719592e2f3 Fixed device connect failure handling in all HCs (reset port parameters).
The old code has blocked the port after failure.

4dd5816108 Some changes in the Bochs plugins code.
- 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.

b84c6c8526 Some changes in the device config handling in all HCs and external hub.
- 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.

16d79cbf0b Some fixes and cleanups in the USB code.
- 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.

919d82b68e Next step of USB devices handling rewrite. Changed type of the device parameter
to bx_param_enum_c. Updated code to provide support for legacy syntax
(portX="device:option").
TODO: generate USB devices list from plugins list.

e00a5d0761 Started rewrite of the USB devices handling.
- 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.

0d425037df Improved plugin type detection at Bochs startup.
- 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).

8db0a2b001 Replaced the plugin init / fini functions with one single function called
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).

e7093e74d8 Started implementing the i440BX PCI/AGP chipset.
- 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.

d46a9b7205 Some work on the PCI 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.

17b4e65bef The save/restore list for USB devices is now cleared by the device destructor
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.

2f94f55a82 Some work in the UHCI core for the usage as a companion controller of EHCI.
- 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.

d455659bd1 Split the USB UHCI code in two parts: uhci_core.cc implements the device
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.

491dc311ca Some work for asynchronus USB packet handling (needed by disk/cdrom seek emulation).
- 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.

696c1a6e55 Some Bochs features are still called "experimental". The bus mouse, USB OHCI,
USB UHCI and the E1000 NIC are known to work fine on some guest systems, so
it's safe to remove this attribute.

- 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

db633275b0 - several improvements to the optional plugin control
- 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.
