- CPU code refactor, remove uses of bx_bool datatype and use C++ classic bool instead.
This enable better compiler optimizations and reduce binary size
- Changing VGA extension to "voodoo" did not work in the config interface.
Moved plugin loading to the string parameter handler and added plugin
unloading case.
- Unloading "voodoo" VGA plugin resets pluginVgaDevice to stubVga.
- pluginUnregisterDeviceDevmodel() now supports core plugins.
- Some other small plugin related changes.
- Moved wx gui plugin entry point to wx.cc, so we can use the macro
PLUGIN_ENTRY_FOR_GUI_MODULE to be compatible with the other guis.
- Updated gui Makefile dependencies.
- Improved macro definitions for plugin entry points.
- Forward declarations of plugin entry points are only required when plugin
support is off.
- Improved panic message for the case when plugin entry point is not found.
loaded in bochsrc with "plugin_ctrl" or with their own name, the user plugin
option and the special cases for PLUGTYPE_USER are no longer needed. Updated
example patch to make it work with the latest SVN code.
plugin_entry(). The additional boolean argument "init" is used to select the
requested action. The entry points still have unique names for compatibility
with the "non-plugin" compilation. Added macros for setting up these names
(e.g. PLUGIN_ENTRY_FOR_MODULE for device plugins).
- Now that we know about all available plugins at startup, the bx_list_c object
"plugin_ctrl" contains a fixed number of bx_param_bool_c objects representing
the requested status (1 = load). It is verified at simulation startup.
- The config interface creates two text lists (textconfig) or list boxes (win32,
wx) from it to show the remaining available and the loaded plugins. Loading
and unloading is performed immediately and plugins may install / uninstall
options in other menus / dialogs.
- Modified the "non-plugin" code to make the optional plugin control work very
similar in this mode.
- bx_load_plugin() now returns the status of the operation.
- Plugin load failures are now correctly handled by the plugin code (unloading
if necessary, then panic).
- In case of cross compiling of the win32 gui, use the environment variable
WINDRES for the name of the resource compiler.
- Added example shortcut script for cross compiling on Linux for Windows.
- The selected / detected disk image mode is now stored as a string constant to
simplify code (same as Bochs core).
- Changed command line option to select operation mode to "-func=X" to avoid
confusion with disk image mode.
- Documentation updates.
- In plugin mode make sure all hdimage plugins are loaded for mode detection.
- Implemented image mode detection via hdimage_locator_c.
- TODO: use the new code for bximage, too.
- Added support for loading all plugins of one type using wildcard "*".
- Unloading no longer removes the plugin object. Now the member "loaded" is
set to 0 and the type of a device plugin is reset.
- Added plugin_cleanup() function to remove plugin objects on Bochs exit.
- Some other related cleanups in the plugins code.
implementing disk image support with an external C++ class. With the new code
it's now easier to implement support for additional disk images formats, so we
don't need the old stub anymore.
string constants instead of hardcoded values. Available modes are detected at
Bochs startup and stored in a string array before initializing options. In the
plugins case additional modes are read from the plugins list. If plugins are
off, the hdimage_locator_c registry is used. Related changes in all parts of
Bochs that need the hdimage stuff.
TODO #1: Network and sound drivers could be handled in a similar way.
TODO #2: Make disk image mode detection work again in plugins mode.
- Added suffix "_gui" to the base name of display library plugins.
- Added new function plugins_search() that browses the plugin folder(s) and
detects the type from the library name. Plugins with no prefix or suffix are
treated as i/o device plugins. The plugin_load() function uses this database.
- Some related fixes and cleanups.
- Renamed vpc-img.* files to vpc.* and removed hack for image mode name conversion.
- Added suffix "_img" to all disk image mode plugin base names. This is important
for the future implementation of a plugin enumeration at Bochs startup.
- Common hdimage code, lowlevel cdrom code and the classes for the Bochs "own"
image modes (e.g. flat, sparse, growing") are now a part of the Bochs core.
- All classes for image modes present in separate files are now built as
plugins with the same self register mechanism as network, sound and usb
modules. Defined new plugin type PLUGTYPE_HDIMAGE.
- Temporarily disabled the base image format detection of the undoable/volatile
modes for the "external" modes in the plugins case.
- TODO: Bochs should know about all of the available plugins and their
capabilities right after startup, but before the configuration stage.
