20070501 Continuing a little on m88k disassembly (control registers,
more instructions).
Adding a dummy mvme88k machine mode.
20070502 Re-adding MIPS load/store alignment exceptions.
20070503 Implementing more of the M88K disassembly code.
20070504 Adding disassembly of some more M88K load/store instructions.
Implementing some relatively simple M88K instructions (br.n,
xor[.u] imm, and[.u] imm).
20070505 Implementing M88K three-register and, or, xor, and jmp[.n],
bsr[.n] including function call trace stuff.
Applying a patch from Bruce M. Simpson which implements the
SYSCON_BOARD_CPU_CLOCK_FREQ_ID object of the syscon call in
the yamon PROM emulation.
20070506 Implementing M88K bb0[.n] and bb1[.n], and skeletons for
ldcr and stcr (although no control regs are implemented yet).
20070509 Found and fixed the bug which caused Linux for QEMU_MIPS to
stop working in 0.4.5.1: It was a faulty change to the MIPS
'sc' and 'scd' instructions I made while going through gcc -W
warnings on 20070428.
20070510 Updating the Linux/QEMU_MIPS section in guestoses.html to
use mips-test-0.2.tar.gz instead of 0.1.
A big thank you to Miod Vallat for sending me M88K manuals.
Implementing more M88K instructions (addu, subu, div[u], mulu,
ext[u], clr, set, cmp).
20070511 Fixing bugs in the M88K "and" and "and.u" instructions (found
by comparing against the manual).
Implementing more M88K instructions (mask[.u], mak, bcnd (auto-
generated)) and some more control register details.
Cleanup: Removing the experimental AVR emulation mode and
corresponding devices; AVR emulation wasn't really meaningful.
Implementing autogeneration of most M88K loads/stores. The
rectangle drawing demo (with -O0) for M88K runs :-)
Beginning on M88K exception handling.
More M88K instructions: tb0, tb1, rte, sub, jsr[.n].
Adding some skeleton MVME PROM ("BUG") emulation.
20070512 Fixing a bug in the M88K cmp instruction.
Adding the M88K lda (scaled register) instruction.
Fixing bugs in 64-bit (32-bit pairs) M88K loads/stores.
Removing the unused tick_hz stuff from the machine struct.
Implementing the M88K xmem instruction. OpenBSD/mvme88k gets
far enough to display the Copyright banner :-)
Implementing subu.co (guess), addu.co, addu.ci, ff0, and ff1.
Adding a dev_mvme187, for MVME187-specific devices/registers.
OpenBSD/mvme88k prints more boot messages. :)
20070515 Continuing on MVME187 emulation (adding more devices, beginning
on the CMMUs, etc).
Adding the M88K and.c, xor.c, and or.c instructions, and making
sure that mul, div, etc cause exceptions if executed when SFD1
is disabled.
20070517 Continuing on M88K and MVME187 emulation in general; moving
the CMMU registers to the CPU struct, separating dev_pcc2 from
dev_mvme187, and beginning on memory_m88k.c (BATC and PATC).
Fixing a bug in 64-bit (32-bit pairs) M88K fast stores.
Implementing the clock part of dev_mk48txx.
Implementing the M88K fstcr and xcr instructions.
Implementing m88k_cpu_tlbdump().
Beginning on the implementation of a separate address space
for M88K .usr loads/stores.
20070520 Removing the non-working (skeleton) Sandpoint, SonyNEWS, SHARK
Dnard, and Zaurus machine modes.
Experimenting with dyntrans to_be_translated read-ahead. It
seems to give a very small performance increase for MIPS
emulation, but a large performance degradation for SuperH. Hm.
20070522 Disabling correct SuperH ITLB emulation; it does not seem to be
necessary in order to let SH4 guest OSes run, and it slows down
userspace code.
Implementing "samepage" branches for SuperH emulation, and some
other minor speed hacks.
20070525 Continuing on M88K memory-related stuff: exceptions, memory
transaction register contents, etc.
Implementing the M88K subu.ci instruction.
Removing the non-working (skeleton) Iyonix machine mode.
OpenBSD/mvme88k reaches userland :-), starts executing
/sbin/init's instructions, and issues a few syscalls, before
crashing.
20070526 Fixing bugs in dev_mk48txx, so that OpenBSD/mvme88k detects
the correct time-of-day.
Implementing a generic IRQ controller for the test machines
(dev_irqc), similar to a proposed patch from Petr Stepan.
Experimenting some more with translation read-ahead.
Adding an "expect" script for automated OpenBSD/landisk
install regression/performance tests.
20070527 Adding a dummy mmEye (SH3) machine mode skeleton.
FINALLY found the strange M88K bug I have been hunting: I had
not emulated the SNIP value for exceptions occurring in
branch delay slots correctly.
