Translation logic may partially decode an instruction, then abort and
remove the instruction from the TB. This can happen for example when an
instruction spans two pages. In this case, plugins may get an incorrect
result when calling qemu_plugin_tb_n_insns to query for the number of
instructions in the TB. This patch updates plugin_gen_tb_end to set the
final instruction count.

All implementations of gdb_arch_name() returns dynamic duplicates of
static strings. It's also unlikely that there will be an implementation
of gdb_arch_name() that returns a truly dynamic value due to the nature
of the function returning a well-known identifiers. Qualify the value
gdb_arch_name() with const and make all of its implementations return

Always initialize the member in the subclasses for consistency.
This especially helps for AArch64; in a following change, the file
specified by gdb_core_xml_file is always looked up even if it's going to
be overwritten later. Looking up arm-core.xml results in an error as

However, when the ptr array gets reallocated, the other threads may have
a stale reference to the old buffer. This results in use-after-free.
Use GRWLock to properly fix this issue.

Currently query-dirty-rate uses QEMU_CLOCK_REALTIME as
the source for start-time field. This translates to
clock_gettime(CLOCK_MONOTONIC), i.e. number of seconds
since host boot. This is not very useful. The only
reasonable use case of start-time I can imagine is to
check whether previously completed measurements are
too old or not. But this makes sense only if start-time
is reported as host wall-clock time.
This patch replaces source of start-time from
QEMU_CLOCK_REALTIME to QEMU_CLOCK_HOST.

Default audio devices can now be created with "-audio". Tests for
soundcards were already using "-audiodev" if they want to specify a
particular backend, for the others remove the last remnants of
legacy audio configuration.

Make VNC use the default backend again if one is defined.
The recently introduced support for disabling the VNC audio
extension is still used, in case no default backend exists.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
It is now possible to specify the options for the default audio device
using -audio, so there is no need anymore to use a fake -audiodev option.
Remove the fall back to QTAILQ_FIRST(&audio_states), instead remember the
AudioState that was created from default_audiodevs and use that one.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
If "-audio BACKEND" is used without a model, the resulting backend
will be used whenever the audiodev property is not specified.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
Match what is done for other options, for example -monitor, and also
the behavior of QEMU 8.1 (see the "legacy_config" variable). Require
the user to specify a backend if one is specified on the command line.

Setting --bindir= to an absolute path that is shorter than the
prefix causes GCC to complain about array accesses out of bounds.
The code however is safe, so disable the warning and explain why
we are doing so.

"softmmu" is a deprecated moniker, do the easy change matching
the variable to the command line option.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
The softmmu/ directory contains files specific to system
emulation. Rename it as system/. Update meson rules, the
MAINTAINERS file and all the documentation and comments.

Finish the convertion started with commit de6cd7599b
("meson: Replace softmmu_ss -> system_ss"). If the
$target_type is 'system', then use the target_system_arch[]
source set :)
Mechanical change doing:
$ sed -i -e s/target_softmmu_arch/target_system_arch/g \
$(git grep -l target_softmmu_arch)
