💅 xnvme_tests_map-mem_map_unmap(1) — aka the xNVMe manual, bestie edition 🎀

okay so you found the xnvme_tests_map-mem_map_unmap page in the xNVMe manual and you're like "what is this" — don't worry, I got you. sit down, hydrate, let's go ✨

🌸 NAME 🌸

xnvme_tests_map-mem_map_unmap — it maps and unmaps a buffer 'count' times, of size [1, 2^count]. literally that's the whole personality 💅

🦋 SYNOPSIS 🦋

xnvme_tests_map mem_map_unmap <uri> [<args>]

that's it, that's the shape of it. xnvme_tests_map is the command, mem_map_unmap is the sub-command, then your <uri> and then whatever optional <args> you feel like sprinkling in 🫶

💖 DESCRIPTION 💖

Map and unmap a buffer 'count' times of size [1, 2^count]. no cap, that is genuinely what it does — it's a stress-y little map/unmap loop and it's kind of iconic for it 🔥

👑 REQUIRED 👑

these ones are not optional, bestie. you need them. no skipping 🙈

  • <uri> — the Device URI, like '/dev/nvme0n1', '0000:01:00.1', '10.9.8.1.8888', or '\.PhysicalDrive1'. yes, all of those, character for character, I don't make the rules ✨
  • --count NUM — use the given 'NUM' as the count. that's the number of times it does the map/unmap thing 💫

🎀 OPTIONAL 🎀

the little extras, the accessories to the outfit. all optional, all cute 🌈

  • [ --subnqn STRING ] — the Subsystem NQN of the NVMe over Fabrics endpoint, e.g. 'nqn.2022-06.io.xnvme:ctrlnode1'. for the fabrics girlies 🧚
  • [ --hostnqn STRING ] — the host NQN to use when connecting to NVMe over Fabrics controllers 🦋
  • [ --be STRING ] — the xNVMe backend, e.g. 'linux', 'spdk', 'fbsd', 'macos', 'posix', 'windows'. pick your fighter 💅
  • [ --dev-nsid 0xNUM ] — Namespace Identifier for Device Handle. note the 0x, it's giving hex and we respect it ⭐
  • [ --admin STRING ] — the xNVMe admin. command-interface, e.g. 'nvme', 'block' 👑
  • [ --mem STRING ] — the xNVMe buffer/memory manager 🌸
  • [ --direct NUM ] — Bypass layers. yes, all of them, go off 😭
  • [ --help ] — Show usage / help. your bestie when you're lost 🫶
