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.

f82bb13f88 Added support for multiple async packets on UHCI (TODO: other HCs). 2016-11-22 18:06:44 +00:00

72af99c372 Some more work on USB HID devices and related stuff
- Now really fixed NAK behaviour in UHCI.
- USB tablet now also returns NAK response when idle and there is no change.

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.
Step #1: Allocate buffer for data transfers dynamicly with the required size
(done in UHCI, OHCI and EHCI).

de6ee1d7eb Added basic async packet support in the UHCI core. Only one async operation
is currently supported per hub at the same time (same as OHCI).
TODO #1: We should support at least one async operation per connected device.
TODO #2: Async packet support for EHCI and xHCI.

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.

5e635a87bb Fixed IRQ sharing for multi-function PCI devices and removed workaround in the
UHCI core code.

e19f28dad7 Call DEV_pci_set_irq() only if the IRQ level really changes. The Bochs IRQ
routing code is possibly buggy, since it can make multiple UHCI devices fail
in a multi-function device (like EHCI).

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.
