2015-12-18io: add abstract QIOChannel classesDaniel P. Berrange
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. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
2015-11-25makefile: fix qemu-ga make install for --disable-toolsMichael Roth
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.

2015-11-17makefile: fix w32 install target for qemu-gaMichael Roth
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.

2015-10-19build: qemu-ga: add 'qemu-ga' build target for w32Michael Roth
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` Cc: Paolo Bonzini <pbonzini@redhat.com> Cc: Marc-André Lureau <marcandre.lureau@redhat.com> Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>
2015-09-25Makefile: fix build when VPATH is outside GIT treeDaniel P. Berrange
Steve Ellcey / Leon Alrae reported that QEMU fails to build when the VPATH directory is outside of the GIT tree, and the system emulators & tools build is disabled. eg cd .. mkdir build cd build ../qemu/configure --disable-system --disable-tools make (...) make[1]: *** No rule to make target `../qom/object.o', needed by `qemu-aarch64'. Stop. make: *** [subdir-aarch64-linux-user] Error 2 The problem is due to the fact that some sub directory deps were listed against SOFTMMU_SUBDIR_RULES instead of SUBDIR_RULES, so were only processed for system emulators, not user emalutors.

2015-09-21qapi: New QMP command query-qmp-schema for QMP introspectionMarkus Armbruster
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. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>

2015-09-15qom: allow QOM to be linked into tools binariesDaniel P. Berrange
The qom objects are currently added to common-obj-y which is only linked into the system emulators. The later crypto patches will depend on QOM infrastructure and will also be used from tools binaries. Thus the QOM objects are moved into a new qom-obj-y variable which can be referenced when linking tools, system emulators and tests. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
2015-09-15crypto: move crypto objects out of libqemuutil.laDaniel P. Berrange
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. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>

2015-09-01build: qemu-ga: fix VSS dependenciesMichael Roth
Currently VSS dll/tlb files for use in w32 builds are only built as a result of having been added to the general 'tools' target alongside qemu-ga. This is fine for default make target, but if we build qemu-ga directly via `make qemu-ga.exe`, the VSS files are not created. Fix this by moving the VSS dependencies to qemu-ga.exe directly. With this move we can move the VSS files back out of 'tools', and drop the extra handling from MSI target in Makefile. Now we can build qemu-ga MSI package with: ./configure ... make qemu-ga.exe make msi or simply: ./configure ... make msi and no longer need to do a full build beforehand.

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.

2014-06-23qapi script: add event supportWenchao Xia
qapi-event.py will parse the schema and generate qapi-event.c, then the API in qapi-event.c can be used to handle events in qemu code. All API have prefix "qapi_event". The script mainly includes two parts: generate API for each event define, generate an enum type for all defined events. Since in some cases the real emit behavior may change, for example, qemu-img would not send a event, a callback layer is used to control the behavior. As a result, the stubs at compile time can be saved, the binding of block layer code and monitor code will become looser.

2014-06-23qapi: Add includes from qapi/ as dependenciesMax Reitz
qapi-schema.json has been split into three smaller JSON files in qapi/. Add them as dependencies for the code generation in the Makefile, so changes to them will result in a rebuilt of all QAPI-dependent code.

2014-06-09trace: Multi-backend tracingLluís Vilanova
Adds support to compile QEMU with multiple tracing backends at the same time. For example, you can compile QEMU with: $ ./configure --enable-trace-backends=ftrace,dtrace Where 'ftrace' can be handy for having an in-flight record of events, and 'dtrace' can be later used to extract more information from the system. This patch allows having both available without recompiling QEMU. Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
