d7d218ef02 dev-smartcard-reader: change default protocol to T=0
We don't support T=1 so we shouldn't advertise it by default.

Two independent changes:
* Default ATR
 sets T=0. This gets overwritten by the client provided ATR later.
* Class descriptor
 changes dwAdvertise dwProtocols.PPPP to 0x1 and dwProtocols.RRRR=0 per spec.

b16352acf3 ccid-card-passthru, dev-smartcard-reader: add debug environment variables
Introduces a new utility function: parse_debug_env to avoid code
duplication.

This overrides whatever debug value is set on the corresponding devices
from the command line, and is meant to ease the usage with any
management stack. For libvirt you can set environment variables by
extending the dom namespace, i.e:

<domain type='kvm' id='3' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
  <qemu:commandline>
    <qemu:env name='QEMU_CCID_PASSTHRU_DEBUG' value='4'/>
    <qemu:env name='QEMU_CCID_DEBUG' value='4'/>
  </qemu:commandline>
</domain>

e449f26bed ehci_free_packet: Discard finished packets when the queue is halted
With pipelining it is possible to encounter a finished packet when cleaning
the queue due to a halt. This happens when a non stall error happens while
talking to a real device. In this case the queue on the usb-host side will
continue processing packets, and we can have completed packets waiting in
the queue after an error condition packet causing a halt.

There are 2 reasons to discard the completed packets at this point, rather
then trying to writing them back to the guest:

1) The guest expect to be able to cancel and/or change packets after the
packet with the error without doing an unlink, so writing them back may
confuse the guest.

2) Since the queue does not advance when halted, the writing back of these
packets will fail anyways since p->qtdaddr != q->qtdaddr, so the
ehci_verify_qtd call in ehci_writeback_async_complete_packet will fail.

Note that 2) means that then only functional change this patch introduces
is the printing of a warning when this scenario happens.

Note that discarding these packets means that the guest driver and the device
will get out of sync! This is unfortunate, but should not be a problem since
with a non stall error (iow an io-error) the 2 are out of sync already anyways.
Still this patch adds a warning to signal this happening.

Note that sofar this has only been seen with a DVB-T receiver, which gives
of a MPEG-2 stream, which allows for recovering from lost packets, see:

5e9be92d77 vhost-scsi: new device supporting the tcm_vhost Linux kernel module
The WWPN specified in configfs is passed to "-device vhost-scsi-pci".
The tgpt field of the SET_ENDPOINT ioctl is obsolete now, so it is not
available from the QEMU command-line.  Instead, I hardcode it to zero.

Changes in Patch-v2:
   - Add vhost_scsi_get_features() in order to determine feature bits
     supports by host kernel (mst + nab)
   - Re-enable usage of DEFINE_VIRTIO_COMMON_FEATURES, and allow
     EVENT_IDX to be disabled by host in vhost_scsi_get_features()
   - Drop unused hotplug bit in DEFINE_VHOST_SCSI_PROPERTIES

Changes in Patch-v1:
   - Set event_idx=off by default (nab, thanks asias)
   - Disable hotplug feature bit for v3.9 tcm_vhost kernel code, need to
     re-enable in v3.10 (nab)
   - Update to latest qemu.git/master HEAD

Changes in WIP-V3:
   - Drop ioeventfd vhost_scsi_properties (asias, thanks stefanha)
   - Add CONFIG_VHOST_SCSI (asias, thanks stefanha)
   - Add hotplug feature bit

Changes in WIP-V2:
   - Add backend guest masking support (nab)
   - Bump ABI_VERSION to 1 (nab)
   - Set up set_guest_notifiers (asias)
   - Set up vs->dev.vq_index (asias)
   - Drop vs->vs.vdev.{set,clear}_vhost_endpoint (asias)
   - Drop VIRTIO_CONFIG_S_DRIVER check in vhost_scsi_set_status (asias)

Howto:
   Use the latest seabios, at least commit b44a7be17b
   git clone git://git.seabios.org/seabios.git
   make
   cp out/bios.bin /usr/share/qemu/bios.bin

dcc6ceffc0 virtio-balloon: fix integer overflow in BALLOON_CHANGE QMP event
Because dev->actual is uint32_t, the expression 'dev->actual <<
VIRTIO_BALLOON_PFN_SHIFT' is truncated to 32 bits. This overflows when
dev->actual >= 1048576.

To reproduce:

 1. Start a VM with a QMP socket and 5G of RAM
 2. Connect to the QMP socket, negotiate capabilities and issue:

   { "execute":"balloon", "arguments": { "value": 1073741824 } }

 3. Watch for BALLOON_CHANGE QMP events, the last one will incorretly be:

   { "timestamp": { "seconds": 1366228965, "microseconds": 245466 },
     "event": "BALLOON_CHANGE", "data": { "actual": 5368709120 } }

To fix it this commit casts it to ram_addr_t, which is ram_size's type.

66a96d7018 versatile_pci: Implement the correct PCI IRQ mapping
Implement the correct IRQ mapping for the Versatile PCI controller; it
differs between realview and versatile boards, but the previous QEMU
implementation was correct only for the first PCI card on a versatile
board, since we weren't swizzling IRQs based on the slot number.

Since this change would otherwise break any uses of PCI on Linux kernels
which have an equivalent bug (since they have effectively only been
tested against QEMU, not real hardware), we implement a mechanism
for automatically detecting those broken kernels and switching back
to the old mapping. This works by looking at the values the kernel
writes to the PCI_INTERRUPT_LINE register in the config space, which
is effectively the interrupt number the kernel expects the device
to be using.

5f37ef92b7 versatile_pci: Put the host bridge PCI device at slot 29
On real hardware the host bridge appears as a PCI device in slot 29,
so make QEMU put its host bridge in that slot too.

967c260749 versatile_pci: Use separate PCI I/O space rather than system I/O space
Rather than overloading the system I/O space (which doesn't even make
any sense on ARM) for PCI I/O, create an memory region in the PCI
controller and use that to represent the I/O space.

0688810b41 versatile_pci: Change to subclassing TYPE_PCI_HOST_BRIDGE
Change versatile_pci to subclass TYPE_PCI_HOST_BRIDGE and generally
handle PCI in a more QOM-like fashion.

cd93dbf375 versatile_pci: Update to realize and instance init functions
Update the Versatile PCI controller to use a realize function rather
than SysBusDevice::init. To reflect the fact that the 'realview_pci'
class is taking most of its implementation from 'versatile_pci' (and
to make the QOM casts work) we make 'realview_pci' a subclass of
'versatile_pci'.

5fb8084f31 versatile_pci: Expose PCI I/O region on Versatile PB
Comments in the QEMU source code claim that the version of the PCI
controller on the VersatilePB board doesn't support the PCI I/O
region, but this is incorrect; expose that region, map it in the
correct location, and drop the misleading comments.

This change removes the only currently implemented difference
between the realview-pci and versatile-pci models; however there
are other differences in not-yet-implemented functionality, so we
retain the distinction between the two device types.
