|
||||||
|

|

|
* One way to work around this is to have the linker do the
|
||||||
|
* math instead of the assembler. This solves the very
|
||||||
|
* pratical problem of being able to write code that can
|
||||||
|
* be relocated.
|
||||||
|
*
|
||||||
|
* An lgdt call before we have memory enabled cannot be
|

|
* position independent, as we cannot execute a call
|

|
* instruction to get our current instruction pointer.

|
* relocatable.

|
*
|
||||||
|
* The criteria for relocation have been relaxed to their
|
||||||
|
* utmost, so that we can use the same code for both
|
||||||
|
* our initial entry point and startup of the second CPU.
|
||||||
|
* The code assumes when executing at _start16bit that:
|
||||||
|
* (((cs & 0xfff) == 0) and (ip == _start16bit & 0xffff))
|
||||||
|
* or
|
||||||
|
* ((cs == anything) and (ip == 0)).
|
||||||
|
*
|
||||||
|
* The restrictions in reset16.inc mean that _start16bit initially
|
||||||
|
* must be loaded at or above 0xffff0000 or below 0x100000.
|
||||||
|
*
|
||||||
|
* The linker scripts computes gdtptr16_offset by simply returning
|
||||||
|
* the low 16 bits. This means that the initial segment used
|
||||||
|
* when start is called must be 64K aligned. This should not
|
||||||
|
* restrict the address as the ip address can be anything.
|
||||||
|
*
|
||||||
|
* Also load an IDT with NULL limit to prevent the 16bit IDT being used
|
||||||
|
* in protected mode before c_start.S sets up a 32bit IDT when entering
|
||||||
|
* RAM stage. In practise: CPU will shutdown on any exception.
