3. In- depth analysis of the reverse mapping mechanism of the Linux kernel
We all know that the cpu accesses virtual addresses after the operating system turns on mmu. When the cpu accesses a virtual address, the virtual address needs to be converted into a physical address through mmu, which is called forward mapping. Related to this article is reverse mapping, which mainly uses the physical page to find the page table entries corresponding to all vma sharing this page. This is the problem discussed in this article. 【Read the original text】
