Dmitry Eremin-Solenikov aa9438d9f8 scoop: fix access to registers from second instance
Second instance of scoop contains registers shifted to 0x40 from the start
of the page. Instead of messing with register mapping, just limit register
address to 0x00..0x3f.

Michael Tokarev a8fb7ff3fd USB keyboard emulation key mapping error
The USB keyboard emulation's translation table in hw/usb-hid.c doesn't
match the codes actually sent for the Logo (a.k.a. "Windows") or Menu
keys. This results in the guest OS not being able to receive these keys
at all when the USB keyboard emulation is being used.

In particular, both the keymap in /usr/share/kvm/keymaps/modifiers and
the evdev table in x_keymap.c map these keys to 0xdb, 0xdc, and 0xdd,
while usb_hid_usage_keys[] seems to be expecting them to be mapped to
0x7d, 0x7e, and 0x7f.

The attached patch seems to fix the problem, at least in my (limited)
testing.

Gerd Hoffmann 5f69076b8d usb: add port property.
This allows to explictily set the physical port where you want to
plug the usb device.  Example:

  -device usb-tablet,bus=usb.0,port=2

With explicit port addressing qemu can and will not automagically add
USB Hubs.  This means that:

  (a) You can plug two devices of your choice into the two uhci
      root ports.
  (b) If you want plug in more that two devices you have to care
      about adding a hub yourself.

Plugging a hub works this way:

  -device usb-hub,bus=usb.0,port=1

Use this to add a device to the hub:

  -device usb-tablet,bus=usb.0,port=1.1

Gerd Hoffmann 7b074a22da usb: hid: change serial number to "42".
It would be nice to have some way to signal our hid devices support
remote wakeup.  There is a descriptor bit for that of course.  Problem
with using is one is that older qemu versions used to set the bit even
though they did *not* support remote wakeup.  Bummer.

This patch changes the serial number of our hid devices from "1" to "42"
to signal "it is safe to enable remote wakeup".  The serial number was
choosen because it isn't used for anything and it is available in sysfs
so it is easy to match it using udev rules like this:

ACTION=="add", SUBSYSTEM=="usb", \
	ATTR{product}=="QEMU USB Tablet", ATTR{serial}=="42", \

This patch adds hw/usb-desc.[ch] files.  They carry data structures
for various usb descriptors and helper functions to generate usb

The intention is to have a internal representation of the device

so we can have common code handle common usb device emulation using
the device description.

The usage of this infrastructure is optional for usb drivers as there
are cases such as pass-through where it probably isn't very useful.

Stefan Hajnoczi 25db9ebe15 virtio-pci: Use ioeventfd for virtqueue notify
Virtqueue notify is currently handled synchronously in userspace virtio.  This
prevents the vcpu from executing guest code while hardware emulation code
handles the notify.

On systems that support KVM, the ioeventfd mechanism can be used to make
virtqueue notify a lightweight exit by deferring hardware emulation to the
iothread and allowing the VM to continue execution.  This model is similar to
how vhost receives virtqueue notifies.

The result of this change is improved performance for userspace virtio devices.
Virtio-blk throughput increases especially for multithreaded scenarios and
virtio-net transmit throughput increases substantially.

Some virtio devices are known to have guest drivers which expect a notify to be
processed synchronously and spin waiting for completion.
For virtio-net, this also seems to interact with the guest stack in strange
ways so that TCP throughput for small message sizes (~200bytes)
is harmed. Only enable ioeventfd for virtio-blk for now.

Care must be taken not to interfere with vhost-net, which uses host
notifiers.  If the set_host_notifier() API is used by a device
virtio-pci will disable virtio-ioeventfd and let the device deal with
host notifiers as it wishes.

Finally, there used to be a limit of 6 KVM io bus devices inside the
kernel.  On such a kernel, don't use ioeventfd for virtqueue host
notification since the limit is reached too easily.  This ensures that
existing vhost-net setups (which always use ioeventfd) have ioeventfds
available so they can continue to work.

After migration and on VM change state (running/paused) virtio-ioeventfd
will enable/disable itself.

 * VIRTIO_CONFIG_S_DRIVER_OK -> enable virtio-ioeventfd
 * !VIRTIO_CONFIG_S_DRIVER_OK -> disable virtio-ioeventfd
 * virtio_pci_set_host_notifier() -> disable virtio-ioeventfd
 * vm_change_state(running=0) -> disable virtio-ioeventfd
 * vm_change_state(running=1) -> enable virtio-ioeventfd

Alex Williamson c574ba5a4c rtl8139: Use subsection to restrict migration after hotplug
rtl8139 includes a cpu_register_io_memory acquired value in it's
migration data.  This is not only unecessary, but we should treat
these values as unique to the VM instances since the value depends
on call order.  In most cases, this miraculously still works.
However, if devices are added or removed from the system, it may
represent an ordering change, which could cause the target rtl8139
device to make use of another device's cpu_register_io_memory value.
If we detect that a hot-add/remove has occured, include a subsection
to restrict migrations only to driver versions known to include this
fix.

Alex Williamson 0ac8ef7132 qdev: Track runtime machine modifications
Create a trivial interface to track whether the machine has been
modified since boot.  Adding or removing devices will trigger this
to return true.  An example usage scenario for such an interface is
the rtl8139 driver which includes a cpu_register_io_memory() value
in it's migration stream.  For the majority of migrations, where
no hotplug has occured in the machine, this works correctly.  Once
the machine is modified, we can use this interface to detect that
and include a subsection for the device to prevent migrations to
rtl8139 versions with this bug.

Aurelien Jarno 92d675d1c1 cirrus_vga: fix division by 0 for color expansion rop
Commit d85d0d3883 introduces a regression
with Windows ME that leads to a division by 0 and a crash.

It uses the color expansion rop with the source pitch set to 0. This is
something allowed, as the manual explicitely says "When the source of
color-expand data is display memory, the source pitch is ignored.".

This patch fixes this regression by computing sx, sy and others
variables only if they are going to be used later, that is for a plain
copy ROP. It basically consists in moving code.

Aurelien Jarno 9ae19b657e Fix curses on big endian hosts
On big endian hosts, the curses interface is unusable: the emulated
graphic card only displays garbage, while the monitor interface displays
nothing (or rather only spaces).

The curses interface is waiting for data in native endianness, so
console_write_ch() should not do any conversion. The conversion should
be done when reading the video buffer in hw/vga.c. I supposed this
buffer is in little endian mode, though it's not impossible that the
data is actually in guest endianness. I currently have no big endian
guest to way (they all switch to graphic mode immediately).

The device path used for migration is currently broken for
for all devices behind a nested bridge.

Replace this by a hierarchical list of slot/function numbers, walking
the path from root down to device. Add :00 after the domain number
so that if there are no nested bridges, this is compatible
with what we have now.

Note: as pointed out by Gleb, using openfirmware paths
might be cleaner, doing this would break compatibility though,
and the IDs used are not guest or user visible at all,
so breaking the compatibility is probably not worth it.

> This is caused because the reset function for pcnet is no

The issue is, it is assumed that all qbuses, qdeves are under
main_system_bus. But there are qbuses whose parent is NULL. So it
is necessary to trigger reset for those qbuses.
(On the other hand, if NULL is passed to qdev_create(), its parent bus
is main_system_bus.)
Ideally those buses should be moved under bus controller
device which is qdev. But it's not done yet.
So register qbus reset handler for qbus whose parent is NULL.
