omap_compare_ecc(9)

okay bestie, this is the Kernel API Manual page for omap_compare_ecc(9) — the NAND ECC compare-and-correct situation, and it’s lowkey iconic ✨.

🌸 NAME 🌸

omap_compare_ecc — Detect (2 bits) and correct (1 bit) error in data 💅

🧚 SYNOPSIS 🧚

int omap_compare_ecc (u8 *ecc_data1 , u8 *page_data );

🎀 ARGUMENTS 🎀

• ecc_data1 — ecc code from nand spare area
• page_data — page data

🧠 DESCRIPTION 🧠

okay so this function compares two ECC's and indicates if there is an error 👀. If the error can be corrected it will be corrected to the buffer 🫶. If there is no error, 0 is returned. If there is an error but it was corrected, 1 is returned. Otherwise, -1 is returned. periodt.
