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>

2014-05-24configure: Put tempfiles in a subdir of the build directoryPeter Maydell
When libtool support was added to configure, the new temporary files were left out of the list of files cleaned up on exit; this results in a lot of stale .lo files being left around in /tmp. Worse, libtool creates a /tmp/.libs directory which we can't easily clean up. Put all our temporary files in a single temporary directory created as a subdirectory of the build directory, so we can easily clean it up, and don't need fragile or complicated code for creation to avoid it clashing with temporary directories from other instances of QEMU configure or being subject to attack from adversaries who can write to /tmp. Since the temporaries now live in the build tree, we have no need to jump through hoops with a trap handler to try to remove them when configure exits; this fixes some weird bugs where hitting ^C during a configure run wouldn't actually make it stop, because we would run the trap handler but then not stop. (It is possible to get the trap handler semantics right but it is convoluted largely because of bugs in dash, so it is simpler to just avoid it.) Note that "temporary files go in the build directory, not /tmp" is the way autoconf behaves.

2014-05-24configure: Automatically select GTK+ 3.0 if GTK+ 2.0 is unavailableStefan Weil
The configure option --with-gtkabi=3.0 is still supported, but no longer needed when GTK+-2.0 is missing. When no GTK+ ABI is selected by the user, configure first tries 2.0, then 3.0. For some platforms (e.g. Windows) newer binaries of GTK+ are only available for GTK+ 3.0. Now building on these platforms is a little bit easier.

Use the cflags only where really used (for two mentioned files), and libs only where needed. While at it, rename variables to better reflect reality: libcacard_* is really nss_*. This needs a bit more tweaking: $(NSS_LIBS) should not contain $glib_libs (ditto for _cflags). But in order to fix it, some more preparations should be made first. So add a FIXME comment.

2014-05-07configure: make source tree build more robustMichael S. Tsirkin
When source directory can be arrived at by two paths, configure might misdetect an out of tree build. The simplest way to trigger the problem is running configure using a full path. E.g. (<firstpath> refers to qemu source tree): ln -s <firstpath> <secondpath> cd <firstpath> <secondpath>/configure A more practical way is when make runs configure automatically: 1. cd <firstpath>/; ./configure SRC_PATH=<firstpath>/ is written into config_host.mak 2. cd <secondpath>/; touch configure; make make now runs <firstpath>/configure, so configure assumes it's an out of tree build When this happens configure overwrites parts of the current tree with symlinks. Make the test more robust: look for configure in the current directory. If there - we know it's a source build! Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2014-05-02linux-user: remove configure option for setting uname releaseRiku Voipio
--enable-uname-release was a rather heavyweight hammer, as it allows providing values less that UNAME_MINIMUM_RELEASE. Also, it affects all built linux-user targets, which in most cases is not what user wants. Now that we have UNAME_MINIMUM_RELEASE for all linux-user platforms, we can drop --enable-uname-release and the related CONFIG_UNAME_RELEASE define. Users can still override the variable with QEMU_UNAME=2.6.32 or -r command line option. If distributors need to update a minimum version for a specific target, it can be done by updating UNAME_MINIMUM_RELEASE. Signed-off-by: Riku Voipio <riku.voipio@linaro.org>

2014-03-06configure: Always build with -fno-commonPeter Maydell
MacOSX doesn't pull .o files from .a archives if the symbol that it requires is one which the .o file defines as a common symbol. (Common symbols are those declared without "extern"; the linker will merge together common symbols with the same name, so redeclaring the same variable in two compilation units results in them referring to the same symbol rather than a compilation error). This MacOSX difference from traditional linker behaviour means that "make check" produces link errors: Undefined symbols for architecture x86_64: "_cur_mon", referenced from: _error_vprintf in libqemuutil.a(qemu-error.o) _error_printf in libqemuutil.a(qemu-error.o) _error_printf_unless_qmp in libqemuutil.a(qemu-error.o) _error_print_loc in libqemuutil.a(qemu-error.o) _error_report in libqemuutil.a(qemu-error.o) ld: symbol(s) not found for architecture x86_64 in this case because "cur_mon" is a common symbol in libqemustub.a(mon-set-error.o). In QEMU we don't make any use at all of the common symbol functionality, so we can avoid this problem entirely simply by compiling with -fno-common. Enable this option for all builds, not just MacOSX, so that if we ever inadvertently introduce multiple definitions of some variable that will be immediately spotted as a build error rather than only breaking the MacOSX build.

