qemu_opts_set is used to create default network backends and to
parse sugar options -kernel, -initrd, -append, -bios and -dtb.
These are very different uses:
I would *expect* a function named qemu_opts_set to set an option in a
merge-lists QemuOptsList, such as -kernel, and possibly to set an option
in a non-merge-lists QemuOptsList with non-NULL id, similar to -set.
However, it wouldn't *work* to use qemu_opts_set for the latter
because qemu_opts_set uses fail_if_exists==1. So, for non-merge-lists
QemuOptsList and non-NULL id, the semantics of qemu_opts_set (fail if the
(QemuOptsList, id) pair already exists) are debatable.
On the other hand, I would not expect qemu_opts_set to create a
non-merge-lists QemuOpts with a single option; which it does, though.
For this case of non-merge-lists QemuOptsList and NULL id, qemu_opts_set
hardly adds value over qemu_opts_parse. It does skip some parsing and
unescaping, but that's not needed when creating default network
backends.
So qemu_opts_set has warty behavior for non-merge-lists QemuOptsList
if id is non-NULL, and it's mostly pointless if id is NULL. My
solution to keeping the API as simple as possible is to limit
qemu_opts_set to merge-lists QemuOptsList. For them, it's useful (we
don't want comma-unescaping for -kernel) *and* has sane semantics.
Network backend creation is switched to qemu_opts_parse.
qemu_opts_set is now only used on merge-lists QemuOptsList... except
in the testcase, which is changed to use a merge-list QemuOptsList.
With this change we can also remove the id parameter. With the
parameter always NULL, we know that qemu_opts_create cannot fail
and can pass &error_abort to it.

Keep the machine initialization sequence free of miscellaneous command
line parsing actions.
The only difference is that preallocation will always be done with one
thread if -smp is not provided; previously it was using mc->default_cpus,
which is almost always 1 anyway.

Just like -incoming. Later we will add support for "-incoming defer
-preconfig", because there are cases (Xen, block layer) that want
to look at RUNSTATE_INMIGRATE. -loadvm will remain mutually exclusive
with preconfig; the plan is to just do loadvm in the monitor, since
the user is already going to interact with it for preconfiguration.

Some of the qtests use "-accel kvm -accel tcg" to run real guest code.
This causes some error messages when kvm is not available. We do not
really care about these messages since the fallback to tcg is expected
here. So let's silence them to avoid that they spoil the output of
the tests.
Unfortunately, we can not use the qtest_enabled() wrapper in this case,
since the qtest accelerator itself is not initialized. Thus we have to
test for the qtest_chrdev variable instead.

Over the years, most parts of exec.c that were not specific to softmmu
have been moved to accel/tcg; what's left is mostly the low-level part
of the memory API, which includes RAMBlock and AddressSpaceDispatch.
However exec.c also hosts 4-500 lines of code for the target specific
parts of the CPU QOM object, plus a few functions for user-mode
emulation that do not have a better place (they are not TCG-specific so
accel/tcg/user-exec.c is not a good place either).
Move these parts to a new file, so that exec.c can be moved to

This patch adds support of the reverse continue operation for gdbstub.
Reverse continue finds the last breakpoint that would happen in normal
execution from the beginning to the current moment.
Implementation of the reverse continue replays the execution twice:
to find the breakpoints that were hit and to seek to the last breakpoint.
Reverse continue loads the previous snapshot and tries to find the breakpoint
since that moment. If there are no such breakpoints, it proceeds to
the earlier snapshot, and so on. When no breakpoints or watchpoints were
hit at all, execution stops at the beginning of the replay log.

GDB remote protocol supports two reverse debugging commands:
reverse step and reverse continue.
This patch adds support of the first one to the gdbstub.
Reverse step is intended to step one instruction in the backwards
direction. This is not possible in regular execution.
But replayed execution is deterministic, therefore we can load one of
the prior snapshots and proceed to the desired step. It is equivalent
to stepping one instruction back.
There should be at least one snapshot preceding the debugged part of
the replay log.

