- Removed "pseudo device plugin" containing common code and all connectable
USB devices.
- Moved USB device base class and module handling to the Bochs core.
Now loading USB device plugins in usb_common.cc.
- Created separate plugins for each USB device implementation.
- Modified Bochs plugin system to support new plugin type PLUGTYPE_USBDEV.
- Added entries for the non-plugin case similar to the network and sound stuff.
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.
- Changed the name of the entry point of the gui plugin code to
lib{gui_name}_gui_plugin_init(). It is used when loading plugin with the new
type. Added gui init code for the non-plugin version in plugin.cc.
- Some related changes for the "wx" case.
- The function load_and_init_display_lib() now only returns 1 on success.
- Minor other changes.
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.
almost implemented, the port owner handling and the UHCI companion controllers
are present. High speed devices are not yet supported, since the EHCI scheduler
code has not been written yet (e.g. porting from Qemu). Low and full speed
devices should be detected correctly and work after port ownership change to
UHCI. 6 ports are available and the bochsrc syntax is similar to other HCs.
with devices conected at runtime.
- Added restore handler support for the bx_list_c class. If a handler is
registered, it will be called after restoring all of the list's members.
- USB hub: add special lists to the port state and add pointers to the
runtime-only options for each port. The restore handler of this list calls
init_device() to make sure all connected devices can be restored.
- Call restore_logopts() after restoring hardware to make sure all saved
modules have been created.
- TODO: the USB cdrom also needs a fix for it's runtime-only options.
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
- 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)
- in wx we had two logfunctions for the siminterface (removed duplicate init)
- renamed siminterface prefix to "SIM"
- moved variable "pluginlog" to the plugin interface
- fixed / removed some forward declarations
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()
- bx_list_c: added support for removing parameter with other parent list
- USB HC's: remove item from runtime config on simulation exit
- initialize bx_user_quit in bx_begin_simulation()
- only remove optional plugin from list if alrady unloaded
- 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
- 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
is based on a patch originally designed for DOSBox. Currently only the Voodoo1
adapter model can be emulation. The emulation is currently slow, but we intend
to clean up and optimize the code. Running the 3D engine in a separate thread
is also planned. To compile with Voodoo support the configure option
"--enable-voodoo" must be used. Then the device can be activated with
"plugin_ctrl: voodoo=1" in bochsrc or on the command line. The device will be
assigned automatically to a PCI slot unless you do that manually. A specific bochsrc
option to select the adapter model will be added when the code has support for it.
- re-implemented siminterface method is_wx_selected() (the old one had been
renamed to has_debug_gui() which is something different now)
- don't use alarm() if the wx gui is selected and instead use the wxTimer based
code that already exists for wxMSW
and devices. This option can be used by external bochsrc creation tools to
offer config related to the emulated hardware only (fixes SF item #1251456).
- TODO: add available display libraries.
- 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.
on Windows. Added early command line check for this option to call the
console creation for sdl and wx only if required. NOTE: The console is still
needed for the config interface 'textconfig', the console debugger and log
output to stdout/stderr.
also works and no deplist trick is required
- bx_param_c destructor now deletes the dependent list if it exists (memory leak)
- bx_list_c::clear() only deletes the parameter if the list is it's parent
- added new method cleanup_save_restore() to free memory on simulator shutdown
- unknown module names now cause a panic
- added log function names to some more devices
- TODO: find a way to configure log actions by device in the config interface
start menu (most of the devices do not exist at this point)
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.
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.
