Stanislav Shwartsman
-------------------------------------------------------------------------
Changes in 2.3.7 (June 3, 2008):
Brief summary :
+ More optimizations in CPU code - Bochs 2.3.7 is more than 2x faster
than Bochs 2.3.5 build !
- Implemented LBA48 support in BIOS
- Added memory access tracing for Bochs internal debugger
- Implemented Intel(R) XSAVE/XRSTOR and AES instruction set extensions
- Many fixes in CPU emulation and internal debugger
- MenuetOS64 floppy images booting perfect again !
- updated LGPL'd VGABIOS to version 0.6b
Detailed change log :
- CPU
- Support of XSAVE/XRSTOR CPU extensions, to enable configure with
--enable-xsave option
- Support of AES CPU extensions, to enable configure with
--enable-aes option
- Fixed Bochs failure on RISC host machines with BxRepeatSpeedups
optimization enabled
- Implemented SYSENTER/SYSEXIT instructions in long mode
- More than 100 bugfixes in CPU emulation correctness (both x86 and x86-64)
- MenuetOS64 floppy images booting perfect again !
- Updated CPU instrumentation callbacks
- Bochs Internal Debugger and Disassembler
- Added memory access tracing for Bochs internal debugger, enable
by typing 'trace-mem on' in debugger command line
- Many bug fixes in Bochs internal debugger and disassembler
- System BIOS (Volker)
- Implemented LBA48 support
- Added generation of SSDT ACPI table that contains definitions
for available processors
- Added RTC device to ACPI DSDT table
- Added implementation of SMBIOS
- I/O devices (Volker)
- VGA
- Implemented screen disable bit in sequencer register #1
- Implemented text mode cursor blinking
- Serial
- new serial modes 'pipe-server' and 'pipe-client' for win32
- new serial mode 'socket-server'
- Configure and compile
- Fixed configure bug with enabling of POPCNT instruction, POPCNT
instruction should be enabled by default when SSE4.2 is enabled.
- Removed --enable-magic-breakpoint configure option. The option is
automatically enabled if Bochs internal debugger is compiled in.
It is still possible to turn on/off the feature through .bochsrc.
- Allow boot from network option in .bochsrc
- Added Bochs version info for Win32
- Display libraries
