Kővágó, Zoltán 06ac27f683 audio: remove LOG_TO_MONITOR along with default_mon
Setting QEMU_AUDIO_LOG_TO_MONITOR=1 can crash qemu (if qemu tries to log
to the monitor before it's being initialized), and also nothing else in
qemu logs to the monitor.

This log to monitor feature was the last thing that used the default_mon
variable, so I removed it too (as using it can cause problems).

Alexander Graf 8be656b87c linux-user: Allocate thunk size dynamically
We store all struct types in an array of static size without ever
checking whether we overrun it. Of course some day someone (like me
in another, ancient ALSA enabling patch set) will run into the limit
without realizing it.

So let's make the allocation dynamic. We already know the number of
structs that we want to allocate, so we only need to pass the variable
into the respective piece of code.

Also, to ensure we don't accidently overwrite random memory, add some
asserts to sanity check whether a thunk is actually part of our array.

Kevin Wolf bddcec3745 block: Add BlockDriverState.inherits_from
Currently, the block layer assumes that any block node can have only one
parent, and if it has a parent, that it inherits some options/flags from
this parent.

This is not true any more: With references used in block device
creation, a single node can be used by multiple parents, or it can be
created separately and not inherit flags from any parent.

To handle reopens correctly, a node must know from which parent it
inherited options. This patch adds the information to BlockDriverState.

Kevin Wolf 6e93e7c41f block: Add list of children to BlockDriverState
This allows iterating over all children of a given BDS, not only
including bs->file and bs->backing_hd, but also driver-specific
ones like VMDK extents or Quorum children.

For bdrv_swap(), the list of children of the swapped BDS stays at that
BDS (because that's where the pointers stay as well). The list head
moves and pointers to it must be fixed up therefore.

The list of children in the parent of the swapped BDS is not affected by
the swap. The contents of the BDS objects is swapped, so the existing
pointer in the parent automatically points to the newly swapped in BDS.

Kevin Wolf 7990d2c99c qdict: Add qdict_{set,copy}_default()
In the block layer functions that determine options for a child block
device, it's a common pattern to either copy options from the parent's
options or to set a default string if the option isn't explicitly set
yet for the child. Provide convenience functions so that it becomes a
one-liner for each option.

Kevin Wolf bd50530a9f qdict: Add qdict_array_entries()
This counts the entries in a flattened array in a QDict without
actually splitting the QDict into a QList.

bdrv_open_image() doesn't take a QList, but rather a QDict and a key
prefix string, so this is more convenient for block drivers which have a
dynamically sized list of child nodes (e.g. Quorum) and are to be
converted to using bdrv_open_image() as the standard interface for
opening child nodes.

Alberto Garcia db6283385c throttle: acquire the ThrottleGroup lock in bdrv_swap()
bdrv_swap() touches the fields of a BlockDriverState that are
protected by the ThrottleGroup lock. Although those fields end up in
their original place, they are temporarily swapped in the process,
so there's a chance that an operation on a member of the same group
happening on a different thread can try to use them.

Alberto Garcia 76f4afb40f throttle: Add throttle group support
The throttle group support use a cooperative round robin scheduling
algorithm.

The principles of the algorithm are simple:
- Each BDS of the group is used as a token in a circular way.
- The active BDS computes if a wait must be done and arms the right
  timer.
- If a wait must be done the token timer will be armed so the token
  will become the next active BDS.

As a consequence the ThrottleState will be accessed by multiple aio

Timers are tied to their aio context so they must go out of the

Dr. David Alan Gilbert f68945d42b Add a protective section footer
Badly formatted migration streams can go undetected or produce
misleading errors due to a lock of checking at the end of sections.
In particular a section that adds an extra 0x00 at the end
causes what looks like a normal end of stream and thus doesn't produce
any errors, and something that ends in a 0x01..0x04 kind of look
like real section headers and then fail when the section parser tries
to figure out which section they are.  This is made worse by the
choice of 0x00..0x04 being small numbers that are particularly common
in normal section data.

This patch adds a section footer consisting of a marker (0x7e - ~)
followed by the section-id that was also sent in the header.  If
they mismatch then it throws an error explaining which section was
being loaded.

  it is just a VMStateDescription)
- Adjust the whole tree, moving the needed function to the corresponding

Michael S. Tsirkin adfb743c90 virtio: add modern config accessors
virtio 1.0 defines config space as LE,
as opposed to pre-1.0 which was native endian.

Add API for transports to execute word/dword accesses in
little endian format - will be useful for mmio
and pci (byte access is also wrapped, for completeness).

For simplicity, we still keep config in host native
endian format, byteswap to LE on guest access.

When the argument is zero, it doesn't stop, and returns the callback's

The two callers that pass zero could just as well pass one:

Paolo Bonzini 3bbf572345 atomics: add explicit compiler fence in __atomic memory barriers
__atomic_thread_fence does not include a compiler barrier; in the
C++11 memory model, fences take effect in combination with other
atomic operations.  GCC implements this by making __atomic_load and
__atomic_store access memory as if the pointer was volatile, and
leaves no trace whatsoever of acquire and release fences in the
compiler's intermediate representation.

In QEMU, we want memory barriers to act on all memory, but at the same
time we would like to use __atomic_thread_fence for portability reasons.
Add compiler barriers manually around the __atomic_thread_fence.

This region is exported at /machine/smram.  It is "empty" if
SMRAME=0 and points to SMRAM if SMRAME=1.  The CPU will

While touching nearby code, the existing memory region setup was
slightly inconsistent.  The smram_region is *disabled* in order to open
SMRAM (because the smram_region shows the low VRAM instead of the RAM
at 0xa0000).  Because SMRAM is closed at startup, the smram_region must
be enabled when creating the i440fx or q35 devices.

Paolo Bonzini e87f7778b6 exec: only check relevant bitmaps for cleanliness
Most of the time, not all bitmaps have to be marked as dirty;
do not do anything if the interesting ones are already dirty.
Previously, any clean bitmap would have cause all the bitmaps to be
marked dirty.

