Richard Henderson 34e5e1dde5 plugins: Merge alloc_tcg_plugin_context into plugin_gen_tb_start
We don't need to allocate plugin context at startup,
we can wait until we actually use it.

Use the bytes that we record for the entire TB, rather than
a per-insn GByteArray.  Record the length of the insn in
plugin_gen_insn_end rather than infering from the length
of the array.

Thomas Huth 0d8caac904 Bump minimum glib version to v2.66
Now that we dropped support for CentOS 8 and Ubuntu 20.04, we can
look into bumping the glib version to a new minimum for further
clean-ups. According to repology.org, available versions are:

 CentOS Stream 9:       2.66.7
 Debian 11:             2.66.8
 Fedora 38:             2.74.1
 Freebsd:               2.78.4
 Homebrew:              2.80.0
 Openbsd:               2.78.4
 OpenSuse leap 15.5:    2.70.5
 pkgsrc_current:        2.78.4
 Ubuntu 22.04:          2.72.1

Thus it should be safe to bump the minimum glib version to 2.66 now.
Version 2.66 comes with new functions for URI parsing which will
allow further clean-ups in the following patches.

Daniel P. Berrangé 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.

Thomas Huth 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.

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.

Paolo Bonzini 47771d6756 hw/xtensa: require libfdt
All other boards require libfdt if it can be used (including for example
i386/x86_64), so change the "imply" to "select" and always allow -dtb
in qemu-system-xtensa.

Paolo Bonzini 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.

Paolo Bonzini 7a6f3343b6 meson: move libfdt together with other dependencies
Move the libfdt detection code together with other dependencies instead
of keeping it with subprojects.  This has the disadvantage of performing
the detection even if no target requires libfdt; but it has the advantage
that Kconfig will be able to observe the availability of the library.

The local APIC is a part of the CPU and has callbacks that are invoked
from multiple accelerators.

The IOAPIC on the other hand is optional, but ioapic_eoi_broadcast is
used by common x86 code to implement the IOAPIC's implicit EOI mode.
Add a stub in case the IOAPIC device is not included but the APIC is.

Paolo Bonzini 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.

Paolo Bonzini 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.

Prepare for moving the calls to xen_be_register() under the
control of xen_bus_init(), using the normal xen_backend_init()
method that is used by the "modern" backends.

This requires the xenstore global variable to be initialized,
which is done by xen_be_init().  To ensure that everything is
ready at the time the xen_backend_init() functions are called,
remove the xen_be_init() function from all the boards and
place it directly in xen_bus_init().

Paolo Bonzini 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.

Paolo Bonzini 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.
