ACPI\PRP0001\0

The hardware ID is a special "fallback" identifier used in modern firmware to bridge the gap between two different ways computers describe their hardware: ACPI (common in Windows/PCs) and Device Tree (common in Linux/Embedded systems). Why is it "interesting"?

• Correct DSDT/SSDT AML to follow ACPI spec: proper resource descriptors, return values, and well-defined methods.
• Use standard, broadly supported HIDs when possible, and document vendor-specific HIDs.
• Coordinate with OS vendors so ACPI naming/drivers are aligned.

Step 3: Manually trigger a re-probe

In essence, when an ACPI device node has _HID set to PRP0001 , it tells the OS: "Don't look for a standard ACPI driver; instead, treat this device as if it were described by a Device Tree (DT) node. Look for a compatible string in my _DSD (Device Specific Data) properties." acpi prp0001 0

Now armed with this knowledge, go forth and tame your boot logs. ACPI\PRP0001\0 The hardware ID is a special "fallback"
