o) SuperH (SH4) emulation is now somewhat more stable.
x) GXemul 0.4.4: A NetBSD/dreamcast Live CD works.
x) GXemul 0.4.4.1: A Linux/dreamcast Live CD also works.
o) PowerPC "G4" emulation is now stable enough to let NetBSD/macppc
run from a disk image. (Installing actually worked before, but the
NetBSD/macppc GENERIC kernel uses AltiVec instructions which were
not implemented correctly.)
o) The PICA-61 (arc) and i80321 (evbarm) emulation modes now have their
timers fixed at 100 Hz. A hardcoded speed like this is very ugly, but
it is at least better than before (when the timer wasn't really
running at any specific speed at all).

Or1ksim is a generic OpenRISC 1000 architecture simulator capable of
emulating OpenRISC based computer systems. Or1ksim provides several
unique features:
* Free, open source code
* High level, fast, architecture simulation that allows early code
analysis and system performance evaluation
* All major models of OpenCores peripheral and system controller
cores supported
* Easy addition of new peripheral models
* Remote debugging through a network socket with the GNU Debugger (GDB)
* Support for different environments (memory configurations and
sizes, OR1K processor model, configuration of peripheral
devices)
Changes between release 0.4.3 and 0.4.4 include, among other things:
o) The interrupt subsystem has been redesigned. This means two things:
x) Internal code cleanup, which makes the whole emulator more
maintainable. Instead of using magically encoded integers
for interrupts, strings are now used. These strings are in
the form of "paths", so that devices and busses can more
easily be connected to other busses, devices, or CPUs.
x) Some machine types which happened to work in release 0.4.3,
but were not listed in the documentation as working, may
have stopped working now. As always, the documentation should
indicate the combinations of machine modes and guest OSes that
are supposed to work.
o) SuperH (SH4) emulation is now somewhat more stable, enough to let a
NetBSD/dreamcast Live CD be usable.
o) PowerPC "G4" emulation is now stable enough to let NetBSD/macppc
run from a disk image. (Installing actually worked before, but the
NetBSD/macppc GENERIC kernel uses AltiVec instructions which were
not implemented correctly.)
o) The PICA-61 (arc) and i80321 (evbarm) emulation modes now have their
timers fixed at 100 Hz. A hardcoded speed like this is very ugly, but
it is at least better than before (when the timer wasn't really
running at any specific speed at all).
- Many Direct3D fixes and performance improvements.

- IDL compiler improvements.

to handle this, but it is good (and simple!) enough for now. It'd be
improved by moving some more files around and trying to make it more
consistent with "regular" installs.
The problem is that the build results are completely different under OS X
than those produced in other systems.
Not bumping PKGREVISION because this was unbuildable before.
Changes between release 0.4.2 and 0.4.3 include, among other things:
o) SuperH (SH4) emulation is now stable enough to let a NetBSD/dreamcast
GENERIC_MD (ramdisk) kernel reach userland.
o) There is now a simple framework for letting emulated clocks, as seen
by guest operating systems, run at the same speed as the host clock.
So far, the DECstation, MobilePro (hpcmips), NetWinder, CATS, Malta
(evbmips), Cobalt, Algor, Dreamcast, and testmips machine modes
use the new clock/timer framework.
o) Some changes to the way expressions are evaluated in the built-in
debugger, and some changes in command behaviour:
x) Expressions (including assignments) can now be arbitrarily
complex, using parentheses, and the following operators:
+ - * / % (modulo) ^ (xor) & (and) | (or)
x) Some internal emulator variables can now be read/written using
normal expressions. Examples of commands that did not work
earlier, but should work now:
print verbose
r5 = sp - arch_pagesize * 4
machine[0].statistics_enabled = 1
x) To force a name to be interpreted as a setting/register name,
a hash sign (#) is now used instead of the percentage sign (%).
(In the new expression evaluator, % means arithmetic modulo.)
x) The 'focus' command now also selects a cpu, in addition to
selecting machine and emul.
x) The 'reg' command only prints registers for one cpu now, not
all cpus in the currently focused machine.
o) The wdc (standard IDE controller) had a bug which prevented disk
images larger than 2 GB to work correctly. This has been fixed.
o) For MIPS emulation, some combinations of emulated processor + guest
operating system should now work better when idling (i.e. the host
should not run at 100% CPU):
x) For MIPS32/MIPS64 and RM5200, the 'wait' instruction should
now work more or less as expected.
x) For VR41xx (e.g. MobilePro) emulation, the standby instruction
should work like the 'wait' instruction.
x) For R3000 emulation, where there is no hardware wait instruction,
I've implemented "instruction combination" hacks for both
NetBSD/pmax and Debian/pmax, so that their cpu idle loops are
detected and treated almost as a wait instruction.
o) MIPS 64-bit address translation (X=1) was not fully working before;
TLB exception handling for xkseg and larger-than-2GB-userland should
now actually work. (Thanks to Juli Mallett and Carl van Schaik for
noticing these problems.)
o) The mouse cursor update routines in DECstation (LK201) emulation
previously used the fact that guest OSes set the _hardware_
cursor position. In order to support X Windows when emulating
modern versions of NetBSD/pmax, which don't set the hardware
position anymore, a workaround has been implemented which only
sends relative coordinates to the guest OS. This has two drawbacks:
1. Ultrix emulation with dual- and tripple-head emulation will
most likely feel very strange. It will still work, though.
2. Cursor movement feels "accelerated", because the emulator
sends unaccelerated movements to the guest OS, which then
accelerates them. This can however be compensated to some
degree by running 'xset m 1 0' in the guest OS.
Having weird accelerated mouse movement is better than having no
mouse support at all, so this change was necessary.
- Support for multiple monitors using Xinerama.
- Various MSI fixes and improvements.
- A ton of memory leaks fixed.
- Many common controls fixes.
- Lots of bug fixes.
