2012-11-18build: replace weak symbols with a static libraryPaolo Bonzini1-0/+5
Weak symbols were a nice idea, but they turned out not to be a good one. Toolchain support is just too sparse, in particular llvm-gcc is totally broken. This patch uses a surprisingly low-tech approach: a static library. Symbols in a static library are always overridden by symbols in an object file. Furthermore, if you place each function in a separate source file, object files for unused functions will not be taken in. This means that each function can use all the dependencies that it needs (especially QAPI stuff such as error_setg). Thus, all stubs are placed in separate object files and put together in a static library. The library then is linked to all programs.

2012-10-31aio: add generic thread-pool facilityPaolo Bonzini1-1/+1
Add a generic thread-pool. The code is roughly based on posix-aio-compat.c, with some changes, especially the following: - use QemuSemaphore instead of QemuCond; - separate the state of the thread from the return code of the worker function. The return code is totally opaque for the thread pool; - do not busy wait when doing cancellation. A more generic threadpool (but still specific to I/O so that in the future it can use special scheduling classes or PI mutexes) can have many uses: it allows more flexibility in raw-posix.c and can more easily be extended to Win32, and it will also be used to do an msync of the persistent bitmap. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-10-30aio: add Win32 implementationPaolo Bonzini1-3/+3
The Win32 implementation will only accept EventNotifiers, thus a few drivers are disabled under Windows. EventNotifiers are a good match for the GSource implementation, too, because the Win32 port of glib allows to place their HANDLEs in a GPollFD. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2012-10-23qmp: add NBD server commandsPaolo Bonzini1-1/+1
Adding an NBD server inside QEMU is trivial, since all the logic is in nbd.c and can be shared easily between qemu-nbd and QEMU itself.

2012-06-11consolidate qemu_iovec_memset{,_skip}() into single function and use ↵Michael Tokarev1-2/+2
existing iov_memset() This patch combines two functions into one, and replaces the implementation with already existing iov_memset() from iov.c. The new prototype of qemu_iovec_memset(): size_t qemu_iovec_memset(qiov, size_t offset, int fillc, size_t bytes) It is different from former qemu_iovec_memset_skip(), and I want to make other functions to be consistent with it too: first how much to skip, second what, and 3rd how many of it. It also returns actual number of bytes filled in, which may be less than the requested `bytes' if qiov is smaller than offset+bytes, in the same way iov_memset() does. While at it, use utility function iov_memset() from iov.h in posix-aio-compat.c, where qiov was used. Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>

This patch starts converting the hw/ directory. Some files in hw/ are compiled once, some twice (32-/64-bit), some once per target. Each category is moved in a separate patch. After this patch, the files that are compiled once will show the same hierarchy in the build tree as they do in the source tree, for example hw/qdev.o instead of just qdev.o.

2012-06-07build: move rules for nesting to Makefile.objsPaolo Bonzini1-0/+2
At this point we will start adding nesting behavior to other files than Makefile.target.

2012-04-18tracetool: Rewrite infrastructure as python modulesLluís Vilanova1-3/+3
The tracetool script is written in shell and has hit several portability problems due to shell quirks or external tools across host platforms. Additionally the amount of string processing and lack of real data structures makes it tough to implement code generator backends for tracers that are more complex. This patch replaces the shell version of tracetool with a Python version. The new tracetool design is: scripts/tracetool.py - top-level script scripts/tracetool/backend/ - tracer backends live here (simple, ust) scripts/tracetool/format/ - output formats live here (.c, .h) There is common code for trace-events definition parsing so that backends can focus on generating code rather than parsing input. Support for all existing backends (nop, stderr, simple, ust, and dtrace) is added back in follow-up patches.

2012-03-30qtest: add test frameworkAnthony Liguori1-0/+2
The idea behind qtest is pretty simple. Instead of executing a CPU via TCG or KVM, rely on an external process to send events to the device model that the CPU would normally generate. qtest presents itself as an accelerator. In addition, a new option is added to establish a qtest server (-qtest) that takes a character device. This is what allows the external process to send CPU events to the device model. qtest uses a simple line based protocol to send the events. Documentation of that protocol is in qtest.c. I considered reusing the monitor for this job. Adding interrupts would be a bit difficult. In addition, logging would also be difficult. qtest has extensive logging support. All protocol commands are logged with time stamps using a new command line option (-qtest-log). Logging is important since ultimately, this is a feature for debugging.
