1.0 does not requires physically-contiguous pages layout for a
virtqueue. So we could not infer avail and used from desc. This means
we need to migrate vring.avail and vring.used when host support virtio
1.0. This fixes malfunction of virtio 1.0 device after migration.

The Linux fec driver needs at least basic phy support to probe and work.
The current qemu mcf_fec emulation has no support for the reading or
writing of the MDIO lines to access an attached phy.
This code adds a very simple set of register results for a fixed phy
setup - very similar to that used on an m5208evb board. This is enough
to probe and identify an emulated attached phy.

W10 insider has a bug where it ignores CPUID level and interprets
CPUID.(EAX=07H, ECX=0H) incorrectly, because CPUID in fact returned
CPUID.(EAX=04H, ECX=0H); this resulted in execution of unsupported
instructions.
While it's a Windows bug, there is no reason to emulate incorrect level.
I used http://instlatx64.atw.hu/ as a source of CPUID and checked that
it matches Penryn Xeon X5472, Westmere Xeon W3520, SandyBridge i5-2540M,
and Haswell i5-4670T.
kvm64 and qemu64 were bumped to 0xD to allow all available features for
them (and to avoid the same Windows bug).

Thanks to the last patch, pc_cmos_init() doesn't need the (optional)
board-default FDC any longer as an input parameter. Update
pc_basic_device_init() not to hand it back to pc_init1() / pc_q35_init(),
and update the latter not to carry the FDC to pc_cmos_init(). This
simplifies the code.

If the signal is sampled high, this indicates that the system is
strapped to the "No Reboot" mode (ICH9 will disable the TCO Timer system
reboot feature). The status of this strap is readable via the NO_REBOOT
bit (CC: offset 0x3410:bit 5).
The NO_REBOOT bit is set when SPKR pin on ICH9 is sampled high. This bit
may be set or cleared by software if the strap is sampled low but may
not override the strap when it indicates "No Reboot".
This patch implements the logic where hardware has ability to set SPKR
pin through a property named "noreboot" and it's sampled high by
default.

target-i386: avoid overflow in the tsc-frequency property
i386: Introduce ARAT CPU feature
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
When supporting CPU hot removal by parking the vCPU fd and reusing
it during hotplug again, there can be cases where we try to reenable
KVM_CAP_IRQ_XICS CAP for the vCPU for which it was already enabled.
Introduce a boolean member in ICPState to track this and don't
reenable the CAP if it was already enabled earlier.
Re-enabling this CAP should ideally work, but currently it results in
kernel trying to create and associate ICP with this vCPU and that
fails since there is already an ICP associated with it. Hence this
patch is needed to work around this problem in the kernel.
This change allows CPU hot removal to work for sPAPR.

Add support for ibm,lrdr-capacity since this is needed by the guest
kernel to know about the possible hot-pluggable CPUs and Memory. With
this, pseries kernels will start reporting correct maxcpus in
/sys/devices/system/cpu/possible.

The sPAPRMachineState structure includes an entry_point field containing
the initial PC value for starting the machine, even though this always has
the value 0x100.
I think this is a hangover from very early versions which bypassed the
firmware when using -kernel. In any case it has no function now, so remove
it.

The ram_limit field was imported from sPAPREnvironment where it predates
the machine's ram size being available generically from machine->ram_size.
Worse, the existing code was inconsistent about where it got the ram size
from. Sometimes it used spapr->ram_limit, sometimes the global 'ram_size'
and sometimes a local 'ram_size' masking the global.
This cleans up the code to consistently use machine->ram_size, eliminating
spapr->ram_limit in the process.

The code for -machine pseries maintains a global sPAPREnvironment structure
which keeps track of general state information about the guest platform.
This predates the existence of the MachineState structure, but performs
basically the same function.
Now that we have the generic MachineState, fold sPAPREnvironment into
sPAPRMachineState, the pseries specific subclass of MachineState.
This is mostly a matter of search and replace, although a few places which
relied on the global spapr variable are changed to find the structure via
qdev_get_machine().

As our APICs are emulated, it's fine to expose this feature to guests,
at least when asking for KVM host features or with CPU types that

not known, but reports can be found that it's at least available since

This interface provides some registers within a 32-byte range and can be
acessed through PCI-to-LPC bridge interface (PMBASE + 0x60).
It's commonly used as a watchdog timer to detect system lockups through
SMIs that are generated -- if TCO_EN bit is set -- on every timeout. If
NO_REBOOT bit is not set in GCS (General Control and Status register),
the system will be resetted upon second timeout if TCO_RLD register
wasn't previously written to prevent timeout.
This patch adds support to TCO watchdog logic and few other features
like mapping NMIs to SMIs (NMI2SMI_EN bit), system intruder detection,
etc. are not implemented yet.

