Enable KVM if the host and target CPU are both aarch64. Note that host aarch64 + target arm is not valid for KVM acceleration: the 64 bit kernel does not support the ioctl interface for 32 bit CPUs. 32 bit VMs on 64 bit hosts need to be created using the 64 bit ioctl interface; when QEMU supports this it will be on the arch64-softmmu target with a -cpu parameter for a 32 bit CPU, which is still an aarch64/aarch64 combination as far as configure is concerned.

2013-12-09net: Adding netmap network backendVincenzo Maffione
This patch adds support for a network backend based on netmap. netmap is a framework for high speed packet I/O. You can use it to build extremely fast traffic generators, monitors, software switches or network middleboxes. Its companion software switch VALE lets you interconnect virtual machines. netmap and VALE are implemented as a non-intrusive kernel module, support NICs from multiple vendors, are part of standard FreeBSD distributions and available in source format for Linux too. To compile QEMU with netmap support, use the following configure options: ./configure [...] --enable-netmap --extra-cflags=-I/path/to/netmap/sys where "/path/to/netmap" contains the netmap source code, available at http://info.iet.unipi.it/~luigi/netmap/ The same webpage contains more information about the netmap project (together with papers and presentations).

2013-11-21configure: Explicitly set ARFLAGS so we can build with GNU Make 4.0Peter Maydell
Our rules.mak adds '-rR' to MAKEFLAGS to indicate that we will be explicitly specifying everything and not relying on any default variables or rules. However we were accidentally relying on the default ARFLAGS ("rv"). This went unnoticed because of a bug in GNU Make 3.82 and earlier which meant that adding -rR to MAKEFLAGS only affected submakes, not the currently running instance. Explicitly set ARFLAGS in config-host.mak, in the same way we handle CFLAGS and LDFLAGS; this will allow us to work with Make 4.0. Thanks to Paul Smith for analyzing this bug for us.

Commit 1d984a67a95d88f3e708b077dab8adeb47c38c93 added the -B switch unconditionally. This breaks Python versions before 2.6 which don't support that switch. Now configure adds -B only if it is accepted by the Python interpreter.

2013-09-12coroutine: add ./configure --disable-coroutine-poolStefan Hajnoczi
The 'gthread' coroutine backend was written before the freelist (aka pool) existed in qemu-coroutine.c. This means that every thread is expected to exit when its coroutine terminates. It is not possible to reuse threads from a pool. This patch automatically disables the pool when 'gthread' is used. This allows the 'gthread' backend to work again (for example, tests/test-coroutine completes successfully instead of hanging). I considered implementing thread reuse but I don't want quirks like CPU affinity differences due to coroutine threads being recycled. The 'gthread' backend is a reference backend and it's therefore okay to skip the pool optimization. Note this patch also makes it easy to toggle the pool for benchmarking purposes: ./configure --with-coroutine-backend=ucontext \ --disable-coroutine-pool Reported-by: Gabriel Kerneis <gabriel@kerneis.info> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Gabriel Kerneis <gabriel@kerneis.info> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2013-09-09qemu-ga: Add Windows VSS provider and requester as DLLTomoki Sekiyama
Adds VSS provider and requester as a qga-vss.dll, which is loaded by Windows VSS service as well as by qemu-ga. "provider.cpp" implements a basic stub of a software VSS provider. Currently, this module only relays a frozen event from VSS service to the agent, and thaw event from the agent to VSS service, to block VSS process to keep the system frozen while snapshots are taken at the host. To register the provider to the guest system as COM+ application, the type library (.tlb) for qga-vss.dll is required. To build it from COM IDL (.idl), VisualC++, MIDL and stdole2.tlb in Windows SDK are required. This patch also adds pre-compiled .tlb file in the repository in order to enable cross-compile qemu-ga.exe for Windows with VSS support. "requester.cpp" provides the VSS requester to kick the VSS snapshot process. Qemu-ga.exe works without the DLL, although fsfreeze features are disabled. These functions are only supported in Windows 2003 or later. In older systems, fsfreeze features are disabled. In several versions of Windows which don't support attribute VSS_VOLSNAP_ATTR_NO_AUTORECOVERY, DoSnapshotSet fails with error VSS_E_OBJECT_NOT_FOUND. In this patch, we just ignore this error. To solve this fundamentally, we need a framework to handle mount writable snapshot on guests, which is required by VSS auto-recovery feature (cleanup phase after a snapshot is taken).

2013-09-09qemu-ga: Add configure options to specify path to Windows/VSS SDKTomoki Sekiyama
To enable VSS support in qemu-ga for Windows, header files included in VSS SDK are required. The VSS support is enabled by the configure option like below: ./configure --with-vss-sdk="/path/to/VSS SDK" If the path is omitted, it tries to search the headers from default paths and VSS support is enabled only if the SDK is found. VSS support is disabled if --without-vss-sdk or --with-vss-sdk=no is specified. VSS SDK is available from: http://www.microsoft.com/en-us/download/details.aspx?id=23490 To cross-compile using mingw, you need to setup the SDK on Windows environments to extract headers. You can also extract the SDK headers on POSIX environments using scripts/extract-vss-headers and msitools. In addition, --with-win-sdk="/path/to/Windows SDK" option is also added to specify path to Windows SDK, which may be used for native-compile of .tlb file of qemu-ga VSS provider. However, this is usually unnecessary because pre-compiled .tlb file is included.

2013-09-09configure: Support configuring C++ compilerTomoki Sekiyama
Add configuration for C++ compiler in configure and Makefiles. The C++ compiler is choosed as following: - ${CXX}, if it is specified. - ${cross_prefix}g++, if ${cross_prefix} is specified. - Otherwise, c++ is used. Currently, usage of C++ language is only for access to Windows VSS using COM+ services in qemu-guest-agent for Windows.

2013-09-01configure: Remove unneeded redirections of stderr (pkg-config --exists)Stefan Weil
Predicate options (--exists, --atleast-version, ...) of pkg-config dont't print error messages to stderr, so redirecting stderr is not necessary. Combining a predicate option with --modversion is not necessary for tests. Instead of testing with --modversion, --exists can be used.

2013-09-01configure: Don't write .pyc files by default (python -B)Stefan Weil
When a Python script is run, Python normally writes bytecode into a .pyc file. QEMU's build process uses several Python scripts which are called from configure or make. The generated .pyc files take disk space without being of much use, because those scripts are short, not time critical and only called a few times. Python's option -B disables writing of .pyc files. QEMU now uses "python -B" as default, but it is still possible to choose a different call by passing --python=PYTHON to configure.

2013-09-01configure: disable clang -Wstring-plus-int warningPeter Maydell
Some versions of clang will warn about adding integers to strings: disas/i386.c:4753:23: error: adding 'char' to a string does not append to the string [-Werror,-Wstring-plus-int] oappend ("%es:" + intel_syntax); ~~~~~~~^~~~~~~~~~~~~~ disas/i386.c:4753:23: note: use array indexing to silence this warning oappend ("%es:" + intel_syntax); ^ & [ ] disas/i386.c uses this idiom to to skip a "%" prefix if using intel rather than AT&T syntax. This seems like a reasonable thing to do, and I don't think anybody contributing to QEMU is likely to believe that '+' is a string concatenation operator in C, so just disable -Wstring-plus-int.
