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).
- 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.
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 case for "*-msys" to the existing "*.mingw*" cases.
- Fixed $JADE value in case the program is not installed.
- Fixed RedirectIOToConsole() function for MSYS with 64-bit gcc 9.2.
- Don't set up and load pre-defined optional plugins in restore mode.
- Remove the save/restore registration in Voodoo destructors.
- TODO: Fix frozen SDL/SDL2 display after restore.
- Get rid of VER_STRING since it's the same as VERSION
- Add new defines VER_MAJOR, VER_MINOR, VER_PATCH and VER_SVN and use them for
the version number on Windows.
- TODO: Add the capability to detect installed version to the Windows installer.
use new method do dump param tree during save/restore, GUI and text debugger and other places
significantly reduce code duplication over multiple modules
- 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
