ACPI PRP0001: A Comprehensive Overview
To stop duplicating code, Linux kernel developers created the PRP0001 hardware ID.
- Usually, ACPI uses IDs like
INT34C3(I2C HID device) orPNP0F03(PS/2 mouse). - But if a device doesn’t have a native ACPI driver, Linux can instead use a Device Tree node attached to this ACPI device, as long as the ACPI table provides a
compatiblestring in the_DSD(Device Specific Data) property.
She decided to poke 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.
In Linux, the ACPI PRP0001 device is supported by the acpi kernel module. The acpi module provides a framework for interacting with ACPI devices, including the PRP0001. Linux distributions often use the acpi module to manage power consumption and configuration of ACPI devices. acpi prp0001 0
Lin's heart hammered. "That's impossible. ACPI tables are static data. They can't execute logic."
Whether you are debugging driver failures, customizing firmware, or simply satisfying technical curiosity, understanding acpi prp0001 0 gives you a deeper appreciation of how Linux supports hybrid embedded systems. ACPI PRP0001: A Comprehensive Overview To stop duplicating
Method A: Using dmesg
Run dmesg | grep -i prp0001. You will often see output similar to this:
