💖 nvme_init_zns_append(9) 💖

okay bestie, so this is a page from the libnvme API manual — yes, section 9, kernel/API territory, very main character of it — and it's all about nvme_init_zns_append, aka "Initialize passthru command to append data to a zone". 🎀 Stick around, it's literally a five second read and it slays.

✨ NAME ✨

nvme_init_zns_append — Initialize passthru command to append data to a zone 🌸

🦋 SYNOPSIS 🦋

void nvme_init_zns_append (struct libnvme_passthru_cmd *cmd , __u32 nsid
, __u64 zslba , __u16 nlb , __u16 control , __u16 cev , __u16 dspec ,
void *data , __u32 data_len , void *metadata , __u32 metadata_len );
no cap, that's a lot of arguments. it returns void tho so at least she's low maintenance 💅

💜 ARGUMENTS 💜

  • cmd — the passthru command to use. this is the blank canvas you're filling in, bestie 🖌️
  • nsid — the Namespace ID. which namespace we're talking to ✨
  • zslba — Zone start logical block address. where the zone begins, fr fr 📍
  • nlb — Number of logical blocks. how many blocks we're working with 🔢
  • control — the Upper 16 bits of cdw12. yep, just those top bits 👑
  • cev — Command Extension Value 🧚
  • dspec — Directive Specific 🎯
  • data — Userspace address of the data buffer. your actual payload goes here 💾

🌈 DESCRIPTION 🌈

Initializes the passthru command buffer for the ZNS Append command. that's it, that's the whole vibe — it sets up cmd so it's ready to do the ZNS Append thing. obsessed 😭

heads up: she's a void function, so don't go looking for a return value. it just does the init and dips 💀

and that's the whole page, bestie — literally every argument accounted for, nothing skipped, we ate that 🫶
