Acpi Prp0001 0

In Linux, PRP0001 allows hardware to be described using standard ACPI tables while still utilizing the of_match_table (Open Firmware) typically used in Device Tree environments. This means a single Linux driver can support both ARM-based (Device Tree) and x86-based (ACPI) systems without needing a unique ACPI ID for every small component. Troubleshooting "Unknown Device" (Windows)

Suppose a device has both a PRP0001 entry (to load a DT driver) and a legacy PNPXXXX HID (for an older ACPI driver). The kernel may prefer the DT driver via PRP0001. Disabling PRP0001 forces the kernel to fall back to the native ACPI driver – useful for performance comparison or bug workarounds. acpi prp0001 0
