pactkets of the primary
Remove the task which check old packet in the comparing thread,
then use IOthread context timer to handle it.
Process pactkets in the IOThread which arrived over the socket.
we use iothread_get_g_main_context to create a new g_main_loop in
the IOThread.then the packets from the primary and the secondary
are processed in the IOThread.
Finally remove the colo-compare thread using the IOThread instead.

When -net socket fails, it first reports a specific error, then
a generic one, like this:
$ ./x86_64-softmmu/qemu-system-x86_64 -net socket,mcast=230.0.0.1:1234,listen
qemu-system-x86_64: -net socket,mcast=230.0.0.1:1234,listen: exactly one of listen=, connect=, mcast= or udp= is required
qemu-system-x86_64: -net socket,mcast=230.0.0.1:1234,listen: Device 'socket' could not be initialized
Convert net_socket_*_init() to Error to get rid of the superfluous second
error message. After the patch, the effect like this:
$ ./x86_64-softmmu/qemu-system-x86_64 -net socket,mcast=230.0.0.1:1234,listen
qemu-system-x86_64: -net socket,mcast=230.0.0.1:1234,listen: exactly one of listen=, connect=, mcast= or udp= is requireda
This also fixes a few silent failures to report an error.

In net_socket_fd_init(), the 'default' case is odd: it warns,
then continues as if the socket type was SOCK_STREAM. The
comment explains "this could be a eg. a pty", but that makes
no sense. If @fd really was a pty, getsockopt() would fail
with ENOTSOCK. If @fd was a socket, but neither SOCK_DGRAM nor
SOCK_STREAM. It should not be treated as if it was SOCK_STREAM.
Turn this case into an Error. If there is a genuine reason to
support something like SOCK_RAW, it should be explicitly
handled.

The rocker device still implements the old PCIDeviceClass .init()
instead of the new .realize(). All devices need to be converted to
.realize().
.init() reports errors with fprintf() and return 0 on success, negative
number on failure. Meanwhile, when -device rocker fails, it first report
a specific error, then a generic one, like this:
$ x86_64-softmmu/qemu-system-x86_64 -device rocker,name=qemu-rocker
rocker: name too long; please shorten to at most 9 chars
qemu-system-x86_64: -device rocker,name=qemu-rocker: Device initialization failed
Now, convert it to .realize() that passes errors to its callers via its
errp argument. Also avoid the superfluous second error message. After
the patch, effect like this:
$ x86_64-softmmu/qemu-system-x86_64 -device rocker,name=qemu-rocker

Memory allocation functions like world_alloc, desc_ring_alloc etc,
they are all wrappers around g_malloc, g_new etc. But g_malloc and
similar functions doesn't return null. Because they ignore the fact
that g_malloc() of 0 bytes returns null. So error checks for these
allocation failure are superfluous. Now, remove them entirely.

Move the calculation of a CPU's VCPU ID out of the generic PPC code
(ppc_cpu_realizefn()) and into sPAPR specific code
(spapr_cpu_core_realize()) where it belongs.
Unfortunately, due to the way things are ordered, we still need to
default the VCPU ID in ppc_cpu_realizfn() but at least doing that
doesn't require any interaction with sPAPR.

Caching there practically doesn't give any benefits
and that at slow path druring querying supported CPU list.
But it introduces non conventional path of where from
comes used CPU type name (kvm_ppc_register_host_cpu_type).
Taking in account that kvm_ppc_register_host_cpu_type()
fixes up models the aliases point to, it's sufficient to
make ppc_cpu_class_by_name() translate cpu alias to
correct cpu type name.
So drop PowerPCCPUAlias::oc field + ppc_cpu_class_by_alias()
and let ppc_cpu_class_by_name() do conversion to cpu type name,
which simplifies code a little bit saving ~20LOC and trouble
wondering why ppc_cpu_class_by_alias() is necessary.

alias pointing to another alias forces lookup code to

Drop this nonsence and make each alias point to cpu model
that has corresponding CPU type. It will allow to drop
recurrsion in cpu model translation code and actually
make ppc_cpu_aliases[] content use PowerPCCPUAlias
fields properly
(i.e. alias goes into .alias and model goes into .model)
While at it add TODO defines around aliases that point to

