5a37532d08 input: introduce keyboard handler list
Add a linked list of keyboard handlers.  Added handlers will go
to the head of the list.  Removed handlers will be zapped from
the list.  The head of the list will be used for events.

This fixes the keyboard-dead-after-usb-kbd-unplug issue, key events
will be re-routed to the ps/2 kbd instead of being discarded.

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'/>

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:

Drop all the infrastructure for taddr properties (ie ones which

use would be rather questionable since device properties shouldn't
generally depend on a type that is conceptually variable based on
the target CPU. 32 or 64 bit integer properties should be used instead
as appropriate for the specific device.

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
   qemu -device vhost-scsi-pci,wwpn=naa.6001405bd4e8476d,event_idx=off

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.

The versatile_pci PCI controller has a set of control registers which
handle the mapping between PCI and system address spaces. Implement
these registers (though for now they have no effect since we don't
implement mapping PCI space into system memory at all).

The most natural order for our sysbus regions has the control
registers at the start, so move all the others down one.

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.

af60314291 vhost: Add vhost_commit callback for SeaBIOS ROM region re-mapping
This patch follows MST's recommendation to move checks for
vhost_verify_ring_mappings() -> cpu_physical_memory_map() operations
from MemoryListener->region_[add,del]() -> vhost_set_memory() into
final MemoryListener->commit() -> vhost_commit() callback.

It addresses the case where virtio-scsi vq ioport RAM re-mapping
to read-only SeaBIOS ROM triggers a cpu_physical_memory_map()
NIL MemoryRegionSection pointer failure.

Also save vhost_dev->mem_changed_[start,end]_addr values in
vhost_set_memory() for final ranges_overlap checks.  (Thanks Paolo!)

2b2325ff64 use libusb for usb-host
Reimplement usb-host on top of libusb.
Reasons to do this:

 (1) Largely rewritten from scratch, nice opportunity to kill historical
     cruft.
 (2) Offload usbfs handling to libusb.
 (3) Have a single portable code base instead of bsd + linux variants.
 (4) Bring usb-host support to any platform supported by libusbx.

For now this goes side-by-side to the existing code.  That is only to
simplify regression testing though, at the end of the day I want remove
the old code and support libusb exclusively.  Merge early in 1.5 cycle,
remove the old code after 1.5 release or something like this.

Thanks to qdev the old and new code can coexist nicely on linux.  Just
use "-device usb-host-linux" to use the old linux driver instead of the
libusb one (which takes over the "usb-host" name).

The bsd driver isn't qdev'ified so it isn't that easy for bsd.
I didn't bother making it runtime switchable, so you have to rebuild
qemu with --disable-libusb to get back the old code.

7598b41cfa usb-serial: Remove double call to qemu_chr_add_handlers( NULL )
usb-serial has a qdev chardev property, and hw/qdev-properties-system.c
already contains:

static void release_chr(Object *obj, const char *name, void *opaque)
{
    DeviceState *dev = DEVICE(obj);
    Property *prop = opaque;
    CharDriverState **ptr = qdev_get_prop_ptr(dev, prop);
    CharDriverState *chr = *ptr;

    if (chr) {
        qemu_chr_add_handlers(chr, NULL, NULL, NULL, NULL);
        qemu_chr_fe_release(chr);
    }
}

So doing the qemu_chr_add_handlers(s->cs, NULL, NULL, NULL, NULL); from
the usb handle_destroy function too will lead to it being done twice.

Implement flow control for the RX data path from xilinx_axienet->xilinx_axidma.
On short return from axidma, then ethernet sets up the notify callback to resume
transfer from where it left off.

This also allows the ethernet to track whether there is an in progress transaction
and return false from ethernet can_receive() as appropriate.

If the DMA backs up or is disabled it waits for enablement. When the rx stream IO
region is touched, the can_push() notify function is called if set.

No console switching needed.  No special support code in the
gfx card emulation needed.  Zap it all.  Also move ppm_save
out of the vga code and next to the qmp_screendump function.

For now screen dumping is limited to console #0 (like it used
to be), even though it is dead simple to extend it to other
consoles.  I wanna finish the console cleanup before setting

eb2f9b024d hw/vmware_vga.c: various vmware vga fixes.
Hardcode depth to 32 bpp.  It effectively was that way before because
that is the default surface depth, this just makes it explicit in the
code.

Rename depth to new_depth to make it consistent with the new_width +
new_height names.  In theory we can make new_depth changeable (i.e.
allow the guest to fill in -- say -- 16 there).  In practice the guests
don't try, the X-Server refuses to start if you ask it to use 16bpp
depth (via DefaultDepth in the Screen section).

Always return the correct rmask+gmask+bmask values for the given
new_depth.

