Introduction

This crate provides the struct, enums about the proka bootloader, including the boot information, memory map, and so on.

Example

Here’s an example to use this crate:

#![no_std]
#![no_main]
#![feature(custom_test_frameworks)]
#![test_runner(self::test_runner)]
#![reexport_test_harness_main = "test_main"]
 
use proka_bootloader::BootInfo;
use core::panic::PanicInfo;
 
// Panic handler
#[panic_handler]
pub fn panic(_: &PanicInfo) -> ! {
    loop {}
}
 
#[unsafe(no_mangle)]
#[unsafe(link_section = ".text")]
pub extern "C" fn kernel_main() -> ! {
    let info = proka_bootloader::get_bootinfo();
    let framebuffer = info.framebuffer();

    // Draw a straight line...
    unsafe {
        let ptr = framebuffer.address() as *mut u8;     
        for i in 0..500 {   
            let offset = framebuffer.pitch() * i + i * framebuffer.bpp();
            ptr.add(offset as usize).cast::<u32>().write(0x00FFFFFF);
        }
    }
    loop {}
}
 
// Test runner
#[cfg(test)]
fn test_runner(tests: &[&'static dyn Fn()]) {
    for test in tests {
        test();
    }
}

Modules

header

The definition of proka-kernel header.

memory

The generic memory module, which provides memory info to kernel, so that kernel can know the memory structure easily.

output

The output module, which provides framebuffer info and its utilities.

Structs

BootInfo

This struct is the boot information struct, which provides the basic information, memory map, and so on.

Enums

BootMode

This is the boot mode, only support 2 modes, which are legacy(BIOS) and UEFI.

Functions

get_bootinfo^⚠

Get the bootinfo.
