Function init

bootloader/kernel/src/memory.rs:12–15

Initialize a new OffsetPageTable. This function is unsafe because the caller must guarantee that the complete physical memory is mapped to virtual memory at the passed `physical_memory_offset`. Also, this function must be only called once to avoid aliasing `&mut` references (which is undefined behavior).

(physical_memory_offset: VirtAddr)

/// `physical_memory_offset`. Also, this function must be only called once
/// to avoid aliasing `&mut` references (which is undefined behavior).
pub unsafe fn init(physical_memory_offset: VirtAddr) -> OffsetPageTable<'static> {
    let level_4_table = active_level_4_table(physical_memory_offset);
    OffsetPageTable::new(level_4_table, physical_memory_offset)
}

/// Returns a mutable reference to the active level 4 table.
