- Treat VGA extension name other than "none", "vbe" or "cirrus" as a VGA
compatible device plugin and try to load it.
- Added new plugin type PLUGTYPE_VGA for such a plugins (interally handled like
a core plugin).
- Added panic in devices init for the case no VGA compatible plugin is present.
- Added new method vga_redraw_area() that handles the non-VGA and null size
case. The specific method redraw_area() is called otherwise.
- Moved init_systemtimer() call from extension code to init_standard_vga().
- TODO: Implement VGA subsystem in the Voodoo code to test the new feature.
Voodoo Banshee 2D accelerator code needs to be written to make this really
useful.
latest BIOS images 32-bit and even 64-bit guest OS's are known to boot inside
of Bochs without hacking. This legacy hack could be removed after next release
if nobody complains.
- Using bochsrc option "load32bitOSImage" now causes a warning. It is not
maintained yet, not documented and we don't whether it is used or not.
I guess it was designed to boot a real 32-bit guest OS when the Bochs BIOS
wasn't able to do it.
- Added config option --enable-busmouse to all shortcut scripts. We have two
usable models present now (tested with Win95).
- Added warnings for currently not maintained features in the configure script,
the bochsrc sample and the user doc.
- Removed detection of deprecated bochsrc options "i440fxsupport" and
"vga_update_interval".
- Legacy bochsrc option "user_shortcut" is now deprecated.
- Removed deprecated configure option --enable-misaligned-sse from user doc.
- Updated some TODO items.
external program 'bxhub' (simulating a two port ethernet hub). It is based on
an old SF patch and it has been updated and extended:
- Windows support (tested with MinGW/MSYS and MSVC nmake).
- Command line arguments for 'bxhub' (base port number, MAC address, TFTP).
- Added support for DHCP, TFTP, ARP and ICMP echo (ping). It uses parts of the
code for the 'vnet' module with some additions from the former "slirp backend".
- TODO: code cleanup to reduce duplication, rewrite of the networking plugins
stuff similar to the work done with the sound drivers.
Prepared "biosdetect" option in the harddrv code.
TODO #1: Add support for a comma-separated list of BIOS options.
TODO #2: Implement support for at least "biosdetect=none" in the Bochs BIOS.
configuration, loading images). Cleaned up "romimage" option parsing and
prepared parameter "options" for the behaviour of the Bochs BIOS.
TODO: implement BIOS option "fastboot" to skip the boot menu prompt.
- waveout: added support for RIFF WAVE format and raw output. The formats
'voc' and 'wav' are detected by file extension, raw output is used otherwise.
- midiout: added support for raw midi output (no header, no deltatime).
The 'mid' format is detected by file extension, raw output is used otherwise.
- Added 'midiout' parameter to the global sound option to specify the device
if necessary. The related SB16 parameter now only specifies the output file.
- TODO: Rewrite of the sound configuration and output code to support dual
output (device and file).
implemented important CPU statistics which were used for Bochs CPU model performance analysis.
old statistics code from paging.cc and cpu.cc is replaced with new infrastructure.
In order to enale statitics collection in Bochs CPU:
- Enable statistics @ compilation time in cpu/cpustats.h
- Dump statistics periodically by adding -dumpstats N into Bochs command line
gui init and string paramter handler. The shortcut keys are now stored in an
array of BX_KEY* values in the gui object.
siminterface.h: Fixed some default return values.
- added new symbol BX_WITH_SDL2 and prepared build system
- TODO #1: add new option --with-sdl2 to configure script
- TODO #2: add new file sdl2.cc (porting seems hard to do - writing from scratch
might be better)
- added slirp.conf to NSIS script
- NSIS script now using HTML documentation path from 'install_win32' target
- Makefile: DLX Linux config file renamed to 'bochsrc.bxrc' for win32
- config.cc: bochsrc option removed with coming version
required an external binary and it couldn't be ported to Windows. Now the new
builtin and portable slirp support based on Qemu's implementation is almost
stable and all the 'vnet' DHCP and TFTP features have been ported to the new
slirp module.
TODO: rename all the "slirp_new" stuff to "slirp"
is almost a port of the Qemu 1.1.2 implementation. It has been tested successfully
on Linux and Windows (MinGW/MSYS). The networking module is currently called
"slirp_new", since the "slirp" backend module still exists.
