This shows how to do some "computations" in meson.build using its array
and dictionary data structures, and also a basic usage of the sourceset
module for conditional compilation.
Notice the new "if have_system" part of util/meson.build, which fixes
a bug in the old build system was buggy: util/dbus.c was built even for
non-softmmu builds, but the dependency on -lgio was lost when the linking
was done through libqemuutil.a. Because all of its users required gio
otherwise, the bug was hidden. Meson instead propagates libqemuutil's
dependencies down to its users, and shows the problem.

Rules to execute tests are generated by a simple Python program
that integrates into the existing "make check" mechanism. This
provides familiarity for developers, and also allows piecewise
conversion of the testsuite Makefiles to meson.
The generated rules are based on QEMU's existing test harness
Makefile and TAP parser.

The Meson build system is integrated in the existing configure/make steps
by invoking Meson from the configure script and converting Meson's build.ninja
rules to an included Makefile.
build.ninja already provides tags/ctags/cscope rules, so they are removed.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
With Makefiles that have automatically generated dependencies, you
generated includes are set as dependencies of the Makefile, so that they
are built before everything else and they are available when first
building the .c files.
Alternatively you can use a fine-grained dependency, e.g.
target/arm/translate.o: target/arm/decode-neon-shared.inc.c
With Meson you have only one choice and it is a third option, namely
"build at the beginning of the corresponding target"; the way you
express it is to list the includes in the sources of that target.
The problem is that Meson decides if something is a source vs. a
generated include by looking at the extension: '.c', '.cc', '.m', '.C'
are sources, while everything else is considered an include---including
'.inc.c'.
Use '.c.inc' to avoid this, as it is consistent with our other convention
of using '.rst.inc' for included reStructuredText files. The editorconfig
file is adjusted.

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.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
Meson build scripts will only include qemu-fuzz-TARGET rules if configured
with --enable-fuzzing, and that takes care of adding -fsanitize=fuzzer.
Therefore we can just specify the configure option and stop modifying
the CFLAGS and CONFIG_FUZZ options in the "make" invocation.

The dtrace backend defines SDT_USE_VARIADIC as a workaround for a
conflict with a LTTng UST header file, which requires SDT_USE_VARIADIC
to be defined.
LTTng UST <lttng/tracepoint.h> breaks if included after generated dtrace
headers because SDT_USE_VARIADIC will already be defined:
#ifdef LTTNG_UST_HAVE_SDT_INTEGRATION
#define SDT_USE_VARIADIC <-- error, it's already defined
#include <sys/sdt.h>
Be more careful when defining SDT_USE_VARIADIC. This fixes the build
when both the dtrace and ust tracers are enabled at the same time.

To make deallocating partially constructed objects work, the
visit_type_STRUCT() need to succeed without doing anything when passed
a null object.
Commit cdd2b228b9 "qapi: Smooth visitor error checking in generated
code" broke that. To reproduce, run tests/test-qobject-input-visitor
with AddressSanitizer:
==4353==ERROR: LeakSanitizer: detected memory leaks
Direct leak of 16 byte(s) in 1 object(s) allocated from:

Test case /visitor/input/fail/struct-in-list feeds a list with a bad
element to the QObject input visitor. Visiting that element duly
fails, and aborts the visit with the list only partially constructed:
the faulty object is null. Cleaning up the partially constructed list
visits that null object, fails, and aborts the visit before the list
node gets freed.
Fix the the generated visit_type_STRUCT() to succeed for null objects.

This is a classic problem with C header files included from different

Work around this by defining SDT_USE_VARIADIC in the dtrace backend too.

Just build the container when run-coverity-scan is invoked with

logic into the update_coverity_tools function.
The only snag is that --update-tools-only --docker requires access to
the dockerfile. For now just report an error for --src-tarball, and
"docker build" will fail if not in a source tree. Another possibility
could be to host our container images on a public registry, and use

there's just one caller that passes null instead of an empty QDict.
Adjust that caller, and simplify gen_marshal().

An alternate type's visit_type_FOO() fails when it runs into an
invalid ->type.
This is appropriate with an input visitor: visit_start_alternate()
sets ->type according to the input, and bad input can lead to bad
->type.
It should never happen with an output, clone or dealloc visitor: if it
did, the alternate being output, cloned or deallocated would be messed
up beyond repair. Assert that.

An alternate type's visit_type_FOO() fails when it runs into an
invalid ->type. If it's an input visit, we then need to free the the
object we got from visit_start_alternate(). We do that with
qapi_free_FOO(), which uses the dealloc visitor.
Trouble is that object is in a bad state: its ->type is invalid. So
the dealloc visitor will run into the same error again, and the error
recovery skips deallocating the alternate's (invalid) alternative.
Works, because qapi_free_FOO() ignores the error.
Avoid it instead: free the messed up object with by g_free().

The kernel-doc Sphinx plugin and associated script currently emit
'c:type' directives for "struct foo" documentation.
Sphinx 3.0 warns about this:
/home/petmay01/linaro/qemu-from-laptop/qemu/docs/../include/exec/memory.h:3: WARNING: Type must be either just a name or a typedef-like declaration.
If just a name:
Error in declarator or parameters
Invalid C declaration: Expected identifier in nested name, got keyword: struct [error at 6]
struct MemoryListener
------^
If typedef-like declaration:
Error in declarator or parameters
Invalid C declaration: Expected identifier in nested name. [error at 21]
struct MemoryListener
---------------------^
because it wants us to use the new-in-3.0 'c:struct' instead.
Plumb the Sphinx version through to the kernel-doc script
and use it to select 'c:struct' for newer versions than 3.0.

