💖 device_set_wakeup_capable(9) 💖

okay so we’re in the Kernel API Manual today, bestie, and the main character is device_set_wakeup_capable(9). It’s giving “toggle the wakeup vibe” and we’re gonna get into it. 💅

🎀 NAME 🎀

device_set_wakeup_capable — Set/reset device wakeup capability flag.

✨ SYNOPSIS ✨

void device_set_wakeup_capable (struct device *dev , bool capable );

🫶 ARGUMENTS 🫶

• dev — Device to handle.
• capable — Whether or not dev is capable of waking up the system from sleep.

💅 DESCRIPTION 💅

If capable is set, set dev’s power.can_wakeup flag and add its wakeup-related attributes to sysfs. Otherwise, unset dev’s power.can_wakeup flag and remove its wakeup-related attributes from sysfs.

⚠️ This function may sleep, and it can’t be called from any context where sleeping is not allowed. Periodt. 😭
