      usb: claim port at device initialization time. · 891fb2cd
      由 Gerd Hoffmann 提交于 
      This patch makes qemu assign a port when creating the device, not when
attaching it.  For most usb devices this isn't a noticable difference
because they are in attached state all the time.

The change affects usb-host devices which live in detached state while
the real device is unplugged from the host.  They have a fixed port
assigned all the time now instead of getting grabbing one on attach and
releasing it at detach, i.e. they stop floating around at the usb bus.

The change also allows to simplify usb-hub.  It doesn't need the
handle_attach() callback any more to configure the downstream ports.
This can be done at device initialitation time now.  The changed
initialization order (first grab upstream port, then register downstream
ports) also fixes some icky corner cases.  For example it is not possible
any more to plug the hub into one of its own downstream ports.

The usb host adapters must care too.  USBPort->dev being non-NULL
doesn't imply any more the device is in attached state.  The host
adapters must additionally check the USBPort->dev->attached flag.

      usb: use iovecs in USBPacket · 4f4321c1
      由 Gerd Hoffmann 提交于 
      Zap data pointer from USBPacket, add a QEMUIOVector instead.
Add a bunch of helper functions to manage USBPacket data.
Switch over users to the new interface.

Note that USBPacket->len was used for two purposes:  First to
pass in the buffer size and second to return the number of
transfered bytes or the status code on async transfers.  There
is a new result variable for the latter.  A new status code
was added to catch uninitialized result.

Nobody creates iovecs with more than one element (yet).
Some users are (temporarely) limited to iovecs with a single
element to keep the patch size as small as possible.

      change all other clock references to use nanosecond resolution accessors · 74475455
      由 Paolo Bonzini 提交于 
      This was done with:

    sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \
        $(git grep -l 'qemu_get_clock\>' )
    sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \
        $(git grep -l 'qemu_new_timer\>' )

after checking that get_clock and new_timer never occur twice
on the same line.  There were no missed occurrences; however, even
if there had been, they would have been caught by the compiler.

There was exactly one false positive in qemu_run_timers:

     -    current_time = qemu_get_clock (clock);
     +    current_time = qemu_get_clock_ns (clock);

which is of course not in this patch.

      usb: class specific interface requests · f3571b1a
      由 Max Reitz 提交于 
      Mass Storage Reset and Get Max LUN are class specific requests, but
they were not marked as such in hw/usb-msd.c, moved therefore
ClassInterfaceRequest and ClassInterfaceOutRequest from hw/usb-net.c
to hw/usb.h.
Furthermore there was a problem in hw/usb-ohci.c when using DEBUG
concerning systems where size_t is a 32 bit integer (printf resulted
in a segmentation fault).