In fact, unless running TCG most of the time bitmap operations need
not be done at all, because memory_region_is_logging returns zero.
In this case, skip the call to cpu_physical_memory_range_includes_clean
altogether as well.

With this patch, cpu_physical_memory_set_dirty_range is called
unconditionally, so there need not be anymore a separate call to
xen_modified_memory.

Paolo Bonzini 72b47e79ce exec: invert return value of cpu_physical_memory_get_clean, rename
While it is obvious that cpu_physical_memory_get_dirty returns true even if
a single page is dirty, the same is not true for cpu_physical_memory_get_clean;
one would expect that it returns true only if all the pages are clean, but
it actually looks for even one clean page.  (By contrast, the caller of that
function, cpu_physical_memory_range_includes_clean, has a good name).

To clarify, rename the function to cpu_physical_memory_all_dirty and return
true if _all_ the pages are dirty.  This is the opposite of the previous
meaning, because "all are 1" is the same as "not (any is 0)", so we have to
modify cpu_physical_memory_range_includes_clean as well.

Paolo Bonzini b2dfd71c48 memory: prepare for multiple bits in the dirty log mask
When the dirty log mask will also cover other bits than DIRTY_MEMORY_VGA,
some listeners may be interested in the overall zero/non-zero value of
the dirty log mask; others may be interested in the value of single bits.

For this reason, always call log_start/log_stop if bits have respectively
appeared or disappeared, and pass the old and new values of the dirty log
mask so that listeners can distinguish the kinds of change.

For example, KVM checks if dirty logging used to be completely disabled
(in log_start) or is now completely disabled (in log_stop).  On the
other hand, Xen has to check manually if DIRTY_MEMORY_VGA changed,
since that is the only bit it cares about.

While VGA-specific users (including the Xen listener!) will want to keep

Jason Wang 309750fad5 vhost: logs sharing
Currently we allocate one vhost log per vhost device. This is sub
optimal when:

- Guest has several device with vhost as backend
- Guest has multiqueue devices

In the above cases, we can avoid the memory allocation by sharing a
single vhost log among all the vhost devices. This is done through:

- Introducing a new vhost_log structure with refcnt inside.
- Using a global pointer to vhost_log structure that will be used. And
  introduce helper to get the log with expected log size and helper to
- drop the refcnt to the old log.
- Each vhost device still keep track of a pointer to the log that was
  used.

With above, if no resize happens, all vhost device will share a single
vhost log. During resize, a new vhost_log structure will be allocated
and made for the global pointer. And each vhost devices will drop the
refcnt to the old log.

Tested by doing scp during migration for a 2 queues virtio-net-pci.

Laszlo Ersek 6e7d82497d hw/acpi: piix4_pm_init(): take fw_cfg object no more
This PIIX4 init function has no more reason to receive a pointer to the
FwCfg object. Remove the parameter from the prototype, and update callers.

As a result, the pc_init1() function no longer needs to save the return
value of pc_memory_init() and xen_load_linux(), which makes it more
similar to pc_q35_init().

The return type & value of pc_memory_init() and xen_load_linux() are not
changed themselves; maybe we'll need their return values sometime later.

Michael Roth e4b798bb53 spapr_drc: add spapr_drc_populate_dt()
This function handles generation of ibm,drc-* array device tree
properties to describe DRC topology to guests. This will by used
by the guest to direct RTAS calls to manage any dynamic resources
we associate with a particular DR Connector as part of
hotplug/unplug.

Since general management of boot-time device trees are handled
outside of sPAPRDRConnector, we insert these values blindly given
an FDT and offset. A mask of sPAPRDRConnector types is given to
instruct us on what types of connectors entries should be generated
for, since descriptions for different connectors may live in
different parts of the device tree.

Based on code originally written by Nathan Fontenot.

Tyrel Datwyler 79853e18d9 spapr_events: event-scan RTAS interface
We don't actually rely on this interface to surface hotplug events, and
instead rely on the similar-but-interrupt-driven check-exception RTAS
interface used for EPOW events. However, the existence of this interface
is needed to ensure guest kernels initialize the event-reporting
interfaces which will in turn be used by userspace tools to handle these
events, so we implement this interface here.

Since events surfaced by this call are mutually exclusive to those
surfaced via check-exception, we also update the RTAS event queue code
to accept a boolean to mark/filter for events accordingly.

Events of this sort are not currently generated by QEMU, but the interface
has been tested by surfacing hotplug events via event-scan in place
of check-exception.

Nathan Fontenot 31fe14d15d spapr_events: re-use EPOW event infrastructure for hotplug events
This extends the data structures currently used to report EPOW events to
guests via the check-exception RTAS interfaces to also include event types
for hotplug/unplug events.

This is currently undocumented and being finalized for inclusion in PAPR
specification, but we implement this here as an extension for guest
userspace tools to implement (existing guest kernels simply log these
events via a sysfs interface that's read by rtas_errd, and current
versions of rtas_errd/powerpc-utils already support the use of this
mechanism for initiating hotplug operations).

We also add support for queues of pending RTAS events, since in the
case of hotplug there's chance for multiple events being in-flight
at any point in time.

Michael Roth 46503c2bc0 spapr_rtas: add ibm, configure-connector RTAS interface
This interface is used to fetch an OF device-tree nodes that describes a
newly-attached device to guest. It is called multiple times to walk the
device-tree node and fetch individual properties into a 'workarea'/buffer
provided by the guest.

The device-tree is generated by QEMU and passed to an sPAPRDRConnector during
the initial hotplug operation, and the state of these RTAS calls is tracked by
the sPAPRDRConnector. When the last of these properties is successfully
fetched, we report as special return value to the guest and transition
the device to a 'configured' state on the QEMU/DRC side.

this interface.

Michael Roth bbf5c878ab spapr_drc: initial implementation of sPAPRDRConnector device
This device emulates a firmware abstraction used by pSeries guests to
manage hotplug/dynamic-reconfiguration of host-bridges, PCI devices,
memory, and CPUs. It is conceptually similar to an SHPC device,
complete with LED indicators to identify individual slots to physical
physical users and indicate when it is safe to remove a device. In
some cases it is also used to manage virtualized resources, such a
memory, CPUs, and physical-host bridges, which in the case of pSeries
guests are virtualized resources where the physical components are
managed by the host.