On ARM, commit ac9d32e396 postponed the
memory preparation for boot until the machine init done notifier. This
has for consequence to insert ROM at machine init done time.
However the rom_load_all function stayed called before the ROM are
inserted. As a consequence the rom_load_all function does not do
everything it is expected to do, on ARM.
It currently registers the ROM reset notifier but does not iterate through
the registered ROM list. the isrom field is not set properly. This latter
is used to report info in the monitor and also to decide whether the
rom->data can be freed on ROM reset notifier.
To fix that regression the patch moves the rom_load_all call after
machine init done. We also take the opportunity to rename the rom_load_all
function into rom_check_and_resgister_reset() and integrate the
rom_load_done in it.

device. The T5 hardware has a bug in it where it reports a Pending Interrupt
Bit Array Offset of 0x8000 for its SR-IOV Virtual Functions instead
of the 0x1000 that the hardware actually uses internally. As the hardware
doesn't return the correct pba_offset value, add a quirk to instead
return a hardcoded value of 0x1000 when a Chelsio T5 VF device is

This bug has been fixed in the Chelsio's next chip series T6 but there are

Including qemu-common.h from other header files is generally a bad
idea, because it means it's very easy to end up with a circular
dependency. For instance, if we wanted to include memory.h from
qom/cpu.h we'd end up with this loop:
memory.h -> qemu-common.h -> cpu.h -> cpu-qom.h -> qom/cpu.h -> memory.h
Remove the include from memory.h. This requires us to fix up a few
other files which were inadvertently getting declarations indirectly
through memory.h.
The biggest change is splitting the fprintf_function typedef out
into its own header so other headers can get at it without having
to include qemu-common.h.

The sysbus_get_fw_dev_path() function formats OpenFirmware device path
nodes ("driver-name@unit-address") for sysbus devices. The first choice
for "unit-address" is the base address of the device's first MMIO region.
The second choice is its first IO port.
However, if two sysbus devices with the same "driver-name" lack both MMIO
and PIO resources, then there is no good way to distinguish them based on
their OFW nodes, because in this case unit-address is omitted completely
for both devices. An example is TYPE_PXB_HOST ("pxb-host").
For the sake of such devices, introduce the explicit_ofw_unit_address()
"virtual member function". With this function, each sysbus device in the
same SysBusDeviceClass can state its own address.

Excessive virtio_balloon inflation can cause invocation of OOM-killer,
when Linux is under severe memory pressure. Various mechanisms are
responsible for correct virtio_balloon memory management. Nevertheless it
is often the case that these control tools does not have enough time to
react on fast changing memory load. As a result OS runs out of memory and
invokes OOM-killer. The balancing of memory by use of the virtio balloon
should not cause the termination of processes while there are pages in the
balloon. Now there is no way for virtio balloon driver to free memory at
the last moment before some process get killed by OOM-killer.
This does not provide a security breach as balloon itself is running
inside Guest OS and is working in the cooperation with the host. Thus
some improvements from Guest side should be considered as normal.
To solve the problem, introduce a virtio_balloon callback which is
expected to be called from the oom notifier call chain in out_of_memory()
function. If virtio balloon could release some memory, it will make the
system return and retry the allocation that forced the out of memory
killer to run.
This behavior should be enabled if and only if appropriate feature bit
is set on the device. It is off by default.
This functionality was recently merged into vanilla Linux.

qdev_init() is a wrapper around setting property "realized" to true,
plus error handling that passes errors to qerror_report_err().
qerror_report_err() is a transitional interface to help with
converting existing monitor commands to QMP. It should not be used
elsewhere.
All code has been modernized to avoid qdev_init() and its
inappropriate error handling. We can finally drop it.

The enum string table parameters in various QOM/QAPI methods
are declared 'const char *strings[]'. This results in const
warnings if passed a variable that was declared as
static const char * const strings[] = { .... };
Add the extra const annotation to the parameters, since
neither the string elements, nor the array itself should
ever be modified.

We use vhostforce to enable vhost even if Guests don't have MSI-X
support and we fall back to QEMU virtio-net.
This gives a very small performance gain, but the disadvantage
is that guest now controls which virtio code is running
(qemu or vhost) so our attack surface is doubled.
This patch will enable vhost unconditionally whenever it's requested.
For compatibility, enable vhost when vhostforce is set, as well.

When H_SMRAME is 1, low memory at 0xa0000 is left alone by
SMM, and instead the chipset maps the 0xa0000-0xbffff window at
0xfeda0000-0xfedbffff. This affects both the "non-SMM" view controlled
by D_OPEN and the SMM view controlled by G_SMRAME, so add two new
MemoryRegions and toggle the enabled/disabled state of all four

Remove cpu_smm_register and cpu_smm_update. Instead, each CPU

This region is exported at /machine/smram. It is "empty" if
SMRAME=0 and points to SMRAM if SMRAME=1. The CPU will
enable/disable it as it enters or exits SMRAM.
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.

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.

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.

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.

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.

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.

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.
See docs/specs/ppc-spapr-hotplug.txt for a complete description of

Namely, for calls where a "work area" buffer is used to pass
around arbitrary fields/data.

This interface allows a guest to control various platform/device
sensors. Initially, we only implement support necessary to control
sensors that are required for hotplug: DR connector indicators/LEDs,
resource allocation state, and resource isolation state.
See docs/specs/ppc-spapr-hotplug.txt for a complete description of
this interface.

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.

The check "liobn & 0xFFFFFFFF00000000ULL" in spapr_tce_find_by_liobn()
is completely useless since liobn is only declared as an uint32_t
parameter. Fix this by using target_ulong instead (this is what most

be used from other parts of QEMU such as VFIO DDW (dynamic DMA window)

We are going to have multiple DMA windows per PHB and we want them to
migrate so we need a predictable way of assigning LIOBNs.
This introduces a macro which makes up a LIOBN from fixed prefix,
PHB index (unique PHB id) and window number.
This introduces a SPAPR_PCI_DMA_WINDOW_NUM() to know the window number
from LIOBN. It is used to distinguish the default 32bit windows from
dynamic windows and avoid picking default DMA window properties from
a wrong TCE table.

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.