When kernel-doc generates a 'c:function' directive for a function
one of whose arguments is a function pointer, it fails to print
the close-paren after the argument list of the function pointer
argument, for instance in the memory API documentation:
.. c:function:: void memory_region_init_resizeable_ram (MemoryRegion * mr, struct Object * owner, const char * name, uint64_t size, uint64_t max_size, void (*resized) (const char*, uint64_t length, void *host, Error ** errp)
which should have a ')' after the 'void *host' which is the
last argument to 'resized'.
Older versions of Sphinx don't try to parse the argumnet
to c:function, but Sphinx 3.0 does do this and will complain:
/home/petmay01/linaro/qemu-from-laptop/qemu/docs/../include/exec/memory.h:834: WARNING: Error in declarator or parameters
Invalid C declaration: Expecting "," or ")" in parameters, got "EOF". [error at 208]

The CPUClass has a 'reset' method. This is a legacy from when
TYPE_CPU used not to inherit from TYPE_DEVICE. We don't need it any
more, as we can simply use the TYPE_DEVICE reset. The 'cpu_reset()'
function is kept as the API which most places use to reset a CPU; it
is now a wrapper which calls device_cold_reset() and then the
tracepoint function.
This change should not cause CPU objects to be reset more often
than they are at the moment, because:
* nobody is directly calling device_cold_reset() or
qdev_reset_all() on CPU objects
* no CPU object is on a qbus, so they will not be reset either
by somebody calling qbus_reset_all()/bus_cold_reset(), or
by the main "reset sysbus and everything in the qbus tree"
reset that most devices are reset by
Note that this does not change the need for each machine or whatever
to use qemu_register_reset() to arrange to call cpu_reset() -- that
is necessary because CPU objects are not on any qbus, so they don't
get reset when the qbus tree rooted at the sysbus bus is reset, and
this isn't being changed here.
All the changes to the files under target/ were made using the
included Coccinelle script, except:
(1) the deletion of the now-inaccurate and not terribly useful
"CPUClass::reset" comments was done with a perl one-liner afterwards:
perl -n -i -e '/ CPUClass::reset/ or print' target/*/*.c
(2) this bit of the s390 change was done by hand, because the
Coccinelle script is not sophisticated enough to handle the
parent_reset call being inside another function:
| @@ -96,8 +96,9 @@ static void s390_cpu_reset(CPUState *s, cpu_reset_type type)

When a device creates a MemoryRegion without setting its ownership,
the MemoryRegion is added to the machine "/unattached" container in
the QOM tree.
Example with the Samsung SMDKC210 board:
$ arm-softmmu/qemu-system-arm -M smdkc210 -S -monitor stdio
(qemu) info qom-tree
/machine (smdkc210-machine)
/unattached (container)
/io[0] (qemu:memory-region)

...
/device[26] (exynos4210.uart)
/exynos4210.uart[0] (qemu:memory-region)
/soc (exynos4210)

This adds and parses the --monitor option, so that a QMP monitor can be
used in the storage daemon. The monitor offers commands defined in the
QAPI schema at storage-daemon/qapi/qapi-schema.json.
The --monitor options currently allows to create multiple monitors with
the same ID. This part of the interface is considered unstable. We will
reject such configurations as soon as we have a design for the monitor
subsystem to perform these checks. (In the system emulator, we depend on
QemuOpts rejecting duplicate IDs.)

The address_space_rw() function allows either reads or writes
depending on the is_write argument passed to it; this is useful
when the direction of the access is determined programmatically
(as for instance when handling the KVM_EXIT_MMIO exit reason).
Under the hood it just calls either address_space_write() or
address_space_read_full().
We also use it a lot with a constant is_write argument, though,
which has two issues:
* when reading "address_space_rw(..., 1)" this is less
immediately clear to the reader as being a write than
"address_space_write(...)"
* calling address_space_rw() bypasses the optimization
in address_space_read() that fast-paths reads of a
fixed length

We want to add support for including rST document fragments
in our .hx files, in the same way we currently have texinfo
fragments. These will be delimited by SRST and ERST directives,
in the same way the texinfo is delimited by STEXI/ETEXI.
The rST fragments will not be extracted by the hxtool
script, but by a different mechanism, so all we need to
do in hxtool is have it ignore all the text inside a
SRST/ERST section, with suitable error-checking for
mismatched rST-vs-texi fragment delimiters.
The resulting effective state machine has only three states:
* flag = 0, rstflag = 0 : reading section for C output
* flag = 1, rstflag = 0 : reading texi fragment
* flag = 0, rstflag = 1 : reading rST fragment
and flag = 1, rstflag = 1 is not possible. Using two
variables makes the parallel between the rST handling and
the texi handling clearer; in any case all this code will
be deleted once we've converted entirely to rST.

for entity in self._entity_list:
effectively to
for mod in self._module_dict.values():
for entity in mod._entity_list:
Visits in the same order as long as .values() is in insertion order.
That's the case only for Python 3.6 and later. Before, it's in some
arbitrary order, which results in broken generated code.

@info points to the definition, which lets us map from @info to
