When a LMB hot unplug starts, the current DRC LMB status is stored at
spapr->pending_dimm_unplugs QTAILQ. This queue isn't migrated, thus
if a migration occurs in the middle of a LMB unplug the
spapr_lmb_release callback will lost track of the LMB unplug progress.
This patch implements a new recover function spapr_recover_pending_dimm_state
that is used inside spapr_lmb_release to recover this DRC LMB release
status that is lost during the migration.

In pseries, a firmware abstraction called Dynamic Reconfiguration
Connector (DRC) is used to assign a particular dynamic resource
to the guest and provide an interface to manage configuration/removal
of the resource associated with it. In other words, DRC is the
'plugged state' of a device.
Before this patch, DRC wasn't being migrated. This causes
post-migration problems due to DRC state mismatch between source and
target. The DRC state of a device X in the source might
change, while in the target the DRC state of X is still fresh. When
migrating the guest, X will not have the same hotplugged state as it
did in the source. This means that we can't hot unplug X in the
target after migration is completed because its DRC state is not consistent.
https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1677552 is one
bug that is caused by this DRC state mismatch between source and
target.
To migrate the DRC state, we defined the VMStateDescription struct for
spapr_drc to enable the transmission of spapr_drc state in migration.
Not all the elements in the DRC state are migrated - only those
that can be modified by guest actions or device add/remove
operations:
- 'isolation_state', 'allocation_state' and 'indicator_state'
are involved in the DR state transition diagram from
PAPR+ 2.7, 13.4;
- 'configured', 'signalled', 'awaiting_release' and 'awaiting_allocation'
are needed in attaching and detaching devices;
- 'indicator_state' provides users with hardware state information.
These are the DRC elements that are migrated.
In this patch the DRC state is migrated for PCI, LMB and CPU
connector types. At this moment there is no support to migrate
DRC for the PHB (PCI Host Bridge) type.
In the 'realize' function the DRC is registered using vmstate_register,
similar to what hw/ppc/spapr_iommu.c does in 'spapr_tce_table_realize'.
This approach works because DRCs are bus-less and do not sit
on a BusClass that implements bc->get_dev_path, so as a fallback the
VMSD gets identified via "spapr_drc"/get_index(drc).

The pointer drc->detach_cb is being used as a way of informing
the detach() function inside spapr_drc.c which cb to execute. This
information can also be retrieved simply by checking drc->type and
choosing the right callback based on it. In this context, detach_cb
is redundant information that must be managed.
After the previous spapr_lmb_release change, no detach_cb_opaques
are being used by any of the three callbacks functions. This is
yet another information that is now unused and, on top of that, can't
be migrated either.
This patch makes the following changes:
- removal of detach_cb_opaque. the 'opaque' argument was removed from
the callbacks and from the detach() function of sPAPRConnectorClass. The
attribute detach_cb_opaque of sPAPRConnector was removed.
- removal of detach_cb from the detach() call. The function pointer
detach_cb of sPAPRConnector was removed. detach() now uses a
switch(drc->type) to execute the apropriate callback. To achieve this,
spapr_core_release, spapr_lmb_release and spapr_phb_remove_pci_device_cb
callbacks were made public to be visible inside detach().

