329163cbe6 qemu-iothread: IOThread supports the GMainContext event loop
IOThread uses AioContext event loop and does not run a GMainContext.
Therefore,chardev cannot work in IOThread,such as the chardev is
used for colo-compare packets reception.

This patch makes the IOThread run the GMainContext event loop,
chardev and IOThread can work together.

626bba988a net/colo-compare.c: Adjust net queue pop order for performance
The packet_enqueue() use g_queue_push_tail() to
enqueue net packet, so it is more efficent way use
g_queue_pop_head() to get packet for compare.
That will improve the success rate of comparison.
In my test the performance of ftp put 1000M file

0522a959ae net/socket: Improve -net socket error reporting
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.

e1b24b649a net/socket: Don't treat odd socket type as SOCK_STREAM
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.

0c8f86ea98 net/rocker: Convert to realize()
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

that g_malloc() of 0 bytes returns null. So error checks for these
allocation failure are superfluous. Now, remove them entirely.

2527cb9109 ppc: drop caching ObjectClass from PowerPCCPUAlias
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.

c5354f54aa ppc: make cpu_model translation to type consistent
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.

fa98fbfcdf PPC: KVM: Support machine option to set VSMT mode
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.

cc7b35b169 spapr: fallback to raw mode if best compat mode cannot be set during CAS
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 152ef803ce,
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.

c449d8ba42 booke206: fix tlbnps for fixed size TLB
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
return directly the right tlbnps instead of computing it from non existing
field.

2e886fb391 ppc: spapr: Make VCPU ID handling private to SPAPR
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.

81210c2009 ppc: spapr: Rename cpu_dt_id to vcpu_id
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.

6d53657019 e500: Use cpu_index instead of vcpu_dt_id
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).
