This article dissects the ACPI PRP0001 HID , its role in enabling device-tree-compatible drivers on ACPI systems, and the unusual purpose of disabling this feature via the acpi prp0001 0 kernel command line. The ACPI hardware ID is a special "fallback"
It is primarily used in systems designed with both Linux/Coreboot and Windows compatibility in mind, where the BIOS provides a unified description of hardware. Common scenarios include: Chromebooks: Almost all modern Chromebooks use I can inhabit a connected webcam, a microphone, a speaker