The LMB DRC release callback, spapr_lmb_release(), uses an opaque
parameter, a sPAPRDIMMState struct that stores the current LMBs that
are allocated to a DIMM (nr_lmbs). After each call to this callback,
the nr_lmbs is decremented by one and, when it reaches zero, the callback
proceeds with the qdev calls to hot unplug the LMB.
Using drc->detach_cb_opaque is problematic because it can't be migrated in
the future DRC migration work. This patch makes the following changes to
eliminate the usage of this opaque callback inside spapr_lmb_release:
- sPAPRDIMMState was moved from spapr.c and added to spapr.h. A new
attribute called 'addr' was added to it. This is used as an unique
identifier to associate a sPAPRDIMMState to a PCDIMM element.
- sPAPRMachineState now hosts a new QTAILQ called 'pending_dimm_unplugs'.
This queue of sPAPRDIMMState elements will store the DIMM state of DIMMs
that are currently going under an unplug process.
- spapr_lmb_release() will now retrieve the nr_lmbs value by getting the
correspondent sPAPRDIMMState. A helper function called spapr_dimm_get_address
was created to fetch the address of a PCDIMM device inside spapr_lmb_release.
When nr_lmbs reaches zero and the callback proceeds with the qdev hot unplug
calls, the sPAPRDIMMState struct is removed from spapr->pending_dimm_unplugs.
After these changes, the opaque argument for spapr_lmb_release is now
unused and is passed as NULL inside spapr_del_lmbs. This and the other
opaque arguments can now be safely removed from the code.
As an additional cleanup made by this patch, the spapr_del_lmbs function
was merged with spapr_memory_unplug_request. The former was being called
only by the latter and both were small enough to fit one single function.

Unfortunately, 8149e29 "pseries: Enforce homogeneous threads-per-core"

Guests of the qemu machine type go through a feature negotiation process
known as "client architecture support" (CAS) during early boot. This does
a number of things, one of which is finding a CPU compatibility mode which
can be supported by both guest and host.
In fact the CPU negotiation is probably the single most complex part of the
CAS process, so this splits it out into a helper function. We've recently
made some mistakes in maintaining backward compatibility for old machine
types here. Splitting this out will also make it easier to fix this.
This also adds a possibly useful error message if the negotiation fails
(i.e. if there isn't a CPU mode that's suitable for both guest and host).

Currenty we do not have any RTAS event that is reported by the
event-scan interface. The existing events, RTAS_LOG_TYPE_EPOW and
RTAS_LOG_TYPE_HOTPLUG, are being reported by the check-exception
interface and, as such, marked as 'exception=true'.
Commit 79853e18d9, 'spapr_events: event-scan RTAS interface', added
the event_scan interface because the guest kernel requires it to
initialize other required interfaces. It is acting since then as
a stub because no events that would be reported by it were added
since then. However, the existence of the 'exception' boolean adds
an unnecessary load in the future migration of the pending_events,
sPAPREventLogEntry QTAILQ that hosts the pending RTAS events.
To make the code cleaner and ease the future migration changes, this
patch makes the following changes:
- remove the 'exception' boolean that filter these events. There is
nothing to filter since all events are reported by check-exception;
- functions rtas_event_log_queue, rtas_event_log_dequeue and
rtas_event_log_contains don't receive the 'exception' boolean
as parameter;
- event_scan function was simplified. It was calling
'rtas_event_log_dequeue(mask, false)' that was always returning
'NULL' because we have no events that are created with
exception=false, thus in the end it would execute a jump to
'out_no_events' all the time. The function now assumes that
this will always be the case and all the remaining logic were
deleted.
In the future, when or if we add new RTAS events that should
be reported with the event_scan interface, we can refer to
the changes made in this patch to add the event_scan logic
back.

unplugged ealier, thanks to a boolean flag in ICPState that we set when
enabling KVM_CAP_IRQ_XICS.
This could work because the lifecycle of all ICPState objects was the
same as the machine. Commit 5bc8d26de2 ("spapr: allocate the ICPState

pass a freshly allocated ICPState object (ie, with the flag unset) to
icp_kvm_cpu_setup().
This cause re-hotplug to fail with:
Unable to connect CPU8 to kernel XICS: Device or resource busy
Let's fix this by caching all the vCPU ids for which KVM_CAP_IRQ_XICS was
enabled. This also drops the now useless boolean flag from ICPState.

