I'm not documenting every single change in the codeconverter
script because most of that code will be deleted once we finish
the QOM code conversion.  This patch updates the script to the
latest version that was used to perform changes in the QOM code.

A comment in scripts/tracetool/__init__.py mentions that:

  We only want to allow standard C types or fixed sized
  integer types. We don't want QEMU specific types
  as we can't assume trace backends can resolve all the
  typedefs

dtrace USDT is fully supported since OS X 10.6. There are a few
peculiarities compared to other dtrace flavors.

1. It doesn't accept empty files.
2. It doesn't recognize bool type but accepts C99 _Bool.
3. It converts int8_t * in probe points to char * in
   header files and introduces [-Wpointer-sign] warning.

94dfc0f343 codeconverter: script for automating QOM code cleanups
This started as a simple script that scanned for regular
expressions, but became more and more complex when exceptions to
the rules were found.

I don't know if this should be maintained in the QEMU source tree
long term (maybe it can be reused for other code transformations
that Coccinelle can't handle).  In either case, this is included
as part of the patch series to document how exactly the automated
code transformations in the next patches were done.

8d60f37740 ninjatool: use constant names for stamp files
Numbering files according to rules causes confusion, because
CUSTOM_COMMAND3.stamp from a previous build might represent
completely different targets after Makefile.ninja is regenerated.
As a result, the new targets are not rebuilt and compilation
fails.

Use the targets to build a SHA1 hash; the chances for collision
are one in 2^24 even with a 12-character prefix of the hash.

40d9b74eaf mtest2make: unify tests that appear in multiple suites
Whenever a test appears in multiple suites, the rules generated
by mtest2make are currently running it twice.  Instead, after
this patch we generate a phony target for each test and we have
a generic "run-tests" target depend on all the tests that were
chosen on the command line.  Tests that appear in multiple suites
will be added to the prerequisites just once.

This has other advantages: it removes the handling of -k and

dcdc07a97c qapi: Make section headings start a new doc comment block
Our current QAPI doc-comment markup allows section headers (introduced
with a leading '=' or '==') anywhere in a free-form documentation
comment.  This works for Texinfo because the generator simply prints a
Texinfo section command at that point in the output stream.  For rST
generation, since we're assembling a tree of docutils nodes, this is
awkward because a new section implies starting a new section node at
the top level of the tree and generating text into there.

Make section headers start a new free-form documentation block, so the
future rST document generator doesn't have to look at every line in
free-form blocks and handle headings in odd places.

This change makes no difference to the generated Texinfo.

221db5daf6 qapi: enable use of g_autoptr with QAPI types
Currently QAPI generates a type and function for free'ing it:

  typedef struct QCryptoBlockCreateOptions QCryptoBlockCreateOptions;
  void qapi_free_QCryptoBlockCreateOptions(QCryptoBlockCreateOptions *obj);

This is used in the traditional manner:

  QCryptoBlockCreateOptions *opts = NULL;

  opts = g_new0(QCryptoBlockCreateOptions, 1);

  ....do stuff with opts...

  qapi_free_QCryptoBlockCreateOptions(opts);

Since bumping the min glib to 2.48, QEMU has incrementally adopted the
use of g_auto/g_autoptr. This allows the compiler to run a function to
free a variable when it goes out of scope, the benefit being the
compiler can guarantee it is freed in all possible code ptahs.

This benefit is applicable to QAPI types too, and given the seriously
long method names for some qapi_free_XXXX() functions, is much less
typing. This change thus makes the code generator emit:

 G_DEFINE_AUTOPTR_CLEANUP_FUNC(QCryptoBlockCreateOptions,
                              qapi_free_QCryptoBlockCreateOptions)

The above code example now becomes

  g_autoptr(QCryptoBlockCreateOptions) opts = NULL;

  opts = g_new0(QCryptoBlockCreateOptions, 1);

  ....do stuff with opts...

Note, if the local pointer needs to live beyond the scope holding the
variable, then g_steal_pointer can be used. This is useful to return the
pointer to the caller in the success codepath, while letting it be freed
in all error codepaths.

  return g_steal_pointer(&opts);

The crypto/block.h header needs updating to avoid symbol clash now that
the g_autoptr support is a standard QAPI feature.

a81df1b68b libqemuutil, qapi, trace: convert to meson
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.

139c1837db meson: rename included C source files to .c.inc
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.

243af0225a trace: switch position of headers to what Meson requires
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.

