2015-06-17qemu-ga: Building Windows MSI installation with configure/MakefileYossi Hindin
New options were added to enable Windows MSI installation package creation: Option --enable-guest-agent-msi, like the name suggests, enables building Windows MSI package for QEMU guest agent; option --disable-guest-agent-msi disables MSI package creation; by default, no MSI package is created Signed-off-by: Yossi Hindin <yhindin@redhat.com> Message-Id: <1430913460-13174-5-git-send-email-yhindin@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

The .d file name must match exactly what is used in the SUBDIR_DEVICES_MAK_DEP variable. Instead of making assumptions in the make_device_config.sh script, just pass it in. Similarly, the makefile target may not match the output file name, because Makefile uses a temporary file.

2015-02-27Makefile: fix up parallel building under MSYS+MinGWVasily Efimov
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, see: "http://sourceforge.net/p/mingw/bugs/1950/". The suggested version is 1.0.17.

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.

2014-06-09trace: 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.

With this, modules built from a different tree/version/configure will not be loaded. The module loading code requires gmodule-2.0. Modules are searched under - CONFIG_MODDIR - executable folder (to allow running qemu-{img,io} in the build directory) - ../ of executable folder (to allow running system emulator in the build directory) Modules are linked under their subdir respectively, then copied to top level of build directory for above convinience, e.g.: $(BUILD_DIR)/block/curl.so -> $(BUILD_DIR)/block-curl.so Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

It's linked to "-shared" with all its dependencies (multiple *.o) as input. Which means the list of depended objects must be specified in each sub-Makefile.objs: foo.mo-objs := bar.o baz.o qux.o in the same style with foo.o-cflags and foo.o-libs. The objects here will be prefixed with "$(obj)/" if it's a subdirectory Makefile.objs. 3) For all files ending up in %.so, the following is added automatically: foo.o-cflags += -fPIC -DBUILD_DSO Also introduce --enable-modules in configure, the option will enable support of shared object build.

This doesn't hurt compiling because we basically build all .o from top Makefile, before entering Makefile.target, but it will affact arriving per-object libs support.

Upstream OpenBIOS now implements SBus probing in order to determine the contents of a physical bus slot, which is required to allow OpenBIOS to identify the framebuffer without help from the fw_cfg interface. SBus probing works by detecting the presence of an FCode program (effectively tokenised Forth) at the base address of each slot, and if present executes it so that it creates its own device node in the OpenBIOS device tree. The FCode ROM is generated as part of the OpenBIOS build and should generally be updated at the same time.
