STRUCT FW_BLOCK_INFO(9)

💖 struct fw_block_info(9) 💖

okay so bestie, welcome to the Kernel API Manual entry for struct fw_block_info — literally the block header for FW 🎀 (yes, that's the whole NAME, she's short and sweet, we love a minimal queen).

✨ SYNOPSIS ✨

here's the whole shape of her, no cap, copy it exactly:

struct fw_block_info {
    enum sst_ram_type       type;
    u32 size;
    u32 ram_offset;
    u32 rsvd;
 };

like… four fields and a dream 🦋 she's not doing the most, she's just doing her job.

🌸 Members 🌸

• type — the block ram type, and it's I/D 👑 (yes, that's literally how the manual writes it, we're not elaborating, we're respecting the source)
• size — the size of the block 📏 that's it, that's the field
• ram_offset — the offset in ram 🧚 where she sits in memory

ngl the struct up top also has a field called rsvd and this Members list ~does not~ say a single word about it 🙈 not me noticing, not me pointing it out — but like, we're keeping the record exactly as the manual gives it, so if you were hoping for lore on rsvd, the manual is giving mysterious main character energy 💅