TODO list:
- MSVC support (requires container_of() macro replacement)
- apply fixes and improvements from recent Qemu releases
- use our TFTP implementation to reduce code duplication
- check if we can share ARP and DHCP support with "vnet"
- add SMB support on Linux
- finally remove the slirp backend module support
usb device plugins. Loading the plugin means that the user wants to enable it.
Disabling the device on the command line and in the config interface is still
possible.
- fixed pluginlog init in non-plugin mode
- reduced logprefix length limit and use it for the related string parameter
- increase the device prefix size to 6
- TODO: change some more device prefixes
- If the runtime flag of a bx_list_c object is set, all it's items are set up
as runtime options.
- Set the runtime parameter for all top-level runtime-only lists. Setting up
each single parameter is no longer needed.
- moved some options to the top and some legacy ones to the end of the function
- added some info to the legacy keyboard options
- removed 'text_snapshot_check' keyword
- some coding style changes
- added 'wavein' parameter to specify the wave input device if necessary
- if 'wavein' is not set, Bochs uses the 'waveout' value for input, too
- SB16: the 'wave' parameter is now only used to specify the filename (mode 2 or 3)
- TODO: implement 'wavemode' feature for ES1370 similar to SB16
- added 'sound' option to select the driver and the wave output device
(see bochsrc sample for details)
- the wave device option of sb16 and es1370 is now only used to set up the
wave input device (if necessary)
- cleaned up the speaker code to initialize the 'sound' case correctly
higher resolutions and > 8 bpp graphics modes. The RFB gui with limited
capabilities is still available.
TODO:
- fix random segfaults in dimension_update()
- Windows (MinGW) support
- fixes for clients not supporting 'rfbEncodingNewFBSize'
- fix cursor shape after dimension update()
- after parsing command line only update actions if default has changed
- bx_init_hardware(): extra update of log actions in quick start mode not needed
- isempty() returns 1 if string length is 0 or string has special value "none"
- sprint() copies the formatted / converted string into a buffer
- use new methods in some parts of the code (TODO: win32 dialogs)
- check for the special value "none" to avoid failures
- moved 'user_shortcut' option to the keyboard option
- added new bx_param_c option value BOCHSRC_HIDDEN for parameters that should
only be available in the config interface. The new bochsrc option save and
parser function skip parameters with this flag set. This is useful for
parameters that will be set from the parser in a different way.
- save keyboard bochsrc line using the parameter list directly
- parse keyboard bochsrc options (except 'keymap') using the parameter list
- user shortcut: old-style syntax has already been removed
- increased minimum value for the keyboard's 'serial_delay'
- removed parameter "present" and use the new drive type "none" instead
- re-implemented cdrom media status parameter as a bx_param_enum_c
- TODO: change floppy media status parameter type to be consistent
- fixed bochsrc line after a "raw byte" string parameter
- changed parameter name "macaddr" to "mac" (same as bochsrc option parameter)
- skip disabled parameters when building the bochsrc line
- added "multiline" switch to select the output format (one or multiple lines)
- renamed siminterface method and use it in the network devices code
- renamed config parameter "i440fx_support" to "enabled"
- new config parameter "chipset" added (current choices "i430FX" and "i440FX")
- don't load ACPI support if the i430FX chipset is selected
- select register values for the core PCI devices depending on the chipset
- USB UHCI must be connected to a PCI slot if the i430FX chipset is used
- rombios changes to make the i430FX chipset work
- TODO #1: implement limitation to 1 cpu and 128 MB RAM for the i430FX chipset
- TODO #2: verify register behaviour of both chipsets
fixed enabling of ADX extensions in generic CPUID when enabled through .bochsrc
Small code cleanups on the way to implementation of APIC Registers Virtualization features disclosed in recent Intel SDM rev043
- TODO #1: fix pcipnic / pnic name problem to support direct plugin loading
- TODO #2: automatically assign PCI-only devices to a PCI slot if not already done
- 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.
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.
parsing to the plugin device code
- sb16: modified misc runtime menu creation to make the sb16 parameters optional
- ne2k: changed location of the init() method in file (now matches coding style
of other device plugins)
option parsing to the plugin device code
- added function bx_init_usb_options() to reduce code duplication
- added log function names for 'usb_ohci' and 'usb_uhci'
- documentation updates
the device code. Added panic message to force the user to enable the plugin
with 'plugin_ctrl'.
- moved config parameter creation and bochsrc option parsing for device
'usb_xhci' to the plugin device code
- added minimal documentation for the "log action per device" feature
- added log function name for 'usb_xhci'
