===== ACPI vs ASPM =====
ASPM (Active State Power Management) is a specific power-saving feature for PCI Express (PCIe) links, allowing individual devices to enter low-power states to save energy. In contrast, ACPI (Advanced Configuration and Power Interface) is a comprehensive, open standard that provides a framework for the operating system to manage the power and configuration of all hardware components, including ASPM. ACPI is the overarching standard that often incorporates and directs the use of ASPM, coordinating device and system-wide power states
