__pm_runtime_resume(9)

💅 __pm_runtime_resume — Kernel API Manual ✨

okay so bestie, welcome to the Kernel API Manual, and today's main character is __pm_runtime_resume(9) — literally the entry point for runtime resume operations. yes. THE entry point. 🎀

✨ SYNOPSIS ✨

int __pm_runtime_resume (struct device *dev , int rpmflags );

🫶 ARGUMENTS 🫶

• dev — the device you wanna resume. that's your girl. that's who we're waking up 💖
• rpmflags — the flag bits. lil switches that change how the whole thing goes down ✨

🔥 DESCRIPTION 🔥

okay so here's the tea ☕ — if the RPM_GET_PUT flag is set, you increment the device's usage count first. then you carry out a resume, and it can be synchronous or asynchronous — your call, based on those flags, iykyk 💅

and the important part, no cap: this routine may be called in atomic context if the RPM_ASYNC flag is set, or if pm_runtime_irq_safe has been called. that's the vibe check right there 👑

🫶 fr fr, remember that atomic-context bit — it's giving "read the flags before you do anything unhinged."
