bestie, welcome to the Kernel API Manual — this is the page for dev_pm_set_..._irq_reverse(9), and it is lowkey niche but iconic.

🌸 NAME 🌸

dev_pm_set_dedicated_wake_irq_reverse — Request a dedicated wake-up interrupt with reverse enable ordering

---

✨ SYNOPSIS ✨

int dev_pm_set_dedicated_wake_irq_reverse (struct device *dev , int irq
);

---

🎀 ARGUMENTS 🎀

• dev — Device entry
• irq — Device wake-up interrupt

---

💖 DESCRIPTION 💖

okay so real talk: unless your hardware has separate wake-up interrupts in addition to the device IO interrupts, you don't need this. like, not to be dramatic, but this function is not for you in that case 💀

This sets up a threaded interrupt handler for a device that has a dedicated wake-up interrupt in addition to the device IO interrupt.

It sets the status of WAKE_IRQ_DEDICATED_REVERSE to tell rpm_suspend to enable the dedicated wake-up interrupt after running the runtime suspend callback for dev. periodt 💅
