💅 device_resume_early(9) — Kernel API Manual 🎀

okay so bestie, welcome to device_resume_early(9) — literally the "wake up babe, the early resume callback is calling" page from the Kernel API Manual. grab a snack, this one's short and sweet. ✨

✨ NAME ✨

device_resume_early — Execute an "early resume" callback for given device.

🦋 SYNOPSIS 🦋

void device_resume_early (struct device *dev , pm_message_t state , bool async );

🌸 ARGUMENTS 🌸

• dev — Device to handle. the whole point, honestly. 🫶
• state — PM transition of the system being carried out. big "what kind of nap were we taking" energy.
• async — If true, the device is being resumed asynchronously. no cap, that's the whole flag.

💜 DESCRIPTION 💜

Runtime PM is disabled for dev while this function is being executed. that's it, that's the tea ☕ — literally the spotlight moment for dev and nobody else gets to touch the runtime PM knob. periodt.
