I can walk the page table conceptually without a problem. My problem is that I've moved the payload in my binary and modified the page tables to use 4KB instead of 2MB pages. This works in a special case, but no the general case and I'm trying to understand why. I suspect I've ...

页表(page table) 在共享的物理内存上如何创建出不同程序的地址空间呢? 最常见的方法,同时也是非常灵活的一种方法就是使用页表(Page Tables)。页表就是一个数组,他的元素就是一个个页表条目(PTE),使用 页表可以实现虚拟内存地址到物理内存地址的翻译,页表存储在内存中,由 OS 负责维护,内存管理单元(Memory Manageme...

1. 减少页表(Page Table)大小。每一个Huge Page,对应的是连续的2MB物理内存,这样12GB的物理内存只需要48KB的Page Table,与原来的24MB相比减少很多。 2. Huge Page内存只能锁定在物理内存中,不能被交换到交换区。这样避免了交换引起的性能影响。 3. 由于页表数量的减少,使得CPU中的TLB(可理解为CPU对页表的CACHE...
