* tracing: excise the tcg related from tracetoolAlex Bennée2022-02-091-13/+0Star
| | | | | | | | | | | | | | Now we have no TCG trace events and no longer handle them in the code we can remove the handling from the tracetool to generate them. vcpu tracing is still available although the existing syscall event is an exercise in redundancy (plugins and -strace can also get the information).

Define global qapi_trace_events list of .trace-events file targets, to fill in trace/qapi.build and to use in trace/meson.build 4.

* meson: switch minimum meson version to 0.58.2, minimum recommended to 0.59.2Paolo Bonzini2021-10-051-2/+2
| | | | | | | | | | | | | | Meson 0.58.2 does not need b_staticpic=$pie anymore, and has stabilized the keyval module. Remove the workaround and use a few replacements for features deprecated in the 0.57.0 release cycle. One feature that we would like to use is passing dependencies to summary. However, that was broken in 0.59.0 and 0.59.1. Therefore, use the embedded Meson if the host has anything older than 0.59.2, but allow --meson= to use 0.58.2.

* trace, lttng: require .pc filesPaolo Bonzini2021-07-121-1/+1
| | | | | | | | | | | | | | The next version of lttng-libs will not require liburcu at run time anymore. Therefore, it is expected that distros will not include the urcubp libraries anymore when installing lttng-ust-devel. To avoid future problems, just require pkg-config to detect lttng-ust. The .pc files for lttng-ust correctly include liburcubp.a for static builds, and have always done since pkg-config files were added in 2011.

* | tracetool: add output filename command-line argumentStefan Hajnoczi2021-01-041-14/+7Star
|/ | | | | | | | | | | | | | The tracetool.py script writes to stdout. This means the output filename is not available to the script. Add the output filename to the command-line so that the script has access to the filename. This also simplifies the tracetool.py invocation. It's no longer necessary to use meson's custom_build(capture : true) to save output.

* trace: use STAP_SDT_V2 to work around symbol visibilityStefan Hajnoczi2020-11-191-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QEMU binaries no longer launch successfully with recent SystemTap releases. This is because modular QEMU builds link the sdt semaphores into the main binary instead of into the shared objects where they are used. The symbol visibility of semaphores is 'hidden' and the dynamic linker prints an error during module loading: $ ./configure --enable-trace-backends=dtrace --enable-modules ... ... Failed to open module: /builddir/build/BUILD/qemu-4.2.0/s390x-softmmu/../block-curl.so: undefined symbol: qemu_curl_close_semaphore The long-term solution is to generate per-module dtrace .o files and link them into the module instead of the main binary. In the short term we can define STAP_SDT_V2 so dtrace(1) produces a .o file with 'default' symbol visibility instead of 'hidden'. This workaround is small and easier to merge for QEMU 5.2 and downstream backports.

* libqemuutil, qapi, trace: convert to mesonPaolo Bonzini2020-08-211-0/+76
This shows how to do some "computations" in meson.build using its array and dictionary data structures, and also a basic usage of the sourceset module for conditional compilation. Notice the new "if have_system" part of util/meson.build, which fixes a bug in the old build system was buggy: util/dbus.c was built even for non-softmmu builds, but the dependency on -lgio was lost when the linking was done through libqemuutil.a. Because all of its users required gio otherwise, the bug was hidden. Meson instead propagates libqemuutil's dependencies down to its users, and shows the problem.
