Convert kernel over to bsdmake

PROG= kernel
Split of architecture-dependent and -independent functions for i386, 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

SMP - Cpu local variables - most global variables carry information which is specific to the local CPU and each CPU must have its own copy - cpu local variable must be declared in cpulocal.h between DECLARE_CPULOCAL_START and DECLARE_CPULOCAL_END markers using DECLARE_CPULOCAL macro - to access the cpu local data the provided macros must be used get_cpu_var(cpu, name) get_cpu_var_ptr(cpu, name) get_cpulocal_var(name) get_cpulocal_var_ptr(name) - using this macros makes future changes in the implementation possible - switching to ELF will make the declaration of cpu local data much simpler, e.g. CPULOCAL int blah; anywhere in the kernel source code

SMP - We boot APs - kernel detects CPUs by searching ACPI tables for local apic nodes - each CPU has its own TSS that points to its own stack. All cpus boot on the same boot stack (in sequence) but switch to its private stack as soon as they can. - final booting code in main() placed in bsp_finish_booting() which is executed only after the BSP switches to its final stack - apic functions to send startup interrupts - assembler functions to handle CPU features not needed for single cpu mode like memory barries, HT detection etc. - new files kernel/smp.[ch], kernel/arch/i386/arch_smp.c and kernel/arch/i386/include/arch_smp.h - 16-bit trampoline code for the APs. It is executed by each AP after receiving startup IPIs it brings up the CPUs to 32bit mode and let them spin in an infinite loop so they don't do any damage. - implementation of kernel spinlock - CONFIG_SMP and CONFIG_MAX_CPUS set by the build system

APIC mode uses IO APICs - kernel turns on IO APICs if no_apic is _not_ set or is equal 0 - pci driver must use the acpi driver to setup IRQ routing otherwise the system cannot work correctly except systems like KVM that use only legacy (E)ISA IRQs 0-15