Implementing correct exceptions for 64-bit M88K loads/stores.
Address to symbol lookups are now disabled when M88K is
running in usermode (because usermode addresses don't have
anything to do with supervisor addresses).
20070531 Removing the mmEye machine mode skeleton.
20070604 Some minor code cleanup.
20070605 Moving src/useremul.c into a subdir (src/useremul/), and
cleaning up some more legacy constructs.
Adding -Wstrict-aliasing and -fstrict-aliasing detection to
the configure script.
20070606 Adding a check for broken GCC on Solaris to the configure
script. (GCC 3.4.3 on Solaris cannot handle static variables
which are initialized to 0 or NULL. :-/)
Removing the old (non-working) ARC emulation modes: NEC RD94,
R94, R96, and R98, and the last traces of Olivetti M700 and
Deskstation Tyne.
Removing the non-working skeleton WDSC device (dev_wdsc).
20070607 Thinking about how to use the host's cc + ld at runtime to
generate native code. (See experiments/native_cc_ld_test.i
for an example.)
20070608 Adding a program counter sampling timer, which could be useful
for native code generation experiments.
The KN02_CSR_NRMMOD bit in the DECstation 5000/200 (KN02) CSR
should always be set, to allow a 5000/200 PROM to boot.
20070609 Moving out breakpoint details from the machine struct into
a helper struct, and removing the limit on max nr of
breakpoints.
20070610 Moving out tick functions into a helper struct as well (which
also gets rid of the max limit).
20070612 FINALLY figured out why Debian/DECstation stopped working when
translation read-ahead was enabled: in src/memory_rw.c, the
call to invalidate_code_translation was made also if the
memory access was an instruction load (if the page was mapped
as writable); it shouldn't be called in that case.
20070613 Implementing some more MIPS32/64 revision 2 instructions: di,
ei, ext, dext, dextm, dextu, and ins.
20070614 Implementing an instruction combination for the NetBSD/arm
idle loop (making the host not use any cpu if NetBSD/arm
inside the emulator is not using any cpu).
Increasing the nr of ARM VPH entries from 128 to 384.
20070615 Removing the ENABLE_arch stuff from the configure script, so
that all included architectures are included in both release
and development builds.
Moving memory related helper functions from misc.c to memory.c.
Adding preliminary instructions for netbooting NetBSD/pmppc to
guestoses.html; it doesn't work yet, there are weird timeouts.
Beginning a total rewrite of the userland emulation modes
(removing all emulation modes, beginning from scratch with
NetBSD/MIPS and FreeBSD/Alpha only).
20070616 After fixing a bug in the DEC21143 NIC (the TDSTAT_OWN bit was
only cleared for the last segment when transmitting, not all
segments), NetBSD/pmppc boots with root-on-nfs without the
timeouts. Updating guestoses.html.
Removing the skeleton PSP (Playstation Portable) mode.
Moving X11-related stuff in the machine struct into a helper
struct.
Cleanup of out-of-memory checks, to use a new CHECK_ALLOCATION
macro (which prints a meaningful error message).
Adding a COMMENT to each machine and device (for automagic
.index comment generation).
Doing regression testing for the next release.

$Id: HISTORY,v 1.1515 2007/04/14 05:39:46 debug Exp $
20070324 Adding a "--debug" option to the configure script, to disable
optimizations in unstable development builds.
Moving out SCSI-specific stuff from diskimage.c into a new
diskimage_scsicmd.c.
Applying Hĺvard Eidnes' patch for SCSICDROM_READ_DISKINFO and
SCSICDROM_READ_TRACKINFO. (Not really tested yet.)
Implementing disk image "overlays" (to allow simple roll-back
to previous disk state). Adding a 'V' disk flag for this, and
updating the man page and misc.html.
20070325 Stability fix to cpu_dyntrans.c, when multiple physical pages
share the same initial table entry. (The ppp == NULL check
should be physpage_ofs == 0.) Bug found by analysing GXemul
against a version patched for Godson.
Fixing a second occurance of the same problem (also in
cpu_dyntrans.c).
Fixing a MAJOR physical page leak in cpu_dyntrans.c; pages
weren't _added_ to the set of translated pages, they _replaced_
all previous pages. It's amazing that this bug has been able
to live for this long. (Triggered when emulating >128MB RAM.)
20070326 Removing the GDB debugging stub support; it was too hackish
and ugly.
20070328 Moving around some native code generation skeleton code.
20070329 The -lm check in the configure script now also checks for sin()
in addition to sqrt(). (Thanks to Nigel Horne for noticing that
sqrt was not enough on Fedora Core 6.) (Not verified yet.)
