- Store the Voodoo model in structure bx_voodoo_t.
- The PCI initEnable register of the Voodoo2 model has a read-only secondary
revision ID in bits 12..15. Now the Voodoo2 is correctly detected by the
Windows driver, but display is not yet working (blank screen).
- Reset now disables VGA override.
- PCI: Moved PCI device base class methods to the end of file devices.cc and
re-define LOG_THIS to use the correct log module and prefix.
- Created framework based on our I/O APIC code and ported HPET core from Qemu
with some required changes for the Bochs timer and IRQ handling.
- Enabled HPET-specific code in the ACPI and rombios32 sources and generated
new ACPI table with iasl.
- The HPET device plugin is now always loaded if the i440FX chipset is selected
(same as ACPI). We have to rethink this when we have implemented a more
modern chipset.
- TODO: Rewrite of the virtual timer code for nanosecond support to make the
realtime synchronization possible with HPET.
directly sent to the optional keyboard (USB keypad). It is now independent
from the legacy keyboard and the check for supported keys is simplified. The
legacy keyboard still receives the unhandled key event, but now sent from the
common devices code.
bx_devmodel_c. The early version of the combined vga / svga_cirrus code
required the now obsolete implementation. Some related cleanups in the
devices code.
- Since the pci_read_handler() method is identical in most devices, move it
to the base class to reduce code duplication. Only the 'pcidev' device has
it's own implementation (NOTE: it is not maintained yet).
- Minor other fixes and cleanups in some PCI devices.
- Removed "pseudo device plugin" containing common code and specific drivers.
- Moved network module base classes and module handling to the Bochs core.
Now loading network driver plugins in netmod.cc.
- Moved shared networking code used by the 'vnet' driver and 'bxhub' from
netmod.cc/.h to new files netutil.cc/.h.
- Created separate plugins for each network driver implementation.
- Modified Bochs plugin system to support new plugin type PLUGTYPE_NETWORK.
- Renamed OSS sound driver files from soundlnx.cc/.h to soundoss.cc/.h.
- Removed "pseudo device plugin" containing common code and specific drivers.
- Moved common sound code, base classes of sound drivers and the dummy driver
to the Bochs core. Now loading sound driver plugins in soundmod.cc.
- Created separate plugins for the platform/library specific drivers and the
"file" driver.
- Modified Bochs plugin system to support now plugin type PLUGTYPE_SOUND.
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.
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.
- 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
- 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
- read PCI confAddr value from the devices code for debugger output
- PCI confData value isn't needed at all (changes by each read / write access)
- PCI framework methods don't need to be virtual
- PCI slot configuration, memory and i/o BAR registration, PCI i/o space
handlers now present in devices.cc
- configure: E1000 emulation and USB support need PCI
- vga: fixes for the non-PCI case
- uninstall parameter handlers (floppy, keyboard)
- unload plugin that cannot be removed automatically
- wx: removed "show keyboard" demo and some other cleanups
- TODO: remove wx debugger and make wx work with the enhanced gui debugger
- new gui method set_mouse_mode_absxy() should switch the gui to absolute
x/y mode
- new DEV_mouse_motion() argument 'absxy' indicates whether or not the gui
sends absolute x/y values
- USB tablet code prepared to use the new feature
- TODO: implement this feature for each gui (sdl, win32, wx, x, ...)
- ne2k: replaced debugger command 'info ne2k' completely by a new version based
on 'info device' with additional arguments and removed all of the now obsolete
stuff (ne2k device stub, macro for print_info())
- pci: added option 'dump=full' for the debugger command 'info device' to show
the whole PCI config space
- TODO: some other devices could have support for additional options in
debug_dump()
- added new class bx_vgacore_c containing the core of the standard VGA
emulation. This is now the base class for both vga and cirrus.
- created 2 separate plugins 'vga' (for standard VGA and VBE) and 'svga_cirrus'
(Cirrus emulation). The vga extension option is used to select which plugin
should be loaded.
- TODO: move the pcivga code to the VGA/VBE code, add subdirectory for display
adapters, severak improvements and cleanups
plugin system.The load order is important for these devices!
- load support plugins for networking, sound and usb only if at least one of the
related plugin devices is loaded.
- plugin_ctrl: added missing devices to the list in bochsrc sample
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)
nearly all cases and plugins that depend on others. These plugins cannot be
managed with 'plugin_ctrl' (e.g. keyboard, harddrv, pci_ide). Store the plugin
type in the divice structure for compatiblity with the "no-plugin" compilation.
Call the device methods init(), reset() and after_restore_state() for each type
separately in the order: stanard, optional, user. This also affects the status
bar LED feature: now the keyboard and harddrv LEDs are always visible, but
those of optional plugins may be invisible if there is no space left.
- TODO #1: add the devices 'ne2k' and 'sb16' to 'plugin_ctrl'
- TODO #2: manage core plugins with the device plugin system
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'
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
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