PPC handles -cpu FOO rather incosistently,
i.e. it does case-insensitive matching of FOO to
a CPU type (see: ppc_cpu_compare_class_name) but
handles alias names as case-sensitive, as result:
# qemu-system-ppc64 -M mac99 -cpu g3
qemu-system-ppc64: unable to find CPU model ' kN�U'
# qemu-system-ppc64 -cpu 970MP_V1.1
qemu-system-ppc64: Unable to find sPAPR CPU Core definition
while
# qemu-system-ppc64 -M mac99 -cpu G3
# qemu-system-ppc64 -cpu 970MP_v1.1
start up just fine.
Considering we can't take case-insensitive matching away,
make it case-insensitive for all alias/type/core_type
lookups.
As side effect it allows to remove duplicate core types
which are the same except of using different cased letters in name.

KVM now allows writing to KVM_CAP_PPC_SMT which has previously been
read only. Doing so causes KVM to act, for that VM, as if the host's
SMT mode was the given value. This is particularly important on Power
9 systems because their default value is 1, but they are able to
support values up to 8.
This patch introduces a way to control this capability via a new
machine property called VSMT ("Virtual SMT"). If the value is not set
on the command line a default is chosen that is, when possible,
compatible with legacy systems.
Note that the intialization of KVM_CAP_PPC_SMT has changed slightly
because it has changed (in KVM) from a global capability to a
VM-specific one. This won't cause a problem on older KVMs because VM
capabilities fall back to global ones.

KVM PR doesn't allow to set a compat mode. This causes ppc_set_compat_all()
to fail and we return H_HARDWARE to the guest right away.
This is excessive: even if we favor compat mode since commit 152ef803ceb19,
we should at least fallback to raw mode if the guest supports it.
This patch modifies cas_check_pvr() so that it also reports that the real
PVR was found in the table supplied by the guest. Note that this is only
makes sense if raw mode isn't explicitely disabled (ie, the user didn't
set the machine "max-cpu-compat" property). If this is the case, we can
simply ignore ppc_set_compat_all() failures, and let the guest run in raw
mode.

This NVRAM device registers RTAS calls during its realize function
and thus can only be used once - and that's internally from spapr.c.
So let's mark the device with user_creatable = false to avoid that
the users can crash their QEMU this way.

Make these device models available outside ppc405_uc.c for reuse in
460EX emulation. They are left in their current place for now because
they are used mostly unchanged and I'm not sure these correctly model

This device appears in other SoCs as well not just in 405 ones and
subsequent patches will modify it, so move it out of ppc405_uc.c in
preparation

This replaces g_malloc() with spapr_tce_alloc_table() as this is
the standard way of allocating tables and this allows moving the table
back to KVM when unplugging a VFIO PCI device and VFIO TCE acceleration
support is not present in the KVM.
Although spapr_tce_alloc_table() is expected to fail with EBUSY
if called when previous fd is not closed yet, in practice we will not
see it because cap_spapr_vfio is false at the moment.

Some OS don't populate the TSIZE field when using a fixed size TLB which result
in a 1KB TLB. When the TLB is a fixed size TLB the TSIZE field should be
ignored.
Fix this wrong behavior with MAV 2.0.

This fixes booke206_tlbnps for MAV 2.0 by checking the MMUCFG register and

The concept of a VCPU ID that differs from the CPU's index
(cpu->cpu_index) exists only within SPAPR machines so, move the
functions ppc_get_vcpu_id() and ppc_get_cpu_by_vcpu_id() into spapr.c
and rename them appropriately.

This field actually records the VCPU ID used by KVM and, although the
value is also used in the device tree it is primarily the VCPU ID so
rename it as such.

The e500 platform code uses the function ppc_get_vcpu_dt_id() to get
an id to put in its device tree. Which seems like it makes sense, but
ppc_get_vcpu_dt_id() is actually badly named - it only differs from
cpu_index in cases where you're running on KVM HV and the host's
number of threads differs from the guests. Since KVM HV only supports
PAPR, not e500, it doesn't make sense to use it here.
Simply use the cpu_index instead (which is 'i' in this context
because qemu_get_cpu(i) returns the cpu with cpu_index == i).
