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:

b863f0b758 device_tree: Add qemu_fdt_add_path
qemu_fdt_add_path() works like qemu_fdt_add_subnode(), except it
also adds all missing subnodes from the given path. We'll use it
in a coming patch where we will add cpu-map to the device tree.

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.

8975eb891f hw/elf_ops.h: switch to ssize_t for elf loader return type
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.

05ba3f63d1 vhost-net: control virtqueue support
We assume there's no cvq in the past, this is not true when we need
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.

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

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.

f3558b1b76 qdev: Base object creation on QDict rather than QemuOpts
QDicts are both what QMP natively uses and what the keyval parser
produces. Going through QemuOpts isn't useful for either one, so switch
the main device creation function to QDicts. By sharing more code with
the -object/object-add code path, we can even reduce the code size a
bit.

This commit doesn't remove the detour through QemuOpts from any code
path yet, but it allows the following commits to do so.

259a10dbcb virtio-net: Store failover primary opts pointer locally
Instead of accessing the global QemuOptsList, which really belong to the
command line parser and shouldn't be accessed from devices, store a
pointer to the QemuOpts in a new VirtIONet field.

This is not the final state, but just an intermediate step to get rid of
QemuOpts in devices. It will later be replaced with an options QDict.

Before this patch, two "primary" devices could be hidden for the same
standby device, but only one of them would actually be enabled and the
other one would be kept hidden forever, so this doesn't make sense.
After this patch, configuring a second primary device is an error.

7d61808206 qdev: Add Error parameter to hide_device() callbacks
hide_device() is used for virtio-net failover, where the standby virtio
device delays creation of the primary device. It only makes sense to
have a single primary device for each standby device. Adding a second
one should result in an error instead of hiding it and never using it
afterwards.

Prepare for this by adding an Error parameter to the hide_device()
callback where virtio-net is informed about adding a primary device.

4a1d937796 softmmu/qdev-monitor: add error handling in qdev_set_id
qdev_set_id() is mostly used when the user adds a device (using
-device cli option or device_add qmp command). This commit adds
an error parameter to handle the case where the given id is
already taken.

Also document the function and add a return value in order to
be able to capture success/failure: the function now returns the
id in case of success, or NULL in case of failure.

The commit modifies the 2 calling places (qdev-monitor and
xen-legacy-backend) to add the error object parameter.

Note that the id is, right now, guaranteed to be unique because
all ids came from the "device" QemuOptsList where the id is used
as key. This addition is a preparation for a future commit which
will relax the uniqueness.

e287bf7bb1 net: Introduce NetClientInfo.check_peer_type()
Some network backends (vhost-user and vhost-vdpa) work only with
specific devices. At startup, they second guess what the command line
option handling will do and error out if they think a non-virtio device
will attach to them.

This second guessing is not only ugly, it can lead to wrong error
messages ('-device floppy,netdev=foo' should complain about an unknown
property, not about the wrong kind of network device being attached) and
completely ignores hotplugging.

Add a callback where backends can check compatibility with a device when
it actually tries to attach, even on hotplug.

These functions are much closer to the softmmu helper
functions, in that they take the complete MemOpIdx,
and from that they may enforce required alignment.

The previous cpu_ldst.h functions did not have alignment info,
and so did not enforce it.  Retain this by adding MO_UNALN to
the MemOp that we create in calling the new functions.

Note that we are not yet enforcing alignment for user-only,
but we now have the information with which to do so.

453d50ce75 accel/tcg: re-factor plugin_inject_cb so we can assert insn_idx is valid
Coverity doesn't know enough about how we have arranged our plugin TCG
ops to know we will always have incremented insn_idx before injecting
the callback. Let us assert it for the benefit of Coverity and protect
ourselves from accidentally breaking the assumption and triggering
harder to grok errors deeper in the code if we attempt a negative
indexed array lookup.

However to get to this point we re-factor the code and remove the
second hand instruction boundary detection in favour of scanning the
full set of ops and using the existing INDEX_op_insn_start to cleanly
detect when the instruction has started. As we no longer need the
plugin specific list of ops we delete that.

My initial benchmarks shows no discernible impact of dropping the
plugin specific ops list.

87bd33e8b0 hw: aspeed_gpio: Fix GPIO array indexing
The gpio array is declared as a dense array:

  qemu_irq gpios[ASPEED_GPIO_NR_PINS];

(AST2500 has 228, AST2400 has 216, AST2600 has 208)

However, this array is used like a matrix of GPIO sets
(e.g. gpio[NR_SETS][NR_PINS_PER_SET] = gpio[8][32])

  size_t offset = set * GPIOS_PER_SET + gpio;
  qemu_set_irq(s->gpios[offset], !!(new & mask));

This can result in an out-of-bounds access to "s->gpios" because the
gpio sets do _not_ have the same length. Some of the groups (e.g.
GPIOAB) only have 4 pins. 228 != 8 * 32 == 256.

To fix this, I converted the gpio array from dense to sparse, to that
match both the hardware layout and this existing indexing code.
