On some ARM64 distributions (e.g., Fedora, Ubuntu for Raspberry Pi), the kernel is compiled with both ACPI and Device Tree support. If the firmware provides both a DSDT and a DT blob, the kernel may attempt ACPI enumeration first, find PRP0001 entries, and then fail when no ACPI driver exists — because the real driver expects DT.
While the ACPI PRP0001 device is generally well-supported by Linux, issues can still arise. Common problems include: acpi prp0001 0
The ACPI (Advanced Configuration and Power Interface) PRP0001 is a specific type of device that has been gaining attention in recent years, particularly among Linux users and developers. In this article, we will delve into the world of ACPI PRP0001, exploring what it is, how it works, and its significance in modern computing. On some ARM64 distributions (e
The ACPI PRP0001 device works by interacting with the Linux kernel's power management subsystem. When the device is detected, the kernel's power management code is notified, and it begins to manage the device's power-related functions. When the device is detected, the kernel's power
