hynix_get_majority(9)

💅 hynix_get_majority 💅

okay so bestie, welcome to hynix_get_majority(9) — literally the kernel API manual page for this one tiny function, and yes it lives in the Kernel API Manual section 9, and yes we're gonna read it together 🫶

---

✨ NAME ✨

hynix_get_majority — gets the value that's occurring the most in a given set of values. that's it. that's the whole job. icon behaviour honestly 👑

---

🌸 SYNOPSIS 🌸

int hynix_get_majority (const u8 *in , int repeat , u8 *out );

like. she takes three things and gives you back an int. we love a simple signature 💖

---

🎀 ARGUMENTS 🎀

• in — the array of values you wanna test. the vibes we're judging 🦋
• repeat — the size of the in array. so like, how many values are actually in there, bestie 📏
• out — pointer used to store the output value. this is where the winner gets written 💫

💜 DESCRIPTION 💜

so this function implements the 'majority check' logic — and the whole reason it exists is to overcome the unreliability of MLC NANDs when they're reading the OTP area that stores the read-retry parameters 😭 like the hardware is out here being flaky and this little function is the one holding it together.

it's based on a pretty simple assumption: if we repeat the same value several times and then take the one that's occurring the most, we should find the correct value. that's it. that's the algorithm. majority vote, no cap 🗳️✨

and then the manpage says, and I quote the energy: let's hope this dummy algorithm prevents us from losing the read-retry parameters 🙈 like it's literally described as a dummy algorithm in the source text and we're all just praying on it. no notes. main character energy fr fr 💀

highkey worth remembering: the function's own description calls this approach a simple assumption and a dummy algorithm — so nobody's out here claiming it's fancy. it's a hope-and-majority situation 🌈

okay that's the page!! it's giving kernel internals but make it cute 🧚 and for the record, this gem is from ./drivers/mtd/nand/raw, dated October 2026 — so yeah, shoutout to the source and version, mwah 💋💖
