hardcoded one. In plugins mode now all plugins with PLUGTYPE_GUI can be used.
Added similar code for the case plugins are disabled. The macros
PLUG_get_plugins_count() and PLUG_get_plugin_name() can be used in both cases.
- BXRS_PARAM_BOOL macro should be used for bool type members only.
- Fixed usage of wrong BXRS macro for numeric member in usb_hid.cc.
- New PCI parameter "advopts" must be saved in config.
- FIXME: Bochs hangs at startup in restore mode.
- Added special mode to all plugin entry functions that returns the plugin type.
- The plugins search function now temporarily loads all available plugins and
reads the plugin type using the new mode PLUGIN_PROBE.
- Added "loadtype" to the plugin structure to store the type used for plugin
loading (currently only the voodoo plugin provides two types).
module code. Sound driver names are now stored as string constants instead
of hardcoded values. Available modules are detected at Bochs startup and stored
in a string array before initializing options. In the plugins case available
modules are read from the plugins list. If plugins are off, the registry of
bx_sound_lowlevel_c is used. Related changes similar to the hdimage and
network modifications.

hardcoded values. Available modules are detected at Bochs startup and stored in
a string array before initializing options. In the plugins case available
modules are read from the plugins list. If plugins are off, the eth_locator_c
registry is used. Related changes in all parts of Bochs that need the
networking stuff.
TODO #1: Sound drivers could be handled in a similar way.
- bx_shadow_bool_c: removed unused bitnum feature and changed data type.
- Changed return type of memory handlers to bool.
- Modified virtual timer, PIC and PIT code.
* extract logfunctions class definition to separate include logio.h to simplify the bochs.h reading
next step: try to minimize amount of includes in bochs.h as everyone in Bochs includes it
for example it includes pc_system.h which is not necessary required to be included in all CPU source files
- 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.

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.

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.
- Shortcut parser sets a flag in case of error.
- String parameter handler resets to old value if the new one is invalid.
- User button handler shows a message box if the parser signals an error.
- Added support for split screen mode and horizontal pel panning.
- Text mode cursor now correctly visible independent from blink state.
- Workarounds for the existing text_update() API.
set accordingly.
TODO #1: Text mode features split screen and h/v pel panning missing for now.
TODO #2: Show error messages related to dialogs in message boxes.
- New attempt to fix the host-to-screen bitblt issue with monochrome source.
The specs are wrong at this point. The rules for calculating the real source
pitch are still unknown. These hacks should fix most the glitches.
- Added source colorkeying support for host-to-screen blt with pattern.
- Disable i/o and memory access in PCI command register before probing and
setting up base addresses and re-enable it when complete for selected device.
- Legacy BIOS should not enable busmaster function in PCI init.
- Banshee: Added colorkey support for host-to-screen blts without pattern.
- Clearing base address registers in reset is not okay. Maybe we have to
unregister i/o and memory regions here. This affects other devices, too.
- Some other small changes and typo fixes.
- Added support for "byte packed" monochrome source data.
- TODO #1: All modes except 16 bpp color source untested (based on specs).
- TODO #2: byte / word wizzling, other color orders, 24 bpp source dithering.
- Added support for undithered 24 bpp source data.
- Fixed "standard monochrome" mode in case of transparency.

