nand_read_page_hwecc(9)

💅 nand_read_page_hwecc(9) 💅

okay so bestie, we're in the Kernel API Manual today and this page is genuinely iconic — it's giving "hardware does the ECC math so you don't have to" ✨

---

✨ NAME ✨

nand_read_page_hwecc — the [REPLACEABLE] hardware ECC based page read function 🎀

---

✨ SYNOPSIS ✨

int nand_read_page_hwecc (struct nand_chip *chip , uint8_t *buf , int
oob_required , int page );

---

✨ ARGUMENTS ✨

• chip — the nand chip info structure, like, the whole vibe of the chip lives in here 🫶
• buf — the buffer where the read data gets stored. that's the data's new home, no cap
• oob_required — the caller is saying "yes bestie i need the OOB data read to chip->oob_poi" 👑
• page — the page number you wanna read. pick one, any one 💅

---

✨ DESCRIPTION ✨

Not for syndrome calculating ECC controllers which need a special oob layout.

🚨 read that twice fr fr — if your controller is out here doing syndrome calculating ECC and needs its own special oob layout, this is NOT the function for you. wrong function, wrong vibe, respectfully 💀

and that's the page, bestie!! 🦋 this one came out of ./drivers/mtd/nand/raw, dated October 2026 — so go read the source, stay hydrated, and remember: hardware ECC page reads only, syndrome-controller girlies need a different function 💖⭐🍓