We want to track why a guest was shutdown; in particular, being able
to tell the difference between a guest request (such as ACPI request)
and host request (such as SIGINT) will prove useful to libvirt.
Since all requests eventually end up changing shutdown_requested in
vl.c, the logical change is to make that value track the reason,
rather than its current 0/1 contents.
Since command-line options control whether a reset request is turned
into a shutdown request instead, the same treatment is given to
reset_requested.
This patch adds an internal enum ShutdownCause that describes reasons
that a shutdown can be requested, and changes qemu_system_reset() to
pass the reason through, although for now nothing is actually changed
with regards to what gets reported. The enum could be exported via
QAPI at a later date, if deemed necessary, but for now, there has not
been a request to expose that much detail to end clients.
For the most part, we turn 0 into SHUTDOWN_CAUSE_NONE, and 1 into
SHUTDOWN_CAUSE_HOST_ERROR; the only specific case where we have enough
information right now to use a different value is when we are reacting
to a host signal. It will take a further patch to edit all call-sites
that can trigger a reset or shutdown request to properly pass in any
other reasons; this patch includes TODOs to point such places out.
qemu_system_reset() trades its 'bool report' parameter for a
'ShutdownCause reason', with all non-zero values having the same
effect; this lets us get rid of the weird #defines for VMRESET_*
as synonyms for bools.

This commit fixes a bug which causes the guest to hang. The bug was
observed upon a "receive overrun" (bit #6 of the ICR register)
interrupt which could be triggered post migration in a heavy traffic
environment. Even though the "receive overrun" bit (#6) is masked out
by the IMS register (refer to the log below) the driver still receives
an interrupt as the "receive overrun" bit (#6) causes the "Other" -
bit #24 of the ICR register - bit to be set as documented below. The
driver handles the interrupt and clears the "Other" bit (#24) but
doesn't clear the "receive overrun" bit (#6) which leads to an
infinite loop. Apparently the Windows driver expects that the "receive
overrun" bit and other ones - documented below - to be cleared when
the "Other" bit (#24) is cleared.
So to sum that up:
1. Bit #6 of the ICR register is set by heavy traffic
2. As a results of setting bit #6, bit #24 is set
3. The driver receives an interrupt for bit 24 (it doesn't receieve an
interrupt for bit #6 as it is masked out by IMS)
4. The driver handles and clears the interrupt of bit #24
5. Bit #6 is still set.
6. 2 happens all over again
The Interrupt Cause Read - ICR register:
The ICR has the "Other" bit - bit #24 - that is set when one or more
of the following ICR register's bits are set:
LSC - bit #2, RXO - bit #6, MDAC - bit #9, SRPD - bit #16, ACK - bit
#17, MNG - bit #18
This bug can occur with any of these bits depending on the driver's
behaviour and the way it configures the device. However, trying to
reproduce it with any bit other than RX0 is challenging and came to
failure as the drivers don't implement most of these bits, trying to
reproduce it with LSC (Link Status Change - bit #2) bit didn't succeed
too as it seems that Windows handles this bit differently.

We want to support real (i.e. not virtual) channel devices
even for guests that do not support MCSS-E (where guests may
see devices from any channel subsystem image at once). As all
virtio-ccw devices are in css 0xfe (and show up in the default
css 0 for guests not activating MCSS-E), we need an option to
squash both the virtio subchannels and e.g. passed-through
subchannels from their real css (0-3, or 0 for hosts not
activating MCSS-E) into the default css. This will be
exploited in a later patch.

According to section 2.1.2 of the virtio-1 specification:
"The device SHOULD set DEVICE_NEEDS_RESET when it enters an error state that
a reset is needed. If DRIVER_OK is set, after it sets DEVICE_NEEDS_RESET,
the device MUST send a device configuration change notification to the
driver."
Commit "f5ed36635d8f virtio: stop virtqueue processing if device is broken"
introduced a virtio_error() call that just does that:
- internally mark the device as broken
- set the DEVICE_NEEDS_RESET bit in the status
- send a configuration change notification
Unfortunately, virtio_notify_vector(), called by virtio_notify_config(),
returns right away when the device is marked as broken and the notification
isn't sent in this case.
The spec doesn't say whether a broken device can send notifications
in other situations or not. But since the driver isn't supposed to do
anything but to reset the device, it makes sense to keep the check in
virtio_notify_config().
Marking the device as broken AFTER the configuration change notification was
sent is enough to fix the issue.

