- Enables the 64-bit paging mode on the CPU.\r
-\r
- Enables the 64-bit paging mode on the CPU. CR0, CR3, CR4, and the page tables\r
- must be properly initialized prior to calling this service. This function\r
- assumes the current execution mode is 32-bit protected mode with flat\r
- descriptors. This function is only available on IA-32. After the 64-bit\r
- paging mode is enabled, control is transferred to the function specified by\r
- EntryPoint using the new stack specified by NewStack and passing in the\r
- parameters specified by Context1 and Context2. Context1 and Context2 are\r
- optional and may be 0. The function EntryPoint must never return.\r
-\r
- If the current execution mode is not 32-bit protected mode with flat\r
- descriptors, then ASSERT().\r
- If EntryPoint is 0, then ASSERT().\r
- If NewStack is 0, then ASSERT().\r
-\r
- @param Cs The 16-bit selector to load in the CS before EntryPoint\r
- is called. The descriptor in the GDT that this selector\r
- references must be setup for long mode.\r
- @param EntryPoint The 64-bit virtual address of the function to call with\r
- the new stack after paging is enabled.\r
- @param Context1 The 64-bit virtual address of the context to pass into\r
- the EntryPoint function as the first parameter after\r
- paging is enabled.\r
- @param Context2 The 64-bit virtual address of the context to pass into\r
- the EntryPoint function as the second parameter after\r
- paging is enabled.\r
- @param NewStack The 64-bit virtual address of the new stack to use for\r
- the EntryPoint function after paging is enabled.\r
