Move archtypes.h to include/ dir, since several servers require it. Move
fpu.h and stackframe.h to arch-specific header directory. Make source
files and makefiles aware of the new header locations.
this change
- makes panic() variadic, doing full printf() formatting -
no more NO_NUM, and no more separate printf() statements
needed to print extra info (or something in hex) before panicing
- unifies panic() - same panic() name and usage for everyone -
vm, kernel and rest have different names/syntax currently
in order to implement their own luxuries, but no longer
- throws out the 1st argument, to make source less noisy.
the panic() in syslib retrieves the server name from the kernel
so it should be clear enough who is panicing; e.g.
panic("sigaction failed: %d", errno);
looks like:
at_wini(73130): panic: sigaction failed: 0
syslib:panic.c: stacktrace: 0x74dc 0x2025 0x100a
- throws out report() - printf() is more convenient and powerful
- harmonizes/fixes the use of panic() - there were a few places
that used printf-style formatting (didn't work) and newlines
(messes up the formatting) in panic()
- throws out a few per-server panic() functions
- cleans up a tie-in of tty with panic()
merging printf() and panic() statements to be done incrementally.
- if "debug_fkeys" boot monitor variable is set to 0:
- pass Fn, Shift+Fn, Ctrl+Fn, Shift+Ctrl+Fn to applications
- don't start IS
- update termcap files with function key, color, end key support
IS:
- do not use p_getfrom_e for a process that is sending
- register with TTY only function keys that are used
- various header and formatting fixes
- proper shutdown code
TTY:
- restore proper Ctrl+F1 dump contents
isofs:
- don't even try to call sys_exit()
remembering the origin and cursor position as that feature didn't
really work properly anyway
- tty: map in video and font memory using a vm call, access it from C,
thereby eliminating pesky weird segment calls and assembly to access it,
and unbreaks loadfont (Roman Ignatov)
- bios_wini: fix bios_wini by allocating a <1MB buffers for it
- memory: preallocate ramdisk, makes it a bit faster (and doesn't
fail halfway if you allocate a huge one)
- floppy: use <1MB buffer
- ramdisk proto: because of the 2x1 page reservations, binaries
got a little fatter and didn't fit on the ramdisk any more.
increase it.
a little cleaner (escaped scancodes are less of a special case) and
lets us be completely flexible when assigning meaning to them.
Future: a tool and ioctl to load the escaped keymap.
to col selected from the keymap untill right-alt is pressed again.

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
include grant id in DEV_REVIVE messages.
. Removal of TTY_FLAGS field (and so O_NONBLOCK support).
. Fixed CANCEL behaviour and return code on blocking I/O,
previously handled by O_NONBLOCK
. Totally removed REVIVE replies, previously still possible on
blocking ioctls (REVIVE directly called) and ptys (missing TTY_REVIVE
check), removes deadlock bug with FS
. Removed obsolete *COMPAT options and associated code
initialization. One-time init is called from tty.
Side effect is that the one-time init is done after the sys_getmachine()
call, which makes set_leds() work, which makes numlock go off at booting.
Output during initialization should be suppressed. Unless an error occurs.
Note that main() can now be main(int argc, char **argv) and arguments can
be passed when bringing up the driver.
to provide an index (0 .. 31) that is passed in the HARD_INT message when an
interrupt occurs. The NOTIFY_ARG field contains a bitmap with all indexes for
which an interrupt occured.
TTY: select and revive with new notify and FS call back;
kernel: removed old notify code; removed ugly prepare_shutdown timer
kputc: don't send to FS if PRINTF_PROC fails
The TTY driver now only notifies the IS server about function key event,
but does not tell which keys are pressed. The IS servers queries the TTY
driver to find out about this.
* Removed some variants of the SYS_GETINFO calls from the kernel;
replaced them with new PM and utils libary functionality. Fixed
bugs in utils library that used old get_kenv() variant.
* Implemented a buffer in the kernel to gather random data.
Memory driver periodically checks this for /dev/random.
A better random algorithm can now be implemented in the driver.
Removed SYS_RANDOM; the SYS_GETINFO call is used instead.
* Remove SYS_KMALLOC from the kernel. Memory allocation can now
be done at the process manager with new 'other' library functions.
names. All system processes can now either use panic() or report() from
libutils, or redefine their own function. Assertions are done via the standard
<assert.h> functionality.