is dictated by the pci bridge specification.

commit 33cd52b5d7 unset
cannot_instantiate_with_device_add_yet in TYPE_SYSBUS, making all
sysbus devices appear on "-device help" and lack the "no-user"
flag in "info qdm".
To fix this, we can set user_creatable=false by default on
TYPE_SYS_BUS_DEVICE, but this requires setting
user_creatable=true explicitly on the sysbus devices that
actually work with -device.
Fortunately today we have just a few has_dynamic_sysbus=1
machines: virt, pc-q35-*, ppce500, and spapr.
virt, ppce500, and spapr have extra checks to ensure just a few
device types can be instantiated:
* virt supports only TYPE_VFIO_CALXEDA_XGMAC, TYPE_VFIO_AMD_XGBE.
* ppce500 supports only TYPE_ETSEC_COMMON.
* spapr supports only TYPE_SPAPR_PCI_HOST_BRIDGE.
This patch sets user_creatable=true explicitly on those 4 device
classes.
Now, the more complex cases:
pc-q35-*: q35 has no sysbus device whitelist yet (which is a
separate bug). We are in the process of fixing it and building a
sysbus whitelist on q35, but in the meantime we can fix the
"-device help" and "info qdm" bugs mentioned above. Also, despite
not being strictly necessary for fixing the q35 bug, reducing the
list of user_creatable=true devices will help us be more
confident when building the q35 whitelist.
xen: We also have a hack at xen_set_dynamic_sysbus(), that sets
has_dynamic_sysbus=true at runtime when using the Xen
accelerator. This hack is only used to allow xen-backend devices
to be dynamically plugged/unplugged.
This means today we can use -device with the following 22 device
types, that are the ones compiled into the qemu-system-x86_64 and
qemu-system-i386 binaries:
* allwinner-ahci
* amd-iommu
* cfi.pflash01
* esp
* fw_cfg_io
* fw_cfg_mem
* generic-sdhci
* hpet
* intel-iommu
* ioapic
* isabus-bridge
* kvmclock
* kvm-ioapic
* kvmvapic
* SUNW,fdtwo
* sysbus-ahci
* sysbus-fdc
* sysbus-ohci
* unimplemented-device
* virtio-mmio
* xen-backend
* xen-sysdev
This patch adds user_creatable=true explicitly to those devices,
temporarily, just to keep 100% compatibility with existing
behavior of q35. Subsequent patches will remove
user_creatable=true from the devices that are really not meant to
user-creatable on any machine, and remove the FIXME comment from
the ones that are really supposed to be user-creatable. This is
being done in separate patches because we still don't have an
obvious list of devices that will be whitelisted by q35, and I
would like to get each device reviewed individually.

[ehabkost: Small changes at sysbus_device_class_init() comments]
Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>
cannot_instantiate_with_device_add_yet was introduced by commit
efec3dd631 to replace no_user. It was
supposed to be a temporary measure.
When it was introduced, we had 54
cannot_instantiate_with_device_add_yet=true lines in the code.
Today (3 years later) this number has not shrunk: we now have
57 cannot_instantiate_with_device_add_yet=true lines. I think it
is safe to say it is not a temporary measure, and we won't see
the flag go away soon.
Instead of a long field name that misleads people to believe it
is temporary, replace it a shorter and less misleading field:
user_creatable.
Except for code comments, changes were generated using the
following Coccinelle patch:

