Function stivale::load

pub unsafe fn load(address: usize) -> StivaleStructure

Load the stivale2 structure from an address

The structure pointer is passed in the EDI register

Safety

This function will cause undefined behavior when a non-stivale2 compliant bootloader boots the kernel

This can be avoided by creating a custom entry point that's not the ELF entry point, and setting that in the stivale2 header

Examples

let mut stivale_struct_ptr: u64 = 0;
unsafe { asm!("mov $2, %rdi" : "=r"(stivale_struct_ptr)) };
let stivale_struct = unsafe { stivale::load(stivale_struct_ptr as usize) };

fn kernel_main(stivale_struct_ptr: usize) {
    let stivale_struct = unsafe { stivale::load(stivale_struct_ptr) };
}
