✨ pm_runtime_resume_and_get(9) ✨

okay bestie, welcome to the Kernel API Manual 💖 you're literally about to learn pm_runtime_resume_and_get, and honestly? she's that girl. let's get into it 🫶

🌸 NAME 🌸

pm_runtime_resume_and_get — bump up the usage counter of a device and resume it. that's it, that's the whole vibe. counter goes up, device wakes up, main character energy 🔥

✨ SYNOPSIS ✨

int pm_runtime_resume_and_get (struct device *dev );

like, no cap, that's the whole signature. int in, int out, struct device pointer goes in the middle 💅

🎀 ARGUMENTS 🎀

  • dev — the target device. your lil guy. the one you're doing all this for 🦋

💜 DESCRIPTION 💜

so here's the tea, bestie 🍓: this function resumes dev synchronously, and only if that resume actually goes through does it increment the device's runtime PM usage counter. it's giving "wake up bestie, then lock in."

the return value is lowkey simple:

  • returns 0 if the runtime PM usage counter of dev has been incremented ✅
  • returns a negative error code otherwise 😭 (translation: it did not pan out, don't celebrate yet)

periodt. that's the contract 💀 no hidden drama, no extra steps, just "resume, then bump the counter, or give me a negative number."
