c7020c9740 usb-ehci: drop assert()
Not sure what the purpose of the assert() was, in any case it is bogous.
We can arrive there if transfer descriptors passed to us from the guest
failed to pass sanity checks, i.e. it is guest-triggerable.  We deal
with that case by resetting the host controller.  Everything is ok, no
need to throw a core dump here.

96dd9aac37 usb-host: rewrite usb_linux_update_endp_table
This patch carries a complete rewrite of the usb descriptor parser.
Changes / improvements:

 * We are using the USBDescriptor struct instead of hard-coded offsets
   now to access descriptor data.
 * (debug) printfs are all gone, tracepoints have been added instead.
 * We don't try (and fail) to skip over unneeded descriptors.  We parse
   them all one by one.  We keep track of which configuration, interface
   and altsetting we are looking at and use this information to figure
   which desciptors are in use and which we can ignore.
 * On parse errors we clear all endpoint information, which will
   disallow any communication with the device, except control endpoint
   messages.  This makes sure we don't end up with a silly device state
   where half of the endpoints got enabled and the other half was left
   disabled.
 * Some sanity checks have been added.

The new parser is more robust and also leaves complete device
information in the trace log if you enable the ush_host_parse_*
tracepoints.

58ea88d87a usb-ehci: frindex always is a 14 bits counter
frindex always is a 14 bits counter, and not a 13 bits one as we were
emulating. There are some subtle hints to this in the spec, first of all
"Table 2-12. FRINDEX - Frame Index Register" says:
"Bit 13:0 Frame Index. The value in this register increments at the end of
each time frame (e.g. micro-frame). Bits [N:3] are used for the Frame List
current index. This means that each location of the frame list is accessed
8 times (frames or micro-frames) before moving to the next index. The
following illustrates values of N based on the value of the Frame List
Size field in the USBCMD register.

USBCMD[Frame List Size]	Number Elements		 N
00b				1024		12
01b				 512		11
10b				 256		10
11b			    Reserved"

Notice how the text talks about "Bits [N:3]" are used ..., it does
NOT say that when N == 12 (our case) the counter will wrap from 8191 to 0,
or in otherwords that it is a 13 bits counter (bits 0 - 12).

The other hint is in "Table 2-10. USBSTS USB Status Register Bit Definitions":

"Bit 3 Frame List Rollover - R/WC. The Host Controller sets this bit to a one
when the Frame List Index (see Section 2.3.4) rolls over from its maximum value
to zero. The exact value at which the rollover occurs depends on the frame
list size. For example, if the frame list size (as programmed in the Frame
List Size field of the USBCMD register) is 1024, the Frame Index Register
rolls over every time FRINDEX[13] toggles. Similarly, if the size is 512,
the Host Controller sets this bit to a one every time FRINDEX[12] toggles."

Notice how this text talks about setting bit 3 when bit 13 of frindex toggles
(when there are 1024 entries, so our case), so this indicates that frindex
has a bit 13 making it a 14 bit counter.

Besides these clear hints the real proof is in the pudding. Before this
patch I could not stream data from a USB2 webcam under Windows XP, after
this cam using a USB2 webcam under Windows XP works fine, and no regressions
with other operating systems were seen.

92615a5ab9 pseries: Fix RTAS based config access
On the pseries platform, access to PCI config space is via RTAS calls(
which go to the hypervisor) rather than MMIO.  This means we don't use
the same code path as nearly everyone else which goes through pci_host.c
and we're missing some of the parameter checking along the way.

We do have some parameter checking in the RTAS calls, but it's not enough.
It checks for overruns, but does not check for unaligned accesses,
oversized accesses (which means the guest could trigger an assertion
failure from pci_host_config_{read,write}_common().  Worse it doesn't do
the basic checking for the number of RTAS arguments and results before
accessing them.

This patch fixes these bugs.

