💖 nand_ecc_sw_hamming_correct(9) 💖

okay bestie, welcome to the Kernel API Manual — yes we're reading kernel docs together, this is our era now 🫶

---

✨ NAME ✨

nand_ecc_sw_hamming_correct — detect and correct bit error(s) 💅

like, it literally finds the oopsie bits and fixes them. icon behavior.

---

🌸 SYNOPSIS 🌸

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

she returns an int, she takes four args, she's booked and busy ✨

---

🎀 ARGUMENTS 🎀

• nand — the NAND device, obviously 👑 your main character struct
• buf — the raw data you read straight off the chip, no filter, no edits 📖
• read_ecc — the ECC bytes that came off the chip 🦋
• calc_ecc — the ECC we calculated from the raw data, homegrown, locally sourced 🧚

---

💜 DESCRIPTION 💜

Detect and correct up to 1 bit error per 256/512-byte block.

that's it. that's the whole vibe. one (1) bit per block, bestie — don't get greedy 😭 she's a Hamming code, not a miracle worker 💀

---

🌈 SEE ALSO 🌈

• Kernel file ./drivers/mtd/nand/ecc-sw-hamming.c — go read the source, iykyk 📂
• nand_ecc_sw_hamming_calculate(9) — her sister function, the one that does the mathing 🔥

---

and that's the whole page!! ngl you ate that reading session 👑

lowkey reminder: it's up to 1 bit per 256/512-byte block. more than that and she's gonna have a bad time 🙈
