done by the object destructor (changes in cmos, hard drive and keyboard)
- bx_unload_plugins() now deletes the devmodel object in non-plugin mode
- CMOS device now prints the time on exit in human-readable format
- added exit() method to the devmodel object for devices that need to do special
cleanups on exit. Device plugins should call this method from their plugin_fini()
function. If Bochs is compiled without plugin support, for non-core plugins
the exit() method is called directly from bx_unload_plugins().
- exit() method implemented in the keyboard device
- wx "Show Keyboard" feature now only appear when the wxdebug keyboard subtree
is not empty
- cpu cleanup must be done before the devices cleanup
- moved PCI chipset dump call to the devices exit method
* don't initialize cpu specific parameters for the wx debugger if they already
exist
* separate siminterface method init_save_restore() added
* old wx specific handling in quit_sim() removed
* new bx_list_c method clear() deletes all parameters from the list
* moved devices cleanup code from the pc_system to a new devices method exit()
* pc_system init code now sets ticksTotal to 0
* register_state() will be called after init() and registers the device members
required for save/restore
* before_save_state() can do some work before the device state is saved by the
siminterface
* after_restore_state() can do some work after the device state has been
restored (updating dependant stuff)
- for the BrowseDir() function Bochs for win32 needs to be linked with SHELL32.DLL
(currently used for the save/restore support only)
- save/restore support symbol name changed
- log options must be restored after initializing all devices
- menu items and descriptions for save/restore updated
- TODO: implement access to save/restore functions for win32 and wx
- don't load another config file if the restore flag is set
- disabled restore_hardware() for now (will be enabled when save/restore is
complete and stable)
parameters of the wx debugger possible
- started rewrite of shadow parameters and converted keyboard parameter stuff
- test function print_tree() now shows raw byte strings correctly
- removed unnecessary spaces
Averything that required cpu.h include now has it explicitly and there are a lot of files not dependant by CPU at all which will compile a lot faster now ...
- parameter tree structure updated (TODO: should be moved to development.dbk)
- code cleanup: bx_options stuff and obsolete parameter access methods removed
- TODO: rewrite of shadow parameter stuff (for subtree "save_restore")
- siminterface get_param_*() methods num support a base parameter like the generic
get_param() method
- new parameter lists now also have a generated id
- test function print_tree() now handles enum parameters correctly
- proposed parameter tree updated
- boolean parameter type now supports new parameter handling
- new parameter object constructors now supports label initialization
- bx_list_c constructor now supports title initialization
- textconfig: initial support for new parameter handling
- wx: missing CPU config dialog added
- wx: ParamDialog now handles disabled parameters correctly
- removed unnecessary spaces from function calls
* memory parameter handling rewritten (not yet complete)
* new reset() method for bx_list_c for recursive reset of all list members
* memory options in wx now handled in a ParamDialog (ConfigMemoryDialog removed)
* removed obsolete BXP_* constants in siminterface.h
* updated proposed parameter tree
- constant BX_N_OPTRAM_IMAGES for optional RAM images limit added
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
optromimage. You can load up to 4 arbitrary binary images into RAM.
I didn't do any checking on the addresses, so it's up to you to make
sure they don't collide with anything else. Should only be used for
placing files into standard RAM.
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.
- fixed pcidev targets in iodev/Makefile.in
- updated all Makefile dependencies using a default setup (.conf.linux).
TODO: dependencies should be generated at compile time since they depend on
the config settings
- vgaromimage option now compatible with the other rom options. Old style syntax
(without 'file=...") is still supported.
- load order for the rom images fixed (system, vga, other)
- rom images sizes not multiple 512 cause a BX_INFO for now. The original check
will be enabled after updating the vgabios files
- optromimage error messages fixed
- some updates of the bochsrc sample
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.
bochs.h already not include iodev.h which reduces compilation dependences for almost all cpu and fpu files, now cpu files will not be recompiled if iodev includes was changed
- textconfig runtime menu: some options moved to submenu "Misc runtime options"
- bx_param_c: variable group_name and methods set_group() / get_group() added
- bx_list_c: new flag SHOW_GROUP_NAME added (used for SB16 options in runtime menu)
configure script option --enable-magic-breakpoints (enabled by default).
Documented the instruction required to trigger the magic breakpoint
(xchgw %bx,%bx).
single setting without writing the complete line. The sequence of the arguments
doesn't matter now.
- the dmatimer value must be valid to enable the sb16
be used instead of a simple text control (implemented in wx)
- the new flag USE_SPIN_CONTROL is used by the memory size and the irq parameters
- special bx_list_c for the "Other options" menu in the wx configuration added
available at runtime
- wx: 'runtime' flag added to ParamDialog. If this flag is set, all options
with the flag 'runtime_param' clear will be disabled.
- only the runtime options for cdrom's are now enabled in the ATA dialogs at runtime
- the options 'keyboard paste delay', 'mouse' and 'vga update interval' are now
available at runtime
- wxdialog.h: unnecessary comments removed
- new bx_list_c for keyboard options (used in wx, TODO in textconfig)
- new flag USE_BOX_TITLE controls the usage of the list name for the group box label
- wxdialog.cc: unused variable removed
- siminterface: ask_filename() uses the prompt for the parameter name
- wx: missing title of the CMOS dialog added
- floppy path parameter names changed (used by win32config)
- user shortcut parameter description added
- 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
* option "cmosimage" must be saved, too
* most important options (config_interface, display_library, megs, romimage,
vgaromimage, boot) moved to the top of the saved file
- add the "journal" option to the ataX-xxx directive, so the user can
set a specific path for the redolog file (applies only for undoable
and volatile disk modes)
- add the enable handler, so the status and journal options of the ataX-xxx
directive can be hidden even if the ataX-xxx parameter is enabled.
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.