5f2e2ba262 pseries: Consolidate hack for RTAS display-character usage
Currently the pseries machine contains not one but two somewhat ugly hacks
to allow printing of early debug messages before the guest has properly
read the device tree.

First, we special case H_PUT_TERM_CHAR so that a vtermno of 0 (usually
invalid) will look for a suitable vty and use that.  This supports Linux's
early debug code which will use H_PUT_TERM_CHAR with vtermno==0 before
reading the device tree.  Second, we support the RTAS display-character call.
This takes no vtermno so we assume the address of the default first VTY.

This patch makes things more consistent by folding the second hack into the
first.  Now, display-character uses the existing vty_lookup() function to
do the same search for a suitable VTY.

7faa8075d8 acpi_piix4: Fix PCI hotplug race
As Michael Tsirkin demonstrated, current PCI hotplug is vulnerable
to a few races.  The first is a race with other hotplug operations
because we clear the up & down registers at each event.  If a new
event comes before the last is processed, up/down is cleared and
the event is lost.

To fix this for the down register, we create a life cycle for
the event request that starts with the hot unplug request in
piix4_device_hotplug() and ends when the device is ejected.
This allows us to mask and clear individual bits, preserving them
against races.  For the up register, we have no clear end point
for when the event is finished.  We could modify the BIOS to
acknowledge the bit and clear it, but this creates BIOS compatibiliy
issues without offering a complete solution.  Instead we note that
gratuitous ACPI device checks are not harmful, which allows us to
issue a device check for every slot.  We know which slots are present
and we know which slots are hotpluggable, so we can easily reduce
this to a more manageable set for the guest.

The other race Michael noted was that an unplug request followed
by reset may also lose the eject notification, which may also
result in the eject request being lost which a subsequent add
or remove.  Once we're in reset, the device is unused and we can
flush the queue of device removals ourselves.  Previously if a
device_del was issued to a guest without ACPI PCI hotplug support,
it was necessary to shutdown the guest to recover the device.
With this, a guest reboot is sufficient.

544d1afa70 hw/arm_gic: Expose PPI inputs as gpio inputs
Expose the Private Peripheral Interrupt inputs as GPIO inputs.
The layout of the GPIO array is thus:
  [0..N-1] SPIs
  [N..N+31] PPIs for CPU 0
  [N+32..N+63] PPIs for CPU 1
  ...

Treating PPIs as being another kind of input line is in line with the
GIC architecture specification, where they are clearly described that
way. The 11MPCore TRM is a bit more ambiguous, but there is no practical
difference between "set PPI X as pending" and "0->1 transition on a
PPI input line configured as edge triggered", and PPIs are always
edge triggered, so this change won't affect behaviour.

3e48dd4a2d rtl8139: do not assume TxStatus[] and TxAddr[] are adjacent
Commit afe0a59535 ("rtl8139: support byte
read to TxStatus registers") reused rtl8139_TxStatus_read() for reading
TxAddr registers.  It relies on the fact that TxStatus[] and TxAddr[]
are adjacent.

This causes a gcc warning because the compiler can detect that array
access is out-of-bounds:

  hw/rtl8139.c:2501:27: error: array subscript is above array bounds [-Werror=array-bounds]

This patch refactors the function so that we don't rely on out-of-bounds
accesses.

2ba1d381c2 virtio-pci: change virtio balloon PCI class code
Currently the virtio balloon device, when using the virtio-pci interface
advertises itself with PCI class code MEMORY_RAM.  This is wrong; the
balloon is vaguely related to memory, but is nothing like a PCI memory
device in the meaning of the class code, and this code is not required
or suggested by the virtio PCI specification.

Worse, this patch causes problems on the pseries machine, because the
firmware, seeing this class code, advertises the device as memory in the
device tree, and then a guest kernel bug causes it to see this "memory"
before the real system memory, leading to a crash in early boot.

This patch fixes the problem by removing the bogus PCI class code on the
balloon device.  The backwards compatibility PC machines get new compat
properties so that they don't change.

