- bx_shadow_bool_c: removed unused bitnum feature and changed data type.
- Changed return type of memory handlers to bool.
- Modified virtual timer, PIC and PIT code.
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 buffer for maximum 16 key events.
- PS/2 keyboard now sets the changed indicators only.
- Added support for the yellow status indicator in the win32 gui.
- Added HID code for the menu key.
- Added support for the yellow status indicator in the rfb and vncsrv guis.
- Cleaned up status indicator code in SDL, SDL2 and X guis.
- Unified USB keyboard and keypad code. Removed the keypad lookup table.
- Moved keyboard indicator stuff to the devices code and use it for both the
USB and legacy keyboard device. In the USB case a different color is used.
- In the SDL, SDL2 and X guis added new status indicator color yellow. It is
designed to be used by the USB keyboard (write flag 1 and "auto_off" flag 0).
- Added missing sysmbol to the German X11 keymap table.
TODO #1; Add some missing HID key codes.
TODO #2: Add key event queue to avoid losing events.
TODO #3: Unify keyboard and keypad code.
TODO #4: Support multiple non-modifier keys pressed at the same time.
TODO #5: Share keyboard indicators with the legacy PS/2 keyboard.
- Added NUMLOCK to the table of supported keys.
- Temporarily added status bar item for the keypad NUMLOCK indicator.
- TODO: Add new HID device "keyboard" with all keys supported.
- Added new devices method register_default_keyboard() and handle keyboard
events similar to the mouse stuff.
- Prepared removable keyboard support for the "paste bytes" feature.
- Store keyboard type in device object to avoid reading parameter at runtime.
- Related code cleanups.
- TODO #1: Extend USB keypad to full featured keyboard.
- TODO #2: Paste bytes support for USB keyboard.
It creates an array of strings from a string containing a comma separated list
of options. Now using this function for display library options, USB port
options and ROM image options.
be specified as a USB port option (e.g. 'sect_size:1024'). The values 512, 1024
and 4096 are supported. If not specified, it defaults to 512.
TODO: ATA disk (harddrv code), BIOS, bximage.
- Added new PCI chipset choice for the i440BX AGPset. Some basic work is done,
but AGP support is not present yet.
- Added new class for the "virtual" PCI-to-PCI bridge that should manage the
secondary bus (AGP). Since this device must appear with device number #1 at
the primary bus, it was required to change the PCI device numbers for the
i440BX case. Moved the PIIX4 module to device number #7. The presence of the
PCI base address regions now depends on the header type as expected.
- Since the Bochs BIOS cannot handle the modified PCI device layout, all tests
continued with an external BIOS designed for this chipset (GA-6BA_F1.bin).
This BIOS requires additional changes in some devices.
- ACPI: Return value 0 for some status registers and the GPI registers.
- CMOS: Since the PIIX4 supports a 256 byte CMOS RAM, prepared support for it
and enable it in case a 256 byte CMOS image is used.
- PCI: The device numbers for 4 slots starting at #8. The 5th slot could be
used for AGP when available.
- Added INT pin init to method init_pci_conf().
- Moved readonly register handling to the common PCI write handler.
- Moved IRQ line reporting to the common PCI write handler.
- Added new structure bx_pci_bar_t that contains all parameters related to the
PCI BARs (type, size, address and r/w handlers).
- Added new methods init_bar_io() and init_bar_mem() to set up the new structure
in the pci device init code.
- Added new method pci_write_handler_common() to handle writes to the normal
BARs and the ROM BAR. Writes to other registers are forwarded to the device
specific PCI write handlers. Removed BAR and ROM BAR handling from the
specific code.
- Added new method pci_bar_change_notify() to execute specific code after BAR
update (vga, ne2k).
- Moved normal BAR handling to method after_restore_pci_state().
- Store pointer to PCI device name in bx_pci_device_c and use it for i/o setup.
- usb_msd.cc: The Device Qualifier is valid for high speed devices only.
- uhci_core.cc: Don't report BX_DEBUG message if the current TD belongs to an
async operation that is still not complete.
- usb_common: init_device() now splits device name and primary option before
detecting device type.
- usb_hub: now completely handle port option in constructor.
- plugin.h: removed obsolete defines.
- 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.
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.