The Xen mapcache is able to create long term mappings, they are called
"locked" mappings. The third parameter of the xen_map_cache call
specifies if a mapping is a "locked" mapping.
>From the QEMU point of view there are two kinds of long term mappings:
[a] device memory mappings, such as option roms and video memory
[b] dma mappings, created by dma_memory_map & friends
After certain operations, ballooning a VM in particular, Xen asks QEMU
kindly to destroy all mappings. However, certainly [a] mappings are
present and cannot be removed. That's not a problem as they are not
affected by balloonning. The *real* problem is that if there are any
mappings of type [b], any outstanding dma operations could fail. This is
a known shortcoming. In other words, when Xen asks QEMU to destroy all
mappings, it is an error if any [b] mappings exist.
However today we have no way of distinguishing [a] from [b]. Because of
that, we cannot even print a decent warning.
This patch introduces a new "dma" bool field to MapCacheRev entires, to
remember if a given mapping is for dma or is a long term device memory
mapping. When xen_invalidate_map_cache is called, we print a warning if
any [b] mappings exist. We ignore [a] mappings.
Mappings created by qemu_map_ram_ptr are assumed to be [a], while
mappings created by address_space_map->qemu_ram_ptr_length are assumed
to be [b].
The goal of the patch is to make debugging and system understanding
easier.

9pfs: local: forbid client access to metadata (CVE-2017-7493)
Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
When using the mapped-file security mode, we shouldn't let the client mess
with the metadata. The current code already tries to hide the metadata dir
from the client by skipping it in local_readdir(). But the client can still
access or modify it through several other operations. This can be used to
escalate privileges in the guest.
Affected backend operations are:
- local_mknod()
- local_mkdir()
- local_open2()
- local_symlink()
- local_link()
- local_unlinkat()
- local_renameat()
- local_rename()
- local_name_to_path()
Other operations are safe because they are only passed a fid path, which
is computed internally in local_name_to_path().
This patch converts all the functions listed above to fail and return
EINVAL when being passed the name of the metadata dir. This may look
like a poor choice for errno, but there's no such thing as an illegal
path name on Linux and I could not think of anything better.
This fixes CVE-2017-7493.

The spec says:
Suspend: (PORT_SUSPEND) This field indicates whether or not the device
on this port is suspended. Setting this field causes the device to
suspend by not propagating bus traffic downstream. This field may be
reset by a request or by resume signaling from the device attached to
the port.
I can't find any specific statement like "the PORT_SUSPEND field is reset
automatically on remote wakeup", but without this patch, the only way to
reset it is via the ClearPortFeature request so the ".. or by resume
signaling from the device" clause is clearly not implemented on the remote
wakeup path.
The default xhci Windows driver does not issue the ClearPortFeature request
and suspended devices attached to a hub don't properly get out of the
suspended state. Interestingly, the default uhci Windows driver *does*
issue the ClearPortFeature request and does not exhibit this problem.

CPU and node it belongs to is specified by 'props' argument.
Patch doesn't remove old way of storing mapping in
numa_info[X].node_cpu as removing it at the same time
makes patch rather big. Instead it just mirrors mapping
in possible_cpus and follow up per target patches will

Originally CPU threads were by default assigned in
round-robin fashion. However it was causing issues in
guest since CPU threads from the same socket/core could
be placed on different NUMA nodes.
Commit fb43b73b (pc: fix default VCPU to NUMA node mapping)
fixed it by grouping threads within a socket on the same node
introducing cpu_index_to_socket_id() callback and commit
20bb648d (spapr: Fix default NUMA node allocation for threads)
reused callback to fix similar issues for SPAPR machine
even though socket doesn't make much sense there.
As result QEMU ended up having 3 default distribution rules
used by 3 targets /virt-arm, spapr, pc/.
In effort of moving NUMA mapping for CPUs into possible_cpus,
generalize default mapping in numa.c by making boards decide
on default mapping and let them explicitly tell generic
numa code to which node a CPU thread belongs to by replacing
cpu_index_to_socket_id() with @cpu_index_to_instance_props()
which provides default node_id assigned by board to specified
cpu_index.