56f9107e43 qdev: qdev_unplug(): use error_set()
It currently uses qerror_report(), but next commit will convert
the drive_del command to the QAPI and this requires using
error_set().

One particularity of qerror_report() is that it knows when it's
running on monitor context or command-line context and prints the
error message accordingly. error_set() doesn't do this, so we
have to be careful not to drop error messages.

qdev_unplug() has three kinds of usages:

 1. It's called when hot adding a device fails, to undo anything
    that has been done before hitting the error

 2. It's called by function monitor functions like device_del(),
    to unplug a device

 3. It's used by xen_platform.c in a way that doesn't _seem_ to
    be in monitor context

Only item 2 can print an error message to the user, this commit
maintains that.

This patch uses it for dma_bdrv_io() as well.  This involves removing
the DMADirection definition from the #ifdef it was inside, but since that

config.h is not included, there wasn't any reason for it to be there in

02fda01c30 qdev: add blocksize property type
Storage interfaces like virtio-blk can be configured with block size
information so that the guest can take advantage of efficient I/O
request sizes.

According to the SCSI Block Commands (SBC) standard a device's block
size is "almost always greater than one byte and may be a multiple of
512 bytes".  QEMU currently has a 512 byte minimum block size because
the block layer functions work at that granularity.  Furthermore, the
block size should be a power of 2 because QEMU calculates bitmasks from
the value.

Introduce a "blocksize" property type so devices can enforce these
constraints on block size values.  If the constraints are relaxed in the
future then this property can be updated.

Introduce the new PropertyValueNotPowerOf2 QError so QMP clients know
exactly why a block size value was rejected.

da57febfed qdev: give all devices a canonical path
A strong limitation of QOM right now is that unconverted ports
(e.g. all...) do not give a canonical path to devices that are

PROP_PTR with a QOM link for example.

f424d5c4c9 qdev: add children before qdev_init
We want the composition tree to to be in order by the time we call
qdev_init, so that a single set of the toplevel realize property can
propagate all the way down the composition tree.

This is not the case so far.  Unfortunately, this is incompatible
with calling qdev_init in the constructor wrappers for devices,
so for now we need to unattach some devices that are created through
those wrappers.  This will be fixed by removing qdev_init and instead
setting the toplevel realize property after machine init.

67c5322d70 serial: fix retry logic
I'm not sure if the retry logic has ever worked when not using FIFO mode.  I
found this while writing a test case although code inspection confirms it is
definitely broken.

The TSR retry logic will never actually happen because it is guarded by an
'if (s->tsr_rety > 0)' but this is the only place that can ever make the
variable greater than zero.  That effectively makes the retry logic an 'if (0)'.

I believe this is a typo and the intention was >= 0.  Once this is fixed though,
I see double transmits with my test case.  This is because in the non FIFO
case, serial_xmit may get invoked while LSR.THRE is still high because the
character was processed but the retransmit timer was still active.

We can handle this by simply checking for LSR.THRE and returning early.  It's
possible that the FIFO paths also need some attention.

b0f26631bc pl031: switch clock base to rtc_clock
This lets the user specify the desired semantics.  By default, the RTC
will follow adjustments from the host's NTP client, and will remain in
sync when the virtual machine is stopped.  The previous behavior, which
provides determinism with both icount and qtest, remains available with
"-rtc clock=vm".

pl031 supports migration, so we need to convert the time base from
rtc_clock to vm_clock and back for backwards compatibility.  (The
rtc_clock may not be synchronized on the two machines, especially with
savevm/loadvm, so the conversion is needed anyway.  And since any time
base will do, why not pick the one base that is backwards compatible).

Currently QEMU passes the qdev device id to the guest in an ASCII-string
designator in page 0x83.  While this is fine, it does not match what
real hardware does; usually the ASCII-string designator there hosts
another copy of the serial number (there can be other designators,
for example with a world-wide name).  Do the same for QEMU SCSI
disks.

