PC emulator

Changes in 2.3.6 (December 24, 2007):

 

Brief summary :

 

+ More than 25% emulation speedup vs Bochs 2.3.5 release!

 

- Thanks to Darek Mihocka (http://www.emulators.com)

for providing patches and ideas that made the

speedup possible!

 

+ Up to 40% speedup vs Bochs 2.3.5 release with trace cache optimization!

 

- Lots of bugfixes in CPU emulation

- Bochs benchmarking support

- Added emulation of Intel SSE4.2 instruction set

 

Detailed change log :

 

CPU

- Added emulation of SSE4.2 instruction set, to enable use --enable-sse=4 --enable-sse-extension configure options to enable POPCNT instruction only use configure option --enable-popcnt

- Implemented MTRR emulation, to enable use --enable-mtrr configure option. MTRRs is enabled by default when cpu-level >= 6.

- Implemented experimental MONITOR/MWAIT support including optimized MWAIT CPU state and hardware monitoring of physical address range, to enable use --enable-monitor-mwait configure option.

- Removed hostasm optimizations, after Bochs rebenchmarking it was found that the feature bringing no speedup or even sometimes slows down emulation!

- Merged trace cache optimization patch, the trace cache optimization is enabled by default when configure with --enable-all-optimizations option, to disable trace cache optimization configure with --disable-trace-cache

- Many minor bugfixes in CPU emulation (both ia32 and x86-64)

- Updated CPU instrumentation callbacks

 

Bochs Internal Debugger and Disassembler

- Many fixes in Bochs internal debugger and disassembler, some debugger interfaces significantly changed due transition to the param tree architecture

- Added support for restoring of the CPU state from external file directly from Bochs debugger

 

Configure and compile

- Renamed configure option --enable-4meg-pages to --enable-large-pages. The option enables page size extensions (PSE) which refers to 2M pages as well.

- Removed --enable-save-restore configure option, save/restore feature changed to be one of the basic Bochs features and compiled by default for all configurations.

- Added new Bochs benchmark mode. To run Bochs in benchmark mode execute it with new command line option 'bochs -benchmark time'. The emulation will be automatically stopped after 'time' millions of emulation cycles executed.

- Another very useful option for benchmarking of Bochs could be enabled using new 'print_timestamps' directive from .bochsrc: print_timestamps: enable=1

- Added --enable-show-ips option to all configuration scripts used to build release binaries, so all future releases will enjoy IPS display.

- Enable alignment check in the CPU and #AC exception by default for --cpu-level >= 4 (like in real hardware)

Plugin for PCSX2

This is gigaherz here, writing my first ever news post.

 

After more than 4 years working on it in my spare time, and while it still doesn't work as well as peops spu2 or zerospu2, the plugin has finally come to be acceptable enough for public testing.

 

I have to note the plugin has many known issues in specific games, like looping, robotized or jumpy audio, but in others it does its job more than fine and in a few it even manages to get better results than its competitors.

 

For now, you can get binary builds for win32 in here.

 

On a side note, it's Christmas day already, so to everyone who chooses to celebrate it, me and the rest of the PCSX2 team wish you all a Merry Christmas and I hope you all have been given all what you asked for (or what you deserve, whichever is better), and for those who don't, I still wish you a good day!
