|
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. |
| 3308 |
|
|
| 3309 |
|
============== RELEASE 0.4.4 ============== |
| 3310 |
|
|
| 3311 |
|
20070224 Minor update to the initialization of the ns16550 in |
| 3312 |
|
machine_walnut.c, to allow that machine type to boot with the |
| 3313 |
|
new interrupt system (although it is still a dummy machine). |
| 3314 |
|
Adding a wdc at 0x14000000 to machine_landisk.c, and fixing |
| 3315 |
|
the SCIF serial interrupts of the SH4 cpu enough to get |
| 3316 |
|
NetBSD/landisk booting from a disk image :-) Adding a |
| 3317 |
|
preliminary install instruction skeleton to guestoses.html. |
| 3318 |
|
20070306 Adding SH-IPL+G PROM emulation, and also passing the "end" |
| 3319 |
|
symbol in r5 on bootup, for Landisk emulation. This is enough |
| 3320 |
|
to get OpenBSD/landisk to install :) Adding a preliminary |
| 3321 |
|
install instruction skeleton to the documentation. SuperH |
| 3322 |
|
emulation is still shaky, though :-/ |
| 3323 |
|
20070307 Fixed a strangeness in memory_sh.c (read/write was never |
| 3324 |
|
returned for any page). (Unknown whether this fixes any actual |
| 3325 |
|
problems, though.) |
| 3326 |
|
20070308 dev_ram.c fix: invalidate code translations on writes to |
| 3327 |
|
RAM, emulated as separate devices. Linux/dreamcast gets |
| 3328 |
|
further in the boot process than before, but still bugs out |
| 3329 |
|
in userland. |
| 3330 |
|
Fixing bugs in the "stc.l gbr,@-rN" and "ldc.l @rN+,gbr" SuperH |
| 3331 |
|
instructions (they should NOT check the MD bit), allowing the |
| 3332 |
|
Linux/dreamcast Live CD to reach userland correctly :-) |
| 3333 |
|
20070310 Changing the cpu name "Alpha" in src/useremul.c to "21364" to |
| 3334 |
|
unbreak userland syscall emulation of FreeBSD/Alpha binaries. |
| 3335 |
|
20070314 Applying a patch from Michael Yaroslavtsev which fixes the |
| 3336 |
|
previous Linux lib64 patch to the configure script. |
| 3337 |
|
20070315 Adding a (dummy) sun4v machine type, and SPARC T1 cpu type. |
| 3338 |
|
20070316 Creating a new directory, src/disk, and moving diskimage.c |
| 3339 |
|
to it. Separating out bootblock loading stuff from emul.c into |
| 3340 |
|
new files in src/disk. |
| 3341 |
|
Adding some more SPARC registers. |
| 3342 |
|
20070318 Preparing/testing for a minirelease, 0.4.4.1. |
| 3343 |
|
|
| 3344 |
|
============== RELEASE 0.4.4.1 ============== |
| 3345 |
|
|
| 3346 |
|
20070324 Adding a "--debug" option to the configure script, to disable |
| 3347 |
|
optimizations in unstable development builds. |
| 3348 |
|
Moving out SCSI-specific stuff from diskimage.c into a new |
| 3349 |
|
diskimage_scsicmd.c. |
| 3350 |
|
Applying Håvard Eidnes' patch for SCSICDROM_READ_DISKINFO and |
| 3351 |
|
SCSICDROM_READ_TRACKINFO. (Not really tested yet.) |
| 3352 |
|
Implementing disk image "overlays" (to allow simple roll-back |
| 3353 |
|
to previous disk state). Adding a 'V' disk flag for this, and |
| 3354 |
|
updating the man page and misc.html. |
| 3355 |
|
20070325 Stability fix to cpu_dyntrans.c, when multiple physical pages |
| 3356 |
|
share the same initial table entry. (The ppp == NULL check |
| 3357 |
|
should be physpage_ofs == 0.) Bug found by analysing GXemul |
| 3358 |
|
against a version patched for Godson. |
| 3359 |
|