ATAPI does not support VPD pages, so it does not matter there.

This commit is more or less obvious.  What it caused is less obvious:
SCSI CD drives failed to eject under Linux, though for example the
"change" command worked okay.  This happens because of the autoclose
option in the Linux CD-ROM driver.

The actual chain of events is quite complex and somehow involves
udev helpers; the actual command that matters is READ TOC, though
honestly it's not really clear to me how because it should always be
invoked after autoclose, not before.

14dd5faa7e hw/pxa2xx.c: Fix handling of pxa2xx_i2c variable offset within region
The pxa2xx I2C controller can have its registers at an arbitrary offset
within the MemoryRegion it creates. We use this to create two controllers,
one which covers a region of size 0x10000 with registers starting at an
offset 0x1600 into that region, and a second one which covers a region
of size just 0x100 with the registers starting at the base of the region.

The implementation of this offsetting uses two qdev properties, "offset"
(which sets the offset which must be subtracted from the address to
get the offset into the actual register bank) and "size", which is the
size of the MemoryRegion. We were actually using "offset" for two
purposes: firstly the required one of handling the registers not being
at the base of the MemoryRegion, and secondly as a workaround for a
deficiency of QEMU. Until commit 5312bd8b3, if a MemoryRegion was mapped
at a non-page boundary, the address passed into the read and write
functions would be the offset from the start of the page, not the
offset from the start of the MemoryRegion. So when calculating the value
to set the "offset" qdev property we included a rounding to a page
boundary.

Following commit 5312bd8b3 MemoryRegion read/write functions are now
correctly passed the offset from the base of the region, and our
workaround now means we're subtracting too much from addresses, resulting
in warnings like "pxa2xx_i2c_read: Bad register 0xffffff90".
The fix for this is simply to remove the rounding to a page boundary;
this allows us to slightly simplify the expression since
  base - (base & (~region_size)) == base & region_size

The qdev property "offset" itself must remain because it is still
performing its primary job of handling register banks not being at
the base of the MemoryRegion.

27424dcc68 hw/pxa2xx_lcd.c: drop target_phys_addr_t usage in device state
Pxa2xx LCD controller is intended to work with 32-bit bus and it has no knowledge
of system's physical address size, so it should not use target_phys_addr_t in it's
state. Convert three variables in DMAChannel state from target_phys_addr_t to uint32_t,
use VMSTATE_UINT32 instead of VMSTATE_UINTTL for these variables.
We can do this safely because:
1) pxa2xx has 32-bit physical address;
2) rest of the code in file never assumes converted variables to have any size
different from uint32_t;
3) we shouldn't have used VMSTATE_UINTTL in the first place because this macro
is for target_ulong type (which can be different from target_phys_addr_t).

0e4a398ab2 ARM: Remove unnecessary subpage workarounds
In the ARM per-CPU peripherals (GIC, private timers, SCU, etc),
remove workarounds for subpage memory region read/write functions
being passed offsets from the start of the page rather than the
start of the region. Following commit 5312bd8b3 the masking off
of high bits of the address offset is now harmless but unnecessary.

ff71f2e8ca rtl8139: do the network/host communication only in normal operating mode
According the spec, the card works in network/host communication mode only when
both EEM1 and EEM0 are unset in 93C46 Command Register (normal op
mode). So this patch check these bits before trying to receive packets.

As some guest driver (such as linux, see cp_init_hw() in 8139cp.c)
allocate rx ring after the recevier were enabled, this would cause our
emulation codes tries to dma into guest memory when the rx descriptor
is not properly configured. This patch fixes this.

6891710274 pci: fix bridge IO/BASE
commit 5caef97a16010f818ea8b950e2ee24ba876643ad introduced
a regression: we do not make IO base/limit upper 16
bit registers writeable, so we should report a 16 bit
IO range type, not a 32 bit one.
Note that PCI_PREF_RANGE_TYPE_32 is 0x0, but PCI_IO_RANGE_TYPE_32 is 0x1.