Guests communicate with these DR Connectors using RTAS calls,
generally by addressing the unique DRC index associated with a
particular connector for a particular resource. For introspection
purposes we expose this state initially as QOM properties, and
in subsequent patches will introduce the RTAS calls that make use of
it. This constitutes to the 'guest' interface.

On the QEMU side we provide an attach/detach interface to associate
or cleanup a DeviceState with a particular sPAPRDRConnector in
response to hotplug/unplug, respectively. This constitutes the
'physical' interface to the DR Connector.

Marcel Apfelbaum 40d14bef80 hw/pci: introduce PCI Expander Bridge (PXB)
PXB is a "light-weight" host bridge whose purpose is to enable
the main host bridge to support multiple PCI root buses
for pc machines.

As oposed to PCI-2-PCI bridge's secondary bus, PXB's bus
is a primary bus and can be associated with a NUMA node
(different from the main host bridge) allowing the guest OS
to recognize the proximity of a pass-through device to
other resources as RAM and CPUs.

The PXB is composed from:
 - A primary PCI bus (can be associated with a NUMA node)
   Acts like a normal pci bus and from the functionality point
   of view is an "expansion" of the bus behind the
   main host bridge.
 - A pci-2-pci bridge behind the primary PCI bus where the actual
   devices will be attached.
 - A host-bridge PCI device
   Situated on the bus behind the main host bridge, allows
   the BIOS to configure the bus number and IO/mem resources.
   It does not have its own config/data register for configuration
   cycles, this being handled by the main host bridge.
-  A host-bridge sysbus to comply with QEMU current design.

Eric Auger 5f7a5a0edc hw/arm/virt: add dynamic sysbus device support
Allows sysbus devices to be instantiated from command line by
using -device option. Machvirt creates a platform bus at init.
The dynamic sysbus devices are attached to this platform bus device.

The platform bus device registers a machine init done notifier
whose role will be to bind the dynamic sysbus devices. Indeed
dynamic sysbus devices are created after machine init.

machvirt also registers a notifier that will build the device
tree nodes for the platform bus and its children dynamic sysbus
devices.

Eric Auger ac9d32e396 hw/arm/boot: arm_load_kernel implemented as a machine init done notifier
Device tree nodes for the platform bus and its children dynamic sysbus
devices are added in a machine init done notifier. To load the dtb once,
after those latter nodes are built and before ROM freeze, the actual
arm_load_kernel existing code is moved into a notifier notify function,
arm_load_kernel_notify. arm_load_kernel now only registers the
corresponding notifier.

Machine files that do not support platform bus stay unchanged. Machine
files willing to support dynamic sysbus devices must call arm_load_kernel
before sysbus-fdt arm_register_platform_bus_fdt_creator to make sure
dynamic sysbus device nodes are integrated in the dtb.

Markus Armbruster 04e00c92ef monitor: Use trad. command interface for HMP pcie_aer_inject_error
All QMP commands use the "new" handler interface (mhandler.cmd_new).
Most HMP commands still use the traditional interface (mhandler.cmd),
but a few use the "new" one.  Complicates handle_user_command() for no
gain, so I'm converting these to the traditional interface.

pcie_aer_inject_error's implementation is split into the
hmp_pcie_aer_inject_error() and pcie_aer_inject_error_print().  The
former is a peculiar crossbreed between HMP and QMP handler.  On
success, it works like a QMP handler: store QDict through ret_data
parameter, return 0.  Printing the QDict is left to
pcie_aer_inject_error_print().  On failure, it works more like an HMP
handler: print error to monitor, return negative number.

To convert to the traditional interface, turn
pcie_aer_inject_error_print() into a command handler wrapping around
hmp_pcie_aer_inject_error().  By convention, this command handler
should be called hmp_pcie_aer_inject_error(), so rename the existing
hmp_pcie_aer_inject_error() to do_pcie_aer_inject_error().

Markus Armbruster 65207c59d9 monitor: Drop broken, unused asynchronous command interface
The asynchronous monitor command interface goes back to commit 940cc30
(Jan 2010).  Added a third case to command execution.  The hope back
then according to the commit message was that all commands get
converted to the asynchronous interface, killing off the other two
cases.  Didn't happen.

The initial asynchronous commands balloon and info balloon were
converted back to synchronous long ago (commit 96637bc and d72f32),
with commit messages calling the asynchronous interface "not fully
working" and "deprecated".  The only other user went away in commit
3b5704b.

New code generally uses synchronous commands and asynchronous events.

What exactly is still "not fully working" with asynchronous commands?
Well, here's a bug that defeats actual asynchronous use pretty
reliably: the reply's ID is wrong (and has always been wrong) unless
you use the command synchronously!  To reproduce, we need an
asynchronous command, so we have to go back before commit 3b5704b.
Run QEMU with spice:

    $ qemu-system-x86_64 -nodefaults -S -spice port=5900,disable-ticketing -qmp stdio
    {"QMP": {"version": {"qemu": {"micro": 94, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}}

Connect a spice client in another terminal:

    $ remote-viewer spice://localhost:5900

Set up a migration destination dummy in a third terminal:

    $ socat TCP-LISTEN:12345 STDIO

Now paste the following into the QMP monitor:

    { "execute": "qmp_capabilities", "id": "i0" }
    { "execute": "client_migrate_info", "id": "i1", "arguments": { "protocol": "spice", "hostname": "localhost", "port": 12345 } }
    { "execute": "query-kvm", "id": "i2" }

Produces two replies immediately, one to qmp_capabilities, and one to
query-kvm:

    {"return": {}, "id": "i0"}
    {"return": {"enabled": false, "present": true}, "id": "i2"}

Both are correct.  Two lines of debug output from libspice-server not
shown.

