omap_calcula...cc_bch_multi(9)
π NAME π
omap_calculate_ecc_bch_multi β bestie, this one generates ECC for multiple sectors at once β¨
(also hi, you're in the Kernel API Manual, welcome to the group chat π«Ά)
πΈ SYNOPSIS πΈ
int omap_calculate_ecc_bch_multi (struct mtd_info *mtd , const u_char
*dat , u_char *ecc_calc );
π ARGUMENTS π
mtdβ the MTD device structure, aka the whole personality of the flash device you're working with πdatβ pointer to the data that the ECC is being computed on. yes, this data. the main character data π₯ecc_calcβ buffer where the calculated ECC bytes get stored. it's giving "here's where the math lives" π
π¦ DESCRIPTION π¦
okay so here's the vibe: this function supports calculating BCH4/8/16 ecc vectors for the entire page in one go π§β¨
one page, one call, all the ecc vectors. no cap. that's the whole thing and honestly? iconic π

ngl, that's a lot of friends. go read them too, iykyk π
and that's the page!! mwah π this one lives in ./drivers/mtd/nand/raw and it's dated October 2026 β so like, future vibes only πβ periodt.
