stm32fx_spi_irq_thread(9)

✨ stm32fx_spi_irq_thread(9) ✨

okay so bestie, welcome to the Kernel API Manual 🎀 — this one's a lil threaded-interrupt-handler moment and it's lowkey iconic. it's giving "the bottom half that does the actual work" energy 💅

---

🌸 NAME 🌸

stm32fx_spi_irq_thread — the thread of the interrupt handler for the SPI controller 🦋

like, the handler's handler. the chill sidekick that runs in thread context. periodt.

---

✨ SYNOPSIS ✨

irqreturn_t stm32fx_spi_irq_thread (int irq , void *dev_id );

that's the whole vibe check: you hand it an int and a void pointer, and it gives you back an irqreturn_t. no cap 🫶

---

💖 ARGUMENTS 💖

• irq — the interrupt line 💫 like, which IRQ are we talking about, bestie
• dev_id — the SPI controller interface 🌈 the actual device thing you passed in when you registered
