- a better name for architecture specific init function
- some of x86 init code must execute in protected mode
- prot_init() removed from this function and still called in cstart() Imho this
should be called from the architecture specific assembly not cstart. cstart
perform Minix monitor specific tasks and will be touched once another
bootloader is in use, e.g. booting via tftp, therefore we keep it as is for
now.
- this is a backport from the SMP code which requires this. Merging will be simpler
This is a backport form the SMP branch. Not required here, it only makes life
for SMP easier. And future merging too.
- filling the IDT is removed from prot_init()
- struct gate_table_s is a public type
- gate_table_pic is a global array as it is used by APIC code too
- idt_copy_vectors() is also global and used by idt_init() as well as
apic_idt_init()
- idt_init() is called right after prot_init() in system_init()
mainly in the kernel and headers. This split based on work by
Ingmar Alting <iaalting@cs.vu.nl> done for his Minix PowerPC architecture
port.
. kernel does not program the interrupt controller directly, do any
other architecture-dependent operations, or contain assembly any more,
but uses architecture-dependent functions in arch/$(ARCH)/.
. architecture-dependent constants and types defined in arch/$(ARCH)/include.
. <ibm/portio.h> moved to <minix/portio.h>, as they have become, for now,
architecture-independent functions.
. int86, sdevio, readbios, and iopenable are now i386-specific kernel calls
and live in arch/i386/do_* now.
. i386 arch now supports even less 86 code; e.g. mpx86.s and klib86.s have
gone, and 'machine.protected' is gone (and always taken to be 1 in i386).
If 86 support is to return, it should be a new architecture.
. prototypes for the architecture-dependent functions defined in
kernel/arch/$(ARCH)/*.c but used in kernel/ are in kernel/proto.h
. /etc/make.conf included in makefiles and shell scripts that need to
know the building architecture; it defines ARCH=<arch>, currently only
i386.
. some basic per-architecture build support outside of the kernel (lib)
. in clock.c, only dequeue a process if it was ready
. fixes for new include files
files deleted:
. mpx/klib.s - only for choosing between mpx/klib86 and -386
. klib86.s - only for 86
i386-specific files files moved (or arch-dependent stuff moved) to arch/i386/:
. mpx386.s (entry point)
. klib386.s
. sconst.h
. exception.c
. protect.c
. protect.h
. i8269.c