000822441e tracetool: carefully define SDT_USE_VARIADIC
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.

cbf97d5b79 qapi: Fix visit_type_STRUCT() not to fail for null object
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:
	#0 0x7f192d0c5d28 in __interceptor_calloc (/usr/lib/x86_64-linux-gnu/libasan.so.4+0xded28)
	#1 0x7f192cd21b10 in g_malloc0 (/usr/lib/x86_64-linux-gnu/libglib-2.0.so.0+0x51b10)

	#5 0x7f192cd42f29  (/usr/lib/x86_64-linux-gnu/libglib-2.0.so.0+0x72f29)

    SUMMARY: AddressSanitizer: 16 byte(s) leaked in 1 allocation(s).

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.

e3a23b4803 python/qmp.py: re-absorb MonitorResponseError
When I initially split this out, I considered this more of a machine
error than a QMP protocol error, but I think that's misguided.

Move this back to qmp.py and name it QMPResponseError. Convert
qmp.command() to use this exception type.

c02b2eac55 GitLab Gating CI: introduce pipeline-status contrib script
This script is intended to be used right after a push to a branch.

By default, it will look for the pipeline associated with the commit
that is the HEAD of the *local* staging branch.  It can be used as a
one time check, or with the `--wait` option to wait until the pipeline
completes.

If the pipeline is successful, then a merge of the staging branch into
the master branch should be the next step.

7aa12aa215 Remove the CONFIG_PRAGMA_DIAGNOSTIC_AVAILABLE switch
GCC supports "#pragma GCC diagnostic" since version 4.6, and
Clang seems to support it, too, since its early versions 3.x.
That means that our minimum required compiler versions all support
this pragma already and we can remove the test from configure and
all the related #ifdefs in the code.

86f13ef318 scripts: improve message when TAP based tests fail
If one of the qtests fails, the TAP driver prints out a message like:

  ERROR - too few tests run (expected 3, got 1)

which fails to tell you which test program failed. This is a critical
ommission when many tests are running in parallel as their output is
interleaved. The improved message is:

  ERROR endianness-test - too few tests run (expected 3, got 1)

27e08bab94 tracetool: work around ust <sys/sdt.h> include conflict
Both the dtrace and ust backends may include <sys/sdt.h> but LTTng
Userspace Tracer 2.11 and later requires SDT_USE_VARIADIC to be defined
before including the header file.

This is a classic problem with C header files included from different
parts of a program. If the same header is included twice within the same
compilation unit then the first inclusion determines the macro
environment.

Work around this by defining SDT_USE_VARIADIC in the dtrace backend too.
It doesn't hurt and fixes a missing STAP_PROBEV() compiler error when
the ust backend is enabled together with the dtrace backend.

ddd633e525 minikconf: explicitly set encoding to UTF-8
QEMU currently only has ASCII Kconfig files but Linux actually uses
UTF-8. Explicitly specify the encoding and that we're doing text file
I/O.

It's unclear whether or not QEMU will ever need Unicode in its Kconfig
files. If we start using the help text then it will become an issue
sooner or later. Make this change now for consistency with Linux
Kconfig.

fbb84f0741 run-coverity-scan: support --update-tools-only --docker
Just build the container when run-coverity-scan is invoked with
--update-tools-only --docker.  This requires moving the "docker build"
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
"FROM qemu:fedora" to make the Dockerfile small enough that it can be
included directly in the run-coverity-scan script.

7265905940 run-coverity-scan: use docker.py
Our trusted docker wrapper allows run-coverity-scan to run with both
docker and podman.

For the "run" phase this is transparent; for the "build" phase however
scripts are replaced with a bind mount (-v).  This is not an issue
because the secret option is meant for secrets stored globally in the
system and bind mounts are a valid substitute for secrets that are known
to whoever builds the container.

While it makes little sense for the end product to have a group
containing only a single pattern, avoiding this case within an

Because this is expected to be a transient condition, do not

08561fc128 decodetree: Move semantic propagation into classes
Create ExcMultiPattern to hold an set of non-overlapping patterns.
The body of build_tree, prop_format become member functions on this
class.  Add minimal member functions to Pattern and MultiPattern
to allow recusion through the tree.

Move the bulk of build_incmulti_pattern to prop_masks and prop_width
in MultiPattern, since we will need this for both kinds of containers.
Only perform prop_width for variablewidth.

Remove global patterns variable, and pass down container object into
parse_file from main.

No functional change in all of this.

7111a86e1b qapi: Assert non-input visitors see only valid alternate tags
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.

c978bd5226 qapi: Clean up visitor's recovery from input with invalid type
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().

