Crate multiboot2

An experimental Multiboot 2 crate for ELF-64/32 kernels.

The GNU Multiboot specification aims provide to a standardised method of sharing commonly used information about the host machine at boot time.

Examples

use multiboot2::load;

// The Multiboot 2 specification dictates that the machine state after the
// bootloader finishes its job will be that the boot information struct pointer
// is stored in the `EBX` register.
let multiboot_info_ptr: u32;
unsafe { asm!("mov $2, %ebx" : "=r"(multiboot_info_ptr)) };
let boot_info = unsafe { load(multiboot_info_ptr) };

Structs

CommandLineTag	This Tag contains the command line string.
EFIImageHandle32	Contains pointer to boot loader image handle.
EFIImageHandle64	Contains pointer to boot loader image handle.
EFIMemoryDesc	EFI Boot Memory Map Descriptor
EFIMemoryMapTag	EFI memory map as per EFI specification.
EFISdt32	EFI system table in 32 bit mode
EFISdt64	EFI system table in 64 bit mode
ElfSection	A single generic ELF Section.
ElfSectionFlags	ELF Section bitflags.
ElfSectionIter	An iterator over some ELF sections.
ElfSectionsTag	This tag contains section header table from an ELF kernel.
FramebufferColor	A framebuffer color descriptor in the palette.
FramebufferField	An RGB color type field.
FramebufferTag	The VBE Framebuffer information Tag.
ImageLoadPhysAddr	If the image has relocatable header tag, this tag contains the image's base physical address.
MemoryArea	A memory area entry descriptor.
MemoryAreaIter	An iterator over all memory areas
MemoryMapTag	This Tag provides an initial host memory map.
ModuleIter	An iterator over all module tags.
ModuleTag	This tag indicates to the kernel what boot module was loaded along with the kernel image, and where it can be found.
RsdpV1Tag	This tag contains a copy of RSDP as defined per ACPI 1.0 specification.
RsdpV2Tag	This tag contains a copy of RSDP as defined per ACPI 2.0 or later specification.
VBECapabilities	The Capabilities field indicates the support of specific features in the graphics environment.
VBEControlInfo	VBE controller information.
VBEDirectColorAttributes	The DirectColorModeInfo field describes important characteristics of direct color modes.
VBEField	A VBE colour field.
VBEInfoTag	This tag contains VBE metadata, VBE controller information returned by the VBE Function 00h and VBE mode information returned by the VBE Function 01h.
VBEModeAttributes	A Mode attributes bitfield.
VBEModeInfo	Extended information about a specific VBE display mode from the mode list returned by VBEControlInfo (VBE Function 00h).
VBEWindowAttributes	The WindowAttributes describe the characteristics of the CPU windowing scheme such as whether the windows exist and are read/writeable, as follows:

Enums
