06a1307379 virtio-pci: add device_unplugged callback
This fixes a crash in hot-unplug of virtio-pci devices behind a PCIe
switch.  The crash happens because the ioeventfd is still set whent the
child is destroyed (destruction happens in postorder).  Then the proxy
tries to unset to ioeventfd, but the virtqueue structure that holds the
EventNotifier has been trashed in the meanwhile.  kvm_set_ioeventfd_pio
does not expect failure and aborts.

The fix is simply to move parts of uninitialization to a new
device_unplugged callback, which is called before the child is destroyed.

5e96f5d2f8 virtio-bus: cleanup plug/unplug interface
Right now we have these pairs:

- virtio_bus_plug_device/virtio_bus_destroy_device.  The first
  takes a VirtIODevice, the second takes a VirtioBusState

- device_plugged/device_unplug callbacks in the VirtioBusClass
  (here it's just the naming that is inconsistent)

- virtio_bus_destroy_device is not called by anyone (and since
  it calls qdev_free, it would be called by the proxies---but
  then the callback is useless since the proxies can do whatever
  they want before calling virtio_bus_destroy_device)

And there is a k->init but no k->exit, hence virtio_device_exit is
overwritten by subclasses (except virtio-9p).  This cleans it up by:

- renaming the device_unplug callback to device_unplugged

- renaming virtio_bus_plug_device to virtio_bus_device_plugged,
  matching the callback name

- renaming virtio_bus_destroy_device to virtio_bus_device_unplugged,
  removing the qdev_free, making it take a VirtIODevice and calling it
  from virtio_device_exit

- adding a k->exit callback

virtio_device_exit is still overwritten, the next patches will fix that.

0b81c1ef5c virtio-ccw: move virtio_ccw_stop_ioeventfd to virtio_ccw_busdev_unplug
Similar to the PCI bug that prompted these patches, virtio-ccw will
segfault after the reworking of hotplug/hot-unplug.  Prepare for
this by moving virtio_ccw_stop_ioeventfd to before the freeing
of the proxy device.

A better place for this could be the device_unplugged callback
for the virtio-ccw bus.  However, we do not yet have a callback
that works: this patch avoids the problem while leaving the tree
bisectable.

cae2e5562c virtio-net: don't update mac_table in error state
mac_table was always cleaned up first in handling
VIRTIO_NET_CTRL_MAC_TABLE_SET command, and we din't recover
mac_table content in error state, it's not correct.

This patch makes all the changes in temporal variables,
only update the real mac_table if everything is ok.
We won't change mac_table in error state, so rxfilter
notification isn't needed.

This patch also fixed same problame in
 http://lists.nongnu.org/archive/html/qemu-devel/2013-11/msg01188.html
 (not merge)

I will send patch for virtio spec to clarifying this change.

d97e773081 scsi-disk: fix VERIFY emulation
VERIFY emulation was completely botched (and remained botched through
all the refactorings).  The command must be emulated both in check-medium
mode (BYTCHK=00, which we implement by doing nothing) and in check-bytes
mode (which we do not implement yet).  Unlike WRITE AND VERIFY (which we
treat simply as WRITE with FUA bit set), VERIFY cannot be handled like
READ.  In fact the device is _receiving_ data for VERIFY, not _sending_
it like READ.

d2aa90cda8 vfio-pci updates include:
- Update linux-headers to include KVM-VFIO device support
  - Enable QEMU support for KVM-VFIO device
  - Additional Nvidia x-vga quirk to ACK MSI interrupts
  - Debug options to disable MSI/X KVM acceleration
  - Fix to cleanup MSI-X vectors on shutdown and avoid IRQ route leaks
 
 The KVM-VFIO device support enables KVM to manage how it handles
 coherency instructions in the presence of non-coherent I/O.  Dave
 Airlie had noted that the Nvidia MSI ACK support here may just be
 scratching the surface, but it's better than what we have now and
 it's only enabled via the x-vga option, so I'm willing to add since
 it does enable some users.

