Struct SimpleKernelState 

pub(crate) struct SimpleKernelState {
    pub(crate) serial: Once<Serial>,
    pub(crate) basic_fb: Once<BasicFramebuffer>,
    pub(crate) basic_fb_psf2_font: Once<Psf2Font>,
    pub(crate) pmm: Once<Pmm>,
    pub(crate) vmm: Once<Vmm>,
}

Early-boot singleton resources; written once in kmain, then read-only.

Kept separate from [KState] so the panic handler still has a reliable source of state if KState is unavailable.

Fields

serial: Once<Serial>

basic_fb: Once<BasicFramebuffer>

basic_fb_psf2_font: Once<Psf2Font>

pmm: Once<Pmm>

vmm: Once<Vmm>
