Replace device_init() with generalized type_init().
While at it, unify naming convention: type_init([$prefix_]register_types)
Also, type_init() is a function, so add preceding blank line where
necessary and don't put a semicolon after the closing brace.

qdev_prop_set_* functions are always called by machine init functions
that should know what they're doing, so they abort on error. Still,
an assert(!errp) does not aid debugging. Print an error before aborting.

Add a field to XHCITransfer to correctly keep track of NAK'ed usb
packets. Retry transfers when the endpoint is kicked again. Implement
wakeup_endpoint bus op so we can kick the endpoint when needed.
With this patch applied the emulated hid devices are working correctly
when hooked up to xhci. usb-tabled without polling, yay!

Devices must specify which endpoint has data to transfer now.
The plan is to use the usb_wakeup() not only for remove wakeup support,
but for "data ready" signaling in general, so we can move away from
constant polling to event driven usb device emulation.

With the separation of the device lookup (via usb_find_device) and
packet processing we can lookup device and endpoint before setting up
the usb packet. So we can initialize USBPacket->ep early and keep it
valid for the whole lifecycle of the USBPacket. Also the devaddr and
devep fields are not needed any more.

There is no reason to have a separate usb_generic_handle_packet function
any more, fold it into usb_handle_packet(). Also call the do_token_*

packets only.

All drivers except usb-hub use usb_generic_handle_packet. The only
reason the usb hub has its own function is that it used to be called
with packets which are intended for downstream devices. With the new,
separate device lookup step this doesn't happen any more, so the need
for a different handle_packet callback is gone.
So we can kill the handle_packet callback and just call
usb_generic_handle_packet directly. The special hub handling in
usb_handle_packet() can go away for the same reason.

Implement the find_device callback for the usb hub. It'll loop over all
ports, calling usb_find_device for all enabled ports until it finds a

Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

Add usb_find_device(). This function will check whenever a device with
a specific address is connected to the specified port. Usually this
will just check state and address of the device hooked up to the port,
but in case of a hub it will ask the hub to check all hub ports for a
matching device.
This patch doesn't put the code into use yet, see the following patches
for details.
The master plan is to separate device lookup and packet processing.
Right now the usb code simply walks all devices, calls
usb_handle_packet() on each until one accepts the packet (by returning
something different that USB_RET_NODEV). I want to have a device lookup
first, then call usb_handle_packet() once, for the device which actually
processes the packet.

The USB subsystem pipes internal reset notifications through
usb_handle_packet() with a special magic PID. This indirection
is a pretty pointless excercise as it ends up being handled by
usb_generic_handle_packet anyway.
Replace the USB_MSG_RESET with a usb_device_reset() function
which can be called directly. Also rename the existing usb_reset()
function to usb_port_reset() to avoid confusion.

The OS is allowed to make the UHCI Controller run in circles. That is
usually done to serve multiple connected USB devices in a robin-round
fashion, so the available USB bandwidth is evenly distributed between
devices.
The uhci emulation handles this in a very poor way though. When it
figures it runs in circles it stops processing unconditionally, so
it usually processes at most a single transfer desriptor per queue,
even if there are multiple transfer descriptors are queued up.
This patch makes uhci act in a more sophisticated way. It keeps track
of successful processed transfer descriptors and transfered bytes. Then
it will stop processing when there is nothing to do (no transfer
descriptor was completed the last round) or when the transfered data
reaches the usb bandwidth limit.
Result is that the usb-storage devices connected to uhci are ten times
faster, mkfs.vfat time for a 64M stick goes down from five seconds to
a half second. Reason for this is that we are now processing up to 20
transfer descriptors (with 64 bytes each) per frame instead of a single
one.

bdrv_aio_cancel() can trigger bdrv_aio_flush() which makes all aio
that is currently in flight finish. So what we do is:
port reset
detect ncq in flight
cancel ncq
delete ncq sg list
at which point we have double freed the sg list. Instead, with this
patch we do:
port reset
detect ncq in flight
cancel ncq
check if we are really still in flight
delete ncq sg list
which makes things work and gets rid of the race.

To both avoid that kvm_irqchip_in_kernel always has to be paired with
kvm_enabled and that the former ends up in a function call, implement it
like the latter. This means keeping the state in a global variable and
defining kvm_irqchip_in_kernel as a preprocessor macro.
