Function get_bootinfo 

Source 
pub const unsafe fn get_bootinfo() -> &'static BootInfo
Expand description

Get the bootinfo.

The BootInfo is pre-copied & fixed at the dedicated constant physical address 0x10000 by UEFI boot stage, never modified nor released in kernel lifetime.

§Safety

Caller must ensure before invoking:

  1. Address 0x10000 is allocated & filled with valid initialized BootInfo;
  2. This range is reserved, never overwritten/freed by kernel/UEFI;
  3. No mutable aliasing exists for this memory region.

§Note

Once the kernel do remapping, i suggest that map that region as PRESENT, no WRITABLE.

§Returns

  • &'static BootInfo: immutable static reference to the pre-filled BootInfo