Now EOF socat's standard input to make it close the connection.  This
makes the asynchronous client_migrate_info complete.  It replies:

    {"return": {}}

Bug: "id": "i1" is missing.  Two lines of debug output from
libspice-server not shown.  Cherry on top: storage for the missing ID
is leaked.

Get rid of this stuff before somebody hurts himself with it.

Stefan Berger 5cb18b3d7b TPM2 ACPI table support
Add a TPM2 ACPI table if a TPM 2 is used in the backend.
Also add an SSDT for the TPM 2.

Rename tpm_find() to tpm_get_version() and have this function
return the version of the TPM found, TPMVersion_Unspec if
no TPM is found. Use the version number to build version
specific ACPI tables.

Stefan Berger 116694c34a Extend TPM TIS interface to support TPM 2
Following the recent upgrade to version 1.3, extend the TPM TIS
interface with capabilities introduced for support of a TPM 2.

TPM TIS for TPM 2 introduced the following extensions beyond the
TPM TIS 1.3 (used for TPM 1.2):

- A new 32bit interface Id register was introduced.
- New flags for the status (STS) register were defined.
- New flags for the capability flags were defined.

Support the above if a TPM TIS 1.3 for TPM 2 is used with a TPM 2
on the backend side. Support the old TPM TIS 1.3 configuration if a
TPM 1.2 is being used. A subsequent patch will then determine which
TPM version is being used in the backend.

Laszlo Ersek fd53c87cf6 i386/pc: pc_basic_device_init(): delegate FDC creation request
This patch introduces no observable change, but it allows the callers of
pc_basic_device_init(), ie. pc_init1() and pc_q35_init(), to request (or
not request) the creation of the FDC explicitly.

At the moment both callers pass constant create_fdctrl=true (hence no
observable change).

Assuming a board passes create_fdctrl=false, "floppy" will be NULL on
output, and (beyond the FDC not being created) that NULL will be passed on
to pc_cmos_init(). Luckily, pc_cmos_init() already handles that case.

John Snow 9abe3bdc45 qapi: add dirty bitmap status
Bitmaps can be in a handful of different states with potentially
more to come as we tool around with migration and persistence patches.

Management applications may need to know why certain bitmaps are
unavailable for various commands, e.g. busy in another operation,
busy being migrated, etc.

Right now, all we offer is BlockDirtyInfo's boolean member 'frozen'.
Instead of adding more booleans, replace it by an enumeration member
'status' with values 'active' and 'frozen'.  Then add new value
'disabled'.

Incompatible change.  Fine because the changed part hasn't been
released so far.

Note that gtk got native opengl support with release 3.16.
There most likely will be a separate implementation for 3.16+,

Denis V. Lunev 4196d2f030 block: minimal bounce buffer alignment
The patch introduces new concept: minimal memory alignment for bounce
buffers. Original so called "optimal" value is actually minimal required
value for aligment. It should be used for validation that the IOVec
is properly aligned and bounce buffer is not required.

Though, from the performance point of view, it would be better if
bounce buffer or IOVec allocated by QEMU will be aligned stricter.

The patch does not change any alignment value yet.

Fabian Aggeler 3295186083 hw/intc/arm_gic: Make ICCICR/GICC_CTLR banked
ICCICR/GICC_CTLR is banked in GICv1 implementations with Security
Extensions or in GICv2 in independent from Security Extensions.
This makes it possible to enable forwarding of interrupts from
the CPU interfaces to the connected processors for Group0 and Group1.

We also allow to set additional bits like AckCtl and FIQEn by changing
the type from bool to uint32. Since the field does not only store the
enable bit anymore and since we are touching the vmstate, we use the
opportunity to rename the field to cpu_ctlr.

ICDDCR/GICD_CTLR is banked if the GIC has the security extensions,

Group1 enable if the GIC implements interrupt groups.

EnableGroup0 (Bit [1]) in GICv1 is architecturally IMPDEF. Since this
bit (Enable Non-secure) is present in the integrated GIC of the Cortex-A9
MPCore, we support this bit in our GICv1 implementation too.

Fabian Aggeler c27a5ba948 hw/intc/arm_gic: Add Interrupt Group Registers
The Interrupt Group Registers allow the guest to configure interrupts
into one of two groups, where Group0 are higher priority and may
be routed to IRQ or FIQ, and Group1 are lower priority and always
routed to IRQ. (In a GIC with the security extensions Group0 is
Secure interrupts and Group 1 is NonSecure.)
The GICv2 always supports interrupt grouping; the GICv1 does only
if it implements the security extensions.

This patch implements the ability to read and write the registers;
the actual functionality the bits control will be added in a
subsequent patch.

Markus Armbruster 481b002cc8 qobject: Add a special null QObject
I'm going to fix the JSON parser to recognize null.  The obvious
representation of JSON null as (QObject *)NULL doesn't work, because
the parser already uses it as an error value.  Perhaps we should
change it to free NULL for null, but that's more than I can do right
now.  Create a special null QObject instead.

The existing QDict, QList, and QString all represent something that
is a pointer in C and could therefore be associated with NULL.  But
right now, all three of these sub-types are always non-null once
created, so the new null sentinel object is intentionally unrelated
to them.

Michael Tokarev f20f2a1f33 glib-compat.h: change assert to g_assert
include/glib-compat.h defines a bunch of functions based on glib primitives,
and uses assert() without including assert.h.  Replace assert() with
g_assert() to make the file more self-contained, and to fix compilation
breakage after 28507a415a.

Shannon Zhao da2f84d127 virtio-scsi: Move DEFINE_VIRTIO_SCSI_FEATURES to virtio-scsi
So far virtio-scsi-device can't expose host features to guest while
using virtio-mmio because it doesn't set DEFINE_VIRTIO_SCSI_FEATURES on
backend or transport.

The host features belong to the backends while virtio-scsi-pci,
virtio-scsi-s390 and virtio-scsi-ccw set the DEFINE_VIRTIO_SCSI_FEATURES
on transports. But they already have the ability to forward property
accesses to the backend child. So if we move the host features to
backends, it doesn't break the backwards compatibility for them and
make host features work while using virtio-mmio.

