- SIM->opt_plugin_ctrl() now can be used to verify the optional plugin
configuration when using the plugin name "*". The 'load' value 1 makes
sure that all plugins with the value 1 are loaded. The 'load' value 0
unloads all plugin with the value 0 (marked for removal).
- add the default set of plugins to the 'plugin_ctrl' list and load all these
pre-defined optional plugins before parsing the configuration.
- special wx case: verify plugin configuration before showing the plugin
control dialog and before initialising hardware.
- device plugins that have been loaded, but not configured now set their
plugin control value to 0. Added the plugin unload check before signalling reset.
- enh_dbg: fixed defined-but-not-used warnings
- siminterface: renamed 'wx_debug_gui' to 'bx_debug_gui' and updated comments
- TODO: remove the wx debugger and use the enhanced gui debugger instead
in the config interface. Applied settings are marked as 'done' with the value
-1 to avoid unwanted modification. NOTE: Not all Bochs modules exist when
running the start menu / dialog.
- siminterface: don't create plugin parameter if it already exists
- wx: make sure all plugins are loaded when creating plugin control dialog
- USB HC's: fixed removal of parameters when unloading plugin
also works and no deplist trick is required
- bx_param_c destructor now deletes the dependent list if it exists (memory leak)
- bx_list_c::clear() only deletes the parameter if the list is it's parent
- added new method cleanup_save_restore() to free memory on simulator shutdown
- unknown module names now cause a panic
- added log function names to some more devices
- TODO: find a way to configure log actions by device in the config interface
start menu (most of the devices do not exist at this point)
invalid module names, save log actions to bochsrc)
- added new member 'name' to the logfunctions class for the case the prefix
is too short. Added to some devices with longer names.
plugins is implemented in bochsrc, these functions can be used to install
additional options from the devices code. Then the whole init / parse / save
code for this device can be moved from config.cc to the device plugin.
with the host time. After using a runtime config dialog or save and restore
simulation, this behaviour makes the PIT clock and the VGA update timer
running way too fast until it's back in sync. Now the elapsed time is stored
in the variable 'real_time_delay' and it is used to let the PIT clock run at
realtime speed, even if it is out of sync.
- fixed size entries in bitmap file header for 8 bpp
- bx_param_filename_c now uses the file extension from the initial value as
the default (if present)
- SIM->ask_filename() now uses the correct parameter type
- win32paramdlg AskFilename(): added filter for BMP files
parameters (path + status) have been set. TODO: implement this feature for the floppy, too.
- call update_drive_status_buttons() from update_runtime_options() to reduce the number of calls.
Now call update_runtime_options() from the gui floppy / cdrom handlers after closing dialog.
The patch was posted in mailing list at Thu 6/16/2011.
Desription for CHANGES:
- Memory
- Added new configure option which enables RAM file backing for large guest
memory with a smaller amount host memory, without causing a panic when
host memory is exhausted (patch by Gary Cameron). To enable configure with
--enable-large-ramfile option.
each other. Devices can register a handler to update it's state after runtime
configuration. The new method update_runtime_options() executes all registered
device handlers before the simulation continues.
- USB host controllers now using the new mechanism to handle the runtime device
change (replaces the previous timer-based implementation). TODO: floppy and
cdrom could use this feature, too)
- improved USB device change messages
* ported the read part of the Qemu vvfat block driver
* added win32 specific directory functions (required for MSVC)

dependency list processing, enum parameter support)
- bx_param_enum_c: added argument for the default value of the dependent bitmaps
to set_dependent_list()
- bx_param_num_c: dependent_list is now a protected member of the object to make
it accessible for the enum specific dependency code
- config.cc: ata parameter dependency rewrite to avoid multiple dependencies
- config.cc: added missing dependency for SB16 parameter list
Bit64u value with the "enable bitmap" (e. g. bit #0 is the enable value for
the first item of the dependent list). TODO: use this feature in win32 and wx
dialogs
- ata drive type and loader hack parameters now using the enum dependent list
- avoid multiple dependencies in the SB16 config menu
- added file extension support for bx_param_filname_c
- fixed showing of tab control child lists
- added special disk menu for the win32 ParamDialog
- on win32 use the ParamDialog instead of textconfig submenus (TODO: gui dialog
replacement for the start menus
- Added configure option to compile in GUI frontend for Bochs internal
debugger, to enable configure with --enable-debugger-gui option. The GUI
debugger frontend is enabled by default with Bochs internal debugger.
If needed to compile without GUI debugger (in case of compilation issues) use --disable-debugger-gui
* initialize plugin system before parsing bochsrc and command line
* pass previous value to bx_param_string_c handler

for trailing null byte when using strncpy)
* length of initial string should not be larger than maxsize
* reset() method now uses set(initial_val)
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
- new display library option "windebug" enables the new feature
- simple dialog box with a command line and a multiline text viever
- TODO: implement modeless dialog with cpu registers and it should be possible
to interrupt "continue" and "step N" commands

* 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
* changed data format of text files for save/restore (looks like C/C++ structures,
similar to the format used in old save/restore branches)
* don't set the initial value of shadow bool parameters
* don't set the initial value of bool parameters twice
* cpu/init.cc: missing #undef added
* ne2k.cc: variable tx_timer_active was never set to 1 (type now bx_bool)

* pic.h: type of member 'byte_expected' changed to Bit8u
* pit_wrap.h: unused members removed
* fixed minimum limit of signed variable types

The text format hex number is now initialized in the constructor
* added missing newline after filename for binary data
* fixed data size of 64-bit shadow parameters
* fixed save/restore output format of numeric parameters (signed/unsigned/64-bit)
* cpu/init.cc: fixed macro name and added missing #undef line
* 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)
* new parameter object type bx_shadow_data_c for binary arrays (e.g. system
and video memory, CMOS RAM, PCI config space)
* save_state() completed and restore_hardware() implemented
* get_sr_root() returns the list with the save/restore subtree
- for the BrowseDir() function Bochs for win32 needs to be linked with SHELL32.DLL
(currently used for the save/restore support only)
