o only include it in the BUILD_DEFS if the current platform is concerned.
For now that only includes i386, but we might find amd64 users in the
future.
o test against [Yy][Ee][Ss], for consistency.
Fixes part of PR 26243.
2004/07/06 - version 0.8.9beta released
Great bug fixes:
o JIT CPU is working on Linux 2.6.x
o Blitter is finally not crashing anymore
o integrated LILO (Linux Loader) reads gzipped files
o SDL GUI now accepts numbers typed on numpad
Especially the Blitter fix itself justifies a new release
since it has always been buggy and it was so annoying. Now we've won.
ARAnyM is an acronym: Atari Running on Any Machine. It is a virtual machine
software for running the Atari ST/TT/Falcon operating systems (TOS, FreeMiNT,
MagiC and others) and TOS/GEM applications on any kind of hardware - be it
an IBM clone (read it as "PC" :-), an Apple, an Unix server, a graphics
workstation or even a portable computer.
20040701 The -j option now takes a name, the of the kernel as passed
on to the bootloader. ("netbsd" is the default name.)
Adding support to load bootstrap code directly from a disk
image, for DECstation. Both NetBSD/pmax and Ultrix boot
straight of a disk image now, with no need to supply a
kernel filename on the command line. (Ultrix still needs
-j vmunix, though, to boot from /vmunix instead of /netbsd.)
20040702 Minor bugfix (some new untested code for X11 keypresses was
incorrect).
20040702(later) Adding an ugly hack for CDROMs in FreeBSD; if an fread() isn't
done at a 2048-byte aligned offset, it will fail. The hack
tries to read at 2048-byte aligned offsets and move around
buffers to make it work.
Adding video off (screen blanking) support to BT459.
Making a 0.1.1 release.
In mips64emul's current state, it is possible to emulate a DECstation well
enough to let NetBSD/pmax install itself onto a harddisk image, in a manner
very similar to how an install is performed on a real physical DECstation.
(Ultrix/RISC is also possible to install this way.)
Changes:
27 Jun 2004:
(Early.) I found and fixed an interrupt related bug in the BT459 ramdac
device, which affected the performance of any machine using the PMAG-BA
negatively (that means DECstations), so now Ultrix 4.2 boots into graphical
login in about 25 seconds! Wow. For X11 bitdepths other than 8 or 24, a
warning message is printed at startup. Adding a BUGS file containing a
list of known bugs. I'm doing a lot of other minor fixes, optimizations,
and beautifying of the code as well. I measured the time of another full
NetBSD 1.6.2 install, on the same host and with the same compiler as on
the 24th of June:
Runtime flags: -CR4000 -D2 -q -M32 -I6000000
Total install time (NetBSD 1.6.2, silent mode): about 50 minutes
Total time until the login prompt appears: about 2 minutes
(This is with -CR4000 and without -X.)
Compiling the emulator inside itself: 1.5 hours
-fomit-frame-pointer is now enabled by default by the configure script,
if the C compiler supports it. Adding a minimal man page, doc/mips64emul.1.
25 Jun 2004:
(Later) Adding a -v (verbose) command line option. If -v is not specified,
the emulator goes into -q (quiet) mode just before it starts to execute
MIPS code.
buildlink3.mk files.
on NetBSD and others this was building and working but resolving symbols
from libgcrypt and libgpg-error indirectly via libspectrum. this is not
good practice, you must always explicitly link against libraries for the
functions you need.
fixes the build on Solaris.
bump PKGREVISION.
Changes:
23 Jun 2004:
(Early in the morning.) Performing a general code cleanup (comments,
fixing stuff that led to compiler warnings, ...).
Disabling MIPS16 support by default, and making it a configure time
option to enable it (--mips16). This gives a few percent speed increase
overall. Increasing performance by assuming that instruction loads
(reading from memory) will be at the same page as the last load.
First by assuming that a vaddr -> paddr translation for instruction
loads almost always is preserved (gaining a few percent speed), and
then that a paddr -> host memblock translation also holds if the
instruction is in normal RAM (which led to some more percents of speed
increase). :-) This is definitely a fine night for coding...
For example, the total time from starting the emulator until Ultrix 4.
2 shows it graphical login dialog is 48 seconds!
22 Jun 2004:
(Late.) Trying to track down the last SCSI tape bugs. Removing all
dynamic binary translation code (bintrans), starting from scratch again.
22 Jun 2004:
(Early in the morning.) Finally! After many many hours of trial and
error, I got the SCSI tape stuff to work; when going past the end of a
file, automagically switch to the beginning of the next.
21 Jun 2004:
Removing the Nintendo 64 emulation mode, as it is too uninteresting to
support. Adding SCSI tape device support (read-only, so far, and not
100% working). Fixing a bug which caused the cursor to be corrupted if
new data was written to the framebuffer, but the cursor wasn't moved.
20 Jun 2004:
Adding a program which converts SGI prom dumps from text capture to
binary, and some hacks to try to make such an IP22 PROM to work better
in the emulator.
Changes since 0.82.1:
* Everything from MAME 0.83 and MESS 0.83 (changes-mess.html).
* The Xv driver now turns on XV_AUTOPAINT_COLORKEY, in case it was
turned off by, for example, by the xine movie player. This prevents the
display from being blank in this case. (Shyouzou Sugitani)

messages to display and slowing down the emulation for some games.
mips64emul is a MIPS machine emulator. The goals are to emulate 32-bit and
64-bit MIPS CPUs and enough surrounding hardware to fake real machines,
capable of running real (unmodified) operating systems, such as NetBSD or
Linux.