refactoring of cpus.c continues with cpu timer state extraction.
cpu-timers: responsible for the softmmu cpu timers state,
including cpu clocks and ticks.
icount: counts the TCG instructions executed. As such it is specific to
the TCG accelerator. Therefore, it is built only under CONFIG_TCG.
One complication is due to qtest, which uses an icount field to warp time
as part of qtest (qtest_clock_warp).
In order to solve this problem, provide a separate counter for qtest.
This requires fixing assumptions scattered in the code that
qtest_enabled() implies icount_enabled(), checking each specific case.

clang's C11 atomic_fetch_*() functions only take a C11 atomic type
pointer argument. QEMU uses direct types (int, etc) and this causes a
compiler error when a QEMU code calls these functions in a source file
that also included <stdatomic.h> via a system header file:
$ CC=clang CXX=clang++ ./configure ... && make
../util/async.c:79:17: error: address argument to atomic operation must be a pointer to _Atomic type ('unsigned int *' invalid)
Avoid using atomic_*() names in QEMU's atomic.h since that namespace is
used by <stdatomic.h>. Prefix QEMU's APIs with 'q' so that atomic.h
and <stdatomic.h> can co-exist. I checked /usr/include on my machine and
searched GitHub for existing "qatomic_" users but there seem to be none.
This patch was generated using:
$ git grep -h -o '\<atomic\(64\)\?_[a-z0-9_]\+' include/qemu/atomic.h | \
sort -u >/tmp/changed_identifiers
$ for identifier in $(</tmp/changed_identifiers); do
sed -i "s%\<$identifier\>%q$identifier%g" \

Meson doesn't enjoy the same flexibility we have with Make in choosing
the include path. In particular the tracing headers are using
$(build_root)/$(<D).
In order to keep the include directives unchanged,
the simplest solution is to generate headers with patterns like
"trace/trace-audio.h" and place forwarding headers in the source tree
such that for example "audio/trace.h" includes "trace/trace-audio.h".
This patch is too ugly to be applied to the Makefiles now. It's only
a way to separate the changes to the tracing header files from the
Meson rewrite of the tracing logic.

This is a regression caused by commit d10e05f15d "tpm: Clean up error

continues to use error_report(), and we don't set an error when it

Similarly to commit 6fd5bef10b "qom: Make functions taking Error**
return bool, not void", let fw_cfg_add_from_generator() return a
boolean value, not void.
This allow to simplify parse_fw_cfg() and fixes the error handling
issue reported by Coverity (CID 1430396):
In parse_fw_cfg():
Variable assigned once to a constant guards dead code.
Local variable local_err is assigned only once, to a constant
value, making it effectively constant throughout its scope.
If this is not the intent, examine the logic to see if there
is a missing assignment that would make local_err not remain
constant.
It's the call of fw_cfg_add_from_generator():
Error *local_err = NULL;
fw_cfg_add_from_generator(fw_cfg, name, gen_id, errp);
if (local_err) {
error_propagate(errp, local_err);
return -1;
}
return 0;
If it fails, parse_fw_cfg() sets an error and returns 0, which is
wrong. Harmless, because the only caller passes &error_fatal.

The new -accel option does not accept colons in the parameters anymore
(since it does not convert the parameters to -machine accel=... parameters
anymore). Thus we can now remove the check for colons in -accel:
$ qemu-system-x86_64 -accel kvm:tcg
qemu-system-x86_64: -accel kvm:tcg: invalid accelerator kvm:tcg

move the vcpu throttling functionality into its own module.
This functionality is not specific to any accelerator,
and it is used currently by migration to slow down guests to try to
have migrations converge, and by the cocoa MacOS UI to throttle speed.
cpu-throttle contains the controls to adjust and inspect throttle
settings, start (set) and stop vcpu throttling, and the throttling
function itself that is run periodically on vcpus to make them take a nap.
Execution of the throttling function on all vcpus is triggered by a timer,
registered at module initialization.
No functionality change.

This is followup patch to the one submitted back in Oct, 19
https://lists.gnu.org/archive/html/qemu-devel/2019-10/msg02102.html
My mistake here, I took my eyes of the mailing list after I got the
initial thumbs up. This patch follows up on Markus comments in the
above link.
Purpose of this patch:
We want to print guest name for errors, warnings and info messages. This
was the first of two patches the second being MCE errors targeting a VM
with guest name prepended. But in a large fleet we see many other
errors that disable a VM or crash it. In a large fleet and centralized
logging having the guest name enables identify of owner and customer.
