ef6783d3f7 target: Simplify type checks for CpuModelInfo member @props
CpuModelInfo member @props is semantically a mapping from name to
value, and syntactically a JSON object on the wire.  This translates
to QDict in C.  Since the QAPI schema language lacks the means to
express 'object', we use 'any' instead.  This is QObject in C.
Commands taking a CpuModelInfo argument need to check the QObject is a
QDict.

For arm, riscv, and s390x, the code checks right before passing the
QObject to visit_start_struct().  visit_start_struct() then checks
again.

Delete the first check.

The error message for @props that are not an object changes slightly
to the the message we get for this kind of type error in other
contexts.  Minor improvement.

Additionally, error messages about members of @props now refer to
'props.prop-name' instead of just 'prop-name'.  Another minor
improvement.

Both changes are visible in tests/qtest/arm-cpu-features.c.

734e7b73df qga/commands-win32: Do not set matrix_lookup_t/win_10_0_t arrays size
ga_get_win_name() iterates over all elements in the arrays by
checking the 'version' field is non-NULL. Since the arrays are
guarded by a NULL terminating element, we don't need to specify
their size:

  static char *ga_get_win_name(...)
  {
      ...
      const ga_matrix_lookup_t *table = WIN_VERSION_MATRIX[tbl_idx];
      const ga_win_10_0_t *win_10_0_table = ...
      ...
      while (table->version != NULL) {
                    ^^^^^^^^^^^^^^^
              while (win_10_0_table->version != NULL) {
                                     ^^^^^^^^^^^^^^^

This will simplify maintenance when adding new entries to these
arrays.

Split WIN_VERSION_MATRIX into WIN_CLIENT_VERSION_MATRIX and
WIN_SERVER_VERSION_MATRIX because  multidimensional array must
have bounds for all dimensions except the first.

ef88e1e875 tests/unit/test-smp-parse: Test the full 7-levels topology hierarchy
Currently, -smp supports up to 7-levels topology hierarchy:
  -drawers/books/sockets/dies/clusters/cores/threads.

Though no machine supports all these 7 levels yet, these 7 levels have
the strict containment relationship and together form the generic CPU
topology representation of QEMU.

Also, note that the maxcpus is calculated by multiplying all 7 levels:

  maxcpus = drawers * books * sockets * dies * clusters *
            cores * threads.

To cover this code path, it is necessary to test the full topology case
(with all 7 levels). This also helps to avoid introducing new issues by
further expanding the CPU topology in the future.

54c4ea8f3a hw/core/machine-smp: Deprecate unsupported "parameter=1" SMP configurations
Currently, it was allowed for users to specify the unsupported
topology parameter as "1". For example, x86 PC machine doesn't
support drawer/book/cluster topology levels, but user could specify
"-smp drawers=1,books=1,clusters=1".

This is meaningless and confusing, so that the support for this kind of
configurations is marked deprecated since 9.0. And report warning
message for such case like:

qemu-system-x86_64: warning: Deprecated CPU topology (considered invalid):
                    Unsupported clusters parameter mustn't be specified as 1
qemu-system-x86_64: warning: Deprecated CPU topology (considered invalid):
                    Unsupported books parameter mustn't be specified as 1
qemu-system-x86_64: warning: Deprecated CPU topology (considered invalid):
                    Unsupported drawers parameter mustn't be specified as 1

Users have to ensure that all the topology members described with -smp
are supported by the target machine.

78abf93cc7 mac_newworld: change timebase frequency from 100MHz to 25MHz for mac99 machine
MacOS X uses multiple techniques for calibrating timers depending upon the detected
hardware. One of these calibration routines compares the change in the timebase
against the KeyLargo timer and uses this to recalculate the clock frequency,
timebase frequency and bus frequency if the calibration exceeds certain limits.
This recalibration occurs despite the correct values being passed via the device
tree, and is likely due to buggy firmware on some hardware.

The timebase frequency of 100MHz was set way back in 2005 by commit fa296b0fb4
("PIC fix - changed back TB frequency to 100 MHz") and with this value on a
mac99,via=pmu machine the OSX 10.2 timer calibration incorrectly calculates the
bus frequency as 400MHz instead of 100MHz. The most noticeable side-effect is
the UI appears sluggish and not very responsive for normal use.

Change the timebase frequency from 100MHz to 25MHz which matches that of a real
G4 AGP machine (the closest match to QEMU's mac99 machine) and allows OSX 10.2
to correctly detect all of the clock frequency, timebase frequency and bus
frequency.

Tested on various MacOS images from OS 9.2 through to OSX 10.4, along with Linux
and NetBSD and I was unable to find any regressions from this change.

f55cceac8c target/i386/sev: Fix missing ERRP_GUARD() for error_prepend()
As the comment in qapi/error, passing @errp to error_prepend() requires
ERRP_GUARD():

* = Why, when and how to use ERRP_GUARD() =
*
* Without ERRP_GUARD(), use of the @errp parameter is restricted:
...
* - It should not be passed to error_prepend(), error_vprepend() or
*   error_append_hint(), because that doesn't work with &error_fatal.
* ERRP_GUARD() lifts these restrictions.
*
* To use ERRP_GUARD(), add it right at the beginning of the function.
* @errp can then be used without worrying about the argument being
* NULL or &error_fatal.

ERRP_GUARD() could avoid the case when @errp is the pointer of
error_fatal, the user can't see this additional information, because
exit() happens in error_setg earlier than information is added [1].

The sev_inject_launch_secret() passes @errp to error_prepend(), and as
an APIs defined in target/i386/sev.h, it is necessary to protect its
@errp with ERRP_GUARD().

To avoid the issue like [1] said, add missing ERRP_GUARD() at the
beginning of this function.

The xen_netdev_connect() passes @errp to error_prepend(), and its @errp
parameter is from xen_device_frontend_changed().

Though its @errp points to @local_err of xen_device_frontend_changed(),
to follow the requirement of @errp, add missing ERRP_GUARD() at the
beginning of this function.