In particular, this broke sparc64.

Note: this just reverts to behaviour prior to the commit above.
Making PCI_IO_BASE_UPPER16 and PCI_IO_LIMIT_UPPER16
registers writeable should, and seems to, work just as well, but
as no system seems to actually be interested in 32 bit IO,
let's not make unnecessary changes.

1dc324d20f shpc: standard hot plug controller
This adds support for SHPC interface, as defined by PCI Standard
Hot-Plug Controller and Subsystem Specification, Rev 1.0
http://www.pcisig.com/specifications/conventional/pci_hot_plug/SHPC_10

Only SHPC intergrated with a PCI-to-PCI bridge is supported,
SHPC integrated with a host bridge would need more work.

All main SHPC features are supported:
- MRL sensor
- Attention button
- Attention indicator
- Power indicator

Wake on hotplug and serr generation are stubbed out but unused
as we don't have interfaces to generate these events ATM.

One issue that isn't completely resolved is that qemu currently
expects an "eject" interface, which SHPC does not provide: it merely
removes the power to device and it's up to the user to remove the device
from slot. This patch works around that by ejecting the device
when power is removed and power LED goes off.

8a3d80faf7 pci_bridge: user-friendly default bus name
For a pci bridge device, if we don't override
the name with custom code, the bus will be addressed as
<id>.0, where id is the id specified by the user.

Since PCI Bridge devices have a single bus each, we don't need
the index: address the bus using the parent device name.
This is better since this way users don't care about
our internal bus/device distinctions.

As far as I could see, we only have built-in
bridges at this point which always override the
name. So this change will only affect ioh3420.c.

298a971024 pseries: Configure PCI bridge using properties
Currently, the function spapr_create_phb() uses its parameters to
initialize the correct memory windows for the new PCI Host Bridge
(PHB).  This is not the way things are supposed to be done with qdevs,
and means you can't create extra PHBs easily using -device.

Since pSeries machines can and do have many PHBs with various
configurations, this is a real limitation, not just a theoretical.
This patch, therefore, alters the PHB initialization code to use qdev
properties to set these parameters of the new bridge, moving most of
the code from spapr_create_phb() to spapr_phb_init().

While we're at it, we change the naming of each PCI bus and its
associated memory regions to be less arbitrary and make it easier to
relate the guest and qemu views of memory to each other.

d07fee7e8a pseries: Add support for level interrupts to XICS
The pseries "xics" interrupt controller, like most interrupt
controllers can support both message (i.e. edge sensitive) interrupts
and level sensitive interrupts, but it needs to know which are which.

When I implemented the xics emulation for qemu, the only devices we
supported were the PAPR virtual IO devices.  These devices only use
message interrupts, so they were the only ones I implemented in xics.

Since then, however, we have added support for PCI devices, which use
level sensitive interrupts.  It turns out the message interrupt logic
still actually works most of the time for these, but there are
circumstances where we can lost interrupts due to the incorrect
interrupt logic.

This patch, therefore, implements the correct xics level-sensitive
interrupt logic.  The type of the interrupt is set when a device
allocates a new xics interrupt.

9512e4a9ed kvmvapic: align start address as well as size
The kvmvapic code remaps a section of ROM as RAM to allow the guest to
maintain state there.  It is careful to align the section size to a page
boundary, to avoid creating subpages, but neglects to do the same for
the start address.  These leads to an assert later on when the memory
core tries to create a page which is half RAM and half ROM.

Fix by aligning the start address to a page boundary.

This can be triggered by running qemu-system-x86_64 -enable-kvm -vga none.

03f48b0797 kvmclock: Always register type
Currently, the "kvmclock" type is only registered when kvm_enabled().

This breaks when moving type registration to before command line
parsing (so that QOM types can be used for CPU and machine).

