[0032] figure 1 Is the general flowchart of the present invention.
[0033] Step 1), allocate memory space to the page table Allocated PTEs of size N and another page table entry Special PTE;
[0034] Step 2), write address A for Allocated PTEs, and write address B for Special PTEs;
[0035] Step 3), sequentially read the content of Allocated PTEs with a size of N, so that all page table entries pointing to address A are stored in the page table buffer register;
[0036] Step 4), without changing the content of the page table buffer, change the content of the Allocated PTEs pointer to the address B pointed to by the Special PTE in turn;
[0037] Step 5), execute a privileged instruction RDMSR;
[0038] Step 6), set a counter, the initial value is N, set the pointer i, and make the pointer point to the starting address of the page table buffer register;
[0039] Step 7), if the pointer i has traversed all the page table entries in the page table buffer register, then execut...
