- 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'
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.
bochsrc parser. When read it will be possible to define exceptions from the
default setting like this:
debug: action=ignore, pci=report
- TODO (almost everything)
- add a 'name' member to the logfunctions class, since the prefix might be
too short
- apply special log actions the log modules and panic on unknown modules
- support saving special log action to bochsrc
I am merging the code in order to start making shortcuts between VMX emulation and SVM emulation.
Of course SVM emulation is incomplete, completely untested and not expected to work.
But someone could already take a look one the code and give some suggestions.
Also looking for anybody with existing SVM kernels - as simple as possible - for testing.
Status:
- exceptions intercept is not implemented yet
- IO intercept is not implemented yet
- MSR intercept is not implemented yet
- virtual interrupts are not implemented yet
- CPUID is not implemented yet
No advanced SVM featurez planned - I am implementing the very basic 'Pacifica' document from 2005 using QEMU code as reference.
directly while parsing the bochsrc or command line. If plugin support is enabled,
the option could load all optional plugins, not only the ones supported before.
NOTE #1: The old option had all plugins enabled by default and gave the user
a chance to diable them. Now the plugins are only loaded if they
appear in the config line and they are set to "1".
NOTE #2: Loading a plugin that is controlled by a bochsrc option is possible,
but it currently leads to a panic, since the load command is still
present in devices.cc.
NOTE #3: The plugin init code creates the device object and registers the
optional plugin device. As an option, it can create config parameters
and register an option parser. The device init, register state and
reset is still handled in devices.cc, but in the order the devices
have been loaded with the plugin control.
NOTE #4: If plugin support is disabled, the plugin control only accepts the
devices listed in plugin.cc.
- plugin init of core plugins now fails if they are not loaded with the expected
type. For core plugins the load order is important and they cannot be handled
with the chained devices list (used for optional and user plugins).
- some additions for calling config.cc functions from a plugin device
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.
turned off. Removed workaround code from devices.cc.
- removed 'pci_ide' plugin from the optional plugin control, since it depends
on the presence of 'pci' and 'harddrv'.
- define types for plugin init/fini functions
- TODO: add save/restore support, use Bochs function for host to little endian
data conversion, timers of networking modules 'vnet' and 'slirp' should use
the device speed instead of fixed 10 MBit

32-bit CPU using Bochs binary compiled with x86-64 support.
The commit also fixes some init.cc issues with initialization of SYSCALL/SYSRET MSR in AMD hosts and also includes code reorg.
with --enable-avx option. When compiled in, AVX still has to be enabled
using .bochsrc CPUID option. AVX2 FMA instructions still not implemented.
- Added support for Bit Manipulation Instructions (BMI) emulation. The BMI
instructions support can be enabled using .bochsrc CPUID option.
Selecting CPU MODEL from .bochsrc automatically chooses real HW CPUID and also configures Bochs emulator to emulate this specific CPU including all its features only.
Supported CPUs to choose from:
core2_extreme_x9770
corei7_sandy_bridge_2600K
p4_prescott_celeron_336
'vga_update_interval' option. The screen update frequency is still based on
the emulated clock unless the realtime sync is enabled with the 'clock' option.
TODO: rewrite the virt_timer code to support realtime screen updates
independent from 'clock' setting.
- fixed changing parameter 'update_freq' at runtime (timer object and blink counter)
* moved runtime handlers for cdrom from config.cc to the device object
* cd media status variable is now always of type bx_bool
* changed obsolete gui names like "cdromD" to "cdrom1"
* TODO: implement new runtime config mechanism similar to USB
The ACPI support is always automatically compiled in if PCI is compiled in.
The ACPI still could be disabled using .bochsrc 'plugin_ctrl' option.
Updated CHANGES and docs as well.
DAC2 is sent to the lowlevel sound module. DAC1 and sound input (ADC) are not
yet supported. Also unsupported: CODEC (mixer), UART (MIDI) and legacy support.
Sound module selection in configure script now no longer depends on SB16 and
uses autodetection only.
- fixed segfault when saving bochsrc
--enable-vbe is now deprecated and the symbols BX_SUPPORT_VBE and
BX_SUPPORT_PCIVGA have been removed. To enable VBE support, the bochsrc option
"vga: extension=" must be set to "vbe". If PCI is present, you can assign the
"pcivga" device to a PCI slot.
recent version of Slirp with Debian patches applied. On a Linux host the
guest OS can access the internet without running Bochs with root privileges.
TODO:
* rewrite the DHCP part of eth_vnet.cc that it can be used here, too
* Slirp doesn't compile on 64-bit Linux with GCC 4.5
* WIN32 is not supported yet
connected device. For now this feature is only used by the 'disk' device to
specify an alternative redolog filename of some image modes.
- added new methods set_option() and timer() to the base class usb_device_c.
The timer() method is periodicly called from the HC's frame timer code.
- moved runtime device change stuff from the parameter handler to the end of
timer() methods of all hubs. This makes sure that all parameters for the
device have been set at connect time. TODO: this technique could also be used
for the floppy and cdrom media change.
- several fixes related to configurable geometry (some more tests required)
- skip MBR and boot sector image files when reading directory (still unused)
- support overriding cylinder value with 0 in the command line
- don't return failure value when reading unused sectors
- increment buffer pointer when reading more than one sector
- siminterface: added helper method hdimage_get_mode()
- moved hdimage related stuff from harddrv.cc to the hdimage code
- changed hdimage related names
the SF patch #1539417, but rewritten from scratch (patch too old). Differences
to the original version:
* internal parameter name "readonly"
* update parameter if floppy image is readonly
* wxWidgets support
* documentation updates
* no specific toolbar buttons
the default Bochs method using the CTRL key and the middle mouse button there
are now the choices CTRL+F10 (like DOSBox) and CTRL+ALT (like QEMU).
* currently implemented in the X11 and SDL guis only
* TODO: porting to wxWidgets and Win32, documentation updates