  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.

a62d563796 scripts/kernel-doc: Add missing close-paren in c:function directives
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

b412378785 decodetree: Use Python3 floor division operator
This script started using Python2, where the 'classic' division
operator returns the floor result. In commit 3d004a371 we started
to use Python3, where the division operator returns the float
result ('true division').
To keep the same behavior, use the 'floor division' operator "//"
which returns the floor result.

781c67ca55 cpu: Use DeviceClass reset instead of a special CPUClass reset
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

84969111e6 scripts/cocci: Patch to let devices own their MemoryRegions
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)
      /exynos4210.dram0[0] (qemu:memory-region)
      /exynos4210.irom[0] (qemu:memory-region)
      /exynos4210.iram[0] (qemu:memory-region)
      /exynos4210.chipid[0] (qemu:memory-region)
      ...
      /device[26] (exynos4210.uart)
        /exynos4210.uart[0] (qemu:memory-region)
    /soc (exynos4210)
      ^
       \__ [*]

The irom/iram/chipid regions should go under 'soc' at [*].

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.)

19f7034773 Avoid address_space_rw() with a constant is_write argument
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

605ffebb2e scripts/qemu-trace-stap: Convert documentation to rST
The qemu-trace-stap documentation is currently in
scripts/qemu-trace-stap.texi in Texinfo format, which we
present to the user as:
 * a qemu-trace-stap manpage
 * but not (unusually for QEMU) part of the HTML docs

Convert the documentation to rST format that lives in
the docs/ subdirectory, and present it to the user as:
 * a qemu-trace-stap manpage
 * part of the interop/ Sphinx manual

There are minor formatting changes to suit Sphinx, but no
content changes.

b0cecc0d65 hxtool: Support SRST/ERST directives
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.

43d1455cf8 qapi: Fix code generation with Python 3.5
Recent commit 3e7fb5811b "qapi: Fix code generation for empty modules"
modules" switched QAPISchema.visit() from

    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.

Fix by making self._module_dict an OrderedDict rather than a dict.

3e7fb5811b qapi: Fix code generation for empty modules
When a sub-module doesn't contain any definitions, we don't generate
code for it, but we do generate the #include.

We generate code only for modules that get visited.
QAPISchema.visit() visits only modules that have definitions.  It can
visit modules multiple times.

Clean this up as follows.  Collect entities in their QAPISchemaModule.
Have QAPISchema.visit() call QAPISchemaModule.visit() for each module.
Have QAPISchemaModule.visit() call .visit_module() for itself, and
QAPISchemaEntity.visit() for each of its entities.  This way, we visit
each module exactly once.

a9f1dd7ee0 qapi: Proper intermediate representation for modules
Modules are represented only by their names so far.  Introduce class
QAPISchemaModule.  So far, it merely wraps the name.  The next patch
will put it to more interesting use.

Once again, arrays spice up the patch a bit.  For any other type,
@info points to the definition, which lets us map from @info to
module.  For arrays, there is no definition, and @info points to the
first use instead.  We have to use the element type's module instead,
which is only available after .check().

4cf4179441 docs: tweak kernel-doc for QEMU coding standards
Surprisingly, QEMU does have a pretty consistent doc comment style and
it is not very different from the Linux kernel's.  Of the documentation
"sigils", only "#" separates the QEMU doc comment style from Linux's,
and it has 200+ instances vs. 6 for the kernel's '&struct foo' (all in
accel/tcg/translate-all.c), so it's clear that the two standards are
different in this respect.  In addition, our structs are typedefed and
recognized by CamelCase names.

Adjust kernel-doc's parser for these two aspects of the QEMU coding
standards.  The patch has been valid, with hardly any change, for over
two years, so it should not be an issue to keep kernel-doc in sync with
the Linux copy.

e2c546358f docs: import Linux kernel-doc script and extension
Import Linux's kernel-doc script as of commit 15e2544ed38a1e, as well
as the Sphinx extension to call kernel-doc according to the arguments
and parameters given to a reStructuredText directive.

The kernel-doc extension accepts a filename, which is relative to
the QEMU source tree root.  The extension also notifies Sphinx about the
document dependency on the file, causing the document to be rebuilt when
the file has been changed.

b3cdff10e5 qapi: Lift features into QAPISchemaEntity
Commit 6a8c0b5102 "qapi: Add feature flags to struct types" added
features to QAPISchemaObjectType.  Commit a95daa5093 "qapi: Add
feature flags to commands in qapi" added them to QAPISchemaCommand,
duplicating the code.  Tolerable, but the duplication will only get
worse as we add features to more definitions.

To de-duplicate, lift features from QAPISchemaObjectType and
QAPISchemaCommand into QAPISchemaEntity.
