okay so you're deep in libnvme land and you pulled up this page, which means you wanna meet a very specific little struct. welcome. this is the manual for struct nvme_mi_nvm_ss_health_status, and honestly? it's giving "subsystem management data structure" and I mean that in the most affectionate way possible. 🩺✨


πŸŽ€ NAME πŸŽ€

✨ SYNOPSIS ✨

🌸 Members 🌸

  • nss β€” NVM Subsystem Status. the moment of truth, the ~vibe check~ of the whole subsystem. πŸ‘‘
  • sw β€” Smart Warnings. it's literally in the name, she's smart and she's warning you. listen to her. 🚨
  • ctemp β€” Composite Temperature. yes bestie, we're taking her temperature. 🌑️
  • pdlu β€” Percentage Drive Life Used. how much of the drive's life is used up β€” the drive's screen time has been a lot, ngl. 😭
  • ccs β€” Composite Controller Status. controller status, but make it composite. πŸ¦‹
  • rsvd8 β€” Reserved. do not touch. not yours. reserved means reserved, fr fr. πŸ™ˆ

πŸ’€ quick reminder bestie: rsvd8 is Reserved, so leave it alone, and keep every field name and type exactly as they appear above β€” no renaming, no "fixing", no rearranging. the struct knows what it is. periodt.

that's the whole page!! short, sweet, and lowkey iconic. go forth and read your subsystem health like the main character you are. πŸ’œ
