nand_maximize_ecc(9)

💖 nand_maximize_ecc(9) 💖

hey bestie, welcome to the Kernel API Manual page for nand_maximize_ecc(9) — manual name folded in right here so we can skip the boring header line and get straight to the explanation. 🫶

---

🌸 NAME 🌸

• nand_maximize_ecc — choose the max ECC strength available ✨

---

✨ SYNOPSIS ✨

int nand_maximize_ecc (struct nand_chip *chip , const struct
       nand_ecc_caps *caps , int oobavail );

---

🎀 ARGUMENTS 🎀

• chip — nand chip info structure 💖
• caps — ECC engine caps info structure ✨
• oobavail — OOB size that the ECC engine can use 🎀

---

🦋 DESCRIPTION 🦋

okay so the whole point is literally this: choose the max ECC strength that is supported on the controller, and can fit within the chip's OOB. On success, the chosen ECC settings are set. that's the vibe — max ECC strength, no cap, but it still has to fit the OOB budget. 💅
