3156  ==============  RELEASE 0.4.3  ==============  ==============  RELEASE 0.4.3  ==============
3158    20061107        Adding a new disk image option (-d o...) which sets the ISO9660
3159                    filesystem base offset; also making some other hacks to allow
3160                    NetBSD/dreamcast and homebrew demos/games to boot directly
3161                    from a filesystem image.
3162                    Moving Dreamcast-specific stuff in the documentation to its
3163                    own page (dreamcast.html).
3164                    Adding a border to the Dreamcast PVR framebuffer.
3165    20061108        Adding a -T command line option (again?), for halting the
3166                    emulator on unimplemented memory accesses.
3167    20061109        Continuing on various SH4 and Dreamcast related things.
3168                    The emulator should now halt on more unimplemented device
3169                    accesses, instead of just printing a warning, forcing me to
3170                    actually implement missing stuff :)
3171    20061111        Continuing on SH4 and Dreamcast stuff.
3172                    Adding a bogus Landisk (SH4) machine mode.
3173    20061112        Implementing some parts of the Dreamcast GDROM device. With
3174                    some ugly hacks, NetBSD can (barely) mount an ISO image.
3175    20061113        NetBSD/dreamcast now starts booting from the Live CD image,
3176                    but crashes randomly quite early on in the boot process.
3177    20061122        Beginning on a skeleton interrupt.h and interrupt.c for the
3178                    new interrupt subsystem.
3179    20061124        Continuing on the new interrupt system; taking the first steps
3180                    to attempt to connect CPUs (SuperH and MIPS) and devices
3181                    (dev_cons and SH4 timer interrupts) to it. Many things will
3182                    probably break from now on.
3183    20061125        Converting dev_ns16550, dev_8253 to the new interrupt system.
3184                    Attempting to begin to convert the ISA bus.
3185    20061130        Incorporating a patch from Brian Foley for the configure
3186                    script, which checks for X11 libs in /usr/X11R6/lib64 (which
3187                    is used on some Linux systems).
3188    20061227        Adding a note in the man page about booting from Dreamcast
3189                    CDROM images (i.e. that no external kernel is needed).
3190    20061229        Continuing on the interrupt system rewrite: beginning to
3191                    convert more devices, adding abort() calls for legacy interrupt
3192                    system calls so that everything now _has_ to be rewritten!
3193                    Almost all machine modes are now completely broken.
3194    20061230        More progress on removing old interrupt code, mostly related
3195                    to the ISA bus + devices, the LCA bus (on AlphaBook1), and
3196                    the Footbridge bus (for CATS). And some minor PCI stuff.
3197                    Connecting the ARM cpu to the new interrupt system.
3198                    The CATS, NetWinder, and QEMU_MIPS machine modes now work with
3199                    the new interrupt system :)
3200    20061231        Connecting PowerPC CPUs to the new interrupt system.
3201                    Making PReP machines (IBM 6050) work again.
3202                    Beginning to convert the GT PCI controller (for e.g. Malta
3203                    and Cobalt emulation). Some things work, but not everything.
3204                    Updating Copyright notices for 2007.
3205    20070101        Converting dev_kn02 from legacy style to devinit; the 3max
3206                    machine mode now works with the new interrupt system :-]
3207    20070105        Beginning to convert the SGI O2 machine to the new interrupt
3208                    system; finally converting O2 (IP32) devices to devinit, etc.
3209    20070106        Continuing on the interrupt system redesign/rewrite; KN01
3210                    (PMAX), KN230, and Dreamcast ASIC interrupts should work again,
3211                    moving out stuff from machine.h and devices.h into the
3212                    corresponding devices, beginning the rewrite of i80321
3213                    interrupts, etc.
3214    20070107        Beginning on the rewrite of Eagle interrupt stuff (PReP, etc).
3215    20070117        Beginning the rewrite of Algor (V3) interrupts (finally
3216                    changing dev_v3 into devinit style).
3217    20070118        Removing the "bus" registry concept from machine.h, because
3218                    it was practically meaningless.
3219                    Continuing on the rewrite of Algor V3 ISA interrupts.
3220    20070121        More work on Algor interrupts; they are now working again,
3221                    well enough to run NetBSD/algor. :-)
3222    20070122        Converting VR41xx (HPCmips) interrupts. NetBSD/hpcmips
3223                    can be installed using the new interrupt system :-)
3224    20070123        Making the testmips mode work with the new interrupt system.
3225    20070127        Beginning to convert DEC5800 devices to devinit, and to the
3226                    new interrupt system.
3227                    Converting Playstation 2 devices to devinit, and converting
3228                    the interrupt system. Also fixing a severe bug: the interrupt
3229                    mask register on Playstation 2 is bitwise _toggled_ on writes.