This filtering was already being done for uses of C++ in the build itself, but was omitted for the "does C++ work?" configure test. This only showed up when doing builds which explicitly enabled -Werror with --enable-werror, because the "do the compilers work" tests were mistakenly placed above the "default werror based on whether compiling from git" code. Another error in this category is that clang warns if you ask it to compile C++ code from a file named "foo.c". Further, because we were running do_cc in a subshell in the condition part of an "if", the error_exit inside do_compiler wouldn't terminate configure and we would plunge on regardless. Fix this complex of errors: 1. Move the default-werror code up so that there are no invocations of compile_object and friends between it and the point where we set $werror explicitly based on the --enable-werror command line option. 2. Provide a mechanism for filtering QEMU_CFLAGS to create QEMU_CXXFLAGS, and use it for the test we run here. 3. Provide a do_cxx function to run a test with the C++ compiler rather than doing cute tricks with subshells and do_cc. 4. Use a new temporary file TMPCXX for the C++ program fragment.

2014-03-05ui/sdl2 : initial port to SDL 2.0 (v2.0)Dave Airlie
I've ported the SDL1.2 code over, and rewritten it to use the SDL2 interface. The biggest changes were in the input handling, where SDL2 has done a major overhaul, and I've had to include a generated translation file to get from SDL2 codes back to qemu compatible ones. I'm still not sure how the keyboard layout code works in qemu, so there may be further work if someone can point me a test case that works with SDL1.2 and doesn't with SDL2. Some SDL env vars we used to set are no longer used by SDL2, Windows, OSX support is untested, I don't think we can link to SDL1.2 and SDL2 at the same time, so I felt using --with-sdlabi=2.0 to select the new code should be fine, like how gtk does it. v1.1: fix keys in text console v1.2: fix shutdown, cleanups a bit of code, support ARGB cursor v2.0: merge the SDL multihead patch into this, g_new the number of consoles needed, wrap DCL inside per-console structure.

Add support for AArch32 CRC32 and CRC32C instructions added in ARMv8 and add a CPU feature flag to enable these instructions. The CRC32-C implementation used is the built-in qemu implementation and The CRC-32 implementation is from zlib. This requires adding zlib to LIBS to ensure it is linked for the linux-user binary.

2014-02-25modules: do not include gmodule-2.0 in static buildsPaolo Bonzini
gmodule-2.0's pkg-config files include -Wl,--export-dynamic, which breaks static builds. It is a glib bug, but we need to support --static builds for the linux-user targets, and in the end all that is needed to fix this is: * outlaw --enable-modules --static, which makes little sense anyway * only include gmodule-2.0's cflags and ldflags if --enable-modules is specified on the command line.

2014-02-25net: Disable netmap backend when not supportedVincenzo Maffione
This patch fixes configure so that the netmap backend is not compiled in if the host doesn't support an API version >= 11. A version upper bound (15) has been added so that the netmap API can be extended with some minor features without requiring QEMU code modifications. Moreover, some changes have been done to net/netmap.c in order to reflect the current netmap API/ABI (11). The NETMAP_WITH_LIBS macro makes possible to include some utilities (e.g. netmap ring macros, D(), RD() and other high level functions) through the netmap headers. In this way we get rid of the D and RD macro definitions in the QEMU code, and we open the way for further code simplifications that will be introduced by future patches.

2014-02-24configure: check that C++ compiler actually worksPeter Maydell
Check that the C++ compiler works with the C compiler; if it does not, then don't pass CXX to the build process. This fixes a regression where QEMU was no longer building if the build environment didn't have a C++ compiler (introduced in commit 3144f78b, which incorrectly assumed that rules.mak would only see a non-empty $(CXX) if configure had actually found a working C++ compiler).

2014-02-21quorum: Add quorum mechanism.Benoît Canet
This patchset enables the core of the quorum mechanism. The num_children reads are compared to get the majority version and if this version exists more than threshold times the guest won't see the error at all. If a block is corrupted or if an error occurs during an IO or if the quorum cannot be established QMP events are used to report to the management. Use gnutls's SHA-256 to compare versions. --enable-quorum must be used to enable the feature.
