It was in SaveState but now moved to MigrationState altogether, reverted
its meaning, then renamed to "send_configuration". Again, using
HW_COMPAT_2_3 for old PC/SPAPR machines, and accel_register_prop() for
xen_init().

Put it into MigrationState then we can use the properties to specify
whether to enable storing global state.
Removing global_state_set_optional() since now we can use HW_COMPAT_2_3
for x86/power, and AccelClass.global_props for Xen.

Introduce this new field for the accelerator classes so that each
specific accelerator in the future can register its own global
properties to be used further by the system. It works just like how the
old machine compatible properties do, but only tailored for
accelerators.
Introduce register_compat_props_array() for it. Export it so that it may
be used in other codes as well in the future.

We have HW_COMPAT_*, however that's only bound to machines, not other
things (like accelerators). Behind it, it was register_compat_prop()
that played the trick. Let's export the function for further use
outside HW_COMPAT_* magic.
Meanwhile, move it to qdev-properties.c where seems more proper (since
it'll be used not only in machine codes).

The q35 machine type currently lets the guest firmware select a 1MB, 2MB
or 8MB TSEG (basically, SMRAM) size. In edk2/OVMF, we use 8MB, but even
that is not enough when a lot of VCPUs (more than approx. 224) are
configured -- SMRAM footprint scales largely proportionally with VCPU
count.
Introduce a new property for "mch" called "extended-tseg-mbytes", which
expresses (in megabytes) the user's choice of TSEG (SMRAM) size.
Invent a new, QEMU-specific register in the config space of the DRAM
Controller, at offset 0x50, in order to allow guest firmware to query the
TSEG (SMRAM) size.
According to Intel Document Number 316966-002, Table 5-1 "DRAM Controller
Register Address Map (D0:F0)":
Warning: Address locations that are not listed are considered Intel
Reserved registers locations. Reads to Reserved registers may
return non-zero values. Writes to reserved locations may
cause system failures.
All registers that are defined in the PCI 2.3 specification,
but are not necessary or implemented in this component are
simply not included in this document. The
reserved/unimplemented space in the PCI configuration header
space is not documented as such in this summary.
Offsets 0x50 and 0x51 are not listed in Table 5-1. They are also not part
of the standard PCI config space header. And they precede the capability
list as well, which starts at 0xe0 for this device.
When the guest writes value 0xffff to this register, the value that can be
read back is that of "mch.extended-tseg-mbytes" -- unless it remains
0xffff. The guest is required to write 0xffff first (as opposed to a
read-only register) because PCI config space is generally not cleared on
QEMU reset, and after S3 resume or reboot, new guest firmware running on
old QEMU could read a guest OS-injected value from this register.
After reading the available "extended" TSEG size, the guest firmware may
actually request that TSEG size by writing pattern 11b to the ESMRAMC
register's TSEG_SZ bit-field. (The Intel spec referenced above defines
only patterns 00b (1MB), 01b (2MB) and 10b (8MB); 11b is reserved.)
On the QEMU command line, the value can be set with
-global mch.extended-tseg-mbytes=N
The default value for 2.10+ q35 machine types is 16. The value is limited
to 0xfff (4095) at the moment, purely so that the product (4095 MB) can be
stored to the uint32_t variable "tseg_size" in mch_update_smram(). Users
are responsible for choosing sensible TSEG sizes.
On 2.9 and earlier q35 machine types, the default value is 0. This lets
the 11b bit pattern in ESMRAMC.TSEG_SZ, and the register at offset 0x50,
keep their original behavior.
When "extended-tseg-mbytes" is nonzero, the new register at offset 0x50 is
set to that value on reset, for completeness.
PCI config space is migrated automatically, so no VMSD changes are
necessary.

This commit introduces a vhost-user device for SCSI. This is based
on the existing vhost-scsi implementation, but done over vhost-user
instead. It also uses a chardev to connect to the backend. Unlike
vhost-scsi (today), VMs using vhost-user-scsi can be live migrated.
To use it, start Qemu with a command line equivalent to:
qemu-system-x86_64 \
-chardev socket,id=vus0,path=/tmp/vus.sock \
-device vhost-user-scsi-pci,chardev=vus0,bus=pci.0,addr=...
A separate commit presents a sample application linked with libiscsi to
provide a backend for vhost-user-scsi.

We need to handle both registers and ITS tables. While
register handling is standard, ITS table handling is more
challenging since the kernel API is devised so that the
tables are flushed into guest RAM and not in vmstate buffers.
Flushing the ITS tables on device pre_save() is too late
since the guest RAM is already saved at this point.
Table flushing needs to happen when we are sure the vcpus
are stopped and before the last dirty page saving. The
right point is RUN_STATE_FINISH_MIGRATE but sometimes the
VM gets stopped before migration launch so let's simply
flush the tables each time the VM gets stopped.
For regular ITS registers we just can use vmstate pre_save()
and post_load() callbacks.

some memory is allocated and some structures are allocated.

Until recently, spapr used to allocate ICPState objects for the lifetime
of the machine. They would only be associated to vCPUs in xics_cpu_setup()
when plugging a CPU core.
Now that ICPState objects have the same lifecycle as vCPUs, it is
possible to associate them during realization.
This patch hence open-codes xics_cpu_setup() in icp_realize(). The vCPU
is passed as a property. Note that vCPU now needs to be realized first
for the IRQs to be allocated. It also needs to resetted before ICPState
realization in order to synchronize with KVM.
Since ICPState objects are freed when unrealized, xics_cpu_destroy() isn't
needed anymore and can be safely dropped.

