✨ nand_op_parser_exec_op(9) ✨

okay bestie, welcome to the Kernel API Manual 🌸 this one's about nand_op_parser_exec_op and honestly it's giving "the middle-manager of NAND operations" and I mean that with love 💅

🎀 NAME 🎀

nand_op_parser_exec_op — the exec_op parser, aka the girl who reads the patterns and makes the split happen ✨

🦋 SYNOPSIS 🦋

int nand_op_parser_exec_op (struct nand_chip *chip , const struct
nand_op_parser *parser , const struct nand_operation *op , bool
check_only );

💖 ARGUMENTS 💖

  • chip — the NAND chip, the main character of this whole situation 👑
  • parser — the patterns description, handed to you by the controller driver 🫶
  • op — the NAND operation we're trying to address, like the actual task on the group chat 📋
  • check_only — when true, the function only checks if op can be handled but does not execute the operation. so it's a vibe check, not a full send 🙈

🌈 DESCRIPTION 🌈

okay so this is a helper function, and its whole personality is "ease integration of NAND controller drivers that only support a limited set of instruction sequences" 😌 the supported sequences are described in parser, and the framework takes care of splitting op into multiple sub-operations (if required) and passes them back to the ->exec callback of the matching pattern — but only if check_only is set to false. like, if you said check only, she's not gonna execute anything, respect the boundary 💅

NAND controller drivers should call this function from their own ->exec_op implementation. that's the assignment, no cap 📝

Returns 0 on success, a negative error code otherwise 🔥 and a failure can be caused by an unsupported operation (none of the supported patterns is able to handle the requested operation), or an error returned by one of the matching pattern->exec hook. so basically two ways to not slay 😭

🧚 SEE ALSO 🧚

Kernel file ./drivers/mtd/nand/raw/nand_base.c — and here's the full squad, every single one, because we don't leave anyone out of the group chat 💜

that's the whole page bestie, every last crumb 🍓 this came from ./drivers/mtd/nand/raw, dated October 2026 — so go forth, call it from your ->exec_op, and remember: check first, execute later 💅✨🎀
