STRUCT NAND_MANUFACTURER_OPS(9)

✨ struct nand_manufacturer_ops(9) ✨

okay so bestie, welcome to the Kernel API Manual — this one's all about struct nand_manufacturer_ops, aka the NAND Manufacturer operations 💅 the vibe is: this is the little struct where a NAND vendor drops their own custom hooks so the core code can call into vendor-specific magic. iykyk 🧚

🌸 NAME 🌸

struct nand_manufacturer_ops — literally the NAND Manufacturer operations, no cap 🫶

---

💖 SYNOPSIS 💖

here's the whole struct, copied exactly, don't come for me:

struct nand_manufacturer_ops {
    void (*detect)(struct nand_chip *chip);
    int (*init)(struct nand_chip *chip);
    void (*cleanup)(struct nand_chip *chip);
    void (*fixup_onfi_param_page)(struct nand_chip *chip, struct
nand_onfi_params *p);
 };

heads up ✨ the fixup_onfi_param_page line wraps in the original — the second line starts with nand_onfi_params *p); and the closing brace sits at one leading space. keeping it exactly as it is, bestie 🎀

🦋 MEMBERS 🦋

• detect — this is the one that sniffs out the NAND memory organization and capabilities 🔍 it's giving detective main character energy, fr fr.
• init — sets up all the vendor specific fields (like the ->read_retry implementation) if there are any 💜 so like, if any — sometimes there just aren't, and that's fine.
• cleanup — okay so the ->init function may have allocated resources, and ->cleanup is literally here so vendor specific code can release those resources 🎀 cleanup crew, iconic.
• fixup_onfi_param_page — applies vendor specific fixups to the ONFI parameter page ✨ and the important part: this gets called after the checksum is verified. so the checksum happens first, then the fixups — don't flip that, bestie 😭

🍓 cute little sign-off: this one lives in ./drivers/mtd/nand/raw, dated October 2026, and the header up top is struct nand_...facturer_ops(9) 🫶 go forth and detect some NAND 💖
