💅 libnvme(9) — the one about the lockdown log, bestie

okay so real talk, this is libnvme(9), the API manual, and today's main character is an enum. yes an enum. don't scroll, it's actually important 🫶

---

✨ NAME ✨

enum nvme_lockdown_log_enhanced_cfia — literally the Command and Feature Lockdown Log Page, Enhanced edition, specifically the Command and Feature Identifier Attributes part (CFIA for short, iykyk) 🌸

---

🎀 SYNOPSIS 🎀

here's the whole vibe, no cap:

enum nvme_lockdown_log_enhanced_cfia {
    NVME_LOCKDOWN_LOG_ENHANCED_CFIA_SS_SHIFT ,
    NVME_LOCKDOWN_LOG_ENHANCED_CFIA_SS_MASK ,
    NVME_LOCKDOWN_LOG_ENHANCED_CFIA_CS_SHIFT ,
    NVME_LOCKDOWN_LOG_ENHANCED_CFIA_CS_MASK

};

four constants, that's the whole squad 💜

---

🌈 Constants 🌈

• NVME_LOCKDOWN_LOG_ENHANCED_CFIA_SS_SHIFT — the shift amount you use to get the Scope Selected (SS). that's it, that's the job ✨
• NVME_LOCKDOWN_LOG_ENHANCED_CFIA_SS_MASK — the mask to get SS. masking era fr fr 🎭
• NVME_LOCKDOWN_LOG_ENHANCED_CFIA_CS_SHIFT — the shift amount to get the Contents Selected (CS). shift it, slay it 💅
• NVME_LOCKDOWN_LOG_ENHANCED_CFIA_CS_MASK — the mask to get CS. last one, and she ate 👑

lowkey the pattern here is so satisfying: shift + mask for SS, shift + mask for CS. iconic symmetry, no notes 🦋

and that's the whole page, bestie — four constants and a little bit of bit-manipulation main character energy. go mask something 💖
