Make save/restore default feature, the configure option for save/restore removed from configure script and save/restore made available forever. All code now assume it is exists. Bochs save/restore tree previosly called "save_restore" renamed to "bochs" tree and it will be havily used everywhere, starting from save/restore and ending by various bochs debugger functions. I am going to rework debugger code to get rid of debug CPU access functions and use this "bochs" param tree instead
build script
- added --enable-new-pit to the deprecated section of the configure script
- show DEPRECATED messages in configure script in uppercase letters (most of
them should be removed before the next major release)
* removed old-style mouse stuff
* TODO: implement USB tablet from Qemu and re-implement Bochs USB keypad
- clear out USB hub structures in constructor to avoid segfault
- keyboard: mouse capture flag must affect all mouse types
* partial rewrite of the USB device emulation code (TODO: mouse and keypad)
* configure.in and iodev makefile updates
* removed old-style data structure for the USB harddisk
* TODO: save/restore support for removable devices
- PCI USB destructor now resets all runtime parameter handlers
- set log prefix for the SCSI device
- fixed a warning in the SCSI emulation code
Enable disasm by default - in adds some useful information to debug messages in log file
Remove defines for 8bit registers from cpu.h, the x86 arch defines not match defines used by set_reg and get_reg methods.
The Bochs anyway even doesn't compile if cosimulation configured enabled.
But in the same time the cosimulation code only disturbs to the future development of Bochs debugger, for example adding x86-64 functionality ...
For those of you who still may want to see the cosimulation code inside I put it in patch and upload it Bochs CVS patches folder. Read comments for the patch ! ----------------------------------------------------------------------
Change BxSupportPAE and BxSupportGlobalPages macros to Bochs style names
Set bx_cpu_id in BX_CPU_C constructor (safe way)
Backup cpu-level check for paging features at compile time (already checked in configure)
Some warnings and indent fixes
speed up get_segment_base method for x86-64 case
present and a quickstart option exists, too
- improved check for GTK 2.x (only needed if basename of wx is 'wx_gtk2')
- moved/added some deprecated configure options to the end of the script. These
checks should force users and distrubutors to update their config options.
* added hack to detect GTK 2 and set include path
* don't use obsolete wxNotebookSizer
* TODO: wxGTK version is still buggy (wrong dialogs when pressing toolbar buttons)
- updated version number and strings
* SSE/SSE2 need CPU level 6
* external debuggger supported on win32 only
* docbook2html needed for building Docbook documentation
- missing result value for 3DNow! support added
- OSX sound support is used for MacOS 9, too
- changes to the original svga_cirrus patch:
* PCI memory/mmio PnP support, some emulation and compile fixes
* ported write mode 4 + 5 and some bufixes from cirrus vga in qemu
* new graphics API, hardware cursor support, configure option added (Robin Kay)
* partial support for transparent bitblt and bitblt write mask
2. Fixed bug
[ 989478 ] I-Cache and undefined Instruktions
The L4 microkernel uses an undefined instruction to
trap for a special requests into the kernel (LOCK NOP).
The handler fixes this up and gives the user a special
code page with syscall stubs. If you're not using the
I-Cache optimization everthing works find on bochs. But
if you enable the I-Cache (--enable-icache), then the
undefined opcode exception is thrown only once for ever
virtual address it occurs. See the demodisk of the
L4KA::pistachio
(http://www.l4ka.org/projects/pistachio/download.php).
In this case the pingpong benchmark of this demo is of
interest. Everything runs fine until the program tries
to spawn a new task for its measurements. This new task
shares the code of the creating program. But the new
task stops executing at the undefined instruction
explained above and no exception is thrown.
configure script option --enable-magic-breakpoints (enabled by default).
Documented the instruction required to trigger the magic breakpoint
(xchgw %bx,%bx).
- pit: and time0: options are still supported but deprecated
- warn when parsing deprecated directives
- fix wrong number of ata_device_translation_names
- still to do:
- setting time0 to utc is not yet supported
- the man page, user guide and .bochsrc still need to be updated
with the new options
* configure.in: readline check is only necessary if the debugger is enabled
(patch from Jeroen Janssen)
* iodev/Makefile.in: dependencies updated after adding gameport device
* support for different resource compilers added (rc / windres)
* bochs must be linked with advapi.lib for registry access
* optimization flag changed to /Ox
* symbols BX_HAVE_MKSTEMP, BX_HAVE_SYS_MMAN_H and HAVE_ETHERTAP must be set to 0
* BX_HAVE_REALTIME_USEC definition fixed for MSVC
* vmware3.h: definition of COW_Header fixed for MSVC
These changes are based on the SF patch #742670. It did not work with
plugins disabled.
Here is the descriiption of patch #742670:
the library dependencies (see objdump -p file) in the
main bochs binary and the gui plugins are wrong:
- the gui plugins don't depend on their respective gui
libraries
- the main bochs binary depends on all the gui libraries
this doesn't seem much of a problem, since the needed
libraries are loaded anyway, but it's problematic when
building packages for binary distribution of bochs.
in Debian, the package building tools will set package
dependencies according to the library dependencies of
each file, so the result is:
- the main bochs package depends on all libraries. this
includes libwx, libsdl, libncurses and xlibs.
- the indivudual plugin packages don't depend on any
gui library
so when a user wants to run bochs with the curses gui
and installs the bochs-curses package, he/she will be
forced to install Xfree86, WxWindows and GTK+ on
his/her system.
the attached patch fixes the problem by moving the
linker flags related to GUI libraries to the right
makefile (gui/Makefile.in)
You can now choose for each disk on the ata interfaces the
disk mode, between :
- flat : one file flat layout
- concat : multiple files layout
- external : developer's specific, through a C++ class
- dll : developer's specific, through a DLL
- sparse : stackable, commitable, rollbackable
- vmware3 : vmware3 disk support
- undoable : flat file with commitable redolog
- growable : growing file
- volatile : flat file with volatile redolog
- z-undoable : gziped flat file with commitable redolog
- z-volatile : gziped flat file with volatile redolog
A new "bxcommit" utility can merge commitable redologs to
flat images.
- it works only on x86 with gcc2.95+
- uses the GCC function atribute "regparm(n)" to declare that certain
functions use the register calling convention
- performance improvement is about 6%

Comment from the author:
Attached is a "patch" file detailing what you need to do
to add USB support (UHCI only for now) to your existing
Bochs (2.0.xx) source code.
I use Win32 and VC++ but the source and modifications
should be platform and compiler independant.
Please let me know if this patch some how breaks the
build process of your compilation (Bochs 2.0.0 or above
only).
I would also like any feedback on how this code works
(or doesn't work) on your platform and within your
images. If you explain in as much detail as you can on
how it did or did not work, I will try to add to the source
to help it work on all platforms and images.
