2016-10-12trace: get rid of generated-events.h/generated-events.cDaniel P. Berrange
Currently the generated-events.[ch] files contain the event dstates, constants and TraceEvent structs, while the generated-tracers.[ch] files contain the actual trace probe logic. With the removal of usage of the event enums from the API there is no longer any compelling reason for the separation between these files. The generated-events.h content is only ever needed from the generated-tracers.[ch] files. The enums/constants/structs from generated-events.[ch] are thus moved into the generated-tracers.[ch], so that there is one less file to be generated.

2016-10-06rules.mak: quiet-command: Split command name and args to printPeter Maydell
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".

2016-09-20blockdev: Add dynamic module loading for block driversMarc Mari
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.

It could be solved with an 'override' directive on CFLAGS, but that would actually prevent setting different CFLAGS manually.

2016-06-01Makefile: Rules for docker testingFam Zheng
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.

2016-05-23Remove config-devices.mak on 'make clean'Peter Maydell
Our dependency mechanism works like this: * 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.)

2016-03-10osdep: add wrappers for socket functionsDaniel P. Berrange
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.

2016-02-16nbd: convert block client to use I/O channels for connection setupDaniel P. Berrange
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. Signed-off-by: Daniel P.

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>
