Normally, every piece of hardware has a specific, unique ID (like "PNP0A0A" for an ASUS component). However, is a generic ID that tells the operating system: "I don't have a unique ACPI ID, so please look at my software-defined properties to figure out who I am" . Where you will usually see it
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 acpi prp0001 0
By ensuring your ACPI tables have a valid compatible property and your drivers have a proper of_match_table , you can leverage the full power of PRP0001 to bring up devices on your x86 or ACPI-based ARM platform without waiting for official ACPI IDs. Normally, every piece of hardware has a specific,
Because this identifier is used across multiple platforms, the exact fix depends on the device you are using. Follow the relevant solution blueprint below. Method 1: The Steam Deck Resolution Faster Hardware Prototyping By ensuring your ACPI tables

Early patches for ACPI support sometimes incorrectly added a static acpi_device_id entry like "PRP0001", 0 to drivers. Adding PRP0001 to an ACPI match table is unnecessary and counterproductive because PRP0001 devices are specifically designed to be matched via the of_match_table . Doing so can create ambiguous matching paths and break the intended behavior.