- Added buffer for maximum 16 key events.
- PS/2 keyboard now sets the changed indicators only.
- Added support for the yellow status indicator in the win32 gui.
- Added HID code for the menu key.
- Added support for the yellow status indicator in the rfb and vncsrv guis.
- Cleaned up status indicator code in SDL, SDL2 and X guis.
- Unified USB keyboard and keypad code. Removed the keypad lookup table.
- Moved keyboard indicator stuff to the devices code and use it for both the
USB and legacy keyboard device. In the USB case a different color is used.
- In the SDL, SDL2 and X guis added new status indicator color yellow. It is
designed to be used by the USB keyboard (write flag 1 and "auto_off" flag 0).
- Added missing sysmbol to the German X11 keymap table.
TODO #1; Add some missing HID key codes.
TODO #2: Add key event queue to avoid losing events.
TODO #3: Unify keyboard and keypad code.
TODO #4: Support multiple non-modifier keys pressed at the same time.
TODO #5: Share keyboard indicators with the legacy PS/2 keyboard.
- Added NUMLOCK to the table of supported keys.
- Temporarily added status bar item for the keypad NUMLOCK indicator.
- TODO: Add new HID device "keyboard" with all keys supported.
- Added new devices method register_default_keyboard() and handle keyboard
events similar to the mouse stuff.
- Prepared removable keyboard support for the "paste bytes" feature.
- Store keyboard type in device object to avoid reading parameter at runtime.
- Related code cleanups.
- TODO #1: Extend USB keypad to full featured keyboard.
- TODO #2: Paste bytes support for USB keyboard.
- Always apply the A20 setting to the requested address.
- Fixed the conditions for SMRAM access.
- Added support for memory handlers and removed direct VGA memory access.
- Added support for reading from BIOS flash memory.
It creates an array of strings from a string containing a comma separated list
of options. Now using this function for display library options, USB port
options and ROM image options.
is mapped to device number #2, but for the i440BX chipset we are using #8
(expected by real BIOS when testing and some timer later added support for it
in Bochs BIOS).
The latest release is from 2001 and it will not work on modern Linux systems.
Parts of the SVGALib code have been moved to the Linux kernel and the X11 and
SDL libraries are using it as a video driver.
- Now cursor can appear in two different modes (if supported by terminal)
- Simplified text cursor handling.
- Show a status bar if terminal has enough lines for it. Added "show IPS" output
there unless display library option "hideIPS" is used.
- Reading data register without result present returns the last byte of the
previous result and enters result phase just like an invalid command.
- Changed name of bit #7 of MSR to RQM (from spec) and some small cleanups.
- The X gui behaviour should be unchanged.
- RFB / vncsrv: cursor shape fixes.
- Changed format of the font parameters to fix "double width" characters.
- Restore guest charmap after leaving gui console.
- Now using text_update_common() for the new text update API in addition to the
graphical text snapshot feature.
- Drawing to snapshot buffer moved to new method draw_char_common().
- A gui using the new text update API only needs to implement the new method
draw_char(). The method set_font() is optional and it can be used to update
font bitmaps / pixmaps.
- Modified the RFB gui to use the new API. Now the VGA features split screen
and h/v pel panning are supported by the RFB gui. The legacy text_update()
method is now empty but it must be present for compatiblity.
- TODO: Implement new API in some other guis to reduce code duplication.
the flashrom project a JEDEC chip needs to be emulated here. Tests with BIOS
images designed for the i440FX chipset are okay, but for the i440BX chipset
some more commands need to implemented.
- Store BIOS ROM start address and use it instead of hardcoded BIOS_MASK.
- Added stub for BIOS ROM access switches.
- Verify checksum of legacy Bochs BIOS, too.
selected PCI chipset. When testing Bochs with a real BIOS image the programming
sequence for the ESCD unexpectedly overwrites some BIOS locations and it fails
to reboot. For the i440BX AGP chipset development it is required to test with
a real BIOS image, but currently reporting "unknown flash type". For now I have
added two stubs with unmodified behaviour.
- Access to VGA registers via Banshee address space is not memory mapped.
- Added BX_ERRORs for unimplemented unaligned access to i/o registers.
- Access to the unimplemented YUV address space now causes BX_ERROR.
- Removed some TODO comments.
