🌸 NAME 🌸

nvme_init_format_nvm — initialize the passthru command for Format NVM 🧚

✨ SYNOPSIS ✨

, __u8 lbaf , enum nvme_cmd_format_mset mset , enum nvme_cmd_format_pi
pi , enum nvme_cmd_format_pil pil , enum nvme_cmd_format_ses ses );

she takes a void, she returns nothing, and she still manages to do the most 💅 no cap, copy that signature exactly, iykyk.

🦋 ARGUMENTS 🦋

  • cmd — the passthru command you're working with, like, this is the lil vessel she fills up 🫙
  • nsid — the Namespace ID you're formatting, this is __u32 so she's got room to breathe
  • lbaf — the logical block address format (it's __u8, tiny but iconic)
  • mset — metadata settings, and the options are extended or separated — pick your fighter ⚔️
  • pi — protection information type, lowkey important, don't skip her
  • pil — protection information location, aka beginning or end, choose wisely 📍
  • ses — secure erase settings, bestie this is literally the "how thoroughly are we wiping this" knob 💀

👑 DESCRIPTION 👑

Initializes the passthru command buffer for the Format NVM command 🔥

like, that's it, that's the whole job — she preps the buffer so the Format NVM command is ready to go, and then she dips (she's a void, she returns nothing, main character energy fr fr) ⭐

ngl bestie, always double-check your lbaf, mset, pi, pil, and ses before you send this off — this is a format command, the data does not come back 😭🙈