Since the QOM classes are lazy-initialized anyway and kvmclock_create()
has another kvm_enabled() check, simply drop the KVM check in
kvmclock_register_types().

kvm-i8259, kvm-apic and kvm-ioapic do not suffer from such a check.

86e18cae20 usb-ohci: DMA writeback bug fixes
This patch fixes two bugs in the OHCI device where the device writes
back data to system memory that should be exclusively under the
control of the guest side driver.

In OHCI specification Section 5.2.7, it mentioned "In all cases, Host
Controller Driver is responsible for the insertion and removal of all
Endpoint Descriptors in the various Host Controller Endpoint
Descriptor lists".  In the ohci_frame_boundary(), ohci_put_hcca()
writes the entire hcca back including the interrupt ED lists which
should be under driver control. This violates the specification and
can race with a host driver updating that list at the same time.

In the OHCI Spec Section 4.6, Transfer Descriptor Queue Processing, it
mentioned "Since the TD pointed to by TailP is not accessed by the HC,
the Host Controller Driver can initialize that TD and link at least
one other to it without creating a coherency or synchronization
problem".  While the function ohci_put_ed() writes the entire endpoint
descriptor back including the TailP which should under driver
control. This violate the specification and can race with a host
driver updating the TD list at the same time.

In each case the solution is to make sure we don't write data which is
under driver control.

d61000a8b1 usb: add USB_RET_IOERROR
We already have USB_RET_NAK, but that means that a device does not want
to send/receive right now. But with host / network redirection we can
actually have a transaction fail due to some io error, rather then ie
the device just not having any data atm.

This patch adds a new error code named USB_RET_IOERROR for this, and uses
it were appropriate.

Notes:
-Currently all usb-controllers handle this the same as NODEV, but that
 may change in the future, OHCI could indicate a CRC error instead for example.
-This patch does not touch hw/usb-musb.c, that is because the code in there
 handles STALL and NAK specially and has a if status < 0 generic catch all

553a6a59f6 usb-ehci: Fix and simplify nakcnt handling
The nakcnt code in ehci_execute_complete() marked transactions as finished
when a packet completed with a result of USB_RET_NAK, but USB_RET_NAK
means that the device cannot receive / send data at that time and that
the transaction should be retried later, which is also what the usb-uhci
and usb-ohci code does.

Note that there already was some special code in place to handle this
for interrupt endpoints in the form of doing a return from
ehci_execute_complete() when reload == 0, but that for bulk transactions
this was not handled correctly (where as for example the usb-ccid device does
return USB_RET_NAK for bulk packets).

Besides that the code in ehci_execute_complete() decrement nakcnt by 1
on a packet result of USB_RET_NAK, but
-since the transaction got marked as finished,
 nakcnt would never be decremented again
-there is no code checking for nakcnt becoming 0
-there is no use in re-trying the transaction within the same usb frame /
 usb-ehci frame-timer call, since the status of emulated devices won't change
 as long as the usb-ehci frame-timer is running
So we should simply set the nakcnt to 0 when we get a USB_RET_NAK, thus
claiming that we've tried reload times (or as many times as possible if
reload is 0).

Besides the code in ehci_execute_complete() handling USB_RET_NAK there
was also code handling it in ehci_state_executing(), which calls
ehci_execute_complete(), and then does its own handling on top of the handling
in ehci_execute_complete(), this code would decrement nakcnt *again* (if not
already 0), or restore the reload value (which was never changed) on success.

Since the double decrement was wrong to begin with, and is no longer needed
now that we set nakcnt directly to 0 on USB_RET_NAK, and the restore of reload
is not needed either, this patch simply removes all nakcnt handling from
ehci_state_executing().

aa73fcdcc1 usb-ehci: Remove dead nakcnt code
This patch removes 2 bits of dead nakcnt code:

1) usb_ehci_execute calls ehci_qh_do_overlay which does:
nakcnt = reload;
and then has a block of code which is conditional on:
if (reload && !nakcnt) {
which ofcourse is never true now as nakcnt == reload.