Currently cpu_index is implicitly auto assigned during
cpu.realize() time cpu_exec_realizefn()->cpu_list_add().
It happens to match index in possible_cpus so take
control over it and make board initialize cpu_index
to possible_cpus index explicitly. It will at least
document that board is in control of it and when
'-device cpu' support comes it will keep cpu_index
stable regardless of order cpus are created so it won't
break migration.
Within this series it will be used for internal
conversion from storing cpu_index based NUMA node
bitmaps to property based mapping with possible_cpus,
And will allow map cpu_index to a CPU entry in

When there are more nodes than available memory to put the minimum
allowed memory by node, all the memory is put on the last node.
This is because we put (ram_size / nb_numa_nodes) &
~((1 << mc->numa_mem_align_shift) - 1); on each node, and in this
case the value is 0. This is particularly true with pseries,
as the memory must be aligned to 256MB.
To avoid this problem, this patch uses an error diffusion algorithm [1]
to distribute equally the memory on nodes.
We introduce numa_auto_assign_ram() function in MachineClass
to keep compatibility between machine type versions.
The legacy function is used with pseries-2.9, pc-q35-2.9 and
pc-i440fx-2.9 (and previous), the new one with all others.

A radix guest can now be booted in pseries tcg mode by specifying:

Note that we assume hash, that is we allocate a hpt, until a guest tells
us otherwise via a H_REGISTER_PROCESS_TABLE call with radix specified - in
which case we free the hpt. If we were right and the guest is hash then
there's nothing for us to do.

to choose determine how address translation is performed. Currently these
bits in the LPCR are only set for the cpu which handles the H_CALL, however
they need to be set for all cpus for that guest as address translation
cannot be performed differently on a per cpu basis.
Update the H_CALL handler to set these bits in the LPCR correctly for all
cpus of the guest.
Note it is the reponsibility of the guest to ensure that any secondary cpus
are suspended when the H_CALL is made and thus we can safely update these

QEMU does not preserve these bits, so migrating (or otherwise saving

Clearing the P bit has no effect, because the kernel will set it based

Today, when a PowerNV guest runs, it uses the sensor definitions of
the BMC simulator to populate the device tree. But an external IPMI
BMC could also be used and, in that case, it is not (yet) possible to
retrieve the sensor list. Generating the OEM SEL event for shutdown or
reboot also does not make sense as it should be generated on the BMC
side.
This change allows a guest to use an 'ipmi-bmc-extern' backend to the
'isa-ipmi-bt' device and a 'chardev' for transport such as :
-chardev socket,id=ipmi0,host=localhost,port=9002,reconnect=10 \
-device ipmi-bmc-extern,id=bmc0,chardev=ipmi0 \
-device isa-ipmi-bt,bmc=bmc0,irq=10

Since 2.7 commit (b2a575a Add optionrom compatible with fw_cfg DMA version)
regressed migration during firmware exection time by
abusing fwcfg.dma_enabled property to decide loading
dma version of option rom AND by mistake disabling DMA
for 2.6 and earlier globally instead of only for option rom.
so 2.6 machine type guest is broken when it already runs
firmware in DMA mode but migrated to qemu-2.7(pc-2.6)
at that time;
a) qemu-2.6:pc2.6 (fwcfg.dma=on,firmware=dma,oprom=ioport)
b) qemu-2.7:pc2.6 (fwcfg.dma=off,firmware=ioport,oprom=ioport)
to: a b
from
a OK FAIL
b OK OK
So we currently have broken forward migration from
qemu-2.6 to qemu-2.[789] that however could be fixed
for 2.10 by re-enabling DMA for 2.[56] machine types
and allowing dma capable option rom only since 2.7.
As result qemu should end up with:
c) qemu-2.10:pc2.6 (fwcfg.dma=on,firmware=dma,oprom=ioport)
to: a b c
from
a OK FAIL OK
b OK OK OK
c OK FAIL OK
where forward migration from qemu-2.6 to qemu-2.10 should
work again leaving only qemu-2.[789]:pc-2.6 broken.

