Struct KState 

pub struct KState {
    pub cpu: Cpu,
    pub kprint: KPrint,
    pub mm: Mm,
    pub sched: Sched,
    pub vfs: Vfs,
}

The central kernel state aggregate; one field per OS subsystem domain.

Fields

cpu: Cpu

kprint: KPrint

mm: Mm

sched: Sched

vfs: Vfs

Implementations

impl KState

pub fn init(&self)

Calls the init method of all subsystems which have one

This method should be the very first call the kernel makes, as without it, a lot of KSTATE will be in an incorrect state for the boot process

Use this to initialize any non-zero default values; those aren’t initialized in the const fn new, as that would increase the binary size by the size of the entire KSTATE struct, which we don’t want
