- 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.
- USB xHCI NAK handling fix by Ben. Now openSUSE 13.2 boots without hang with
hub connected to an xHCI port.
- Updated Ben's email address and year in some copyright headers.
- 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.
- 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.
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.
