Memory map table for fwcfg is used for UEFI BIOS, UEFI BIOS uses the first
entry from fwcfg memory map as the first memory HOB, the second memory HOB
will be used if the first memory HOB is used up.
Memory map table for fwcfg does not care about numa node, however in
generic the first memory HOB is part of numa node0, so that runtime
memory of UEFI which is allocated from the first memory HOB is located
at numa node0.

GDB commit a207f6b3a38 ('Rewrite "python" command exception handling')
changed how exit() called from Python scripts loaded by GDB behave,
turning it into an exception instead of a generic error code that is
returned. This change caused several QEMU tests to crash with the
following exception:
Python Exception <class 'SystemExit'>: 0
Error occurred in Python: 0
This happens because in tests/guest-debug/test_gdbstub.py exit is
called after the tests have completed.
This commit fixes it by politely asking GDB to exit via gdb.execute,
passing the proper fail_count to be reported to 'make', instead of
abruptly calling exit() from the Python script.

This effectively reverts
commit 54c4ea8f3a
Author: Zhao Liu <zhao1.liu@intel.com>
Date: Sat Mar 9 00:01:37 2024 +0800
hw/core/machine-smp: Deprecate unsupported "parameter=1" SMP configurations
but is not done as a 'git revert' since the part of the changes to the
file hw/core/machine-smp.c which add 'has_XXX' checks remain desirable.
Furthermore, we have to tweak the subsequently added unit test to
account for differing warning message.
The rationale for the original deprecation was:
"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."
There are varying POVs on the topic of 'unsupported' topology levels.
It is common to say that on a system without hyperthreading, that there
is always 1 thread. Likewise when new CPUs introduced a concept of
multiple "dies', it was reasonable to say that all historical CPUs
before that implicitly had 1 'die'. Likewise for the more recently
introduced 'modules' and 'clusters' parameter'. From this POV, it is
valid to set 'parameter=1' on the -smp command line for any machine,
only a value > 1 is strictly an error condition.
It doesn't cause any functional difficulty for QEMU, because internally
the QEMU code is itself assuming that all "unsupported" parameters
implicitly have a value of '1'.
At the libvirt level, we've allowed applications to set 'parameter=1'
when configuring a guest, and pass that through to QEMU.
Deprecating this creates extra difficulty for because there's no info
exposed from QEMU about which machine types "support" which parameters.
Thus, libvirt can't know whether it is valid to pass 'parameter=1' for
a given machine type, or whether it will trigger deprecation messages.
Since there's no apparent functional benefit to deleting this deprecated
behaviour from QEMU, and it creates problems for consumers of QEMU,
remove this deprecation.

Local pointer info is freed before return from
iommufd_cdev_get_info_iova_range().
Use 'g_autofree' to avoid the g_free() calls.

Local pointer name is allocated before vfio_attach_device() call
and freed after the call.
Same for tmp when calling realpath().
Use 'g_autofree' to avoid the g_free() calls.

Move trace_vfio_migration_set_state() to the top of the function, add
recover_state to it, and add a new trace event to
vfio_migration_set_device_state().
This improves tracing of device state changes as state changes are now
also logged when vfio_migration_set_state() fails (covering recover
state and device reset transitions) and in no-op state transitions to
the same state.
