b563959b90 gitlab: use 'setarch -R' to workaround tsan bug
The TSAN job started failing when gitlab rolled out their latest
release. The root cause is a change in the Google COS version used
on shared runners. This brings a kernel running with

 vm.mmap_rnd_bits = 31

which is incompatible with TSAN in LLVM < 18, which only supports
upto '28'. LLVM 18 can support upto '30', and failing that will
re-exec itself to turn off VA randomization.

Our LLVM is too old for now, but we can run with 'setarch -R make ..'
to turn off VA randomization ourselves.

c53f7a1078 gitlab: use $MAKE instead of 'make'
The lcitool generated containers have '$MAKE' set to the path
of the right 'make' binary. Using the env variable makes it

371d60dfdb configure: Fix error message when C compiler is not working
If you try to run the configure script on a system without a working
C compiler, you get a very misleading error message:

 ERROR: Unrecognized host OS (uname -s reports 'Linux')

Some people already opened bug tickets because of this problem:

 https://gitlab.com/qemu-project/qemu/-/issues/2057
 https://gitlab.com/qemu-project/qemu/-/issues/2288

We should rather tell the user that we were not able to use the C
compiler instead, otherwise they will have a hard time to figure
out what was going wrong.

While we're at it, let's also suppress the "unrecognized host CPU"
message in this case since it is rather misleading than helpful.

9b089d254a configs: disable emulators that require it if libfdt is not found
Since boards can express their dependency on libfdt and
system/device_tree.c, only leave TARGET_NEED_FDT if the target has a
hard dependency.

Those emulators will be skipped if libfdt is disabled, or if it
is "auto" and not found and --disable-download is passed; unless
the target is mentioned explicitly in --target-list, in which case
the build will fail.

d641ec30be kconfig: express dependency of individual boards on libfdt
Now that boards are enabled by default and the "CONFIG_FOO=y"
entries are gone from configs/devices/, there cannot be any more
a conflicts between the default contents of configs/devices/
and a failed "depends on" clause.

With this change, each individual board or target can express
whether it needs FDT.  It can then include the common code in the
build via "select DEVICE_TREE", which will also as tell meson to link
with libfdt.

This allows building non-microvm x86 emulators without having
libfdt available.

Move the libfdt detection code together with other dependencies instead

that Kconfig will be able to observe the availability of the library.

The IOAPIC on the other hand is optional, but ioapic_eoi_broadcast is

d0be0ac2c3 hw/i386: move rtc-reset-reinjection command out of hw/rtc
The rtc-reset-reinjection QMP command is specific to x86, other boards do not
have the ACK tracking functionality that is needed for RTC interrupt
reinjection.  Therefore the QMP command is only included in x86, but
qmp_rtc_reset_reinjection() is implemented by hw/rtc/mc146818rtc.c
and requires tracking of all created RTC devices.  Move the implementation
to hw/i386, so that 1) it is available even if no RTC device exist
2) the only RTC that exists is easily found in x86ms->rtc.

88f5ed7017 xen: register legacy backends via xen_backend_init
It is okay to register legacy backends in the middle of xen_bus_init().
All that the registration does is record the existence of the backend
in xenstore.

This makes it possible to remove them from the build without introducing
undefined symbols in xen_be_init().  It also removes the need for the
backend_register callback, whose only purpose is to avoid registering
nonfunctional backends.

fa5365e8b6 tests/qtest: s390x: fix operation in a build without any boards or devices
Do the bare minimum to ensure that at least a vanilla
--without-default-devices build works for all targets except i386,
x86_64 and ppc64.  In particular this fixes s390x-softmmu; i386 and
x86_64 have about a dozen failing tests that do not pass -M and therefore
require a default machine type; ppc64 has the same issue, though only
with numa-test.

If we can for now ignore the cases where boards and devices are picked
by hand, drive_del-test however can be fixed easily; almost all tests
check for the virtio-blk or virtio-scsi device that they use, and are
already skipped.  Only one didn't get the memo; plus another one does
not need a machine at all and can be run with -M none.

23b1f53c2c configure: quote -D options that are passed through to meson
Ensure that they go through unmodified, instead of removing one layer
of quoting.

-D is a pretty specialized option and most options that can have spaces
do not need it (for example, c_args is covered by --extra-cflags).
Therefore it's unlikely that this causes actual trouble.  However,
a somewhat realistic failure case would be with -Dpkg_config_path
and a pkg-config directory that contains spaces.

95e0fb0afa qemu-options: Deprecate "-runas" and introduce "-run-with user=..." instead
The old "-runas" option has the disadvantage that it is not visible
in the QAPI schema, so it is not available via the normal introspection
mechanisms. We've recently introduced the "-run-with" option for exactly
this purpose, which is meant to handle the options that affect the
runtime behavior. Thus let's introduce a "user=..." parameter here now
and deprecate the old "-runas" option.

Retain a list of deprecated features disjoint from any particular
CPU model. A query-cpu-model-expansion reply will now provide a list of
properties (i.e. features) that are flagged as deprecated. Example:

    {
      "return": {
        "model": {
          "name": "z14.2-base",
          "deprecated-props": [

          }

It is recommended that s390 guests operate with these features

5872966db7 target/loongarch: Put cpucfg operation before CSR register
On Loongarch, cpucfg is register for cpu feature, some other registers
depend on cpucfg feature such as perf CSR registers. Here put cpucfg
read/write operations before CSR register, so that KVM knows how many
perf CSR registers are valid from pre-set cpucfg feature information.

In structure CPUArchState some struct elements are only used in TCG
mode, and it is not used in KVM mode. Macro CONFIG_TCG is added to
make it simpiler in KVM mode, also there is the same modification
in c code when these structure elements are used.

When VM runs in KVM mode, TLB entries are not used and do not need
migrate. It is only useful when it runs in TCG mode.

f532cf0131 hw/loongarch: Refine default numa id calculation
With numa_test test case, there is subcase named test_def_cpu_split(),
there are 8 sockets and 2 numa nodes. Here is command line:
"-machine smp.cpus=8,smp.sockets=8 -numa node,memdev=ram -numa node"

The required result is:
  node 0 cpus: 0 2 4 6
  node 1 cpus: 1 3 5 7
Test case numa_test fails on LoongArch, since the actual result is:
  node 0 cpus: 0 1 2 3
  node 1 cpus: 4 5 6 7

It will be better if all the cpus in one socket share the same numa
node. Here socket id is used to calculate numa id in function
virt_get_default_cpu_node_id().

8b4d80bb53 misc: Use QEMU header path relative to include/ directory
QEMU headers are relative to the include/ directory,
not to the project root directory. Remove "include/".

91d0b151de hw/intc/loongson_ipi: Implement IOCSR address space for MIPS
Implement IOCSR address space get functions for MIPS/Loongson CPUs.

For MIPS/Loongson without IOCSR (i.e. Loongson-3A1000), get_cpu_iocsr_as
will return as null, and send_ipi_data will fail with MEMTX_DECODE_ERROR,
which matches expected behavior on hardware.
