spi_nor_spimem_bounce(9)

📦 version 7.3.1, in nixpkgs unstable

💅 spi_nor_spimem_bounce — from the Kernel API Manual (yes that one, the kernel one, bestie)

okay so real talk, this function is a vibe check for your data transfer ✨ It's asking the universe (and the SPI NOR layer) one very important question: do we need a bounce buffer for this transfer or not? That's it. That's the whole job. And she does it flawlessly, no cap 💖

✨ SYNOPSIS ✨

bool spi_nor_spimem_bounce (struct spi_nor *nor , struct spi_mem_op *op
);

like. look at her. two args, returns a bool, zero drama 🎀

🌸 ARGUMENTS 🌸

  • nor — pointer to struct spi_nor, aka the little guy we're working with 🫶
  • op — pointer to struct spi_mem_op, the template for the transfer. template!! she's a blueprint bestie 💅

🔥 DESCRIPTION 🔥

so here's the tea ☕ If we have to use the bounce buffer — like, if it turns out we genuinely need one — then the data field inside op gets updated. that's the whole behaviour. she checks, and if it's a bounce-buffer kind of situation, she edits op for you. iconic 💖

no extra steps, no side quests, just a tidy little field update when the vibes demand it ✨

🦋 RETURN 🦋

  • true — the bounce buffer is needed, bestie, we're bouncing 😭
  • false — nope, not needed, we're good, carry on 💜