20070330 Fixing an indexing bug in dev_sh4.c, found by using gcc version
4.3.0 20070323.
20070331 Some more experimentation with native code generation.
20070404 Attempting to fix some more SH4 SCIF interrupt bugs; rewriting
the SH interrupt assertion/deassertion code somewhat.
20070410 Splitting src/file.c into separate files in src/file/.
Cleanup: Removing the dummy TS7200, Walnut, PB1000, and
Meshcube emulation modes, and dev_epcom and dev_au1x00.
Removing the experimental CHIP8/RCA180x code; it wasn't really
working much lately, anyway. It was fun while it lasted.
Also removing the experimental Transputer CPU support.
20070412 Moving the section about how the dynamic translation system
works from intro.html to a separate translation.html file.
Minor SH fixes; attempting to get OpenBSD/landisk to run
without randomly bugging out, but no success yet.
20070413 SH SCI (serial bit interface) should now work together with a
(new) RS5C313 clock device (for Landisk emulation).
20070414 Moving Redhat/MIPS down from supported to experimental, in
guestoses.html.
Preparing for a new release; doing some regression testing etc.

$Id: HISTORY,v 1.1480 2007/02/19 01:34:42 debug Exp $
20061029 Changing usleep(1) calls in the debugger to usleep(10000)
20061107 Adding a new disk image option (-d o...) which sets the ISO9660
filesystem base offset; also making some other hacks to allow
NetBSD/dreamcast and homebrew demos/games to boot directly
from a filesystem image.
Moving Dreamcast-specific stuff in the documentation to its
own page (dreamcast.html).
Adding a border to the Dreamcast PVR framebuffer.
20061108 Adding a -T command line option (again?), for halting the
emulator on unimplemented memory accesses.
20061109 Continuing on various SH4 and Dreamcast related things.
The emulator should now halt on more unimplemented device
accesses, instead of just printing a warning, forcing me to
actually implement missing stuff :)
20061111 Continuing on SH4 and Dreamcast stuff.
Adding a bogus Landisk (SH4) machine mode.
20061112 Implementing some parts of the Dreamcast GDROM device. With
some ugly hacks, NetBSD can (barely) mount an ISO image.
20061113 NetBSD/dreamcast now starts booting from the Live CD image,
but crashes randomly quite early on in the boot process.
20061122 Beginning on a skeleton interrupt.h and interrupt.c for the
new interrupt subsystem.
20061124 Continuing on the new interrupt system; taking the first steps
to attempt to connect CPUs (SuperH and MIPS) and devices
(dev_cons and SH4 timer interrupts) to it. Many things will
probably break from now on.
20061125 Converting dev_ns16550, dev_8253 to the new interrupt system.
Attempting to begin to convert the ISA bus.
20061130 Incorporating a patch from Brian Foley for the configure
script, which checks for X11 libs in /usr/X11R6/lib64 (which
is used on some Linux systems).
20061227 Adding a note in the man page about booting from Dreamcast
CDROM images (i.e. that no external kernel is needed).
20061229 Continuing on the interrupt system rewrite: beginning to
convert more devices, adding abort() calls for legacy interrupt
system calls so that everything now _has_ to be rewritten!
Almost all machine modes are now completely broken.
20061230 More progress on removing old interrupt code, mostly related
to the ISA bus + devices, the LCA bus (on AlphaBook1), and
the Footbridge bus (for CATS). And some minor PCI stuff.
Connecting the ARM cpu to the new interrupt system.
The CATS, NetWinder, and QEMU_MIPS machine modes now work with
the new interrupt system :)
20061231 Connecting PowerPC CPUs to the new interrupt system.
Making PReP machines (IBM 6050) work again.
Beginning to convert the GT PCI controller (for e.g. Malta
and Cobalt emulation). Some things work, but not everything.
Updating Copyright notices for 2007.
20070101 Converting dev_kn02 from legacy style to devinit; the 3max
machine mode now works with the new interrupt system :-]
20070105 Beginning to convert the SGI O2 machine to the new interrupt
system; finally converting O2 (IP32) devices to devinit, etc.
20070106 Continuing on the interrupt system redesign/rewrite; KN01
(PMAX), KN230, and Dreamcast ASIC interrupts should work again,
moving out stuff from machine.h and devices.h into the
corresponding devices, beginning the rewrite of i80321
interrupts, etc.
20070107 Beginning on the rewrite of Eagle interrupt stuff (PReP, etc).
20070117 Beginning the rewrite of Algor (V3) interrupts (finally
changing dev_v3 into devinit style).
20070118 Removing the "bus" registry concept from machine.h, because
it was practically meaningless.
