Implementations

impl Vga

pub fn set_memory_start(&mut self, video_memory_start: usize)

Set the start of video memory

The default is 0xA0000 for identity map to physical memory

Example

use vga;

vga::vga::VGA.lock().set_memory_start(0xa0000);

pub fn set_video_mode(&mut self, video_mode: VideoMode)

Sets the vga graphics card to the given VideoMode.

pub fn get_frame_buffer(&mut self) -> FrameBuffer

Gets the FrameBuffer address as specified by the Miscellaneous Output Register.

pub fn get_most_recent_video_mode(&self) -> Option<VideoMode>

Returns the most recent video mode, or None if no video mode has been set yet.

pub fn get_emulation_mode(&mut self) -> EmulationMode

Returns the current EmulationMode as determined by the miscellaneous output register.

pub fn load_font(&mut self, vga_font: &VgaFont)

Loads a vga text mode font as specified by vga_font.
