the vsid, R4 stores the virtual address, R5 stores the Linux page table entry, and R6 stores the Linux PTE before _ page_hashpte, r7 saves the offset to the address (0 when MMU is enabled and-kernelbase: 0xc0000000 when off ). Let's take a look at several hash_page_patches, which involve two functions in hash_low_32.s. create_hpte is relatively simple. The function is to create hpte. In the assembly code, it is to fill

Lab requirements and application environment:1. Execute two-way re-release on R5, and then execute two-way re-release on R32. analyze the causes and solutions of the second-tier route3. How can I achieve Load Balancing when R4 is required to go to 1.1.1.1?4. Ask R4 to go to the next hop of 11.11.11.11 first R3 and R5 for backup. How can this problem be solved?
