Added <minix/sys_config.h>. This file is intended to be included from other, user-includable config files. It only defines names that don't pollute the users namespace (start with _). <minix/config.h> still works like always; it includes sys_config.h now and defines the 'messy' names (such as CHIP) as the 'cleaner' names (such as _MINIX_CHIP). Changed some of the other include files to use sys_config.h and the 'cleaner' names. This solves some (past and future) compilation problems. 2005-08-29 15:52:08 +02:00			`#ifndef _MINIX_SYS_CONFIG_H`

added reenter check to lock_dequeue() to avoid unlocking of interrupts via cause_sig() during an exception. moved lock check configuration to <minix/sys_config.h> instead of kernel/config.h, because the 'relocking' field in kinfo depends on it. other prettification: common locking macro, whether lock timing is on or not. 2006-02-10 17:53:51 +01:00			`/* Kernel debug checks */`
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 2006-12-22 16:22:27 +01:00			`#define DEBUG_LOCK_CHECK 1 /* Interrupt Lock/unlock sanity checking. */`

reduce kernel buffer size. 2009-01-20 14:57:24 +01:00			`#define _KMESS_BUF_SIZE 10000`
Basic VM and other minor improvements. Not complete, probably not fully debugged or optimized. 2008-11-19 13:26:10 +01:00
exec() cleanup, generalization, improvement . make exec() callers (i.e. vfs and rs) determine the memory layout by explicitly reserving regions using mmap() calls on behalf of the exec()ing process, i.e. handling all of the exec logic, thereby eliminating all special exec() knowledge from VM. . the new procedure is: clear the exec()ing process first, then call third-party mmap()s to reserve memory, then copy the executable file section contents in, all using callbacks tailored to the caller's way of starting an executable . i.e. no more explicit EXEC_NEWMEM-style calls in PM or VM as with rigid 2-section arguments . this naturally allows generalizing exec() by simply loading all ELF sections . drop/merge of lots of duplicate exec() code into libexec . not copying the code sections to vfs and into the executable again is a measurable performance improvement (about 3.3% faster for 'make' in src/servers/) 2012-05-30 19:34:07 +02:00			`/* Default stack size (limit) */`