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.
value be the application's directory, no matter where it gets
installed. This is consistent with installing the bioses and
keymaps/* into the same directory as bochs.app.

- for MacOSX/Carbon, if you start the app by double clicking in the finder,
there is no text console. So in logfunctions::fatal(), display the
final message in a Carbon dialog instead of using fprintf.
- in the text-mode config interface, return an error code if the
user tries to use the text menus when there's no text console.
Back in bxmain() this error code causes a panic
"Bochs needed the text console, but it was not usable"
- if a config file was not found, normally we turn off quick start
and drop into the text menus. However in the no-console case the
text menus won't work, so we added a panic: Unable to start Bochs
without a bochsrc.txt and without a text console. This is a much
more useful error than the generic one above.
- removed ensure_text_console() which was making matters worse instead
of better.

completely ignored and Bochs has always been returning 0. Now Bochs should
exit with the proper exit code.
- implementation: BX_EXIT(exitcode) calls SIM->quit_sim(exitcode).
quit_sim stores the exit code in the SIM object, then uses longjmp
to unwind the stack and return to main(). main() calls
SIM->get_exit_code() to retrieve the exit code and returns it.
- If you are wondering why we don't just call exit(exitcode), it is
because in the wxWindows interface all of the CPU simulation runs as one
thread while the user interface runs as another thread. With the longjmp
technique the simulation thread ends cleanly and it is possible to
start a new simulation thread without making a new process.
be used for more things than just the BIOS. Also the keymaps need to
be located relative to the share path, and maybe other things like
graphics and icons, later.
eject, insert, eject, etc. several extra times before allowing you to
actually change the CD. The extra insert/eject cycles were coming from the
param handlers for cdrom status and for the cdrom pathname. To fix this, I
changed wxdialog.cc and textconfig.cc to only call set() on parameters if
they are different from the original value. Now it generally does what you
would expect.
- to change physical CD: change the Bochs CD status to "ejected". On some OSes
that will actually eject it, but on others it will simply close the file so
that the eject button will actually work. Then put the new CD into the
drive, and change the Bochs CD status to "inserted".

This fixes bug #614724: SDL can get stuck in full-screen mode, and provides
a framework for fixing the problem on other full-screen display libraries
such as term, svga, etc.
- add virtual method bx_gui::set_display_mode(mode) which can be overridden
by each display library class, if appropriate. This method is primarily
used when you run Bochs full screen, to tell the gui to switch from full
screen back to a mode where you can use the text console.
- There are two display modes: config and simulation. The mode is changed to
config mode during logfunctions::ask, during the runtime configuration menu,
and before displaying a debugger prompt. It is changed back to simulation
mode whenever instructions are running.
- Instead of being called directly through the global bx_gui pointer, the
bx_gui_c::set_display_mode() method is almost always accessed through
siminterface, like this:
SIM->set_display_mode (DISP_MODE_CONFIG);
SIM->set_display_mode (DISP_MODE_SIM);
Of course siminterface just passes the call on to bx_gui::set_display_mode().
I added it to siminterface so that the config interfaces could call it.
(They don't #include bochs.h so they can't access bx_gui.)
Modified Files:
logio.cc main.cc debug/dbg_main.cc gui/gui.h gui/sdl.cc
gui/siminterface.cc gui/siminterface.h
there is one more option in the configuration file "debugger_log"
if the debugger is compiled in, all debugger output will be also
written to this file. Note: wxWindow config interface is not updated yet
- removed the code for changing the console screen buffer size
- BUG: the gui window receives all keypresses from the console when it gets back
the focus. We have eliminate all keypresses before the simulation continues.

This untested patch shows how and where to call RedirectIOToConsole() when
compiling with SDL on win32. I believe this, or something like it, will
fix the problem of having no console window on SDL.
- enable RedirectIOToConsole() when compiling with SDL on win32, so that
it can be called in main().
- move main() down below the definition of RedirectIOToConsole(), and
add a call to RedirectIOToConsole()
- in WinMain, Bochs always asked the user to press ENTER before exiting.
I moved that code to main() with #ifdef WIN32...#endif around it.
(Maybe this should only be done when Bochs explictly creates a console
window, though.)
- if BXBIOS is not defined, set it to a default value that is produced
in the makefile. This allows us to make disk image TAR packages that
look for the bios images in the $BXBIOS directory. These packages
will be able find the current images for future Bochs versions, without
any modifications.
