💅 zynqmp_qspi_exec_op(9)

okay so this is a page from the Kernel API Manual — yes, the Kernel API Manual, we're doing real kernel shit today bestie, stay with me 🫶

✨ NAME ✨

zynqmp_qspi_exec_op — the function that, like, actually kicks off the QSPI transfer. main character energy fr 💫

🎀 SYNOPSIS 🎀

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

like, that's it. that's the whole signature. two args, one int back. iconic minimalism 🔥

🌸 ARGUMENTS 🌸

  • mem — the SPI memory 🧚 that's your SPI memory object, the thing you're talking to
  • op — the memory operation to execute ✨ this is the actual thing you want done, packaged up and ready to go

💖 DESCRIPTION 💖

Executes a memory operation. simple as that, no cap.

the way this works: this function first selects the chip, and then starts the memory operation. so chip-select happens, then the op runs. in that order. that's the whole vibe check 💅

⭐ RETURN ⭐

0 in case of success, a negative error code otherwise. so like — zero? slay. negative? 😭 something went wrong, go check it.
