration block. buckle up 🎀

✨ NAME ✨

nvme-rpmb-write-config — Write the RPMB device configuration block 🦋

✨ SYNOPSIS ✨

nvme [<global-options>] rpmb write-config <device>
                        [--msgfile=<data-file> | -f <data-file>]
                        [--msg=<data> | -d <data>]
                        [--keyfile=<key-file> | -g <key-file>]
                        [--key=<key> | -k <key>]

✨ DESCRIPTION ✨

so this command writes 512 bytes of device configuration block data to RPMB target 0 of the NVMe device 💖 and it's authenticated with the key you previously programmed with nvme rpmb program-key — no key, no entry, iykyk 🔑

the <device> parameter is mandatory, bestie, and you gotta give it an NVMe character device (ex: /dev/nvme0). like, that's the whole vibe check. no cap. 🌸

✨ OPTIONS ✨

  • -k <key>, --key=<key>, -g <key-file>, --keyfile=<key-file> — the authentication key you already programmed with nvme rpmb program-key for target 0 🔐 you can drop it straight on the command line with --key or -k, or read it from a file with --keyfile or -g. your choice, main character 💅
  • -f <data-file>, --msgfile=<data-file> — the name of the file the configuration block data is read from 📂
  • -d <data>, --msg=<data> — provides the configuration block data directly on the command line instead of reading it from a file 🫶

✨ GLOBAL OPTIONS ✨

these ones are defined at the top-level nvme command, and they're available to this subcommand too — so they're like, the group chat everyone's in 🌈

  • --dry-run — print the command that would be executed, but do not actually execute it. all the vibes, zero commitment 🙈
  • --no-ioctl-probing — disable probing for 64-bit IOCTL support ✨
  • --no-retries — disable retry logic on transient errors 💀
  • -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 ⭐
  • --output-format-version=<version> — select the output format version. version 1 uses the original field naming, while version 2 (the default) provides more consistent and script-friendly field names. other versions are rejected, periodt 🚫
  • --quiet — suppress informational messages. errors are still reported, and --quiet cancels any --verbose for the library log level 🤫
  • --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) ⏳
  • -v, --verbose — increase the level of detail in the output. may be specified multiple times to further increase verbosity 📈
also, these options can be set as machine-wide defaults in nvme-cli.conf(5) — and a command-line flag always overrides the file, no debate 👑

✨ EXAMPLES ✨

  • write configuration data block from config.bin file 🔥
# nvme rpmb write-config /dev/nvme0 -f config.bin -k 'SecretKey'