3e40ba0faf vfio-pci: Release all MSI-X vectors when disabled
We were relying on msix_unset_vector_notifiers() to release all the
vectors when we disable MSI-X, but this only happens when MSI-X is
still enabled on the device.  Perform further cleanup by releasing
any remaining vectors listed as in-use after this call.  This caused
a leak of IRQ routes on hotplug depending on how the guest OS prepared
the device for removal.

96eeeba0db vfio-pci: Fix Nvidia MSI ACK through 0x88000 quirk
When MSI is enabled on Nvidia GeForce cards the driver seems to
acknowledge the interrupt by writing a 0xff byte to the MSI capability
ID register using the PCI config space mirror at offset 0x88000 from
BAR0.  Without this, the device will only fire a single interrupt.
VFIO handles the PCI capability ID/next registers as virtual w/o write
support, so any write through config space is currently dropped.  Add
a check for this and allow the write through the BAR window.  The
registers are read-only anyway.

84f94a9a82 scsi-disk: correctly implement WRITE SAME
Fetch the data to be written from the input buffer.  If it is all zeroes,
we can use the write_zeroes call (possibly with the new MAY_UNMAP flag).
Otherwise, do as many write cycles as needed, writing 512k at a time.

Strictly speaking, this is still incorrect because a zero cluster should
only be written if the MAY_UNMAP flag is set.  But this is a bug in qcow2
and the other formats, not in the SCSI code.

49cfa2fdc9 uas: Fix response iu struct definition
This patch mirrors a patch to the Linux uas kernel driver which I've just
submitted. It looks like the qemu uas struct definitions were taken from
the Linux kernel driver, and have inherited the same mistake.

Besides fixing the response iu struct, the patch also drops the add_info
parameter from the usb_uas_queue_response() function, it is always 0 anyways,
and expressing 3 zero-bytes as a function argument is a bit hard.

Below is the long explanation for this change taken from the kernel commit:

The response iu struct before this patch has a size of 7 bytes, which is weird
since all other iu-s are explictly padded to a multiple of 4 bytes.

Submitting a 7 byte bulk transfer to the status endpoint of a real uasp device
when expecting a response iu results in an USB babble error, as the device
actually sends 8 bytes.

Up on closer reading of the UAS spec:
http://www.t10.org/cgi-bin/ac.pl?t=f&f=uas2r00.pdf

The reason for this becomes clear, the 2 entries in "Table 17 — RESPONSE IU"
are numbered 4 and 6, looking at other iu definitions in the spec, esp.
multi-byte fields, this indicates that the ADDITIONAL RESPONSE INFORMATION
field is not a 2 byte field as one might assume at a first look, but is
a multi-byte field containing 3 bytes.

This also aligns with the SCSI Architecture Model 4 spec, which UAS is based
on which states in paragraph "7.1 Task management function procedure calls"
that the "Additional Response Information" output argument for a Task
management function procedure call is 3 bytes.

Last but not least I've verified this by sending a logical unit reset task
management call with an invalid lun to an actual uasp device, and received
back a response-iu with byte 6 being 0, and byte 7 being 9, which is the
responce code for an invalid iu, which confirms that the response code is
being reported in byte 7 of the response iu rather then in byte 6.

f1f8bc218a xhci: add support for suspend/resume
The OS can ask the xhci controller to save and restore its
internal state, which is used by the OS when the system is
suspended and resumed.

This patch handles writes to the save + restore bits in the
command register.  Only thing it does is updating the
restore error bit in the status register to signal an error
on restore.  The guest OS should do a full reinitialization
after resume then.

This is the minimal patch which gets S3 going with xhci.
Implementing full save/restore support is TBD.

de9de157fb xhci: Add a few missing checks for disconnected devices
One of the reworks of qemu's usb core made changes to usb-port's disconnect
handling. Now ports with a device will always have a non 0 dev member, but
if the device is not attached (which is possible with usb redirection),
dev->attached will be 0.

