Function Documentation

arch_halt()

void arch_halt

(

)

Shutdowns everything and performs a clean system halt.

arch_is_kernel_address()

bool arch_is_kernel_address

(

uintptr_t

addr

)

Determines whether an address points to kernel code.

Parameters

addr	an address

Returns

true if the address points to kernel code, false otherwise

It does not have to be perfect, we just have to believe it will be fine.

arch_poweroff()

void arch_poweroff

(

int

exit_code

)

Shutdowns everything and performs a clean system power off.
