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).

96193ed79c Finished bx_bool to bool type changes.
- Changes in the USB host controller code.
- Finally removed bx_bool type definition.
- NOTE: The Bochs BIOS still has it's own bx_bool definition.

89522c30d8 Some more bx_bool to bool type changes.

- Changed return type of memory handlers to bool.
- Modified virtual timer, PIC and PIT code.

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).

7412ebc07b Added new macros BX_DEBUG_PCI_READ and BX_DEBUG_PCI_WRITE to unify the debug
output of PCI config space handlers.

50c1370216 Some work on the PCI devices code.
- 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.

87145baf61 Rewrite of the PCI base address (BAR) handling to reduce code duplication.
- 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.

bd1eb0f862 Rewrite of the USB devices plugin code similar to the network driver code.
- 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.

c897ffa619 Cleanups in the Bochs system timer code
- Now using macro DEV_register_timer() in all devices and lowlevel modules.
- Removed unused timer stuff from the plugin.cc/.h code.

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.

e3e1665d6a Since all HCs now support asynchronous packet completion, we can enable the
async mode by default for all USB devices (used by disk, cdrom and floppy).
Whenever we implement a new HC model, it is still possible to set the async mode
to 0 until the async packet completion is working correctly.

9377281239 Prepare async packet code for the usage with xHCI. 2016-12-17 08:14:04 +00:00
Volker Ruppert
c3b608a3c9 Implemented USB remote wakeup mechanism.
- Extended USB callback definition to support different event types sent from
  device to HC. Currently we only have the two events "async completion" and
  "remote wakeup".
- Implemented event handlers in the UHCI, OHCI and EHCI. For the EHCI version
  we currently have no test case.
- The external USB hub now uses this feature at device connect/disconnect.
  Now the device change on the hub is correctly detected by the guest OS.
- TODO #1: remote wakeup and async completion for the xHCI.
- TODO #2: event handler for the external hub to make a USB device work on
  a chain of hubs.
- TODO #3: the event handler possibly could be used for the packet copy code.

a22e66ef13 Added support for multiple async packets on OHCI.
- Moved UHCI async packet functions to usb_common.h for using then on both
  UHCI and OHCI.
- Modified OHCI packet handling based on the UHCI implementation.
- Renamed EHCI helper function to avoid conflicts.
- TODO: async packet support on xHCI.

385ad83df3 Minor changes in the OHCI code.
- HcLSThreshold is writable, but it's usually not modified (same as Qemu).
- BX_ERROR should only occur on an attempt to change the number of ports.
- Don't register read-only items for save/restore.

4660c7ad98 Some work on USB HID devices and related stuff
- USB mouse and keypad now return NAK response when idle and there is no change.
- Implemented HID commands for get/set idle duration.
- Fixed NAK behaviour in UHCI and OHCI.
TODO list: USB tablet should also return NAK (doesn't work yet), review xHCI for
the NAK behaviour, accurate implementation of the idle duration

0192554c25 Started rewrite of USB packet handling required for full async packet support.

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.

364bf9362c Changed handling of unsupported/invalid device speed setup. The UHCI core now
ignores connected high speed device (fixes panic with EHCI on guest OS init or
shutdown). The other HC's now panic and disconnect device if the user decides
to continue.

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.

f3a6fbd235 Simplified setup of special runtime menus / dialogs

  as runtime options.

  each single parameter is no longer needed.

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.
