- Changed variable type of the plugin_t "type" member from enum to Bit16u.
- Added support for returning device flags with the new mode PLUGIN_FLAGS in
the plugin entry functions. It is currently only used for devices that can
be connected to a PCI slot.
- Code cleanup in core device plugins: checking type no longer necessary.
- The "non-plugin" mode now also uses the "loadtype" member of plugin_t.
TODO: Change PCI slot options to bx_param_enum_c and build the choices list
using the new capabilities of the plugin API.
- Disable port "options" parameter after successful connect. While connected,
a device may install runtime options to control it's behaviour.
- Added enable handlers for the "options" parameter to ensure an attempt to
change the device while connected doesn't enable it.
- Some related code cleanups.
- USB hub: disable device "options" parameter if device is set to "none".
- USB hub: handle device disconnect in runtime_config().
- Removed handling of USB device type in host controllers and external hub.
- Moved main option from the portX parameter to the optionsX parameter. Added
new option "path" for the disk, cdrom and floppy devices, "ports" for the
USB hub and "file" for the USB printer. The legacy syntax is still supported.
- Register USB device state after init() to ensure all options that may have
effect on the save/restore list are applied.
- Report available devices on top of log file similar to hdimage, network and
sound modules.
- Changed USB device type variable typein host controllers to int.
- Prepared improved usbdev_ctl init / exit implementation.
- TODO: Create list of USB devices dynamicly from available plugins.
- Added special mode to all plugin entry functions that returns the plugin type.
- The plugins search function now temporarily loads all available plugins and
reads the plugin type using the new mode PLUGIN_PROBE.
- Added "loadtype" to the plugin structure to store the type used for plugin
loading (currently only the voodoo plugin provides two types).
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 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.
- 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.
instead of the hub's remove_device() method. The external hub removes connected
devices before clearing it's own list. This fixes crash on exit when devices
are present on external hub.
- added method to change port ownership.
- fixed UHCI reset and initialized device pointers.
- added symbol UHCI_FULL_DEBUG to reduce debug output if not set.
- renamed connection handling method.
emulation and usb_uhci.cc implements the setup for the PIIX3 chipset and the
runtime device change code. The UHCI core is required for the EHCI emulation,
since there can be multiple "companion" controllers for USB 1.1 device handling.
- Common USB code prepared for async USB packet handling (ported from an earlier
Qemu version).
- Added simple async packet handling to OHCI (partly ported from earlier Qemu).
- Implemented USB cdrom seek emulation for hubs with async packet support. The
legacy code is still present for hubs without this feature.
- For UHCI and xHCI the callback is set to NULL to force the usage of the
legacy cdrom read code.
TODO: clean up OHCI code, async support for UHCI and xHCI, seek emulation for
USB harddisk and floppy.
- Force a status bar update after unregistering an item.
- Added status indicators for USB disk and cdrom.
- Handle USB device disconnect in the runtime config handler, too.
devices like USB disk, cdrom or floppy. Using this feature for the new USB
floppy. Removed static indicators for port activity from the USB HC code.
TODO: Implement status LEDs for USB disk and cdrom.
USB UHCI and the E1000 NIC are known to work fine on some guest systems, so
it's safe to remove this attribute.
TODO: Some other Bochs features need to be reviewed for this.
- removed max_packet_size member from USB device structure
- usb_uhci: improved speed info
- updated USB-related documentation
- TODO: review and test the main part of the xHCI changes by Ben
- If the runtime flag of a bx_list_c object is set, all it's items are set up
as runtime options.
- Set the runtime parameter for all top-level runtime-only lists. Setting up
each single parameter is no longer needed.
- 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
- 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
add the LGPL to usb_hid.cc
- moved Ben's comment to usb_uhci.cc, since this file contains most of his
initial pciusb patch
- TODO: implement full USB keyboard support (port from QEMU)
- 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.
- siminterface: don't create plugin parameter if it already exists
- wx: make sure all plugins are loaded when creating plugin control dialog
- USB HC's: fixed removal of parameters when unloading plugin