Move DEFINE_VIRTIO_SCSI_FEATURES to the backend virtio-scsi. The
transports just sync the host features from backends.

So far virtio-net-device can't expose host features to guest while
using virtio-mmio because it doesn't set DEFINE_VIRTIO_NET_FEATURES on
backend or transport. So the performance is low.

The host features belong to the backend while virtio-net-pci,

Here we move DEFINE_VIRTIO_NET_FEATURES to the backend virtio-net. The

virtio_net_set_config_size to virtio-net to make sure the config size
is correct and don't expose it.

Add bdrv_clear_dirty_bitmap and a matching QMP command,
qmp_block_dirty_bitmap_clear that enables a user to reset
the bitmap attached to a drive.

This allows us to reset a bitmap in the event of a full

John Snow 9bd2b08f27 block: Add bitmap successors
A bitmap successor is an anonymous BdrvDirtyBitmap that is intended to
be created just prior to a sensitive operation (e.g. Incremental Backup)
that can either succeed or fail, but during the course of which we still
want a bitmap tracking writes.

On creating a successor, we "freeze" the parent bitmap which prevents
its deletion, enabling, anonymization, or creating a bitmap with the
same name.

On success, the parent bitmap can "abdicate" responsibility to the
successor, which will inherit its name. The successor will have been
tracking writes during the course of the backup operation. The parent
will be safely deleted.

On failure, we can "reclaim" the successor from the parent, unifying
them such that the resulting bitmap describes all writes occurring since
the last successful backup, for instance. Reclamation will thaw the
parent, but not explicitly re-enable it.

BdrvDirtyBitmap operations that target a single bitmap are protected
by assertions that the bitmap is not frozen and/or disabled.

BdrvDirtyBitmap operations that target a group of bitmaps, such as
bdrv_{set,reset}_dirty will ignore frozen/disabled drives with a
conditional instead.

Internal functions that enable/disable dirty bitmaps have assertions
added to them to prevent modifying frozen bitmaps.

John Snow b8e6fb752e block: Add bitmap disabled status
Add a status indicating the enabled/disabled state of the bitmap.
A bitmap is by default enabled, but you can lock the bitmap into
a read-only state by setting disabled = true.

A previous version of this patch added a QMP interface for changing
the state of the bitmap, but it has since been removed for now until
a use case emerges where this state must be revealed to the user.

The disabled state WILL be used internally for bitmap migration and
bitmap persistence.

John Snow be58721dbf hbitmap: add hbitmap_merge
We add a bitmap merge operation to assist in error cases
where we wish to combine two bitmaps together.

This is algorithmically O(bits) provided HBITMAP_LEVELS remains
constant. For a full bitmap on a 64bit machine:
sum(bits/64^k, k, 0, HBITMAP_LEVELS) ~= 1.01587 * bits

We may be able to improve running speed for particularly sparse
bitmaps by using iterators, but the running time for dense maps
will be worse.

We present the simpler solution first, and we can refine it later
if needed.

John Snow 341ebc2f81 qmp: Add block-dirty-bitmap-add and block-dirty-bitmap-remove
The new command pair is added to manage a user created dirty bitmap. The
dirty bitmap's name is mandatory and must be unique for the same device,
but different devices can have bitmaps with the same names.

The granularity is an optional field. If it is not specified, we will
choose a default granularity based on the cluster size if available,
clamped to between 4K and 64K to mirror how the 'mirror' code was
already choosing granularity. If we do not have cluster size info
available, we choose 64K. This code has been factored out into a helper
shared with block/mirror.

This patch also introduces the 'block_dirty_bitmap_lookup' helper,
which takes a device name and a dirty bitmap name and validates the
lookup, returning NULL and setting errp if there is a problem with
either field. This helper will be re-used in future patches in this
series.

The types added to block-core.json will be re-used in future patches
in this series, see:
'qapi: Add transaction support to block-dirty-bitmap-{add, enable, disable}'

object. However that is being filled in by bdrv_query_info(), not by
bdrv_block_device_info(), which is where BlockDeviceInfo is actually

Anyone calling bdrv_block_device_info() directly will get a null image

crashes QEMU.

bdrv_query_info() to bdrv_block_device_info().

Fam Zheng 751ebd76e6 blockjob: Allow nested pause
This patch changes block_job_pause to increase the pause counter and
block_job_resume to decrease it.

The counter will allow calling block_job_pause/block_job_resume
unconditionally on a job when we need to suspend the IO temporarily.

From now on, each block_job_resume must be paired with a block_job_pause
to keep the counter balanced.

The user pause from QMP or HMP will only trigger block_job_pause once
until it's resumed, this is achieved by adding a user_paused flag in
BlockJob.

One occurrence of block_job_resume in mirror_complete is replaced with
block_job_enter which does what is necessary.

In block_job_cancel, the cancel flag is good enough to instruct
coroutines to quit loop, so use block_job_enter to replace the unpaired
block_job_resume.

Upon block job IO error, user is notified about the entering to the
pause state, so this pause belongs to user pause, set the flag
accordingly and expect a matching QMP resume.

QLISTs was queried through a transport specific method. When guest
setting vectors, the virtqueue will be linked and helpers for traverse
the list was also introduced.

The first user will be virtio pci which will use this to speed up

Markus Armbruster 3b5704b2f8 monitor: Make client_migrate_info synchronous
Live migration with spice works like this today:

  (1) client_migrate_info monitor cmd
  (2) spice server notifies client, client connects to target host.
  (3) qemu waits until spice client connect is finished.
  (4) send over vmstate (i.e. main part of live migration).
  (5) spice handover to target host.

(3) is implemented by making client_migrate_info a async monitor
command.  This is the only async monitor command we have.

The original reason to implement this dance was that qemu did not accept
new tcp connections while the incoming migration was running, so (2) and
(4) could not be done in parallel.  That issue was fixed long ago though.
Qemu version 1.3.0 (released Dec 2012) and newer happily accept tcp
connects while the incoming migration runs.

