✨ NAME ✨

enum nvme_bpinfo — this field indicates the boot partition information 👑

(that's it. that's the whole vibe. boot partition info, in enum form, slay.)

🦋 SYNOPSIS 🦋

enum nvme_bpinfo {
    NVME_BPINFO_BPSZ_SHIFT ,
    NVME_BPINFO_BRS_SHIFT ,
    NVME_BPINFO_ABPID_SHIFT ,
    NVME_BPINFO_BPSZ_MASK ,
    NVME_BPINFO_BRS_MASK ,
    NVME_BPINFO_ABPID_MASK ,
    NVME_BPINFO_BRS_NONE ,
    NVME_BPINFO_BRS_READ_IN_PROGRESS ,
    NVME_BPINFO_BRS_READ_SUCCESS ,
    NVME_BPINFO_BRS_READ_ERROR

};

look at her. ten whole constants. iconic. no cap, type them exactly like that or the compiler will simply not know her 😭

💖 Constants 💖

okay so these are the members, one by one, no skipping, we are NOT summarising today bestie 🫶

• NVME_BPINFO_BPSZ_SHIFT — the shift amount you use to get the boot partition size. shift it, girl.
• NVME_BPINFO_BRS_SHIFT — the shift amount you use to get the boot read status.
• NVME_BPINFO_ABPID_SHIFT — the shift amount you use to get the active boot partition ID.
• NVME_BPINFO_BPSZ_MASK — the mask that gets you the boot partition size. mask on, illuminate ✨
• NVME_BPINFO_BRS_MASK — the mask that gets you the boot read status.
• NVME_BPINFO_ABPID_MASK — the mask that gets you the active boot partition ID.
• NVME_BPINFO_BRS_NONE — no boot partition read operation requested. like, nothing's happening, we're just chilling 🛋️
• NVME_BPINFO_BRS_READ_IN_PROGRESS — boot partition read is in progress. hold on, she's working on it ⏳
• NVME_BPINFO_BRS_READ_SUCCESS — boot partition read completed successfully. ATE. no crumbs left. 🔥
• NVME_BPINFO_BRS_READ_ERROR — error completing the boot partition read. it's giving disaster, bestie 💀 scream, cry, check your bits.

real talk though: those four BRS_* values are the whole mood ring for a boot partition read — not requested, in progress, done, or broke. that's the status arc, and you're just reading it off the field 🎀

and that's the page!! go forth and read your boot partition information like the main character you are 👑💜