So supplement all checks for dev to also check dev->attached, and add an
extra check in a path where a device check was completely missing.

This fixes various crashes (asserts triggering) I've been seeing when xhci
attached usb devices get disconnected at the wrong time.

84dc96e1e5 PPC: BookE: Make FIT/WDT timers at best millisecond grained
The default granularity for the FIT timer on 440 is on every 0x1000th
transition of TB from 0 to 1. Translated that means 48828 times a second.

Since interrupts are quite expensive for 440 and we don't really care
about the accuracy of the FIT to that significance, let's force FIT and
WDT to at best millisecond granularity.

This basically restores behavior as it was in QEMU 1.6, where timers
could only deal with millisecond granularities at all.

This patch greatly improves performance with the 440 target and restores
roughly the same performance level that QEMU 1.6 had for me.

455df3f323 PPC: Make BookE FIT/WDT timers more lazy
Today we fire FIT and WDT timer events every time the respective bit
position in TB flips from 0 -> 1.

However, there is no need to do this if the end result would be that
we're changing a TSR bit that is set to 1 to 1 again. No guest visible
change would have occured.

So whenever we see that the TSR bit to our timer is already set, don't
even bother to update the timer that would potentially fire it off.

However, we do need to make sure that we update our timer that notifies
us of the TB flip when the respective TSR bit gets unset. In that case
we do care about the flip and need to notify the guest again. So add
a callback into our timer handlers when TSR bits get unset.

This improves performance for me when the guest is busy processing things.

30c367ed44 qdev-properties-system.c: Allow vlan or netdev for -device, not both
It is currently possible to specify things like:
	-device e1000,netdev=foo,vlan=1
With this usage, whichever argument was specified last (vlan or netdev)
overwrites what was previousely set and results in a non-working
configuration.  Even worse, when used with multiqueue devices,
it causes a segmentation fault on exit in qemu_free_net_client.

That patch treates the above command line options as invalid and
generates an error at start-up.

b6a06e72ef mips jazz: do not raise data bus exception when accessing invalid addresses
MIPS Jazz chipset doesn't seem to raise data bus exceptions on invalid accesses.
However, there is no easy way to prevent them. Creating a big memory region
for the whole address space doesn't prevent memory core to directly call
unassigned_mem_read/write which in turn call cpu->do_unassigned_access,
which (for MIPS CPU) raise an data bus exception.

This fixes a MIPS Jazz regression introduced in c658b94f6e.

7839ff593b pc: get rid of builtin pvpanic for "-M pc-1.5"
This causes two slight backwards-incompatibilities between "-M pc-1.5"
and 1.5's "-M pc":

(1) a fw_cfg file is removed with this patch.  This is only a problem
if migration stops the virtual machine exactly during fw_cfg enumeration.

(2) after migration, a VM created without an explicit "-device pvpanic"
will stop reporting panics to management.

The first problem only occurs if migration is done at a very, very
early point (and I'm not sure it can happen in practice for reasonable-size
VMs, since it will likely take more time to send the RAM to destination,
than it will take for BIOS to scan fw_cfg).

The second problem only occurs if the guest panics _and_ has a guest
driver _and_ management knows to look at the crash event, so it is
mostly theoretical at this point in time.

Thus keep the code simple, and pretend it was never broken.

da87dd7bd7 sun4m: Add FCode ROM for TCX framebuffer
Upstream OpenBIOS now implements SBus probing in order to determine the
contents of a physical bus slot, which is required to allow OpenBIOS to
identify the framebuffer without help from the fw_cfg interface.

SBus probing works by detecting the presence of an FCode program
(effectively tokenised Forth) at the base address of each slot, and if
present executes it so that it creates its own device node in the
OpenBIOS device tree.

