Struct PteInfo 

Source 
pub struct PteInfo<P: PageTableEntry> {
    pub level: usize,
    pub vaddr: VirtAddr,
    pub is_final_mapping: bool,
    pub pte: P,
}
Expand description

页表项信息，包含原PTE对象

Fields§

§level: usize

页表级别（1=叶子页表，数字越大级别越高）

§vaddr: VirtAddr

此页表项对应的虚拟地址

§is_final_mapping: bool

此页表项是否为最终映射（叶子级别或大页）

  • true: 有效的叶子级别映射或大页映射
  • false: 无效项或中间级别的页表指针
§pte: P

原页表项对象