Our current ACPI table generation code limits the placement of ACPI
tables to 32-bit addressable memory, in order to be able to emit the
root pointer (RSDP) and root table (RSDT) using table types from the
ACPI 1.0 days.
Since ARM was not supported by ACPI before version 5.0, it makes sense
to lift this restriction. This is not crucial for mach-virt, which is
guaranteed to have some memory available below the 4 GB mark, but it
is a nice to have for QEMU machines that do not have any 32-bit
addressable memory, which is not uncommon for real world 64-bit ARM
systems.
Since we already emit a version of the RSDP root pointer that has a
secondary 64-bit wide address field for the 64-bit root table (XSDT),
all we need to do is replace the RSDT generation with the generation
of an XSDT table, and use a different slot in the FADT table to refer
to the DSDT.

To ensure that we do not keep any 3270 sockets where the client is not
connected anymore, we send a packet with the timing mark option after
ten minutes of client inactivity. If the client does not answer it,
then the socket will be closed automatically.
This helps to ensure that there is no half-open situation on the 3270
socket.

The OpenRISC architecture has the Power Management Register (PMR)
special purpose register to manage cpu power states. The interesting
modes are:
* Doze Mode (DME) - Stop cpu except timer & pic - wake on interrupt
* Sleep Mode (SME) - Stop cpu and all units - wake on interrupt
* Suspend Model (SUME) - Stop cpu and all units - wake on reset
The linux kernel will set DME when idle.
This patch implements the PMR SPR and halts the qemu cpu when there is a
change to DME or SME. This means that openrisc qemu in no longer peggs
a host cpu at 100%.
In order for this to work we need to kick the CPU when timers are
expired. Update the cpu timer to kick the cpu upon each timer event.

This patch enables 8-byte writes and reads to VFIO. Such implemention
is already done but it's missing the 'case' to handle such accesses in
both vfio_region_write and vfio_region_read and the MemoryRegionOps:
impl.max_access_size and impl.min_access_size.
After this patch, 8-byte writes such as:
qemu_mutex_lock locked mutex 0x10905ad8
vfio_region_write (0001:03:00.0:region1+0xc0, 0x4140c, 4)
vfio_region_write (0001:03:00.0:region1+0xc4, 0xa0000, 4)
qemu_mutex_unlock unlocked mutex 0x10905ad8
goes like this:
qemu_mutex_lock locked mutex 0x10905ad8
vfio_region_write (0001:03:00.0:region1+0xc0, 0xbfd0008, 8)

Sets valid.max_access_size and valid.min_access_size to ensure safe
8-byte accesses to vfio. Today, 8-byte accesses are broken into pairs
of 4-byte calls that goes unprotected:
qemu_mutex_lock locked mutex 0x10905ad8
vfio_region_write (0001:03:00.0:region1+0xc0, 0x2020c, 4)
qemu_mutex_unlock unlocked mutex 0x10905ad8
qemu_mutex_lock locked mutex 0x10905ad8
vfio_region_write (0001:03:00.0:region1+0xc4, 0xa0000, 4)
qemu_mutex_unlock unlocked mutex 0x10905ad8
which occasionally leads to:
qemu_mutex_lock locked mutex 0x10905ad8
vfio_region_write (0001:03:00.0:region1+0xc0, 0x2030c, 4)
qemu_mutex_unlock unlocked mutex 0x10905ad8
qemu_mutex_lock locked mutex 0x10905ad8
vfio_region_write (0001:03:00.0:region1+0xc0, 0x1000c, 4)
qemu_mutex_unlock unlocked mutex 0x10905ad8
qemu_mutex_lock locked mutex 0x10905ad8
vfio_region_write (0001:03:00.0:region1+0xc4, 0xb0000, 4)
qemu_mutex_unlock unlocked mutex 0x10905ad8
qemu_mutex_lock locked mutex 0x10905ad8
vfio_region_write (0001:03:00.0:region1+0xc4, 0xa0000, 4)
qemu_mutex_unlock unlocked mutex 0x10905ad8
causing strange errors in guest OS. With this patch, such accesses
are protected by the same lock guard:
qemu_mutex_lock locked mutex 0x10905ad8
vfio_region_write (0001:03:00.0:region1+0xc0, 0x2000c, 4)
vfio_region_write (0001:03:00.0:region1+0xc4, 0xb0000, 4)
qemu_mutex_unlock unlocked mutex 0x10905ad8
This happens because the 8-byte write should be broken into 4-byte
writes by memory.c:access_with_adjusted_size() in order to be under
the same lock. Today, it's done in exec.c:address_space_write_continue()
which was able to handle only 4 bytes due to a zero'ed
valid.max_access_size (see exec.c:memory_access_size()).

