The only functional difference between the GENERATED_HEADERS
and GENERATED_SOURCES variables is that 'Makefile' has a
dependancy on GENERATED_HEADERS, causing generated header files
to be created immediatey at the start of the build process.
There is no reason why this early creation should be restricted
to the .h files, and not include .c files too. Merge both of
the variables into a single GENERATED_FILES variable to make
it clear it is for any type of generated file.

Unfortunately some older versions of makeinfo don't correctly
handle the -D command line option and fail to set the variable.
This then causes them to complain

Work around this by doing as the autotools do, and writing
the information into a version.texi file which we then

By commit 67a1de0d, When we perform 'git pull && make && sudo make install',
In 'make' stage a qemu-version.h.tmp will be generated. If the content of
qemu-version.h.tmp and qemu-version.h aren't consistent, The qemu-version.h.tmp
will be renamed to qemu-version.h. Because of the target FORCE, The same action
will be do again in 'make install' stage.
In 'make install' stage, If there is no qemu-version.h.tmp exists and we run
'make install' with sudo, The owner and group of new qemu-version.h.tmp will be
privileged user/group. When we run 'make' next time, qemu-version.h.tmp can't
be overwritten because of permission issue.
This patch removed qemu-version.h.tmp after build to fix this issue.

have all the trouble with any protocol: validation, unix ancillary data,
shared memory, eventfd, logging, and on top of that you need to deal
with virtio queues, if possible efficiently.
qemu test has a nice vhost-user testing application vhost-user-bridge,
which implements most of vhost-user, and virtio.c which implements
virtqueues manipulation. Based on these two, I tried to make a simple

The quiet-command make rule currently takes two arguments:
the command and arguments to run, and a string to print if
the V flag is not set (ie we are not being verbose).
By convention, the string printed is of the form
" NAME some args". Unfortunately to get nicely lined up
output all the strings have to agree about what column the
arguments should start in, which means that if we add a
new quiet-command usage which wants a slightly longer CMD
name then we either put up with misalignment or change
every quiet-command string.
Split the quiet-mode string into two, the "NAME" and
the "same args" part, and use printf(1) to format the
string automatically. This means we only need to change
one place if we want to support a longer maximum name.
In particular, we can now print 7-character names lined
up properly (they are needed for the OSX "SETTOOL" invocation).
Change all the uses of quiet-command to the new syntax.
(Any which are missed or inadvertently reintroduced
via later merges will result in slightly misformatted
quiet output rather than disaster.)
A few places in the pc-bios/ makefiles are updated to use
"BUILD", "SIGN" and "STRIP" rather than "Building",
"Signing" and "Stripping" for consistency and to keep them
below 7 characters. Module .mo links now print "LD" rather
than the nonstandard "LD -r".

Extend the current module interface to allow for block drivers to be
loaded dynamically on request. The only block drivers that can be
converted into modules are the drivers that don't perform any init
operation except for registering themselves.
In addition, only the protocol drivers are being modularized, as they
are the only ones which see significant performance benefits. The format
drivers do not generally link to external libraries, so modularizing
them is of no benefit from a performance perspective.
All the necessary module information is located in a new structure found
in module_block.h
This spoils the purpose of 5505e8b76f (block/dmg: make it modular).
Before this patch, if module build is enabled, block-dmg.so is linked to
libbz2, whereas the main binary is not. In downstream, theoretically, it
means only the qemu-block-extra package depends on libbz2, while the
main QEMU package needn't to. With this patch, we (temporarily) change
the case so that the main QEMU depends on libbz2 again.

This adds a group of make targets to run docker tests, all are available
in source tree without running ./configure.
The usage is shown with "make docker".
Besides the fixed ones, dynamic targets for building each image and
running each test in each image are generated automatically by make,
scanning $(SRC_PATH)/tests/docker/ files with specific patterns.
Alternative to manually list particular targets (docker-TEST@IMAGE)
set, you can control which tests/images to run by filtering variables,
TESTS= and IMAGES=, which are expressed in Makefile pattern syntax,
"foo% %bar ...". For example:
$ make docker-test IMAGES="ubuntu fedora"
Unfortunately, it's impossible to propagate "-j $JOBS" into make in
containers, however since each combination is made a first class target
in the top Makefile, "make -j$N docker-test" still parallels the tests
coarsely.
Still, $J is made a magic variable to let all make invocations in
containers to use -j$J.
Instead of providing a live version of the source tree to the docker
container we snapshot it with git-archive. This ensures the tree is in a
pristine state for whatever operations the container is going to run on
them.
Uncommitted changes known to files known by the git index will be
included in the snapshot if there are any.

