-raw_switch:
-
- Provides the code to switch between real and protected mode.
- Switches between the environments "completely":
- e.g. when switching to protected mode,
- all the normal protected-mode state for that environment is set up.
-
-raw_pmode:
-
- i16_raw_enter_pmode()
- Enters protoected mode from real mode.
- Does not initialize IDT or TSS or anything else;
- just gets the system into protected mode
- with a simple temporary GDT.
- Returns with interrupts turned off
- (and they'd better stay off until there's a valid pmode IDT!)
-
- i16_raw_leave_pmode()
- Assumes paging is turned off.
- Returns with interrupts turned off;
- they can probably be turned back on at any time.
-
- Depends on:
- i16_die()
- A20 enable/disable code (e.g. raw_a20).
- gdt.h: KERNEL_16_CS, KERNEL_16_DS
-
-
-
-vm_param.h:
-
- Must export kvtolin(), lintokv()
