==================MK83A=============================
New features:
--- --------
MiG has new syntax to align fields on arbitrary (power-of-2) boundaries,
so that (for example) a structure of 32-bit integers can be aligned
on either a 64-bit or a 32-bit boundary on the Alpha. The syntax
is:
<type> = (<type name>, <size in bits>, <alignment boundary in bits>)
Added the scripts and auxilary build tools to flatten the MK
source tree and build with the NetBSD make files.
Added the sources for a NetBSD boot program that will boot both
MK and a vanilla NetBSD kernel
Added a few changes from Johannes Helander to support LITES
[I386AT] now supports the AHA17 32-bit SCSI adapter.
[I386PS2] now supports the Ethernet adapter.
Bug fixes:
--- -----
The 'device_write' bug HAS been fixed. If the memory given to
device_write_request is changed before the hardware has completed the
IO, the user wil be forced to wait for the hardware IO to be done.
The bug was in vm_copyin_to_page_list.
host_info() now correctly returns min_timeout and min_quantum in
milliseconds, as per the documentation. These values, however,
are somewhat arbitrary: min_timeout depends on the current resolution
of the system clock, and the quantum varies on multiprocessors.
The 'audio' device ignores drops: "it is less irritating to
hear a glitch than to speed-ahead an entire block of samples"
(Alessandro Forin).
[ALPHA] 'catch_exception_raise' has been made 64-bit clean: the
'exception', 'code', and 'subcode' arguments are now
longs, since 'subcode' contains a virtual address for
EXC_BAD_ADDRESS. This is an INCOMPATIBLE change, however;
all programs that use 'exc_server' and 'catch_exception_raise'
(and 'exc_user') MUST be relinked. As a result, MK84 will
NOT work with the current UX server (UX42 and below). There
will be a UX release in the very near future that works with
MK84 on the Alpha.
Special notes:
------- -----
Built and tested on i386AT, i386PS2, Sequent, DecStation 5000/120,
Dec Alpha.
The list of machines that CMU supports has once again dropped. We
now build for the I386 (ISA and PS/2), various flavors of Decstations
(the MIPS R2000/R3000 processors), and the Dec Alpha (with Turbochannel).
This release has been built and tested for the Sequent Symmetry. However,
since our Sequent has broken, it is unlikely that future releases will
be built for it.
We no longer support the Omron Luna88k. The kernel has been compiled
for the Luna88k, but not run.

[93/12/13 rvb] *********** &
Upgrade for NetBSD 0.9 and "md".
------------------------
./kernel/device/bpf.h
Changed 'long' to 'int' for 64-bit cleanup.
(perhaps we should use int32?)

------------------------
./kernel/i386/db_interface.c
ANSI-fied.
[93/11/03 dbg]

controlled by the global variable db_no_vm_fault, same as mips/alpha.
[93/09/25 af]
------------------------
./kernel/i386/db_trace.c
Reorganized a little, splitting out db_i386_stack_trace().
Added Cthreads debugging support.
[93/09/24 af]
------------------------
./kernel/i386/interrupt.s
PIC addresses are constants (and known to be <= 0xff), so they
can be used as immediate addresses in IN and OUT instructions.
[93/10/29 dbg]
The reason that the spurious interrupt check has never worked is
that the non-specific EOI has already CLEARED the ISR bit that we
are checking!
[93/10/25 dbg]
Changes from ralf@chpc.org: handle spuroius interrupts
generated by Adaptec 174x.
[93/10/20 13:03:31 af]
------------------------
./kernel/i386/iopb.c
Never allow access to IO ports 0x00 .. 0xff. These are system
control ports on PCs. Clobbering configuration info in CMOS may
make the machine unusable!
[93/10/20 dbg]
Removed lint.
[93/06/17 dbg]
------------------------
./kernel/i386/user_ldt.c
Fixed bug in i386_set_ldt: descriptors were being copied into
the old LDT (which was sometimes NULL), thus being thrown away
(!).
[93/09/10 dbg]
Removed lint.
[93/06/17 dbg]
------------------------
./kernel/i386at/autoconf.c
Added 174x driver (dherity@cs.tcd.ie & ralf@chpc.org)
[93/10/06 af]

[93/05/06 09:30:11 af]
------------------------
./kernel/i386at/boot/Makefile
Update for odemake.
[93/11/08 mrt]
------------------------
./kernel/i386at/boot/Makefile.bnr
Upgrade for NetBSD 0.9 and "md".
[93/12/13 rvb]
------------------------
./kernel/i386at/com.c
Restore earlier fix: can`t use ttymodem "flow control" since
modem drops carrier but still talks to machine. Shut down FIFO
on close.
[93/06/15 dbg]
Include kern/time_out.h for hz. *********
[93/06/04 dbg]
------------------------
./kernel/i386at/eisa.h
RCSed. Presumably Philippe Bernadat wrote this.
[93/10/20 af]
------------------------
./kernel/i386at/iopl.c
Changed mmap routines to return physical address instead of *************!!
physical page number.
[93/05/24 dbg]
Remove CMOS from IO port list, since kernel uses it as a clock.
Autoconfig should remove in-use IO ports from list as it finds
devices.
[93/05/14 dbg]
------------------------
./kernel/i386ps2/if_en.c
Changed start() to return void.
[93/09/13 dbg]
Created, used if_pc586 as a reference.
[93/09/09 zon]
------------------------
./kernel/kern/exception.c
Use 'MACH_MSG_TYPE_INTEGER_T' for type of integer_t.
[93/11/19 dbg]
64-bit cleanup. Subcode must be integer_t, since it holds an
address for EXC_BAD_ADDRESS. I made exception and code be
natural_t for consistency.
[93/11/09 dbg]
Use thread_lock instead of ith_lock, task_lock instead of *********** &
itk_lock.
[93/07/12 dbg]
Declared continuation functions as not returning. *********** &
[93/05/04 dbg]
Added ANSI function prototypes. Removed include of *********** &
kern/sched.h. Removed KEEP_STACKS code.
[93/03/25 dbg]
------------------------
./kernel/kern/host.c
Get min_quantum from kern/quantum.h. ***********
[93/05/11 dbg]
Fixed host_info to correctly return min_timeout and min_quantum ***********
in milliseconds. Added ANSI function prototypes.
[93/01/27 dbg]
------------------------
./kernel/kern/pc_sample.c
Made file still build when MACH_PCSAMPLE == 0. Added ***********
ANSI function prototypes. Return current system clock
period (in microseconds!) instead of 'tick'.
[93/03/02 dbg]

