acpi_subsys_runtime_resume(9)

💅 acpi_subsys_runtime_resume(9) — from the Kernel API Manual, bestie

okay so bestie, listen up: this is acpi_subsys_runtime_resume, a little function from the Kernel API Manual, and honestly it's giving "wake up babe, we're going to full power" ✨

---

🌸 NAME

acpi_subsys_runtime_resume — resume a device using ACPI 💖

---

🎀 SYNOPSIS

int acpi_subsys_runtime_resume (struct device *dev );

---

🦋 ARGUMENTS

• dev — the device you wanna resume. That's it. That's the whole argument list. (Capital R "Resume" in the original, we respect the capitalization 💅)

---

✨ DESCRIPTION

So here's the vibe 🌈: this function uses ACPI to put the given device into the full-power state, and then it carries out the generic runtime resume procedure for it. Two jobs, one function, main character energy fr fr 👑

Like — it's not just poking the device awake, it's doing the ACPI part and the generic runtime resume part, together, slay 🫶
