💅 zynqmp_qspi_irq — the kernel API manual, bestie edition 🎀

okay so this is zynqmp_qspi_irq(9) from the Kernel API Manual, and honestly? it's a little icon of a function. let's get into it ✨

🌸 NAME 🌸

zynqmp_qspi_irq — the interrupt service routine of the QSPI controller. that's it, that's the whole job, and it does it slayfully 💖

🦋 SYNOPSIS 🦋

irqreturn_t zynqmp_qspi_irq (int irq , void *dev_id );

like yes, that's the signature, copy it exactly, don't freestyle it 🙈

✨ ARGUMENTS ✨

  • irq — the IRQ number. it's giving "which interrupt are we even talking about" energy 🔥
  • dev_id — a pointer to the xqspi structure. that's our main character pointer, fr fr 👑

🌈 DESCRIPTION 🌈

okay so listen. this function handles TX empty only. that's the vibe check: TX empty, nothing else, don't come to it with other interrupts 💅

on a TX empty interrupt, this function:

  1. reads the received data from the RX FIFO
  2. fills the TX FIFO if there is any data remaining to be transferred

that's the whole flow and honestly it ate 🫶

⭐ RETURN ⭐

  • IRQ_HANDLED when the interrupt is handled 💚
  • IRQ_NONE otherwise 💀

like, pick one, it's not complicated bestie
