acpi_pm_pre_suspend(9)

💖 acpi_pm_pre_suspend(9) — the kernel API manual, but make it cute ✨

okay so bestie, this is a function from the acpi_pm_pre_suspend section of the kernel API manual and it's literally the pre-suspend errand-runner. it does three things and it does them slayfully, no cap:

• enables wakeup devices 🔔
• "freezes" the EC ❄️
• saves NVS 💾

that's the whole vibe. iconic, honestly.

✨ NAME ✨

acpi_pm_pre_suspend — Enable wakeup devices, "freeze" EC and save NVS. 🫶

like… it's giving "get everything tucked in before the nap" energy. the wakeup devices get enabled, the EC gets "frozen" (yes, in quotes, that's how the original says it, iykyk), and NVS gets saved. periodt. 💅
