Struct stivale_boot::v2::StivaleAnyVideoTag

source · [−]

#[repr(C, packed)]
pub struct StivaleAnyVideoTag { /* private fields */ }

Expand description

This tag tells the bootloader that the kernel has no requirement for a framebuffer to be initialised. Omitting both the any video header tag and the framebuffer header tag means “force CGA text mode” (where available), and the bootloader will refuse to boot the kernel if it fails to fulfill that request.

Implementations

impl StivaleAnyVideoTag

pub const fn new() -> Self

pub const fn next(self, next: *const ()) -> Self

pub const fn preference(self, value: u64) -> Self

0: prefer linear framebuffer

1: prefer no linear framebuffer (CGA text mode if available)

All other values undefined.