Fix mode setting to also verify at new_depth to make sure we have a
correct DisplaySurface, even if the current video mode happes to be
16bpp (set by vgabios via bochs vbe interface).  While being at it
switch over to use qemu_create_displaysurface_from, so the surface is
backed by guest-visible video memory and we save a memcpy.

fe6c211781 qdev: Fix QOM unrealize behavior
Since commit 249d41720b (qdev: Prepare
"realized" property) setting realized = true would register the device's
VMStateDescription, but realized = false would not unregister it. Fix that.

Moving the code from unparenting also revealed that we were calling
DeviceClass::init through DeviceClass::realize as interim solution but
DeviceClass::exit still at unparenting time with a realized check.
Make this symmetrical by implementing DeviceClass::unrealize to call it,
while we're setting realized = false in the unparenting path.
The only other unrealize user is mac_nvram, which can safely override it.

Thus, mark DeviceClass::exit as obsolete, new devices should implement
DeviceClass::unrealize instead.

The sole available backend, tpm_passthrough, depends on the data
structures of the sole available frontend, tpm_tis.

However, we can at least try to split the user interface (tpm.c) from the
implementation (hw/tpm).  The patches makes tpm.c not include tpm_int.h,
which is shared between tpm_tis.c and tpm_passthrough.c; instead it
moves more stuff to tpm_backend.h.

aad64f3193 ide: refuse WIN_READ_NATIVE_MAX on empty device
What is the highest addressable sector on an empty CD-ROM?  Nothing is
addressable so produce an error.

This patch prevents a divide-by-zero in ide_set_sector() since
s->sectors and s->heads would be 0.  Not to mention that a sector=-1
argument would be nonsense.

Note that WIN_READ_NATIVE_MAX can be triggered using hdparm -N 1024
/dev/cdrom.  The LBA bit will be set to 1 though, so the only easy way
to go down the ide_set_sector() CHS code path which divides by zero is
to comment out the s->select & 0x40 case for testing.

32aea752f4 hw/nand.c: Fix nand erase operation
Usually, nand erase operation has only 2 or 3 address cycles.
We need to mask s->addr to zero unset stale high-order bytes in the nand address
before using it as the erase address.

This fixes the NAND erase operation in Linux.

1db8b5efe0 cadence_uart: Flush queued characters on reset
Reset can be used to empty the rx-fifo. As the fifo full condition is
used to return false from can_receive, queued rx data should be flushed
on reset accordingly.

fd7f8a99f3 pl330: Don't inhibit ES bits on INTEN
This if-else logic inhibits setting of the event status (ES) bits
when interrupts are enabled. This is incorrect. ES should be set
regardless on INTEN state. INTEN only inhibits the signalling of
events to PL330 threads, not setting of the ES register.

9246ce8811 Allow xen guests to plug disks of 1 TiB or more
The current xen backend driver implementation uses int64_t variables
to store the size of the corresponding backend disk/file. It also uses
an int64_t variable to store the block size of that image. When writing
the number of sectors (file_size/block_size) to xenstore, however, it
passes these values as 32 bit signed integers. This will cause an
overflow for any disk of 1 TiB or more.

This patch changes the xen backend driver to use a 64 bit integer write
xenstore function.

10bb3c6234 Introduce 64 bit integer write interface to xenstore
The current implementation of xen_backend only provides 32 bit integer
functions to write to xenstore. This patch adds two functions that
allow writing 64 bit integers (one generic function and another for
the backend only).

This patch also fixes the size of the char arrays used to represent
these integers as strings (originally 32 bytes, however no more than
12 bytes are needed for 32 bit integers and no more than 21 bytes are
needed for 64 bit integers).

c1a88ad1f4 Xen PV backend: Disable use of O_DIRECT by default as it results in crashes.
Due to what is almost certainly a kernel bug, writes with O_DIRECT may
continue to reference the page after the write has been marked as
completed, particularly in the case of TCP retransmit. In other
scenarios, this "merely" risks data corruption on the write, but with
Xen pages from domU are only transiently mapped into dom0's memory,
resulting in kernel panics when they are subsequently accessed.

This brings PV devices in line with emulated devices.  Removing
O_DIRECT is safe as barrier operations are now correctly passed
through.

See:
   http://lists.xen.org/archives/html/xen-devel/2012-12/msg01154.html
for more details.

86f425db3b Xen PV backend: Move call to bdrv_new from blk_init to blk_connect
This commit delays the point at which bdrv_new (and hence blk_open
on the underlying device) is called from blk_init to blk_connect.
This ensures that in an inbound live migrate, the block device is
not opened until it has been closed at the other end. This is in
preparation for supporting devices with open/close consistency
without using O_DIRECT. This commit does NOT itself change O_DIRECT
semantics.

c3037774be arm_gic: Fix sizes of state fields in preparation for vmstate support
In preparation for switching to vmstate for migration support, fix
the sizes of various GIC state fields. In particular, we replace all
the bitfields (which VMState can't deal with) with straightforward
uint8_t values which we do bit operations on. (The bitfields made
more sense when NCPU was set differently in different situations,
but we now always model at the architectural limit of 8.)
