Hello,
I am writing an article about FreeBSD's startup
and kernel init
(it is at http://oasis.uptsoft.com/~devnull/dh/boot.html
for whom it may be interesting)
I am stucked at two lines in locore.s (IA 32 arch)
/usr/src/sys/i386/i386/locore.s:
pushl $begin /* jump to high virtualized address */
ret
/* now running relocated at KERNBASE where the system is linked to run */
begin:
/* set up bootstrap stack */
My question is:
why this is done. My understanding was that the loader
loaded the kernel at high virtual address already,
so there's no need to jump.
Thanks,
-sergey
