+ While we make a 1:1 mapping (identity mapping) for all physical pages \r
+ we still need to use the MTRR's to ensure that the cachability attirbutes\r
+ for all memory regions is correct.\r
+\r
+ The basic idea is to use 2MB page table entries where ever possible. If\r
+ more granularity of cachability is required then 4K page tables are used.\r

- x64 Virtual Memory Management Services in the form of an IA-32 driver. \r
- Used to establish a 1:1 Virtual to Physical Mapping that is required to\r
- enter Long Mode (x64 64-bit mode).\r
-\r
- While we make a 1:1 mapping (identity mapping) for all physical pages \r
- we still need to use the MTRR's to ensure that the cachability attirbutes\r
- for all memory regions is correct.\r
-\r
- The basic idea is to use 2MB page table entries where ever possible. If\r
- more granularity of cachability is required then 4K page tables are used.\r