Time to drop step (3).  This patch does exactly that, by making the
monitor command synchronous and removing the code needed to handle the
async monitor command in ui/spice-core.c

Peter Maydell cc05c43ad9 memory: Define API for MemoryRegionOps to take attrs and return status
Define an API so that devices can register MemoryRegionOps whose read
and write callback functions are passed an arbitrary pointer to some
transaction attributes and can return a success-or-failure status code.
This will allow us to model devices which:
 * behave differently for ARM Secure/NonSecure memory accesses
 * behave differently for privileged/unprivileged accesses
 * may return a transaction failure (causing a guest exception)
   for erroneous accesses

This patch defines the new API and plumbs the attributes parameter through
to the memory.c public level functions io_mem_read() and io_mem_write(),
where it is currently dummied out.

The success/failure response indication is also propagated out to
io_mem_read() and io_mem_write(), which retain the old-style
boolean true-for-error return.

Paolo Bonzini a59629fcc6 rcu: do not create thread in pthread_atfork callback
If QEMU forks after the CPU threads have been created, qemu_mutex_lock_iothread
will not be able to do qemu_cpu_kick_thread.  There is no solution other than
assuming that forks after the CPU threads have been created will end up in an
exec.  Forks before the CPU threads have been created (such as -daemonize)
have to call rcu_after_fork manually.

Notably, the oxygen theme for GTK+ forks and shows a "No such process" error
without this patch.

This patch can be reverted once the iothread loses the "kick the TCG thread"
magic.

User-mode emulation does not use the iothread, so it can also call
rcu_after_fork.

Amit Shah 4add73aa60 virtio: serial: expose a 'guest_writable' callback for users
Users of virtio-serial may want to know when a port becomes writable.  A
port can stop accepting writes if the guest port is open but not being
read from.  In this case, data gets queued up in the virtqueue, and
after the vq is full, writes to the port do not succeed.

When the guest reads off a vq element, and adds a new one for the host
to put data in, we can tell users the port is available for more writes,
via the new ->guest_writable() callback.

Alexey Kardashevskiy 89d5cbddee profiler: Reenable built-in profiler
2ed1ebcf6 "timer: replace time() with QEMU_CLOCK_HOST" broke compile
when configured with --enable-profiler. Turned out the profiler has been
broken for a while.

This does s/qemu_time/tcg_time/ as the profiler only works in a TCG mode.
This also fixes the compile error.

This changes profile_getclock() to return nanoseconds rather than
CPU ticks as the "profile" HMP command prints seconds and there is no
platform-independent way to get ticks-per-second rate.
Since TCG is quite slow and get_clock() returns nanoseconds (fine
enough), this should not affect precision much.

This removes unused qemu_time_start and tlb_flush_time.

Dominik Dingel d0a073a186 kvm: encapsulate HAS_DEVICE for vm attrs
More and more virtual machine specifics between kvm and qemu will be
transferred with vm attributes.
So we encapsulate the common logic in a generic function.

Additionally we need only to check during initialization if kvm supports
virtual machine attributes.

Richard Henderson 42a268c241 tcg: Change translator-side labels to a pointer
This is improved type checking for the translators -- it's no longer
possible to accidentally swap arguments to the branch functions.

Note that the code generating backends still manipulate labels as int.

With notable exceptions, the scope of the change is just a few lines
for each target, so it's not worth building extra machinery to do this
change in per-target increments.

Paolo Bonzini 2120465fbb queue: fix QSLIST_INSERT_HEAD_ATOMIC race
There is a not-so-subtle race in QSLIST_INSERT_HEAD_ATOMIC.

Because atomic_cmpxchg returns the old value instead of a success flag,
QSLIST_INSERT_HEAD_ATOMIC was checking for success by comparing against
the second argument to atomic_cmpxchg.  Unfortunately, this only works
if the second argument is a local or thread-local variable.

If it is in memory, it can be subject to common subexpression elimination
(and then everything's fine) or reloaded after the atomic_cmpxchg,
depending on the compiler's whims.  If the latter happens, the race can
happen.  A thread can sneak in, doing something on elm->field.sle_next
after the atomic_cmpxchg and before the comparison.  This causes a wrong
failure, and then two threads are using "elm" at the same time.  In the
case discovered by Christian, the sequence was likely something like this:

    thread 1                   | thread 2
    QSLIST_INSERT_HEAD_ATOMIC  |
      atomic_cmpxchg succeeds  |
      elm added to list        |
                               | steal release_pool
                               | QSLIST_REMOVE_HEAD
                               | elm removed from list
                               | ...
                               | QSLIST_INSERT_HEAD_ATOMIC
                               |   (overwrites sle_next)
      spurious failure         |
      atomic_cmpxchg succeeds  |
      elm added to list again  |
                               |
    steal release_pool         |
    QSLIST_REMOVE_HEAD         |
    elm removed again          |

The last three steps could be done by a third thread as well.
A reproducer that failed in a matter of seconds is as follows:

- the guest has 32 VCPUs on a 28 core host (hyperthreading was enabled),
  memory was 16G just to err on the safe side (the host has 64G, but hey
  at least you need no s390)

- the guest has 24 null-aio virtio-blk devices using dataplane
  (-object iothread,id=ioN -drive if=none,id=blkN,driver=null-aio,size=500G
  -device virtio-blk-pci,iothread=ioN,drive=blkN)

- the guest also has a single network interface.  It's only doing loopback
  tests so slirp vs. tap and the model doesn't matter.

- the guest is running fio with the following script:

     [global]
     rw=randread
     blocksize=16k
     ioengine=libaio
     runtime=10m

Moral of the story: I should refrain from writing more clever stuff.
At least it looks like it is not too clever to be undebuggable.

Peter Maydell 4f9950520a bitops.h: sextract64() return type should be int64_t, not uint64_t
The documentation for sextract64() claims that the return type is
an int64_t, but the code itself disagrees. Fix the return type to
conform to the documentation and to bring it into line with
sextract32(), which returns int32_t.

