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 |

README for mdb version 2.6.0 Sept 9/96 Please note the following: 1) Has been tested with Minix 1.7.4 (32-bit version). A previous version was tested with Minix 1.7.x (16 bit version). Some optional parts of mdb have not been extensively tested. This is especially true on the code to trace system calls. See options in Makefile. 2) I know that the commands are somewhat cryptic; thus there are currently two types of 'help' for mdb a) the "?" gives a help page. b) typing "command ?" will give help on a specific command. 3) The sample comand file and log output. To test this, type something like the following "mdb -llog.new /usr/bin/sleep @sample" The output "log.new' should be similar to the distributed "log" file; but not necessarily exactly the same. 4) Man pages need some more work. 5) See top part of mdb.c for version history.