Taking into account that qemu_set_irq() returns immediatly if its first
argument is NULL, icp_kvm_reset() largely duplicates icp_reset().
This patch introduces a reset() handler, so that the common logic can
be implemented in icp_reset() only.
While there we can also drop icp_kvm_realize() and icp_kvm_unrealize(). This
causes icp-kvm to be realized in icp_realize(), which sets icp->xics, but
it has no impact.

DRC objects have a get_name method which returns the DRC name generated
when the DRC is created. Replace that with a fixed spapr_drc_name()
function which generates the name on the fly from other information. This
means:
* We get rid of a method with only one implementation, and only local
callers
* We don't have to carry the name string around for the lifetime of the
DRC
* We use information added to the class structure to generate the name
in standard format, so we don't need an explicit switch on drc type
any more
We also eliminate the 'name' property; it's basically useless since the
only information in it can easily be deduced from other things.

DRC objects have attach & detach methods, but there's only one
implementation. Although there are some differences in its behaviour for
different DRC types, the overall structure is the same, so while we might
want different method implementations for some parts, we're unlikely to
want them for the top-level functions.
So, replace them with direct function calls.

There are 3 types of "indicator" associated with hotplug in the PAPR spec
the "allocation state", "isolation state" and "DR-indicator". The first
two are intimately tied to the various state transitions associated with
hotplug. The DR-indicator, however, is different and simpler.
It's basically just a guest controlled variable which can be used by the
guest to flag state or problems associated with a device. The idea is that
the hypervisor can use it to present information back on management
consoles (on some machines with PowerVM it may even control physical LEDs
on the machine case associated with the relevant device).
For that reason, there's only ever likely to be a single update
implementation so the set_indicator_state method isn't useful. Replace it
with a direct function call.
While we're there, make some small associated cleanups:
* PAPR doesn't use the term "indicator state", just "DR-indicator" and
the allocation state and isolation state are also considered "indicators".
Rename things to be less confusing
* Fold set_indicator_state() and rtas_set_indicator_state() into a single
rtas_set_dr_indicator() function.

DRC classes have an entity_sense method to determine (in a specific PAPR
sense) the presence or absence of a device plugged into a DRC. However,
we only have one implementation of the method, which explicitly tests for
different DRC types. This changes it to instead have different method
implementations for the two cases: "logical" and "physical" DRCs.
While we're at it, the entity sense method always returns RTAS_OUT_SUCCESS,
and the interesting value is returned via pass-by-reference. Simplify this
to directly return the value we care about

The big thing in this batch is a start on a substantial cleanup of the
pseries hotplug mechanisms, which were pretty confusing. For now
these shouldn't cause substantial behavioural changes, but I am hoping
these lead to clearer code and eventually to fixes for the bugs we
have in hotplug handling, particularly when hotplug and migration are
combined.
The remaining patches are mostly bugfixes.

MIDA (modified indirect data addressing) is an optional facility, and
we (currently) don't support it. Let's post an operand exception if
the guest tries to set it in the orb and a channel program check
if it is set in a ccw, as specified in the Principles of Operation.

This function was used in generating the device tree. However, now that
we have different QOM types for different DRC types we can easily store
the information we need in the class structure and avoid this specialized
lookup function.

Currently the sPAPRMachineState contains a list of sPAPRConfigureConnector
structures which store intermediate state for the ibm,configure-connector
RTAS call.
This was an attempt to separate this state from the core of the DRC state.
However the configure connector process is intimately tied to the DRC
model, so there's really no point trying to have two levels of interface
here.
Moving the configure-connector state into its corresponding DRC allows
removal of a number of helpers for maintaining the anciliary list.

* Change names to something less ludicrously verbose
* Now that we have QOM subclasses for the different DRC types, use a QOM
typename instead of a PAPR type value parameter
The latter allows removal of the get_type_shift() helper.

Currently we only have a single QOM type for all DRCs, but lots of
places where we switch behaviour based on the DRC's PAPR defined type.
This is a poor use of our existing type system.
So, instead create QOM subclasses for each PAPR defined DRC type. We
also introduce intermediate subclasses for physical and logical DRCs,
a division which will be useful later on.
Instead of being stored in the DRC object itself, the PAPR type is now
stored in the class structure. There are still many places where we
switch directly on the PAPR type value, but this at least provides the
basis to start to remove those.

These two methods only have one implementation, and the spec they're
implementing means any other implementation is unlikely, verging on
impossible.
So replace them with simple functions.

DRConnectorClass has a set_configured method, however:
* There is only one implementation, and only ever likely to be one
* There's exactly one caller, and that's (now) local
* The implementation is very straightforward
So abolish the method entirely, and just open-code what we need.

The DRConnectorClass includes a get_fdt method. However
* There's only one implementation, and there's only likely to ever be one
* Both callers are local to spapr_drc
* Each caller only uses one half of the actual implementation
So abolish get_fdt() entirely, and just open-code what we need.

Since the automatic cpuid-level code was introduced in commit
c39c0edf9bb3b968ba95484465a50c7b19f4aa3a ("target-i386: Automatically
set level/xlevel/xlevel2 when needed"), the CPU model tables just define
the default CPUID level code (set using "min-level"). Setting
"[x]level" forces CPUID level to a specific value and disable the
automatic-level logic.
But the PC compat code was not updated and the existing "[x]level"
compat properties broke compatibility for people using features that
triggered the auto-level code. To keep previous behavior, we should set
"min-[x]level" instead of "[x]level" on compat_props.
This was not a problem for most cases, because old machine-types don't
have full-cpuid-auto-level enabled. The only common use case it broke
was the CPUID[7] auto-level code, that was already enabled since the
first CPUID[7] feature was introduced (in QEMU 1.4.0).
This causes the regression reported at:
https://bugzilla.redhat.com/show_bug.cgi?id=1454641
Change the PC compat code to use "min-[x]level" instead of "[x]level" on
compat_props, and add new test cases to ensure we don't break this
again.
