💅 libnvme_mi_mi_pda_write_zeroes(9) — libnvme API manual ✨

okay so bestie, welcome to the libnvme API manual page for libnvme_mi_m...write_zeroes(9) — yes the title gets truncated like that in the header, it's giving "character limit on the group chat name", but we move 🫶

🌸 NAME 🌸

libnvme_mi_mi_pda_write_zeroes — Clear a range of the NVMe-MI Persistent Data Area (PDA) to 0h

like, literally wipe a chunk of the PDA to zero. iconic destructive energy 💀

✨ SYNOPSIS ✨

int libnvme_mi_mi_pda_write_zeroes (struct libnvme_mi_ep *ep , enum
nvme_mi_pda_dformat dformat , __u32 dofst , __u32 dlen );

it returns an int, it takes four things, no cap 🎀

🦋 ARGUMENTS 🦋

  • ep — the endpoint for MI communication. your connection girlie, the whole vibe of the convo runs through her 💖
  • dformat — the data format to use for dofst and dlen, see enum nvme_mi_pda_dformat. basically the units system so the two numbers below actually mean something 🌈
  • dofst — starting offset, in units of dformat, into the PDA to clear. where the zeroing begins, main character starting point 👑
  • dlen — length, in units of dformat, of the PDA to clear starting at dofst. how far the zeroes go from there, periodt 💅
ngl the units thing matters: dofst and dlen are both measured in dformat, not raw bytes. read the enum, bestie 🧚

🔥 DESCRIPTION 🔥

Performs an NVMe-MI PDA Write Zeroes command.

that's it, that's the whole function. it clears a range of the NVMe-MI Persistent Data Area (PDA) to 0h, and it does it via the NVMe-MI PDA Write Zeroes command. lowkey elegant 🌸

⭐ RETURN ⭐

The nvme command status if a response was received (see enum nvme_status_field) or a negative error code otherwise.

so: response came back → you get the nvme command status; no response → negative error code. check it, don't just ignore it, i'm begging 😭

k that's the whole page, mwah 💖 — brought to you by the libnvme API manual, October 2026 issue, stamped with that libnvme_mi_mi_pda_write_libnvme_mi_m...write_zeroes(9) footer energy because even the footer got truncated. slay 🎀✨🦋