* on first build there is neither a .o nor a .d
* we create the .d as a side effect of creating the .o
* for rebuilds we know when we need to update the .o,
which also updates the .d
This system requires that you're never in a situation where there is
a .o file but no .d (because then we will never realise we need to
build the .d, and we will not have the dependency information about
when to rebuild the .o).
This is working fine for our object files, but we also try to use it
for $TARGET/config-devices.mak (where the dependency file is
in $TARGET-config-devices.mak.d). Unfortunately "make clean" doesn't
remove config-devices.mak, which means that it puts us in the
forbidden situation of "object file exists but not its .d file".
This in turn means that we will fail to notice when we need to rebuild:
mkdir build/depbug
(cd build/depbug && '../../configure')
make -C build/depbug -j8
make -C build/depbug clean
echo "CONFIG_CANARY = y" >> default-configs/arm-softmmu.mak
make -C build/depbug
grep CANARY build/depbug/aarch64-softmmu/config-devices.mak
The CANARY token should show up in config-devices.mak but does not.
Fix this bug by making "make clean" delete the config-devices.mak files.
config-all-devices.mak doesn't have the same problem since it has
no .d file, but delete it too, since it is created by "make" and
logically should be removed by "make clean".
(Note that it is important not to remove config-devices.mak until
after we have recursively run 'make clean' in the subdirectories.)

The windows socket functions look identical to the normal POSIX
sockets functions, but instead of setting errno, the caller needs
to call WSAGetLastError(). QEMU has tried to deal with this
incompatibility by defining a socket_error() method that callers
must use that abstracts the difference between WSAGetLastError()
and errno.
This approach is somewhat error prone though - many callers of
the sockets functions are just using errno directly because it
is easy to forget the need use a QEMU specific wrapper. It is
not always immediately obvious that a particular function will
in fact call into Windows sockets functions, so the dev may not
even realize they need to use socket_error().
This introduces an alternative approach to portability inspired
by the way GNULIB fixes portability problems. We use a macro to
redefine the original socket function names to refer to a QEMU
wrapper function. The wrapper function calls the original Win32
sockets method and then sets errno from the WSAGetLastError()
value.
Thus all code can simply call the normal POSIX sockets APIs are
have standard errno reporting on error, even on Windows. This
makes the socket_error() method obsolete.
We also bring closesocket & ioctlsocket into this approach. Even
though they are non-standard Win32 names, we can't wrap the normal
close/ioctl methods since there's no reliable way to distinguish
between a file descriptor and HANDLE in Win32.

This converts the NBD block driver client to use the QIOChannelSocket
class for initial connection setup. The NbdClientSession struct has
two pointers, one to the master QIOChannelSocket providing the raw
data channel, and one to a QIOChannel which is the current channel
used for I/O. Initially the two point to the same object, but when
TLS support is added, they will point to different objects.
The qemu-img & qemu-io tools now need to use MODULE_INIT_QOM to
ensure the QIOChannel object classes are registered. The qemu-nbd
tool already did this.
In this initial conversion though, all I/O is still actually done
using the raw POSIX sockets APIs.

Start the new generic I/O channel framework by defining a
QIOChannel abstract base class. This is designed to feel
similar to GLib's GIOChannel, but with the addition of
support for using iovecs, qemu error reporting, file
descriptor passing, coroutine integration and use of
the QOM framework for easier sub-classing.
The intention is that anywhere in QEMU that almost
anywhere that deals with sockets will use this new I/O
infrastructure, so that it becomes trivial to then layer
in support for TLS encryption. This will at least include
the VNC server, char device backend and migration code.

