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.
- 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.

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.
- 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.

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.
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).
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- TODO: byte / word wizzling, other color orders, 24 bpp source dithering.
- 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 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.
- Save/restore additions for 2D desktop mode.
- Fixed pitch in 3D overlay mode for hardware cursor.
- TODO list:
- Minor issues in explorer navigation bar of Win98SE.

- Serious display issues in 16 bpp modes of XP guest (Voodoo3 only).
- 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.
to 11. Accessing 'extension' data using 'name' index is illegal and at least
gcc version 7.5.0 has produced incorrect code for creating short file name.
The 'vnet' networking module now uses 192.168.10.3 and bxhub is setting up the
slirp compatible IP 10.0.2.4 for additional services. Added host name "vnet-ftp"
in the DNS code to translate it to the new IP address.
- FTP: handle the hidden flag on Windows the same way as on other platforms.
- TCP/IP: fixed some gcc 9 warnings (checked with Cygwin gcc 9.3).

- bxhub fix: send all pending packets one after the other.
- TCP fix: when connecting, return default MSS option value 1460.
- TCP fix: handle the case when FIN is set in final data packet.
for the whole file, now the buffer has maximum TCP window size and the file is
read on demand. The directory list is now written to a temporary file that can
be sent with the new code.
- Skip special TELNET sequence required for transfer abort to make it work.
- On FTP quit, unregister data port and free data buffer if necessary.
- Some other small FTP code cleanups.