Continuing on the rewrite of Algor V3 ISA interrupts.
20070121 More work on Algor interrupts; they are now working again,
well enough to run NetBSD/algor. :-)
20070122 Converting VR41xx (HPCmips) interrupts. NetBSD/hpcmips
can be installed using the new interrupt system :-)
20070123 Making the testmips mode work with the new interrupt system.
20070127 Beginning to convert DEC5800 devices to devinit, and to the
new interrupt system.
Converting Playstation 2 devices to devinit, and converting
the interrupt system. Also fixing a severe bug: the interrupt
mask register on Playstation 2 is bitwise _toggled_ on writes.
20070128 Removing the dummy NetGear machine mode and the 8250 device
(which was only used by the NetGear machine).
Beginning to convert the MacPPC GC (Grand Central) interrupt
controller to the new interrupt system.
Converting Jazz interrupts (PICA61 etc.) to the new interrupt
system. NetBSD/arc can be installed again :-)
Fixing the JAZZ timer (hardcoding it at 100 Hz, works with
NetBSD and it is better than a completely dummy timer as it
was before).
Converting dev_mp to the new interrupt system, although I
haven't had time to actually test it yet.
Completely removing src/machines/interrupts.c, cpu_interrupt
and cpu_interrupt_ack in src/cpu.c, and
src/include/machine_interrupts.h! Adding fatal error messages
+ abort() in the few places that are left to fix.
Converting dev_z8530 to the new interrupt system.
FINALLY removing the md_int struct completely from the
machine struct.
SH4 fixes (adding a PADDR invalidation in the ITLB replacement
code in memory_sh.c); the NetBSD/dreamcast LiveCD now runs
all the way to the login prompt, and can be interacted with :-)
Converting the CPC700 controller (PCI and interrupt controller
for PM/PPC) to the new interrupt system.
20070129 Fixing MACE ISA interrupts (SGI IP32 emulation). Both NetBSD/
sgimips' and OpenBSD/sgi's ramdisk kernels can now be
interacted with again.
20070130 Moving out the MIPS multi_lw and _sw instruction combinations
so that they are auto-generated at compile time instead.
20070131 Adding detection of amd64/x86_64 hosts in the configure script,
for doing initial experiments (again :-) with native code
generation.
Adding a -k command line option to set the size of the dyntrans
cache, and a -B command line option to disable native code
generation, even if GXemul was compiled with support for
native code generation for the specific host CPU architecture.
20070201 Experimenting with a skeleton for native code generation.
Changing the default behaviour, so that native code generation
is now disabled by default, and has to be enabled by using
-b on the command line.
20070202 Continuing the native code generation experiments.
Making PCI interrupts work for Footbridge again.
20070203 More native code generation experiments.
Removing most of the native code generation experimental code,
it does not make sense to include any quick hacks like this.
Minor cleanup/removal of some more legacy MIPS interrupt code.
20070204 Making i80321 interrupts work again (for NetBSD/evbarm etc.),
and fixing the timer at 100 Hz.
20070206 Experimenting with removing the wdc interrupt slowness hack.
20070207 Lowering the number of dyntrans TLB entries for MIPS from
192 to 128, resulting in a minor speed improvement.
Minor optimization to the code invalidation routine in
cpu_dyntrans.c.
20070208 Increasing (experimentally) the nr of dyntrans instructions per
loop from 60 to 120.
20070210 Commenting out (experimentally) the dyntrans_device_danger
detection in memory_rw.c.
Changing the testmips and baremips machines to use a revision 2
MIPS64 CPU by default, instead of revision 1.
Removing the dummy i960, IA64, x86, AVR32, and HP PA-RISC
files, the PC bios emulation, and the Olivetti M700 (ARC) and
db64360 emulation modes.
20070211 Adding an "mp" demo to the demos directory, which tests the
SMP functionality of the testmips machine.
Fixing PReP interrupts some more. NetBSD/prep now boots again.
20070216 Adding a "nop workaround" for booting Mach/PMAX to the
documentation; thanks to Artur Bujdoso for the values.
Converting more of the MacPPC interrupt stuff to the new
system.
Beginning to convert BeBox interrupts to the new system.
PPC603e should NOT have the PPC_NO_DEC flag! Removing it.
Correcting BeBox clock speed (it was set to 100 in the NetBSD
bootinfo block, but should be 33000000/4), allowing NetBSD
to start without using the (incorrect) PPC_NO_DEC hack.
20070217 Implementing (slow) AltiVec vector loads and stores, allowing
NetBSD/macppc to finally boot using the GENERIC kernel :-)
Updating the documentation with install instructions for
NetBSD/macppc.
20070218-19 Regression testing for the release.
