usb: add usb_handle_packet

Add a usb_handle_packet function, put it into use everywhere.
Right now it just calls dev->info->handle_packet(), that will
change in future patches though.

usb: move cancel callback to USBDeviceInfo

Remove the cancel callback from the USBPacket struct, move it over
to USBDeviceInfo. Zap usb_defer_packet() which is obsolete now.

usb: Pass the packet to the device's handle_control callback

This allows using the generic usb_generic_handle_packet function from
device code which does ASYNC control requests (such as the linux host
pass through code).

usb-linux: use usb_generic_handle_packet()

Make the linux usb host passthrough code use the usb_generic_handle_packet()
function, rather then the curent DYI code. This removes 200 lines of almost
identical code.

usb: control buffer fixes

Windows allows control transfers to pass up to 4k of data, so raise our
control buffer size to 4k. For control out transfers the usb core code copies
the control request data to a buffer before calling the device's handle_control...

usb: add attach callback

Add handle_attach() callback to USBDeviceInfo which is called by the
generic package handler when the device is attached to the usb bus
(i.e. plugged into a port).

usb: rework attach/detach workflow

Add separate detach callback to USBPortOps, split
uhci/ohci/musb/usbhub attach functions into two.

Move common code to the usb_attach() function, only
the hardware-specific bits remain in the attach/detach
callbacks.

Keep track of the port it is attached to for each usb device....

usb: add usb_wakeup() + wakeup callback to port ops

Add wakeup callback to port ops for remote wakeup handling.
Also add a usb_wakeup() function for devices which want
trigger a remote wakeup.

qdev/usb: add usb bus support to qdev, convert drivers.

  • Add USBBus. * Add USBDeviceInfo, move device callbacks here. * Add usb-qdev helper functions. * Switch drivers to qdev.

TODO: * make the rest of qemu aware of usb busses and kill the FIXMEs
added by this patch....

usb: generic packet handler cleanup and documentation (Max Krasnyansky)

A bit better documentation of the USB device API, namely
return codes.
Rewrite of usb_generic_handle_packet() to make it more
reable and easier to follow.