The FCode ROM is generated as part of the OpenBIOS build and should
generally be updated at the same time.

376827d489 s390x: fix flat file load on 32 bit systems
pc-bios/s390-zipl.rom is a flat image so it's expected that
loading it as elf will fail.
It should fall back on loading a flat file, but doesn't
on 32 bit systems, instead it fails printing:
    qemu: hardware error: could not load bootloader 's390-zipl.rom'

The result is boot failure.

The reason is that a 64 bit unsigned interger which is set
to -1 on error is compared to -1UL which on a 32 bit system
with gcc is a 32 bit unsigned interger.
Since both are unsigned, no sign extension takes place and
comparison evaluates to non-equal.

There's no reason to do clever tricks: all functions
we call actually return int so just use int.
And then we can use == -1 everywhere, consistently.

90d131fb65 Revert "e1000/rtl8139: update HMP NIC when every bit is written"
This reverts commit cd5be5829c.
Digging into hardware specs shows this does not
actually make QEMU behave more like hardware:

There are valid arguments backed by the spec to indicate why the version
of e1000 prior to cd5be582 was more correct: the high byte actually
includes a valid bit, this is why all guests write it last.

For rtl8139 there's actually a separate undocumented valid bit, but we
don't implement it yet.

To summarize all the drivers we know about behave in one way
that allows us to make an assumption about write order and avoid
spurious, incorrect mac address updates to the monitor.

Let's stick to the tried heuristic for 1.7 and
possibly revisit for 1.8.

to get table size in bytes.

25a666d2ec pci-assign: Fix error_report of pci-stub message
Using multiple calls to error_report here means every line is
prefaced with the (potentially long) pci-assign command line
arguments.

Use a single error_printf to preserve the intended formatting.
Since this code path is always preceded by an error_report call,
we don't lose the command line reporting.

0fbf50b6ec Revert "hw/pci: partially handle pci master abort"
This reverts commit a53ae8e934.

The patch being reverted introduced a low-priority memory region
covering all 64 bit pci address space.  This exposed the following bugs
elsewhere in the code:
 1. Some memory regions have INT64_MAX size, where the
    intent was all 64 bit address space.
    This results in a sub-page region, should be UINT64_MAX.
 2. page table rendering in exec.c ignores physical address bits
    above TARGET_PHYS_ADDR_SPACE_BITS.
    Access outside this range (e.g. from device DMA, or gdb stub)
    ends up with a wrong region.  Registering a region outside this
    range leads to page table corruption.
 3. Some regions overlap PCI hole and have same priority.
    This only works as long as no device uses the overlapping address.

It doesn't look like we can resolve all issues in time for 1.7.
Let's fix the bugs first and apply afterwards for 1.8.

fe1479aa25 loader: drop return value for rom_add_blob_fixed
rom_add_blob never fails, and neither does rom_add_blob_fixed,
so there's no need to return value from it.

In fact, rom_add_blob_fixed was erroneously returning -1 unconditionally
which made the only system that checked the return value -M bamboo fail
to start.

Drop the return value and drop checks from ppc440_bamboo to
fix this failure.

04c7d8b8de Fix pc migration from qemu <= 1.5
The following commit introduced a migration incompatibility:

commit 568f0690fd
Author: David Gibson <david@gibson.dropbear.id.au>
Date:   Thu Jun 6 18:48:49 2013 +1000

    pci: Replace pci_find_domain() with more general pci_root_bus_path()

The issue is that i440fx savevm idstr went from 0000:00:00.0/I440FX to
0000:00.0/I440FX. Unfortunately we are stuck with the breakage for
1.6 machine types.

Add a compat property to maintain the busted idstr for the 1.6 machine
types, but revert to the old style format for 1.7+, and <= 1.5.