ab59e3e introduced a fix for `make install` on w32 that involved
filtering out qemu-ga from $TOOLS install recipe so that we could
append $(EXESUF) to it before attempting to install the binary
via install-prog function.
install-prog takes a list of binaries to install to a particular
directory. If the list is empty it breaks. We guard against this
by ensuring $TOOLS is not empty prior to calling.
However, ab59e3e introduces extra filtering after this check which
can still result on us attempting to call install-prog with an
empty list of binaries. In particular, this occurs if we
build with the --disable-tools configure option, which results
in qemu-ga being the only member of $TOOLS.
Fix this by doing a simple s/qemu-ga/qemu-ga$(EXESUF)/ pass through
$TOOLS instead of filtering out qemu-ga to handle it seperately.

fafcaf1 added a 'qemu-ga' install target on w32, which can be used
in place of the existing qemu-ga.exe target to also handle dealing
with other components such as DLLs for VSS/fsfreeze and generating
an MSI package if appropriate configure options are present.
As part of that, qemu-ga$(EXESUF) was removed from $TOOLS in favor
of this new qemu-ga target.
The install rule however relies on a direct mapping of the $TOOLS
entry to the actual resulting binary. In the case of w32, qemu-ga
is not identical to qemu-ga$(EXESUF), and the install recipe fails
to find the 'qemu-ga' binary.
Fix this by essentially remapping 'qemu-ga' back to 'qemu-ga.exe'
in the install recipe.
This raises the question of whether or not qemu-ga should continue
to live in TOOLS as opposed to its own special target, but as a
late fix for a regression in 2.5 this commit should be safer, since
we rely on qemu-ga's presence in $TOOLS in several places throughout
Makefile.

Currently POSIX builds rely on 'qemu-ga' target to do qga-only
distributable build. On w32, as with most standalone binary targets,
we rely on 'qemu-ga.exe' target.
Unlike with POSIX, qemu-ga for w32 has a number of related targets
such as VSS DLL and MSI package. We can do the full distributable
qga-only build on w32 with:
make qemu-ga.exe
or:
make msi
To make that work, we tie VSS dependencies onto qemu-ga.exe.
However, in reality the DLL isn't part of the binary, so we use a
filter to pull them out of the LINK recipe, which attempts to link
against prereqs for binary targets. Additionally, it could be argued
that VSS is a separate distributable, and shouldn't be implied by
qemu-ga.exe binary target.
To avoid this, we can tie the VSS dependencies only to the 'msi'
target, but that would make it impossible to do a qga-only build of
the w32 distributable without building the 'msi' package, which was
supported in the past.
An alternative approach is to add a new target to build the whole
distributable. w32 allows us to use the same build target we use
on POSIX, 'qemu-ga', since the current binary-only target on w32
is 'qemu-ga.exe'.
To further simplify the build, we also make 'qemu-ga' build the MSI
package if the appropriate ./configure options are set, making the
full qga-only build the same on both POSIX and w32: `make qemu-ga`

