| | Summary | |---|---| | What it is | A special ACPI Hardware ID ( PRP0001 ) that tells Linux to match a device using Device Tree compatible strings instead of ACPI IDs. | | Primary use case | Enabling Linux drivers written for Device Tree systems to operate on ACPI platforms without any driver modifications. | | Syntax requirement | Device object must contain Name (_HID, "PRP0001") and a compatible property inside a _DSD package. | | Optional fallback | Use _CID("PRP0001") alongside an official _HID for transitional support. | | Bus support | Works with platform devices, I²C, and SPI. Does not work with PCI or USB. | | Windows compatibility | Not directly supported. Windows treats PRP0001 devices as unknown hardware unless a vendor provides a specific driver INF file. | | Kernel requirements | Linux kernel 4.1+ for basic support; 5.4+ for full I²C PRP0001 enumeration; 6.14+ for improved match data handling. | | Most common trouble | PRP0001 devices appear in Windows Device Manager without drivers; Linux i2c-PRP0001:XX generic names; missing match data for Rust drivers. |

The table below summarizes the three main use cases for PRP0001: acpi prp0001 0

Hardware manufacturers only have to write a single Linux driver using the modern device_property_read_... API. That single driver will work perfectly on a Raspberry Pi (Device Tree) and an Intel Xeon Server (ACPI). 2. Faster Hardware Prototyping

Paper:

is a fixed _HID (Hardware ID) value that informs the Linux kernel: "Do not try to match me using conventional ACPI IDs. Instead, read my compatible property from the _DSD (Device-Specific Data) and match me using the driver's Device Tree match table." You will see messages similar to: Linux will

Manufacturers can support new hardware on x86 platforms without registering a formal ACPI ID.

This identifier is not a hardware malfunction. Instead, it represents a bridge between two different engineering standards used to manage system hardware: and Device Tree (Open Firmware) . What is the PRP0001 Device ID?

The identifier is a critical bridge between two different hardware description worlds: the Advanced Configuration and Power Interface (ACPI) typically found on Windows-based PCs and the Device Tree (DT) system common in Linux and embedded systems. | | Syntax requirement | Device object must

To stop duplicating code, Linux kernel developers created the PRP0001 hardware ID.

The special Hardware ID (HID) PRP0001 (often represented as ACPI\PRP0001\0 ) serves as a crucial bridge, allowing ACPI-enumerated systems to use device drivers that were originally designed for Device Tree, particularly for I2C and SPI devices. What is acpi prp0001 0 ?

Some vendor firmwares ship broken _DSD bundles for PRP0001 devices – malformed UUIDs, missing compatible , or referencing non-existent interrupts. This can cause:

: Windows does not recognize the device because it lacks the specific driver provided by the manufacturer (e.g., Valve for Steam Deck or Intel for specific chipsets).
