acpi_dev_po...ren_with_adr(9)

okay bestie, welcome to the Kernel API Manual page for acpi_dev_po...ren_with_adr(9) — yes, the header is literally truncated like that, and we are rolling with it ✨. This is the group-chat explainer for acpi_dev_power_up_children_with_adr, no cap.

🌸 NAME 🌸

acpi_dev_power_up_children_with_adr — Power up childres with valid _ADR. (and yes, “childres” is the actual spelling on the page 💀 — we’re keeping it exactly, periodt.)

✨ SYNOPSIS ✨

void acpi_dev_power_up_children_with_adr (struct acpi_device *adev );

It’s void, so there’s no return value to obsess over. ✨

🎀 ARGUMENTS 🎀

• adev — the parent ACPI device object. That’s the main character here 👑.

💖 DESCRIPTION 💖

okay so picture this: this function changes the power states of the direct children of adev that are in D3cold and hold valid _ADR objects to D0. Why? So bus (e.g. PCI) enumeration code can access them. That’s the whole plot, and it ate 💅.