Ekaterina Tumanova 0eb28a4228 BlockConf: Call backend functions to detect geometry and blocksizes
geometry: hd_geometry_guess function autodetects the drive geometry.
This patch adds a block backend call, that probes the backing device
geometry. If the inner driver method is implemented and succeeds
(currently only for DASDs), the blkconf_geometry will pass-through
the backing device geometry. Otherwise will fallback to old logic.

blocksize: This patch initializes blocksize properties to 0.
In order to set the property a blkconf_blocksizes was introduced.
If user didn't set physical or logical blocksize, it will
retrieve its value from a driver (only succeeds for DASD), otherwise
it will set default 512 value.

The blkconf_blocksizes call was added to all users of BlkConf.

Markus Armbruster 9b3d111ad9 hw: Propagate errors through qdev_prop_set_drive()
Three kinds of callers:

1. On failure, report the error and abort

   Passing &error_abort does the job.  No functional change.

2. On failure, report the error and exit()

   This is qdev_prop_set_drive_nofail().  Error reporting moves from
   qdev_prop_set_drive() to its caller.  Because hiding away the error
   in the monitor right before exit() isn't helpful, replace
   qerror_report_err() by error_report_err().  Shouldn't make a
   difference, because qdev_prop_set_drive_nofail() should never be
   used in QMP context.

3. On failure, report the error and recover

   This is usb_msd_init() and scsi_bus_legacy_add_drive().  Error
   reporting and freeing the error object moves from
   qdev_prop_set_drive() to its callers.

   Because usb_msd_init() can't run in QMP context, replace
   qerror_report_err() by error_report_err() there.

   No functional change.

   scsi_bus_legacy_add_drive() calling qerror_report_err() is of
   course inappropriate, but this commit merely makes it more obvious.
   The next one will clean it up.

Gavin Shan ee954280da sPAPR: Implement EEH RTAS calls
The emulation for EEH RTAS requests from guest isn't covered
by QEMU yet and the patch implements them.

The patch defines constants used by EEH RTAS calls and adds
callbacks sPAPRPHBClass::{eeh_set_option, eeh_get_state, eeh_reset,
eeh_configure}, which are going to be used as follows:

  * RTAS calls are received in spapr_pci.c, sanity check is done
    there.
  * RTAS handlers handle what they can. If there is something it
    cannot handle and the corresponding sPAPRPHBClass callback is
    defined, it is called.
  * Those callbacks are only implemented for VFIO now. They do ioctl()
    to the IOMMU container fd to complete the calls. Error codes from
    that ioctl() are transferred back to the guest.

David Gibson 880ae7de59 pseries: Move rtc_offset into RTC device's state structure
The initial creation of the PAPR RTC qdev class left a wart - the rtc's
offset was left in the sPAPREnvironment structure, accessed via a global.

This patch moves it into the RTC device's own state structure, were it
belongs.  This requires a small change to the migration stream format.  In
order to handle incoming streams from older versions, we also need to
retain the rtc_offset field in the sPAPREnvironment structure, so that it
can be loaded into via the vmsd, then pushed into the RTC device.

Since we're changing the migration format, this also takes the opportunity
to:

  * Change the rtc offset from a value in seconds to a value in
    nanoseconds, allowing nanosecond offsets between host and guest
    rtc time, if desired.

  * Remove both the already unused "next_irq" field and now unused
    "rtc_offset" field from the new version of the spapr migration
    stream

David Gibson 28df36a13a pseries: Make the PAPR RTC a qdev device
At present the PAPR RTC isn't a "device" as such - it's accessed only via
firmware/hypervisor calls, and is handled in the sPAPR core code.  This
becomes inconvenient as we extend it in various ways.

This patch makes the PAPR RTC a separate device in the qemu device model.

For now, the only piece of device state - the rtc_offset - is still kept in
the global sPAPREnvironment structure.  That's clearly wrong, but leaving
it to be fixed in a following patch makes for a clearer separation between
the internal re-organization of the device, and the behavioural changes
(because the migration stream format needs to change slightly when the
offset is moved into the device's own state).

is in the RTAS get-time-of-day function which returns the RTC time to the
guest.  Second is in the spapr events code which is used to timestamp
event messages from the hypervisor to the guest.

Currently both call qemu_get_timedate() directly, but we want to change
that so we can properly handle the various -rtc options.  In preparation,
create a helper function to return the virtual RTC time.

Alexey Kardashevskiy b194df478a spapr-pci: Enable huge BARs
At the moment sPAPR only supports 512MB window for MMIO BARs. However
modern devices might want bigger 64bit BARs.

This extends MMIO window from 512MB to 62GB (aligned to
SPAPR_PCI_WINDOW_SPACING) and advertises it in 2 records in
the PHB "ranges" property. 32bit gets the space from
SPAPR_PCI_MEM_WIN_BUS_OFFSET till the end of 4GB, 64bit gets the rest
of the space. If no space is left, 64bit range is not advertised.

The MMIO space size is set to old value of 0x20000000 by default
for pseries machines older than 2.3.

The approach changes the device tree which is a guest visible change, however
it won't break migration as:
1. we do not support migration to older QEMU versions
2. migration to newer QEMU will migrate the device tree as well and since
the new layout only extends the old one and does not change address mappigns,
no breakage is expected here too.

SLOF change is required to utilize this extension.

David Gibson 3e4ac96871 pseries: Limit PCI host bridge "index" value
pseries guests can have large numbers of PCI host bridges.  To avoid the
user having to specify a number of different configuration values for every
one, the device supports an "index" property which is a shorthand setting
the various window and configuration addresses from a predefined sensible
set.

There are some problems with the details at present:
  * The "index" propery is signed, but negative values will create PCI
windows below where we expect, potentially colliding with other devices
  * No limit is imposed on the "index" property and large values can
translate to extremely large window addresses.  With PCI passthrough in
particular this can mean we exceed various mapping and physical address
limits causing the guest host bridge to not work in strange ways.

This patch addresses this, by making "index" unsigned, and imposing a
limit.  Currently the limit allows indices from 0..255 which is probably
enough host bridges for the time being.  It's fairly easy to extend if
we discover we need more.

