The Linux kernel parses these tables and creates platform devices, PCI devices, or ACPI-defined devices accordingly. Each device in ACPI has a unique – a string like PNP0501 (legacy serial port) or INT33BD (Intel I2C controller). Each device in ACPI has a unique –
ACPI is the standard for device discovery, power management, and configuration in x86 systems (and increasingly ARM servers). When a PC boots, the BIOS/UEFI provides the OS with ACPI tables (DSDT, SSDT, etc.). These tables contain AML (ACPI Machine Language) bytecode that describes every device on the motherboard: PCIe slots, UARTs, I2C controllers, GPIOs, and more. These tables contain AML (ACPI Machine Language) bytecode