2) ehci_state_fetchqh does:
nakcnt = reload;
but before nakcnt is ever used ehci_state_fetchqh is always followed
by a ehci_qh_do_overlay call which also does:
nakcnt = reload;
So doing this from ehci_state_fetchqh is redundant.

Since we don't have any hardware level errors (and in case of redirection

4be23939ab usb-ehci: Drop cached qhs when the doorbell gets rung
The purpose of the IAAD bit / the doorbell is to make the ehci controller
forget about cached qhs, this is mainly used when cancelling transactions,
the qh is unlinked from the async schedule and then the doorbell gets rung,
once the doorbell is acked by the controller the hcd knows that the qh is
no longer in use and that it can do something else with the memory, such
as re-use it for a new qh! But we keep our struct representing this qh around
for circa 250 ms. This allows for a (mightily large) race window where the
following could happen:
-hcd submits a qh at address 0xdeadbeef
-our ehci code sees the qh, sends a request to a usb-device, gets a result
 of USB_RET_ASYNC, sets the async_state of the qh to EHCI_ASYNC_INFLIGHT
-hcd unlinks the qh at address 0xdeadbeef
-hcd rings the doorbell, wait for us to ack it
-hcd re-uses the qh at address 0xdeadbeef
-our ehci code sees the qh, looks in the async_queue, sees there already is
 a qh at address 0xdeadbeef there with async_state of EHCI_ASYNC_INFLIGHT,
 does nothing
-the *original* (which the hcd thinks it has cancelled) transaction finishes
-our ehci code sees the qh on yet another pass through the async list,
 looks in the async_queue, sees there already is a qh at address 0xdeadbeef
 there with async_state of EHCI_ASYNC_COMPLETED, and finished the transaction
 with the results of the *original* transaction.

Not good (tm), this patch fixes this race by removing all qhs which have not
been seen during the last cycle through the async list immidiately when the
doorbell is rung.

Note this patch does not fix any actually observed problem, but upon
reading of the EHCI spec it became apparent to me that the above race could
happen and the usb-ehci behavior from before this patch is not good.

7bce354e14 usb-ehci: always call ehci_queues_rip_unused for period queues
Before this patch USB 2 devices with interrupt endpoints were not working
properly. The problem is that to avoid loops we stop processing as soon
as we encounter a queue-head (qh) we've already seen since qhs can be linked
in a circular fashion, this is tracked by the seen flag in our qh struct.

The resetting of the seen flag is done from ehci_queues_rip_unused which
before this patch was only called when executing the statemachine for the
async schedule.

But packets for interrupt endpoints are part of the periodic schedule! So what
would happen is that when there were no ctrl or bulk packets for a USB 2
device with an interrupt endpoint, the async schedule would become non
active, then ehci_queues_rip_unused would no longer get called and when
processing the qhs for the interrupt endpoints from the periodic schedule
their seen bit would still be 1 and they would be skipped.

This provides the required user space stubs to enable the in-kernel
i8254 emulation of KVM.

The in-kernel model supports lost tick compensation according to the
"delay" policy. This is enabled by default and can be switched off via a
device property.

Depending on the feature set of the host kernel (before 2.6.32), we may
have to disable the HPET or lack sound output from the PC speaker.

Same as for the APIC: To enable migration between accelerated and

to the the next_transition_time field.

1edb493490 s390: Rework kernel loading: supports elf and newer kernels
This reworks the image loading on s390.

Newer kernels will not always have a 0dd0 (basr 13,0) at address 0x10000.
We must not rely on specific code at certain  addresses. This check was
introduced to warn users that tried to load vmlinux, since ELF loading
was not supported. Lets wire that up. If elf loading fails, we assume
that this is a standard kernel image and load that via load_image_targphys.
This patch also changes all other users of load_image to
load_image_targphys to be consistent. (the elf loader registers the kernel
as rom).

