How does ACPI SYS interact with the operating system and hardware components?
ACPI SYS interacts with the operating system and hardware components through a complex series of interfaces and protocols. The operating system provides a driver that communicates with the ACPI SYS firmware, which is stored in the system’s BIOS or UEFI. The firmware provides a set of tables and data structures that describe the system’s hardware components and their power management capabilities. The operating system uses this information to configure and manage the hardware components, ensuring that they operate within their designated power envelopes. This interaction enables the operating system to optimize power consumption, performance, and reliability, while also providing features such as sleep, hibernate, and wake-on-LAN.
The interaction between ACPI SYS and hardware components is critical to ensuring that the system operates efficiently and reliably. For example, when the operating system requests that the system enter a low-power sleep state, the ACPI SYS firmware coordinates with the hardware components to reduce power consumption and put the system into a dormant state. Similarly, when the system is awakened from a sleep state, the ACPI SYS firmware ensures that the hardware components are properly reinitialized and configured to resume normal operation. This complex interaction requires careful coordination and management, which is provided by the ACPI SYS firmware and the operating system driver.