Fixing a second occurance of the same problem (also in |
| 3360 |
|
cpu_dyntrans.c). |
| 3361 |
|
Fixing a MAJOR physical page leak in cpu_dyntrans.c; pages |
| 3362 |
|
weren't _added_ to the set of translated pages, they _replaced_ |
| 3363 |
|
all previous pages. It's amazing that this bug has been able |
| 3364 |
|
to live for this long. (Triggered when emulating >128MB RAM.) |
| 3365 |
|
20070326 Removing the GDB debugging stub support; it was too hackish |
| 3366 |
|
and ugly. |
| 3367 |
|
20070328 Moving around some native code generation skeleton code. |
| 3368 |
|
20070329 The -lm check in the configure script now also checks for sin() |
| 3369 |
|
in addition to sqrt(). (Thanks to Nigel Horne for noticing that |
| 3370 |
|
sqrt was not enough on Fedora Core 6.) (Not verified yet.) |
| 3371 |
|
20070330 Fixing an indexing bug in dev_sh4.c, found by using gcc version |
| 3372 |
|
4.3.0 20070323. |
| 3373 |
|
20070331 Some more experimentation with native code generation. |
| 3374 |
|
20070404 Attempting to fix some more SH4 SCIF interrupt bugs; rewriting |
| 3375 |
|
the SH interrupt assertion/deassertion code somewhat. |
| 3376 |
|
20070410 Splitting src/file.c into separate files in src/file/. |
| 3377 |
|
Cleanup: Removing the dummy TS7200, Walnut, PB1000, and |
| 3378 |
|
Meshcube emulation modes, and dev_epcom and dev_au1x00. |
| 3379 |
|
Removing the experimental CHIP8/RCA180x code; it wasn't really |
| 3380 |
|
working much lately, anyway. It was fun while it lasted. |
| 3381 |
|
Also removing the experimental Transputer CPU support. |
| 3382 |
|
20070412 Moving the section about how the dynamic translation system |
| 3383 |
|
works from intro.html to a separate translation.html file. |
| 3384 |
|
Minor SH fixes; attempting to get OpenBSD/landisk to run |
| 3385 |
|
without randomly bugging out, but no success yet. |
| 3386 |
|
20070413 SH SCI (serial bit interface) should now work together with a |
| 3387 |
|
(new) RS5C313 clock device (for Landisk emulation). |
| 3388 |
|
20070414 Moving Redhat/MIPS down from supported to experimental, in |
| 3389 |
|
guestoses.html. |
| 3390 |
|
Preparing for a new release; doing some regression testing etc. |
| 3391 |
|
|
| 3392 |
|
============== RELEASE 0.4.5 ============== |
| 3393 |
|
|
| 3394 |
|
20070415 Landisk PCLOCK should be 33.33 MHz, not 50 MHz. (This makes |
| 3395 |
|
the clock run at correct speed.) |
| 3396 |
|
FINALLY found and fixed the bug which caused OpenBSD/landisk |
| 3397 |
|
to randomly bug out: an &-sign was missing in the special case |
| 3398 |
|
handling of FPSCR in the 'LDS.L @Rm+,FPSCR' instruction. |
| 3399 |
|
Adding similar special case handling for 'LDC.L @Rm+,SR' |
| 3400 |
|
(calling sh_update_sr() instead of just loading). |
| 3401 |
|
Implementing the 'FCNVSD FPUL,DRn' and 'FCNVDS DRm,FPUL' |
| 3402 |
|
SuperH instructions. |
| 3403 |
|
The 'LDC Rm,SR' instruction now immediately breaks out of the |
| 3404 |
|
dyntrans loop if an interrupt is to be triggered. |
| 3405 |
|
20070416 In memory_rw.c, if mapping a page as writable, make sure to |
| 3406 |
|
invalidate code translations even if the data access was a |
| 3407 |
|
read. |
| 3408 |
|
Minor SuperH updates. |
| 3409 |
|
20070418 Removing the dummy M68K emulation mode. |
| 3410 |
|