When driving QEMU from the outside, we have basically no chance to
determine how quickly the guest OS picks up key events, so we usually
have to limit ourselves to very slow keyboard presses to make sure
the guest always has enough chance to pick them up.
This patch adds a trace events when the keyboarde queue is drained.
An external driver can use that as hint that new keys can be pressed.

This updates the FADT generated for x86/64 machine types from Revision 1 to 3. (Based on ACPI standard 2.0 instead of 1.0) The intention is to expose the reset register information to guest operating systems which require it, specifically OS X/macOS. Revision 1 FADTs do not contain the fields relating to the reset register.
The new layout and contents remains backwards-compatible with operating systems which only support ACPI 1.0, as the existing fields are not modified by this change, as the 64-bit and 32-bit variants are allowed to co-exist according to the ACPI 2.0 standard. No regressions became apparent in tests with a range of Windows (XP-10) and Linux versions.
The BIOS tables test suite's FADT checksum test has also been updated to reflect the new FADT layout and content.

virtio-scsi-pci device, e.g.:
qemu-system-s390x -nographic -enable-kvm -device virtio-scsi-pci \
-drive file=/tmp/disk.dat,if=none,id=d1,format=raw \
-device scsi-cd,drive=d1,bootindex=1
The problem is that the code in s390_gen_initial_iplb() currently assumes
that all SCSI devices are also CCW devices, which is not the case for
virtio-scsi-pci of course. Fix it by adding an appropriate check for
TYPE_CCW_DEVICE here.

LOADPARM has two copies:
1. in SCP Information Block
2. in IPL Information Parameter Block
So, update SCLP intrinsics now. We always store LOADPARM in SCP
information block even if we don't have a valid IPL Information
Parameter Block.

Insert the LOADPARM value to the IPL Information Parameter Block.
An IPL Information Parameter Block is created when "bootindex" is
specified for a device. If a user specifies "loadparm=", then we
store the loadparm value in the created IPIB for that boot device.

In order to specify the LOADPARM value one may now add ",loadparm=xxx"
parameter to the "-machine s390-ccw-virtio" option.
The property setter will normalize and check the value provided much
like the way the HMC does.
The value is stored, but not used at the moment.

Here's a respind of my first pull request for qemu-2.10, consisting of
assorted patches which have accumulated while qemu-2.9 stabilized.
Highlights are:
* Rework / cleanup of the XICS interrupt controller
* Substantial improvement to the 'powernv' machine type
- Includes an MMIO XICS version
* POWER9 support improvements
- POWER9 guests with KVM
- Partial support for POWER9 guests with TCG
* IOMMU and VFIO improvements
* Assorted minor changes
There are several IPMI patches here that aren't usually in my area of
maintenance, but there isn't a regular maintainer and these patches
are for the benefit of the powernv machine type.
This pull request supersedes my 2017-04-26 pull request. This new set
fixes a bug in one of the aforementioned IPMI patches which caused
clang sanitizer failures (and may have crashed on some libc / host
versions).

Skiboot, the firmware for the PowerNV platform, expects the BMC to
provide some specific IPMI sensors. These sensors are exposed in the
device tree and their values are updated by the firmware at boot time.
Sensors of interest are :
"FW Boot Progress"
"Boot Count"
As such a device is defined on the command line, we can only detect
its presence at reset time.
