Attribute Macro main 

#[main]

Marks a function to be called on the primary core after the platform initialization.

The function signature must be fn(cpu_id: usize, arg: usize) -> !, where cpu_id is the logical CPU ID (0, 1, …, N-1, N is the number of CPU cores on the platform), and arg is passed from the bootloader (typically the device tree blob address).

Example

#[axplat::main]
fn primary_main(cpu_id: usize, arg: usize) -> ! {
    todo!() // Your code here
}
