stm32h7_spi_irq_thread(9)

💅 stm32h7_spi_irq_thread(9) — from the Kernel API Manual, bestie

okay so picture this: it's the Kernel API Manual, and today's main character is stm32h7_spi_irq_thread. yeah. she's the threaded half of the interrupt handler for the SPI controller, and she is booked and busy 🎀

---

✨ NAME ✨

stm32h7_spi_irq_thread — literally the thread of the interrupt handler for the SPI controller. that's her whole job description and she's owning it 🫶

---

🌸 SYNOPSIS 🌸

irqreturn_t stm32h7_spi_irq_thread (int irq , void *dev_id );

look at her. signature so clean. so iconic. and yes she returns irqreturn_t, no she will not be elaborating 💅

---

🦋 ARGUMENTS 🦋

• irq — the interrupt line. that's the whole vibe. it's the line that goes "hey. hey bestie. something happened." 🔥
• dev_id — the SPI controller interface. this is the actual SPI controller we're out here handling interrupts for, no cap ✨