Alexey Kardashevskiy ee9a569ab8 spapr_vio/spapr_iommu: Move VIO bypass where it belongs
Instead of tweaking a TCE table device by adding there a bypass flag,
let's add an alias to RAM and IOMMU memory region, and enable/disable
those according to the selected bypass mode.
This way IOMMU memory region can have size of the actual window rather
than ram_size which is essential for upcoming DDW support.

This moves bypass logic to VIO layer and keeps @bypass flag in TCE table
for migration compatibility only. This replaces spapr_tce_set_bypass()
calls with explicit assignment to avoid confusion as the function could
do something more that just syncing the @bypass flag.

This adds a pointer to VIO device into the sPAPRTCETable struct to provide
the sPAPRTCETable device a way to update bypass mode for the VIO device.

But when you create the VDI which doesn't have default object size
with qemu-img command, you specify object_size option.

If you want to create a VDI of 8MB object size,
you need to specify following command option.

 # qemu-img create -o object_size=8M sheepdog:test1 100M

In addition, when you don't specify qemu-img command option,
a default value of sheepdog cluster is used for creating VDI.

zhanghailiang 87a45cfee6 pc-dimm: add a function to calculate VM's current RAM size
The global parameter 'ram_size' does not take into account
the hotplugged memory.

In some codes, we use 'ram_size' as current VM's real RAM size,
which is not correct.

Add function 'get_current_ram_size' to calculate VM's current RAM size,
it will enumerate present memory devices and also plus ram_size.

Samuel Pitoiset 6ee47c9008 vfio: allow to disable MMAP per device with -x-mmap=off option
Disabling MMAP support uses the slower read/write accesses but allows to
trace all MMIO accesses, which is not good for performance, but very
useful for reverse engineering PCI drivers. This option allows to
disable MMAP per device without a compile-time change.

Markus Armbruster f51074cdc6 pci-hotplug-old: Has been dead for five major releases, bury
Commit 79ca616 (v1.6.0) accidentally disabled legacy x86-only HMP
commands pci_add, pci_del: it defined CONFIG_PCI_HOTPLUG only as make
variable, not as preprocessor macro, killing the code conditional on
defined(CONFIG_PCI_HOTPLUG_OLD).

In all this time, nobody reported the loss.  I only noticed it when I
tried to test some error reporting change that forced me to touch this
old crap again.

Fun: git-log hw/pci/pci-hotplug-old.c shows our faith in the backward
compatibility god has been strong enough to sacrifice at its altar
about a dozen times, but not strong enough to even once verify the
legacy feature's still there, let alone works.

Remove the commands along with the code backing them.

Fam Zheng 2e5b887cfc block: Forbid bdrv_set_aio_context outside BQL
Even if the caller has both the old and the new AioContext's, there can
be a deadlock, due to the leading bdrv_drain_all.

Suppose there are four io threads (A, B, A0, B0) with A and B owning a
BDS for each (bs_a, bs_b); Now A wants to move bs_a to iothread A0, and
B wants to move bs_b to B0, at the same time:

  iothread A                           iothread B
--------------------------------------------------------------------------
  aio_context_acquire(A0) /* OK */     aio_context_acquire(B0) /* OK */
  bdrv_set_aio_context(bs_a, A0)       bdrv_set_aio_context(bs_b, B0)
  -> bdrv_drain_all()                  -> bdrv_drain_all()
     -> acquire A /* OK */               -> acquire A /* blocked */
     -> acquire B /* blocked */          -> acquire B
     ...                                 ...

Deadlock happens because A is waiting for B, and B is waiting for A.

Markus Armbruster dc523cd348 qemu-img: Suppress unhelpful extra errors in convert, amend
img_convert() and img_amend() use qemu_opts_do_parse(), which reports
errors with qerror_report_err().  Its error messages aren't helpful
here, the caller reports one that actually makes sense.  Reproducer:

    $ qemu-img convert -o backing_format=raw in.img out.img
    qemu-img: Invalid parameter 'backing_format'
    qemu-img: Invalid options for file format 'raw'

To fix, propagate errors through qemu_opts_do_parse().  This lifts the
error reporting into callers.  Drop it from img_convert() and
img_amend(), keep it in qemu_chr_parse_compat(), bdrv_img_create().

Since I'm touching qemu_opts_do_parse() anyway, write a function
comment for it.

Markus Armbruster f43e47dbf6 QemuOpts: Drop qemu_opt_set(), rename qemu_opt_set_err(), fix use
qemu_opt_set() is a wrapper around qemu_opt_set() that reports the
error with qerror_report_err().

Most of its users assume the function can't fail.  Make them use
qemu_opt_set_err() with &error_abort, so that should the assumption
ever break, it'll break noisily.

Just two users remain, in util/qemu-config.c.  Switch them to
qemu_opt_set_err() as well, then rename qemu_opt_set_err() to
qemu_opt_set().

Igor Mammedov ddf1ec2ffe pc: acpi-build: create CPU hotplug IO region dynamically
it replaces a static complied in DSDT MMIO region
for CPU hotplug with one created at runtime
leaving only truly static CPU hotplug related ASL
bits in DSDT.
It also puts CPU_HOTPLUG_RESOURCE_DEVICE into
PCI0 scope and reserves resources from it,
preparing for dropping manual hole punching
in PCI0._CRS.

Later it also would make easier to reuse current
ACPI CPU hotplug on other targets.

Also later it would be possible to move remaining
CPU hotplug ASL methods into build_ssdt() and
add all CPU hotplug related AML into SSDT only
when CPU hotplug is enabled, further reducing
ACPI tables blob if CPU hotplug isn't used.

impl. detail:
Windows XP can't handle /BSODs/ OperationRegion
declaration in DSDT when variable from SSDT is used
for specifying its address/length and also when
Field declared in DSDT with OperationRegion from
SSDT if DSDT is being parsed before SSDT.
But it works just fine when referencing named
fields from another table. Hence OperationRegion
and Field declaration are moved to SSDT to make
XP based editions work.

PS:
Later Windows editions seem to be fine with above
conditions.
