2021-02-01trace: add meson custom_target() depend_files for tracetoolStefan Hajnoczi1-7/+14
Re-generate tracetool output when the tracetool source code changes. Use the same approach as qapi_gen_depends and introduce a tracetool_depends files list so meson is aware of the dependencies.

2020-12-19qapi: Use QAPI_LIST_PREPEND() where possibleEric Blake1-12/+10
Anywhere we create a list of just one item or by prepending items (typically because order doesn't matter), we can use QAPI_LIST_PREPEND(). But places where we must keep the list in order by appending remain open-coded until later patches. Note that as a side effect, this also performs a cleanup of two minor issues in qga/commands-posix.c: the old code was performing new = g_malloc0(sizeof(*ret)); which 1) is confusing because you have to verify whether 'new' and 'ret' are variables with the same type, and 2) would conflict with C++ compilation (not an actual problem for this file, but makes copy-and-paste harder).

2020-11-19trace: use STAP_SDT_V2 to work around symbol visibilityStefan Hajnoczi1-2/+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.

2020-10-26trace/simple: Enable tracing on startup only if the user specifies a trace ↵Josh DuBois1-1/+5
option Tracing can be enabled at the command line or via the monitor. Command-line trace options are recorded during trace_opt_parse(), but tracing is not enabled until the various front-ends later call trace_init_file(). If the user passes a trace option on the command-line, remember that and enable tracing during trace_init_file(). Otherwise, trace_init_file() should record the trace file specified by the frontend and avoid enabling traces until the user requests them via the monitor. This fixes 1b7157be3a8c4300fc8044d40f4b2e64a152a1b4 and also db25d56c014aa1a96319c663e0a60346a223b31e, by allowing the user to enable traces on the command line and also avoiding unwanted trace-<pid> files when the user has not asked for them.

2020-08-21libqemuutil, qapi, trace: convert to mesonPaolo Bonzini2-51/+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.

2020-08-21trace: switch position of headers to what Meson requiresPaolo Bonzini2-2/+2
Meson doesn't enjoy the same flexibility we have with Make in choosing the include path. In particular the tracing headers are using $(build_root)/$(<D). In order to keep the include directives unchanged, the simplest solution is to generate headers with patterns like "trace/trace-audio.h" and place forwarding headers in the source tree such that for example "audio/trace.h" includes "trace/trace-audio.h". This patch is too ugly to be applied to the Makefiles now. It's only a way to separate the changes to the tracing header files from the Meson rewrite of the tracing logic.

2019-08-27trace: Clarify DTrace/SystemTap help messagePhilippe Mathieu-Daudé1-0/+6
Most tracing backends are implemented within QEMU, except the DTrace/SystemTap backends. One side effect is when running 'qemu -trace help', an incomplete list of trace events is displayed when using the DTrace/SystemTap backends. This is partly due to trace events registered as modules with trace_init(), and since the events are not used within QEMU, the linker optimize and remove the unused modules (which is OK in this particular case). Currently only the events compiled in trace-root.o and in the last trace.o member of libqemuutil.a are linked, resulting in an incomplete list of events. To avoid confusion, improve the help message, recommending to use the proper systemtap script to display the events list.

2019-08-16trace: Do not include qom/cpu.h into generated trace.hMarkus Armbruster4-50/+64
docs/devel/tracing.txt explains "since many source files include trace.h, [the generated trace.h use] a minimum of types and other header files included to keep the namespace clean and compile times and dependencies down." Commit 4815185902 "trace: Add per-vCPU tracing states for events with the 'vcpu' property" made them all include qom/cpu.h via control-internal.h. qom/cpu.h in turn includes about thirty headers. Ouch. Per-vCPU tracing is currently not supported in sub-directories' trace-events. In other words, qom/cpu.h can only be used in trace-root.h, not in any trace.h. Split trace/control-vcpu.h off trace/control.h and trace/control-internal.h. Have the generated trace.h include trace/control.h (which no longer includes qom/cpu.h), and trace-root.h include trace/control-vcpu.h (which includes it). The resulting improvement is a bit disappointing: in my "build everything" tree, some 1100 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h) depend on a trace.h, and about 600 of them no longer depend on qom/cpu.h. But more than 1300 others depend on trace-root.h. More work is clearly needed. Left for another day.

Per supported platforms doc[1], the various min glib on relevant distros is: RHEL-7: 2.50.3 Debian (Stretch): 2.50.3 Debian (Jessie): 2.42.1 OpenBSD (Ports): 2.54.3 FreeBSD (Ports): 2.50.3 OpenSUSE Leap 15: 2.54.3 SLE12-SP2: 2.48.2 Ubuntu (Xenial): 2.48.0 macOS (Homebrew): 2.56.0 This suggests that a minimum glib of 2.42 is a reasonable target. The GLibC compile farm, however, uses Ubuntu 14.04 (Trusty) which only has glib 2.40.0, and this is needed for testing during merge. Thus an exception is made to the documented platform support policy to allow for all three current LTS releases to be supported. Docker jobs that not longer satisfy this new min version are removed.

2018-06-28move public invalidate APIs out of translate-all.{c,h}, clean upPaolo Bonzini1-1/+0
Place them in exec.c, exec-all.h and ram_addr.h. This removes knowledge of translate-all.h (which is an internal header) from several files outside accel/tcg and removes knowledge of AddressSpace from translate-all.c (as it only operates on ram_addr_t).

2018-06-27trace: simplify trace_mem functionsEmilio G. Cota2-23/+19
Add some defines for the mem_info bits, simplify trace_mem_build_info, and also simplify trace_mem_get_info by making it a wrapper around trace_mem_build_info. This paves the way for increasing size_shift by one bit. Signed-off-by: Emilio G.

2018-03-02Include less of the generated modular QAPI headersMarkus Armbruster1-1/+1
In my "build everything" tree, a change to the types in qapi-schema.json triggers a recompile of about 4800 out of 5100 objects. The previous commit split up qmp-commands.h, qmp-event.h, qmp-visit.h, qapi-types.h. Each of these headers still includes all its shards. Reduce compile time by including just the shards we actually need. To illustrate the benefits: adding a type to qapi/migration.json now recompiles some 2300 instead of 4800 objects. The next commit will improve it further.

2018-02-09Move include qemu/option.h from qemu-common.h to actual usersMarkus Armbruster1-0/+1
qemu-common.h includes qemu/option.h, but most places that include the former don't actually need the latter. Drop the include, and add it to the places that actually need it. While there, drop superfluous includes of both headers, and separate #include from file comment with a blank line. This cleanup makes the number of objects depending on qemu/option.h drop from 4545 (out of 4743) to 284 in my "build everything" tree.

2017-12-18trace: Try using tracefs firstNamhyung Kim1-6/+12
Recent Linux kernel provides separate tracefs which doesn't need to be mounted on the debugfs. Although most systems mount it at the traditional place on the debugfs, it'd be safer to check tracefs first.
