57df0dff1a qapi: Extend -compat to set policy for unstable interfaces
New option parameters unstable-input and unstable-output set policy
for unstable interfaces just like deprecated-input and
deprecated-output set policy for deprecated interfaces (see commit
6dd75472d5 "qemu-options: New -compat to set policy for deprecated
interfaces").  This is intended for testing users of the management
interfaces.  It is experimental.

For now, this covers only syntactic aspects of QMP, i.e. stuff tagged
with feature 'unstable'.  We may want to extend it to cover semantic
aspects, or the command line.

Note that there is no good way for management application to detect
presence of these new option parameters: they are not visible output
of query-qmp-schema or query-command-line-options.  Tolerable, because
it's meant for testing.  If running with -compat fails, skip the test.

c868876043 qapi: Generalize enum member policy checking
The code to check enumeration value policy can see special feature
flag 'deprecated' in QEnumLookup member flags[value].  I want to make
feature flag 'unstable' visible there as well, so I can add policy for
it.

Instead of extending flags[], replace it by @special_features (a
bitset of QapiSpecialFeature), because that's how special features get
passed around elsewhere.

6604e4757a qapi: Generalize command policy checking
The code to check command policy can see special feature flag
'deprecated' as command flag QCO_DEPRECATED.  I want to make feature
flag 'unstable' visible there as well, so I can add policy for it.

To let me make it visible, add member @special_features (a bitset of
QapiSpecialFeature) to QmpCommand, and adjust the generator to pass it
through qmp_register_command().  Then replace "QCO_DEPRECATED in
@flags" by QAPI_DEPRECATED in @special_features", and drop
QCO_DEPRECATED.

a130728554 qapi: Generalize struct member policy checking
The generated visitor functions call visit_deprecated_accept() and
visit_deprecated() when visiting a struct member with special feature
flag 'deprecated'.  This makes the feature flag visible to the actual
visitors.  I want to make feature flag 'unstable' visible there as
well, so I can add policy for it.

To let me make it visible, replace these functions by
visit_policy_reject() and visit_policy_skip(), which take the member's
special features as an argument.  Note that the new functions have the
opposite sense, i.e. the return value flips.

0e9030376e softfloat: add APIs to handle alternative sNaN propagation for fmax/fmin
For "fmax/fmin ft0, ft1, ft2" and if one of the inputs is sNaN,

  The original logic:
    Return NaN and set invalid flag if ft1 == sNaN || ft2 == sNan.

  The alternative path:
    Set invalid flag if ft1 == sNaN || ft2 == sNaN.
    Return NaN only if ft1 == NaN && ft2 == NaN.

The IEEE 754 spec allows both implementation and some architecture such
as riscv choose different defintions in two spec versions.
(riscv-spec-v2.2 use original version, riscv-spec-20191213 changes to
 alternative)

099f2df2e6 hw/acpi/aml-build: Add PPTT table
Add the Processor Properties Topology Table (PPTT) used to
describe CPU topology information to ACPI guests.

Note, a DT-boot Linux guest with a non-flat CPU topology will
see socket and core IDs being sequential integers starting
from zero, which is different from ACPI-boot Linux guest,
e.g. with -smp 4,sockets=2,cores=2,threads=1

a DT boot produces:

 cpu:  0 package_id:  0 core_id:  0
 cpu:  1 package_id:  0 core_id:  1
 cpu:  2 package_id:  1 core_id:  0
 cpu:  3 package_id:  1 core_id:  1

an ACPI boot produces:

 cpu:  0 package_id: 36 core_id:  0
 cpu:  1 package_id: 36 core_id:  1
 cpu:  2 package_id: 96 core_id:  2
 cpu:  3 package_id: 96 core_id:  3

This is due to several reasons:

 1) DT cpu nodes do not have an equivalent field to what the PPTT
    ACPI Processor ID must be, i.e. something equal to the MADT CPU
    UID or equal to the UID of an ACPI processor container. In both
    ACPI cases those are platform dependant IDs assigned by the
    vendor.

 2) While QEMU is the vendor for a guest, if the topology specifies
    SMT (> 1 thread), then, with ACPI, it is impossible to assign a
    core-id the same value as a package-id, thus it is not possible
    to have package-id=0 and core-id=0. This is because package and
    core containers must be in the same ACPI namespace and therefore
    must have unique UIDs.

