This specific identifier acts as an alternative "Hardware ID" (_HID). It allows standard operating systems to identify, enumerate, and load drivers for embedded hardware components that lack a traditionally registered, industry-standard vendor plug-and-play ID.
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
— The compatible property does not have to be in the device's own _DSD . If any ancestor provides a compatible property, the child inherits it.
It is used when a device is connected via a low-level serial bus (like I2C or SPI) rather than a native bus like PCI. acpi prp0001 0
ACPI PRP0001 0 (commonly surfaced in kernel logs as messages referencing “prp0001” or similar identifiers) denotes a platform resource-provisioning ACPI object associated with device provisioning and power/resource management on modern x86 and ARM platforms. This editorial explains what PRP0001 is, its origin and purpose within ACPI, why it appears in logs, practical implications for system integrators and users, diagnostic approaches, remediation strategies, and forward-looking considerations for firmware and OS maintainers.
The kernel’s ACPI subsystem contains a defined symbol for this ID, ACPI_DT_NAMESPACE_HID , which maps directly to the "PRP0001" string.
If you are dealing with ACPI\PRP0001 entries slowing down or cluttering your Device Manager, use these step-by-step methods to clear them. Method 1: The Steam Deck Solution This specific identifier acts as an alternative "Hardware
If your device is a Valve Steam Deck running Windows, these missing entries represent the and peripheral sub-buses. Visit the official Steam Deck Windows Resources page.

: Used primarily by x86 systems (Intel and AMD desktops, laptops, and servers). It uses structured tables in the BIOS to tell the operating system what components exist and how to power them. ACPI PRP0001 0 (commonly surfaced in kernel logs
In the world of ACPI (Advanced Configuration and Power Interface), PRP0001 is a special "placeholder" ID used by Linux to link hardware devices to their drivers using data instead of traditional ACPI tables. When you see this ID in Windows, it usually means:
At its core, is a special "plug and play" ID used within ACPI (Advanced Configuration and Power Interface) tables. Its specific purpose is to allow software to use Device Tree (DT) bindings inside an ACPI-based system. ACPI is the standard on most x86 (Intel/AMD) systems.
Contains a UUID and a package containing a "compatible" string.
