The MSI memory location is a physical bus address, so it must be translated to virtual address space both on device and host.
由于大部分进程的虚拟地址空间大而散，页表入口只能定位在实际使用的那部分地址空间上。
Because the virtual address Spaces of most processes are both large and sparse, page table entries are only allocated for the portions of the address space that are actually used.
