omap_write_page_bch(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… omap_write_page_bch(9) β€” like, the whole kernel API manual, bestie

okay so real talk, this page is from the Kernel API Manual and honestly it's giving "niche but iconic" β€” we're talking about omap_write_page_bch, a function that writes an entire page with BCH ecc. no cap, it does exactly what it says on the tin πŸŽ€


✨ NAME ✨

omap_write_page_bch β€” the BCH ecc based write page function, and yes it handles the entire page bestie, not just a lil slice πŸ“


🌸 SYNOPSIS 🌸

int omap_write_page_bch (struct nand_chip *chip , const uint8_t *buf ,
int oob_required , int page );

look at that signature. she's gorgeous. she takes four things and returns an int, periodt πŸ’…


πŸ¦‹ ARGUMENTS πŸ¦‹

  • chip β€” nand chip info structure. like, the whole info situation for the chip. she needs her context, okay? πŸ‘‘
  • buf β€” data buffer. this is where the actual data lives, the main character of the operation ✨
  • oob_required β€” must write chip->oob_poi to OOB. so if this flag's doing its thing, you gotta push chip->oob_poi over to the OOB area. that's the rule, fr fr 🫢
  • page β€” page. that's it. that's the argument. it's the page πŸ’€ (iconic minimalism honestly)

🌈 DESCRIPTION 🌈

so this is a custom write page method β€” and the way that it evolved specifically to support multi sector writing in one shot?? obsessed. one shot, many sectors, no extra trips. that's the vibe 😭πŸ”₯

tl;dr: it's a bespoke write-page path, built up over time so it can write multiple sectors in a single go. chef's kiss. 🧚