 3) ACPI processor containers are not mandatorily required for PPTT
    tables to be used and, due to the limitations of which IDs are
    selected described above in (2), they are not helpful for QEMU,
    so we don't build them with this patch. In the absence of them,
    Linux assigns its own unique IDs. The maintainers have chosen not
    to use counters from zero, but rather ACPI table offsets, which
    explains why the numbers are so much larger than with DT.

 4) When there is no SMT (threads=1) the core IDs for ACPI boot guests
    match the logical CPU IDs, because these IDs must be equal to the
    MADT CPU UID (as no processor containers are present), and QEMU
    uses the logical CPU ID for these MADT IDs.

So in summary, with QEMU as the vendor for the guests, we simply
use sequential integers starting from zero for the non-leaf nodes
but with ID-valid flag unset, so that guest will ignore them and
use table offsets as unique container IDs. And we use logical CPU
IDs for the leaf nodes with the ID-valid flag set, which will be
consistent with MADT.

Currently the implementation of PPTT generation complies with ACPI
specification 5.2.29 (Revision 6.3). The 6.3 spec can be found at:

And we also tweak an error message of qemu_fdt_add_subnode().

31511b6fe0 hw/arm/virt: Only describe cpu topology since virt-6.2
On existing older machine types, without cpu topology described
in ACPI or DT, the guest will populate one by default. With the
topology described, it will read the information and set up its
topology as instructed, but that may not be the same as what was
getting used by default. It's possible that an user application
has a dependency on the default topology and if the default one
gets changed it will probably behave differently.

Based on above consideration we'd better only describe topology
information to the guest on 6.2 and later machine types.

Until now, int was used as the return type for all the ELF
loader related functions. The returned value is the sum of all loaded
program headers "MemSize" fields.

Because of the overflow check in elf_ops.h, trying to load an ELF bigger
than INT_MAX will fail. Switch to ssize_t to remove this limitation.

control virtqueue support for vhost-user backends. So this patch
implements the control virtqueue support for vhost-net. As datapath,
the control virtqueue is also required to be coupled with the
NetClientState. The vhost_net_start/stop() are tweaked to accept the
number of datapath queue pairs plus the the number of control
virtqueue for us to start and stop the vhost device.

4d191cfdc7 vhost-vdpa: classify one time request
Vhost-vdpa uses one device multiqueue queue (pairs) model. So we need
to classify the one time request (e.g SET_OWNER) and make sure those
request were only called once per device.

This is used for multiqueue support.

821d28b88f vhost-user-rng: Add vhost-user-rng implementation
Introduce a random number generator (RNG) backend that communicates
with a vhost-user server to retrieve entropy.  That way other VMM
that comply with the vhost user protocl can use the same vhost-user
daemon without having to write yet another RNG driver.

19d20e910a virtio-iommu: Drop base_name and change generic_name
Drop base_name and turn generic_name into
"virtio-iommu-pci". This is more in line with
other modern-only devices.

995b87dedc Revert "cpu: Move cpu_common_props to hw/core/cpu.c"
This reverts commit 1b36e4f5a5.

Despite a comment saying why cpu_common_props cannot be placed in
a file that is compiled once, it was moved anyway.  Revert that.

Since then, Property is not defined in hw/core/cpu.h, so it is now
easier to declare a function to install the properties rather than
the Property array itself.

bec4042bae block-backend: update blk_co_pwrite() and blk_co_pread() wrappers
Make bytes argument int64_t to be consistent with modern block-layer.
Callers should be OK with it as type becomes wider.

What is inside functions?

- Conversion from int64_t to size_t. Still, we
can't have a buffer larger than SIZE_MAX, therefore bytes should not be
larger than SIZE_MAX as well. Add an assertion.

- Passing to blk_co_pwritev() / blk_co_preadv() which already has
  int64_t bytes argument.

a93d81c84a block-backend: convert blk_aio_ functions to int64_t bytes paramter
1. Convert bytes in BlkAioEmAIOCB:
  aio->bytes is only passed to already int64_t interfaces, and set in
  blk_aio_prwv, which is updated here.

2. For all updated functions the parameter type becomes wider so callers
   are safe.

3. In blk_aio_prwv we only store bytes to BlkAioEmAIOCB, which is
   updated here.

4. Other updated functions are wrappers on blk_aio_prwv.

Note that blk_aio_preadv and blk_aio_pwritev become safer: before this
commit, it's theoretically possible to pass qiov with size exceeding
INT_MAX, which than converted to int argument of blk_aio_prwv. Now it's
converted to int64_t which is a lot better. Still add assertions.