- Implemented screen-to-screen blt function (untested).
- Fixed and improved "Rectangle fill" function.
- "SGRAM fill" function rewritten similar to the other functions.
- TODO: cpu-to-screen function (handle data written to bltData register).
- Implemented destination colorkey support for the remaining functions.
- Some other small changes in the Banshee code.
- TODO: Source colorkey support for host-to-screen blts.
- Fixed SGRAM fill command (y start and size have one more bit - spec is wrong).
- CMDFIFO packet type #5: texture address is a 32 bit register number.
- Setting clut_dirty is required when writing to most of the fbiInit registers.
- Added colorkey support for screen-to-screen pattern blt, rectangle fill and
pattern fill commands.
- Consider colorkeying enabled when branching to normal or pattern blt functions.
- Changed 2D TODO messages to BX_ERROR and some other minor changes.
feature of packet type #5. Added some W2 cases for texture writes, modified
code for linear LFB writes and added BX_ERROR messages for the WN cases. Some
more test cases are needed for a complete implementation.
- Real fix for the Voodoo2 DirectX issue after CLUT pens implementation.
- Banshee hardware cursor now uses the CLUT pens for the background.
- Banshee hardware cursor now uses the same 3D start address as update().
- Set clut_dirty flag when writing to fbiInit registers. This fixes a Voodoo2
issue when using the DirectX driver.
- Report another unimplemented case in the texture code.
video refresh in 16 bpp modes. The Banshee also uses this feature in 16 bpp
desktop mode in addition to 3D modes. The code for the pen calculation comes
from the original Voodoo patch for DOSBox. Since it was unused there, I had
disabled it when porting to Bochs.
- Fixed serious issues in 16 bpp mode of XP guest (clipped y value).
- Added BX_ERROR messages for unsupported features.
- Added / updated comments.
- TODO #1: Background pattern issues in XP guest still remain in all modes.
- TODO #2: Some small issues in Win9x guests caused by monochrome host blts.
- Removed SDL specific code to reduce dependencies. SDL works okay with
pthreads or win32 implementations.
- Prepared semaphore support for the use in the Voodoo code (thanks to Luigi B.).
- Polygon fill: Check if pixels are within clip window.
- Polygon fill: Added error message for unimplemented pattern ROPs.
- Some cleanups in the code for pattern ROPs with transparency.
- Added options "net" for the IP address space and "ftp" for the FTP server.
- Added some sanity checks for the IP address configuration.
- Added sample config file.
- Added new config file options "host", "dns" and "dhcpstart" (similar to slirp).
- modified bx_vnet_pktmover_c class to be compatible with other modules.
- On TFTP RRQ check file presence directly (fixes iPXE boot).
- Fixed start address for the gui screen update in 3D overlay mode.
- Small optimization for drawing transparent monochrome bitmaps.
- In the restore case start the fifo thread in after_restore_state().
- Report unimplemented colorkey feature (test case missing).
- TODO: issues in some Windows guests still not fixed.

- Moved server ID and lease time options to the top of the DHCP reply.
- Increase TFTP buffer size as expected by iPXE.
- TODO: The vnet module still has boot file name hardcoded.
- Enter command mode with F7 key only, but no modifier pressed.
- Pressing / releasing modifier key only doesn't leave command mode.
- Changed some headerbar button access keys using modifiers (e.g. shift + c
calls config button handler). See user doc for all supported keys.
with keypress combination. This feature is currently supported by the x and
sdl2 guis only and it can be activated with the "cmdmode" (command mode)
display library option. If enabled, pressing the F7 key enters this mode (shown
in the leftmost statusbar item) and the next keypress (except F7) is not sent
to the emmulated keyboard. If the key is supported, the associated action is
performed. Both x and sdl2 support calling the handlers of 8 headerbar buttons.
The sdl2 gui additionaly supports toggling fullscreen / windowed mode.
Supported keys:
c - Press the Copy button
e - Press the Config button
f - Toggle fullscreen mode (sdl2 only)
n - Press the Snapshot button
o - Press the Power button
p - Press the Paste button
r - Press the Reset button
s - Press the Suspend button
u - Press the User button
F7 - Send F7 keypress to emulation
TODO: add support for other guis.
Moved status bar update to the gui thread and added a new event type called
BX_ASYNC_EVT_STATUSBAR to invoke it. Changed size and style of the status bar
items.
- moved code that sends the framebuffer update to the flush() method.
- method clear_screen() now sets up an update region to work as expected.
- fixed and improved function rfbAddUpdateRegion().
- added new function rfbSetUpdateRegion() to simplify code.