3230    20070128        Removing the dummy NetGear machine mode and the 8250 device
3231                    (which was only used by the NetGear machine).
3232                    Beginning to convert the MacPPC GC (Grand Central) interrupt
3233                    controller to the new interrupt system.
3234                    Converting Jazz interrupts (PICA61 etc.) to the new interrupt
3235                    system. NetBSD/arc can be installed again :-)
3236                    Fixing the JAZZ timer (hardcoding it at 100 Hz, works with
3237                    NetBSD and it is better than a completely dummy timer as it
3238                    was before).
3239                    Converting dev_mp to the new interrupt system, although I
3240                    haven't had time to actually test it yet.
3241                    Completely removing src/machines/interrupts.c, cpu_interrupt
3242                    and cpu_interrupt_ack in src/cpu.c, and
3243                    src/include/machine_interrupts.h! Adding fatal error messages
3244                    + abort() in the few places that are left to fix.
3245                    Converting dev_z8530 to the new interrupt system.
3246                    FINALLY removing the md_int struct completely from the
3247                    machine struct.
3248                    SH4 fixes (adding a PADDR invalidation in the ITLB replacement
3249                    code in memory_sh.c); the NetBSD/dreamcast LiveCD now runs
3250                    all the way to the login prompt, and can be interacted with :-)
3251                    Converting the CPC700 controller (PCI and interrupt controller
3252                    for PM/PPC) to the new interrupt system.
3253    20070129        Fixing MACE ISA interrupts (SGI IP32 emulation). Both NetBSD/
3254                    sgimips' and OpenBSD/sgi's ramdisk kernels can now be
3255                    interacted with again.
3256    20070130        Moving out the MIPS multi_lw and _sw instruction combinations
3257                    so that they are auto-generated at compile time instead.
3258    20070131        Adding detection of amd64/x86_64 hosts in the configure script,
3259                    for doing initial experiments (again :-) with native code
3260                    generation.
3261                    Adding a -k command line option to set the size of the dyntrans
3262                    cache, and a -B command line option to disable native code
3263                    generation, even if GXemul was compiled with support for
3264                    native code generation for the specific host CPU architecture.
3265    20070201        Experimenting with a skeleton for native code generation.
3266                    Changing the default behaviour, so that native code generation
3267                    is now disabled by default, and has to be enabled by using
3268                    -b on the command line.
3269    20070202        Continuing the native code generation experiments.
3270                    Making PCI interrupts work for Footbridge again.
3271    20070203        More native code generation experiments.
3272                    Removing most of the native code generation experimental code,
3273                    it does not make sense to include any quick hacks like this.
3274                    Minor cleanup/removal of some more legacy MIPS interrupt code.
3275    20070204        Making i80321 interrupts work again (for NetBSD/evbarm etc.),
3276                    and fixing the timer at 100 Hz.
3277    20070206        Experimenting with removing the wdc interrupt slowness hack.
3278    20070207        Lowering the number of dyntrans TLB entries for MIPS from
3279                    192 to 128, resulting in a minor speed improvement.
3280                    Minor optimization to the code invalidation routine in
3281                    cpu_dyntrans.c.
3282    20070208        Increasing (experimentally) the nr of dyntrans instructions per
3283                    loop from 60 to 120.
3284    20070210        Commenting out (experimentally) the dyntrans_device_danger
3285                    detection in memory_rw.c.
3286                    Changing the testmips and baremips machines to use a revision 2
3287                    MIPS64 CPU by default, instead of revision 1.
3288                    Removing the dummy i960, IA64, x86, AVR32, and HP PA-RISC
3289                    files, the PC bios emulation, and the Olivetti M700 (ARC) and
3290                    db64360 emulation modes.
3291    20070211        Adding an "mp" demo to the demos directory, which tests the
3292                    SMP functionality of the testmips machine.
3293                    Fixing PReP interrupts some more. NetBSD/prep now boots again.
3294    20070216        Adding a "nop workaround" for booting Mach/PMAX to the
3295                    documentation; thanks to Artur Bujdoso for the values.
3296                    Converting more of the MacPPC interrupt stuff to the new
3297                    system.
3298                    Beginning to convert BeBox interrupts to the new system.
3299                    PPC603e should NOT have the PPC_NO_DEC flag! Removing it.
3300                    Correcting BeBox clock speed (it was set to 100 in the NetBSD
3301                    bootinfo block, but should be 33000000/4), allowing NetBSD
3302                    to start without using the (incorrect) PPC_NO_DEC hack.
3303    20070217        Implementing (slow) AltiVec vector loads and stores, allowing
3304                    NetBSD/macppc to finally boot using the GENERIC kernel :-)
3305                    Updating the documentation with install instructions for
3306                    NetBSD/macppc.
3307    20070218-19     Regression testing for the release.
