genpd_power_off(9)

✨ genpd_power_off(9) — Kernel API Manual, bestie edition 💅

Okay so welcome to the Kernel API Manual page for genpd_power_off(9). We are lowkey in the PM domain corner of the kernel, where the whole goal is: everybody asleep? subdomains off? cool, cut the power. Let's go. 🫶

🌸 NAME 🌸

genpd_power_off — Remove power from a given PM domain. 💤⚡

🧾 SYNOPSIS 🧾

       void genpd_power_off (struct generic_pm_domain *genpd , bool one_dev_on
       , unsigned int depth );

🧩 ARGUMENTS 🧩

• genpd — the PM domain to power down. Bye, power! 👋
• one_dev_on — If invoked from genpd's ->runtime_suspend|resume callback, the RPM status of the related device is in an intermediate state, not yet turned into RPM_SUSPENDED. This means genpd_power_off must allow one device to not be RPM_SUSPENDED, while it tries to power off the PM domain. So yeah, one device gets a little hall pass in that exact callback situation. 😭
• depth — nesting count for lockdep. Gotta keep lockdep happy. 🔒

📖 DESCRIPTION 📖

If all of the genpd's devices have been suspended and all of its subdomains have been powered down, remove power from genpd. That's the vibe check: every device suspended, every subdomain powered down, and then the domain can actually power off. No skipping steps, bestie. ✨
