💖 NAME 💖

Okay so this is libnvme(9), the API manual, and today's main character is struct tcg_l0_geometry — the Geometry Reporting feature. Its feature code is 0x0003. Slay.

✨ SYNOPSIS ✨

Here's the struct in all its glory, no cap:

struct tcg_l0_geometry {
    __u8 align;
    __u8 rsvd1[7];
    __be32 logical_block_size;
    __be64 alignment_granularity;
    __be64 lowest_aligned_lba;
 };

• align — the flags, bestie; see enum tcg_l0_geometry_flags.
• rsvd1 — reserved. literally just vibing in the padding.
• logical_block_size — the logical block size, periodt.
• alignment_granularity — the alignment granularity, iykyk.
• lowest_aligned_lba — the lowest aligned LBA.

🌸 Description 🌸

This is TCG Opal SSC 2.02, section 3.1.1.4. That's the whole lore.
