nand_ecc_sw_bch_correct(9)

🌸 NAME 🌸

okay so bestie, this is nand_ecc_sw_bch_correct(9) from the Kernel API Manual — the page for the function whose whole job is Detect, correct and report bit error(s). It’s giving “NAND caretaker energy,” fr fr. 💅✨

✨ SYNOPSIS ✨

Here’s the signature, exactly as it appears — no touchies:

int nand_ecc_sw_bch_correct (struct nand_device *nand , unsigned char
       *buf , unsigned char *read_ecc , unsigned char *calc_ecc );

🎀 ARGUMENTS 🎀

• nand — the NAND device, aka the main character of this whole operation 👑
• buf — raw data read from the chip, fresh off the hardware 🍓
• read_ecc — the ECC bytes from the chip, literally what was read 💖
• calc_ecc — the ECC calculated from the raw data, the math-y bestie 🧚

🌈 DESCRIPTION 🌈

So what does it do? It detects and corrects bit errors for a data block. That’s the whole vibe: detect, correct, report. It’s lowkey the cleanup crew for your NAND data block, and yes, the page really does say bit error(s) with the parentheses — we stan precision. 💀✨
