STRUCT NAND_OP_INSTR(9)

✨ struct nand_op_instr(9) ✨

okay so bestie, welcome to the Kernel API Manual — we're talking about struct nand_op_instr today, aka the literal instruction object of the NAND world. it's giving "one tiny struct, so much responsibility" and honestly? iconic. 💅

🌸 NAME 🌸

struct nand_op_instr — Instruction object, no cap. that's it, that's the whole vibe. 🎀

🦋 SYNOPSIS 🦋

here's the shape of it, bestie — copy it exactly, don't freestyle:

struct nand_op_instr {
    enum nand_op_instr_type type;
    union {
      struct nand_op_cmd_instr cmd;
      struct nand_op_addr_instr addr;
      struct nand_op_data_instr data;
      struct nand_op_waitrdy_instr waitrdy;
    } ctx;
    unsigned int delay_ns;
 };

💖 Members 💖

• type — literally the instruction type. that's the whole job. 🔥
• ctx — the extra data that comes attached to the instruction. and here's the thing, bestie: you have to use the appropriate element depending on type. like, don't just grab any of them, that's not the move 🙈
• ctx.cmd — use it if type is NAND_OP_CMD_INSTR. easy. ✨
• ctx.addr — use it if type is NAND_OP_ADDR_INSTR. 🎀
• ctx.data — use it if type is NAND_OP_DATA_IN_INSTR or NAND_OP_DATA_OUT_INSTR. both of those, yes. 👑
• ctx.waitrdy — use it if type is NAND_OP_WAITRDY_INSTR. 🦋
• delay_ns — the delay the controller should apply after the instruction has been issued on the bus. most modern controllers have internal timings control logic, and in that case the controller driver can just ignore this field. so like... it's there if you need it, no pressure 🌸
