vmw_irq_handler(9)

💖 vmw_irq_handler 💖

okay bestie, welcome to the Kernel API Manual — today’s main character is vmw_irq_handler(9), and she is literally the quick-response queen of IRQ processing. 🫶

✨ NAME ✨

vmw_irq_handler — irq handler. no cap, that’s the whole vibe. 💅

🌸 SYNOPSIS 🌸

irqreturn_t vmw_irq_handler (int irq , void *arg );

🎀 ARGUMENTS 🎀

• irq — the irq number. yes, that’s the number. iconic. 🔢
• arg — Closure argument. It’s a pointer to a struct drm_device cast to void *. 🦋

🔥 DESCRIPTION 🔥

This function implements the quick part of irq processing. She’s not doing the whole marathon — just the speedy lil’ moments. 🏃‍♀️💨

The function performs fast actions like clearing the device interrupt flags, and also reasonably quick actions like waking processes waiting for FIFO space. ✨

Other IRQ actions are deferred to the IRQ thread. that’s the division of labor, bestie. 💅
