Enum DeviceSource 

Source 
pub enum DeviceSource {
    Fdt(usize),
    Uefi,
    Acpi,
    None,
}
Expand description

Represents the source of device information during boot

Different boot protocols provide hardware information through various mechanisms. This enum captures the source and relevant parameters for device discovery.

Variants§

§

Fdt(usize)

Flattened Device Tree (FDT) source with relocated FDT address Used by RISC-V, ARM, and other architectures that support device trees

§

Uefi

Unified Extensible Firmware Interface (UEFI) source Modern firmware interface providing comprehensive hardware information

§

Acpi

Advanced Configuration and Power Interface (ACPI) source x86/x86_64 standard for hardware configuration and power management

§

None

No device information available Fallback when no hardware description is provided by firmware