Tested with migration from qemu 1.5, qemu 1.6, and qemu.git.

cd5be5829c e1000/rtl8139: update HMP NIC when every bit is written
We currently just update the HMP NIC info when the last bit of macaddr
is written. This assumes that guest driver will write all the macaddr
from bit 0 to bit 5 when it changes the macaddr, this is the current
behavior of linux driver (e1000/rtl8139cp), but we can't do this
assumption.

The macaddr that is used for rx-filter will be updated when every bit
is changed. This patch updates the e1000/rtl8139 nic to update HMP NIC
info when every bit is changed. It will be same as virtio-net.

02a5c4c974 qdev: Drop misleading qdev_free() function
The qdev_free() function name is misleading since all the function does
is unlink the device from its parent.  The device is not necessarily
freed.

The device will be freed when its QObject refcount reaches zero.  It is
usual for the parent (bus) to hold the final reference but there are
cases where something else holds a reference so "free" is a misleading
name.

Call object_unparent(obj) directly instead of having a qdev wrapper
function.

Format is simliar to the FW_CFG_E820_TABLE, it is a simple list of

b86160555f integrator: fix Linux boot failure by emulating dbg region
Commit 9b8c69243 (since reverted) broke the ability to boot the kernel
as the value returned by unassigned_mem_read returned non-zero and left
the kernel looping forever waiting for it to change (see
integrator_led_set in the kernel code).

Relying on a varying implementation detail is incorrect anyway so this
introduces a basic stub of a memory region for the debug/LED section
on the integrator board.

8464b273d6 ahci: fix win7 hang on boot
When AHCI executes an asynchronous IDE command, it checked DRDY without
checking either DRQ or BSY.  This sometimes caused interrupt to be sent
before command is actually completed.

This resulted in a race condition: if guest then managed to access the
device before command has completed, it would hang waiting for an
interrupt.
This was observed with windows 7 guests.

To fix, check for DRQ or BSY in additiona to DRDY, if set,
the command is asynchronous so delay the interrupt until
asynchronous done callback is invoked.

3bbf37f269 spapr: Use DeviceClass::fw_name for device tree CPU node
Instead of relying on cpu_model, obtain the device tree node label
per CPU. Use DeviceClass::fw_name as source.

Whenever DeviceClass::fw_name is unknown, default to "PowerPC,UNKNOWN".

As a consequence, spapr_fixup_cpu_dt() can operate on each CPU's fw_name,
obsoleting sPAPREnvironment::cpu_model, and spapr_create_fdt_skel() can
drop its cpu_model argument.

11ad93f681 xics-kvm: Support for in-kernel XICS interrupt controller
Recent (host) kernels support emulating the PAPR defined "XICS" interrupt
controller system within KVM.  This patch allows qemu to initialize and
configure the in-kernel XICS, and keep its state in sync with qemu's XICS
state as necessary.

This should give considerable performance improvements.  e.g. on a simple
IPI ping-pong test between hardware threads, using qemu XICS gives us
around 5,000 irqs/second, whereas the in-kernel XICS gives us around
70,000 irqs/s on the same hardware configuration.

5a3d7b23ba xics: split to xics and xics-common
The upcoming XICS-KVM support will use bits of emulated XICS code.
So this introduces new level of hierarchy - "xics-common" class. Both
emulated XICS and XICS-KVM will inherit from it and override class
callbacks when required.

The new "xics-common" class implements:
1. replaces static "nr_irqs" and "nr_servers" properties with
the dynamic ones and adds callbacks to be executed when properties
are set.
2. xics_cpu_setup() callback renamed to xics_common_cpu_setup() as
it is a common part for both XICS'es
3. xics_reset() renamed to xics_common_reset() for the same reason.

The emulated XICS changes:
1. the part of xics_realize() which creates ICPs is moved to
the "nr_servers" property callback as realize() is too late to
create/initialize devices and instance_init() is too early to create
devices as the number of child devices comes via the "nr_servers"
property.
2. added ics_initfn() which does a little part of what xics_realize() did.