Surounded typedefs with ifndef ASSEMBLER.
[94/02/11 jvh]
------------------------
./kernel/mach/exc.defs
64-bit cleanup. Subcode must be integer_t, since it holds an
address for EXC_BAD_ADDRESS. I made exception and code be
natural_t for consistency.
------------------------
./kernel/mach/host_info.h
Finished the 64-bit cleanup: made host_sched_info be a struct of
integer_t, since it is passed as a host_info_t.

Moved source into kernel/i386at/DLINK/if_de6c.c, since we
can't release it but don't want to lose it.
[93/11/17 dbg]
Removed u_long.

------------------------
[ ./kernel/scsi/rz_labels.c ]
Need to always keep d_partitions[MAXPARTITIONS] correct, so
always reset it ourselves.

./kernel/src/mig/lexxer.l
stringize() macro for non-STDC preprocessors.
Changed TPRETURN to take an alignment argument.
Fixed all uses accordingly.
[93/09/14 12:52:12 af]
------------------------
./kernel/src/mig/mig.sh
Added -migcom option. The argument specifies where to find it.
Removed dependency of CPP being defined as an environment variable.
[ jvh]
------------------------
./kernel/src/mig/parser.y
Added "alignment" field to symtype.
Pass it to itShortDecl and itLongDecl.
Added production to BasicTypeSpec for
specifying explicitly the alignment.
Verify alignments in IPCType.
[93/09/14 12:50:09 af]
------------------------
./kernel/src/mig/routine.c
Added initializations of argSuffix.
Implemented alignment of basic/defined types.
rtFindSize prints a warning when the new code
and the previous (hack) code differ.
Added workaround for case of polymorphic request/reply
port and suffix code.
[93/09/14 13:02:04 af]
------------------------
./kernel/src/mig/routine.h
Added argSuffix to struct argument.
[93/09/14 12:21:54 af]
------------------------
./kernel/src/mig/server.c
Lots of changes to accomodate screwy GCC compiler on 64bit
machines, who makes improper assumptions about alignments.
The basic idea is to typecast type descriptors as needed.
The argSuffix field helps building the proper reference.
Added WriteMsgFieldRef(). Changed WriteArgSize to take
alignment specifier, and use it.
Added WriteArgSizeStright().
WriteAdjustMsgSize now needs to look-ahead for alignment requirements.
See comments within for 64bit-specific twist.
[93/09/14 12:28:33 af]
------------------------
./kernel/src/mig/string.c
Added strconcat3().
[93/09/14 12:22:21 af]

./kernel/src/mig/user.c
Similarly to changes in server.c (duplications... tzk tzk)
Lots of changes to accomodate screwy GCC compiler on 64bit
machines, who makes improper assumptions about alignments.
The basic idea is to typecast type descriptors as needed.
The argSuffix field helps building the proper reference,
as in WritePackArgValue() for instance.
Added WriteMsgFieldRef(). Changed WriteArgSize to take
alignment specifier, and use it.
Added WriteArgSizeStright().
WriteAdjustMsgSize now needs to look-ahead for alignment requirements.

Give the port name as an argument to mig_dealloc_reply_port. ************&
Call mig_put_reply_port when done with a port allocated by
mig_get_reply_port but mig_dealloc_reply_port is not called.
[94/02/26 jvh]
------------------------
./kernel/src/mig/vprint.c
Added include of strings.h to quiet GCC complains for strlen().
[93/08/28 af]
------------------------
./kernel/vm/vm_map.c
Fixed vm_map_copyin_page_list to write-protect pages that it
finds. This prevents the caller from modifying the page while
the IO device is writing it.
{ The correct code disappeared when vm_map_copyin_page_list went
in... }
Also fixed the src_destroy case of vm_map_copyin to check for
a shared-writable object (object->use_shared_copy) and do
copy-on-write processing if so (a missing part of the share_map
purge).
[93/12/14 dbg]
Conditionalized projected buffer support under NET_ATM.
[93/09/10 dbg]
ANSI-fied.
[93/06/16 dbg]

------------------------
./user/libmach/Makefile ********** &
Renamed 'rt' or 'realtime' threads and timers to 'periodic'
threads and timers (even though they can be used for nonperiodic
threads).
[93/11/16 dbg]

This is needed so that crt0.o and libmach_sa can be
used by the emulator which lives in a high address
quadrant.