(realview-eb board specific device encapsulating CPU and some
extra interrupt controllers) -- the num-irq property was defined
on the wrong device and the mpcore_rirq_properties were defined
as offsets in the wrong structure. The effect was that the
realview-eb-mpcore machine would abort on startup trying to

50c1e1491e memory: support stateless memory listeners
Current memory listeners are incremental; that is, they are expected to
maintain their own state, and receive callbacks for changes to that state.

This patch adds support for stateless listeners; these work by receiving
a ->begin() callback (which tells them that new state is coming), a
sequence of ->region_add() and ->region_nop() callbacks, and then a
->commit() callback which signifies the end of the new state.  They should
ignore ->region_del() callbacks.

6f2b175a09 qxl: add optinal 64bit vram bar
This patch adds an 64bit pci bar for vram.  It is turned off by default.
It can be enabled by setting the size of the 64bit bar to be larger than
the 32bit bar.  Both 32bit and 64bit bar refer to the same memory.  Only
the first part of the memory is available via 32bit bar.

The intention is to allow large vram sizes for 64bit guests, by allowing
the vram bar being mapped above 4G, so we don't have to squeeze it into
the pci I/O window below 4G.

With vram_size_mb=16 and vram64_size_mb=256 it looks like this:

Resolve this by passing a bus reference to the usbdevice_init handler

df7871851e usb-ehci: Handle ISO packets failing with an error other then NAK
Before this patch the ehci code was not checking for any other errors other
then USB_RET_NAK. This causes 2 problems:
1) Other errors are not reported to the guest.
2) When transactions with the ITD_XACT_IOC bit set completing with another
   error would not result in USBSTS_INT getting set.

I hit this problem when unplugging devices while iso data was streaming from
the device to the guest. When this happens it takes a while for the guest to
process the unplugging and remove ISO transactions from the ehci schedule, in
the mean time these transactions would complete with a result of USB_RET_NODEV,
which was not handled. This lead to the Linux guest's usb subsystem "hanging",
that is it would no longer see new usb devices getting plugged in and running
for example lsusb would lead to a stuck (D state) lsusb process. This patch
fixes this.

that corresponds to dev->config being NULL (it defaults to NULL and is
reset whenever a SET_CONFIGURATION with value 0, or attachment). I
implemented it to correspond with the state before
ed5a83ddd8, the commit moving SET_STATUS
to usb-desc; if dev->config is not set we return whatever is in the
first configuration.

The behavior of USB_REQ_GET_CONFIGURATION is also undefined before any
SET_CONFIGURATION, but here we just return 0 (same as specified for the
Address state).

A win7 guest failed to initialize the device before this patch,
segfaulting when GET_STATUS was called with dev->config == NULL. With
this patch the passthrough device still doesn't work but the failure is
unrelated.

aa0568ff25 usb-ehci: sanity-check iso xfers
This patch adds a sanity check to itd processing to make sure the
endpoint addressed by the guest is actually an iso endpoint.  Also

81fb6f1504 qxl: make qxl_render_update async
RHBZ# 747011

Removes the last user of QXL_SYNC when using update drivers that use the
_ASYNC io ports.

The last user is qxl_render_update, it is called both by qxl_hw_update
which is the vga_hw_update_ptr passed to graphic_console_init, and by
qxl_hw_screen_dump.

At the same time the QXLRect area being passed to the red_worker thread
is passed as a copy, as part of the QXLCookie.

The implementation uses interface_update_area_complete with a bh to make
sure dpy_update and qxl_flip are called from the io thread, otherwise
the vga->ds->surface.data can change under our feet.

With this patch sdl+spice works fine. But spice by itself doesn't
produce the expected screendumps unless repeated a few times, due to
ppm_save being called before update_area (rendering done in spice server
thread) having a chance to complete. Fixed by next patch, but see commit
message for problem introduced by it.