qapi/introspect.json defines the introspection schema. It's designed
for QMP introspection, but should do for similar uses, such as QGA.
The introspection schema does not reflect all the rules and
restrictions that apply to QAPI schemata. A valid QAPI schema has an
introspection value conforming to the introspection schema, but the
converse is not true.
Introspection lowers away a number of schema details, and makes
implicit things explicit:
* The built-in types are declared with their JSON type.
All integer types are mapped to 'int', because how many bits we use
internally is an implementation detail. It could be pressed into
external interface service as very approximate range information,
but that's a bad idea. If we need range information, we better do
it properly.
* Implicit type definitions are made explicit, and given
auto-generated names:
- Array types, named by appending "List" to the name of their
element type, like in generated C.
- The enumeration types implicitly defined by simple union types,
named by appending "Kind" to the name of their simple union type,
like in generated C.
- Types that don't occur in generated C. Their names start with ':'
so they don't clash with the user's names.
* All type references are by name.
* The struct and union types are generalized into an object type.
* Base types are flattened.
* Commands take a single argument and return a single result.
Dictionary argument or list result is an implicit type definition.
The empty object type is used when a command takes no arguments or
produces no results.
The argument is always of object type, but the introspection schema
doesn't reflect that.
The 'gen': false directive is omitted as implementation detail.
The 'success-response' directive is omitted as well for now, even
though it's not an implementation detail, because it's not used by
QMP.
* Events carry a single data value.
Implicit type definition and empty object type use, just like for
commands.
The value is of object type, but the introspection schema doesn't
reflect that.
* Types not used by commands or events are omitted.
Indirect use counts as use.
* Optional members have a default, which can only be null right now
Instead of a mandatory "optional" flag, we have an optional default.
No default means mandatory, default null means optional without
default value. Non-null is available for optional with default
(possible future extension).
* Clients should *not* look up types by name, because type names are
not ABI. Look up the command or event you're interested in, then
follow the references.
TODO Should we hide the type names to eliminate the temptation?
New generator scripts/qapi-introspect.py computes an introspection
value for its input, and generates a C variable holding it.
It can generate awfully long lines. Marked TODO.
A new test-qmp-input-visitor test case feeds its result for both
tests/qapi-schema/qapi-schema-test.json and qapi-schema.json to a
QmpInputVisitor to verify it actually conforms to the schema.
New QMP command query-qmp-schema takes its return value from that
variable. Its reply is some 85KiBytes for me right now.
If this turns out to be too much, we have a couple of options:
* We can use shorter names in the JSON. Not the QMP style.
* Optionally return the sub-schema for commands and events given as
arguments.
Right now qmp_query_schema() sends the string literal computed by
qmp-introspect.py. To compute sub-schema at run time, we'd have to
duplicate parts of qapi-introspect.py in C. Unattractive.
* Let clients cache the output of query-qmp-schema.
It changes only on QEMU upgrades, i.e. rarely. Provide a command
query-qmp-schema-hash. Clients can have a cache indexed by hash,
and re-query the schema only when they don't have it cached. Even
simpler: put the hash in the QMP greeting.

Future patches will be adding more crypto related APIs which
rely on QOM infrastructure. This creates a problem, because
QOM relies on library constructors to register objects. When
you have a file in a static .a library though which is only
referenced by a constructor the linker is dumb and will drop
that file when linking to the final executable :-( The only
workaround for this is to link the .a library to the executable
using the -Wl,--whole-archive flag, but this creates its own
set of problems because QEMU is relying on lazy linking for
libqemuutil.a. Using --whole-archive majorly increases the
size of final executables as they now contain a bunch of
object code they don't actually use.
The least bad option is to thus not include the crypto objects
in libqemuutil.la, and instead define a crypto-obj-y variable
that is referenced directly by all the executables that need
this code (tools + softmmu, but not qemu-ga). We avoid pulling
entire of crypto-obj-y into the userspace emulators as that
would force them to link to gnutls too, which is not required.

Now we can build qemu-ga MSI package with:

This patch enables parallel building of QEMU in MSYS+MinGW environment.
Currently an attempt to build QEMU in parallel fails on generation of
version.lo (and version.o too).
The cause of the failure is that when listing prerequisites "Makefile"
references "config-host.h" by absolute path in some rules and by relative
path in others. Make cannot figure out that these references points to the
same file which leads to the race: the generation of "version.*" which
requires "$(BUILD_DIR)/config-host.h" is launched in parallel with the
generation of "config-host.h" needed by other "Makefile" targets.
This patch removes "$(BUILD_DIR)/" prefix from corresponding prerequisite
of "version.*". There is no other prerequisites "$(BUILD_DIR)/config-host.h"
found.
Also note that not every version of MSYS is able to build QEMU in parallel,

Install the ./trace-events file into the data directory. This file
contains the list of trace events that were built into QEMU at
compile-time.
The file is a handy reference for the set of trace events that the QEMU
binary was built with. It is also needed by the simpletrace.py tool
that parses binary trace data either emitted from QEMU when built with
--enable-trace-backend=simple or by the SystemTap simpletrace script
that QEMU provides.

Generate header "trace/generated-tcg-tracers.h" with the necessary routines for
tracing events in guest code:
* trace_${event}_tcg
Convenience wrapper that calls the translation-time tracer
'trace_${event}_trans', and calls 'gen_helper_trace_${event}_exec to
generate the TCG code to later trace the event at execution time.

Generates header "trace/generated-helpers-wrappers.h" with definitions for TCG
helper wrappers.
These wrappers ('gen_helper_trace_${event}_exec_wrapper') transform mixed native
and TCG argument types to TCG types and call the actual TCG helpers
('gen_helper_trace_${event}_exec_proxy').
