nand_ecc_is_strong_enough(9)

✨ NAME ✨

nand_ecc_is_strong_enough — okay so this one literally just checks whether your chip configuration actually meets the datasheet requirements 💅 (yes, that's the whole vibe, and it's a Kernel API Manual moment, bestie 🫶)

---

🦋 SYNOPSIS 🦋

bool nand_ecc_is_strong_enough (struct nand_device *nand );

---

🌸 ARGUMENTS 🌸

• nand — the device you wanna check, no cap 🔍

---

💖 DESCRIPTION 💖

So here's the tea ☕ — if our configuration corrects A bits per B bytes, and the minimum required correction level is X bits per Y bytes, then we gotta make sure both of these are true, periodt:

1. A / B >= X / Y
2. A >= X

Requirement (1) is the one that ensures we can correct for the required bitflip density ✨

Requirement (2) is the glow-up that ensures we can correct even when all the bitflips get clumped together in the same sector 😭 like they're all showing up to the same party 🎀

Both conditions, bestie. Not one, not the other. Both. The vibe check fails if even one of them is off 💀
