zynq_qspi_exec_mem_op(9)

📦 version 7.3.1, in nixpkgs unstable

💅 zynq_qspi_exec_mem_op(9) — like, the Kernel API Manual edition, bestie

okay so this is a page straight out of the Kernel API Manual, and it's all about one lil' function that kicks off a QSPI transfer. yes, that one. let's get into it 🎀

✨ NAME ✨

zynq_qspi_exec_mem_op — the way it initiates the QSPI transfer. that's the whole vibe. it starts the thing. periodt. 💫

🌸 SYNOPSIS 🌸

int zynq_qspi_exec_mem_op (struct spi_mem *mem , const struct spi_mem_op
*op );

that's the function signature, copied exactly, no notes. she returns an int, she takes two pointers, she's booked and busy. 💅

🫶 ARGUMENTS 🫶

  • mem — the SPI memory. like, the actual memory object we're working with, bestie. that's her.
  • op — the memory operation to execute. this is the what are we even doing here of it all. the whole plan, in one struct.

🦋 DESCRIPTION 🦋

so basically: it executes a memory operation. that's it, that's the job. 🔥

lowkey the important bit is the order of things, okay? this function first selects the chip and starts the memory operation. chip select first, then the operation. don't flip it, don't mess with it, it's giving very much "trust the process." 👑

💖 RETURN 💖

  • 0 — slay! it worked, success, we love to see it. ✨
  • a negative error code — literally anything else, and that means something went wrong. not the vibe, but at least you know. 😭

🎀 SEE ALSO 🎀

iykyk — go read them, they're all part of the same story. 🌈

fr fr keep the details: this page lives under ./drivers/spi, it's stamped October 2026, and it's part of the Kernel API Manual. 💜

okay that's the whole page, bestie — go forth and execute those memory ops responsibly. mwah! 🍓🧚‍♀️