Minor SH update (turning unnecessary sts_mach_rn, sts_macl_rn, |
| 3411 |
|
and sts_pr_rn instruction handlers into mov_rm_rn). |
| 3412 |
|
20070419 Beginning to add a skeleton for an M88K mode: Adding a hack to |
| 3413 |
|
allow OpenBSD/m88k a.out binaries to be loaded, and disassembly |
| 3414 |
|
of a few simple 88K instructions. |
| 3415 |
|
Commenting out the 'LDC Rm,SR' fix from a few days ago, because |
| 3416 |
|
it made Linux/dreamcast bug out. |
| 3417 |

Adding a hack to dev_sh4.c (an extra translation cache |
| 3418 |
|
invalidation), which allows OpenBSD/landisk to boot ok after |
| 3419 |
|
an install. Upgrading the Landisk machine mode to stable, |
| 3420 |
|
updating documentation, etc. |
| 3421 |
|
20070420 Experimenting with adding a PCI controller (pcic) to dev_sh4. |
| 3422 |
|
Adding a dummy Realtek 8139C+ skeleton device (dev_rtl8139c). |
| 3423 |
|
Implementing the first M88K instructions (br, or[.u] imm), and |
| 3424 |
|
adding disassembly of some more instructions. |
| 3425 |
|
20070421 Continuing a little on dev_rtl8139c. |
| 3426 |
|
20070422 Implementing the 9346 EEPROM "read" command for dev_rtl8139c. |
| 3427 |
|
Finally found and fixed an old bug in the log n symbol search |
| 3428 |
|
(it sometimes missed symbols). Debug trace (-i, -t etc) should |
| 3429 |
|
now show more symbols. :-) |
| 3430 |
|
20070423 Continuing a little on M88K disassembly. |
| 3431 |
|
20070428 Fixing a memset arg order bug in src/net/net.c (thanks to |
| 3432 |
|
Nigel Horne for noticing the bug). |
| 3433 |
|
Applying parts of a patch from Carl van Schaik to clear out |
| 3434 |
|
bottom bits of MIPS addresses more correctly, when using large |
| 3435 |
|
page sizes, and doing some other minor cleanup/refactoring. |
| 3436 |
|
Fixing a couple of warnings given by gcc with the -W option (a |
| 3437 |
|
few more warnings than just plain -Wall). |
| 3438 |
|
Reducing SuperH dyntrans physical address space from 64-bit to |
| 3439 |
|
32-bit (since SH5/SH64 isn't imlemented yet anyway). |
| 3440 |
|
Adding address-to-symbol annotation to a few more instructions |
| 3441 |
|
in the SuperH instruction trace output. |
| 3442 |
|
Beginning regression testing for the next release. |
| 3443 |
|
Reverting the value of SCIF_DELAYED_TX_VALUE from 1 to 2, |
| 3444 |
|
because OpenBSD/landisk may otherwise hang randomly. |
| 3445 |
|
20070429 The ugly hack/workaround to get OpenBSD/landisk booting without |
| 3446 |
|
crashing does NOT work anymore (with the April 21 snapshot |
| 3447 |
|
of OpenBSD/landisk). Strangely enough, removing the hack |
| 3448 |
|
completely causes OpenBSD/landisk to work (!). |
| 3449 |
|
More regression testing (re-testing everything SuperH-related, |
| 3450 |
|
and some other things). |
| 3451 |
|
Cobalt interrupts were actually broken; fixing by commenting |
| 3452 |
|
out the DEC21143s in the Cobalt machine. |
| 3453 |
|
20070430 More regression testing. |
| 3454 |
|
20070501 Updating the OpenBSD/landisk install instructions to use |
| 3455 |
|
4.1 instead of the current snapshot. |
| 3456 |
|
GAAAH! OpenBSD/landisk 4.1 _needs_ the ugly hack/workaround; |
| 3457 |
|
reintroducing it again. (The 4.1 kernel is actually from |
| 3458 |
|
2007-03-11.) |
| 3459 |
|
Simplifying the NetBSD/evbarm install instructions a bit. |
| 3460 |
|
More regression testing. |
