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