perf ftrace: Introduce new 'ftrace' tool The 'perf ftrace' command is a simple wrapper of kernel's ftrace functionality. It only supports single thread tracing currently and just reads trace_pipe in text and then write it to stdout.

perf build: Use libtraceevent from the system Remove the LIBTRACEEVENT_DYNAMIC and LIBTRACEFS_DYNAMIC make command line variables. If libtraceevent isn't installed or NO_LIBTRACEEVENT=1 is passed to the build, don't compile in libtraceevent and libtracefs support. This also disables CONFIG_TRACE that controls "perf trace". CONFIG_LIBTRACEEVENT is used to control enablement in Build/Makefiles, HAVE_LIBTRACEEVENT is used in C code. Without HAVE_LIBTRACEEVENT tracepoints are disabled and as such the commands kmem, kwork, lock, sched and timechart are removed. The majority of commands continue to work including "perf test". Committer notes: Fixed up a tools/perf/util/Build reject and added: #include <traceevent/event-parse.h> to tools/perf/util/scripting-engines/trace-event-perl.c.

Building with NO_LIBTRACEEVENT=1 uncovered some more build failures: - Make building of data-convert-bt.c to CONFIG_LIBTRACEEVENT=y - perf-$(CONFIG_LIBTRACEEVENT) += scripts/ - bpf_kwork.o needs also to be dependent on CONFIG_LIBTRACEEVENT=y - The python binding needed some fixups and util/trace-event.c can't be built and linked with the python binding shared object, so remove it in tools/perf/util/setup.py and exclude it from the list of dependencies in the python/perf.so Makefile.perf target. Building without libtraceevent-devel installed uncovered more build failures: - The python binding tools/perf/util/python.c was assuming that traceevent/parse-events.h was always available, which was the case when we defaulted to using the in-kernel tools/lib/traceevent/ files, now we need to enclose it under ifdef HAVE_LIBTRACEEVENT, just like the other parts of it that deal with tracepoints. - We have to ifdef the rules in the Build files with CONFIG_LIBTRACEEVENT=y to build builtin-trace.c and tools/perf/trace/beauty/ as we only ifdef setting CONFIG_TRACE=y when setting NO_LIBTRACEEVENT=1 in the make command line, not when we don't detect libtraceevent-devel installed in the system. Simplification here to avoid these two ways of disabling builtin-trace.c and not having CONFIG_TRACE=y when libtraceevent-devel isn't installed is the clean way. From Athira: <quote> tools/perf/arch/powerpc/util/Build -perf-y += kvm-stat.o +perf-$(CONFIG_LIBTRACEEVENT) += kvm-stat.o </quote> Then, ditto for arm64 and s390, detected by container cross build tests. - s/390 uses test__checkevent_tracepoint() that is now only available if HAVE_LIBTRACEEVENT is defined, enclose the callsite with ifder HAVE_LIBTRACEEVENT. Also from Athira: <quote> With this change, I could successfully compile in these environment: - Without libtraceevent-devel installed - With libtraceevent-devel installed - With “make NO_LIBTRACEEVENT=1” </quote> Then, finally rename CONFIG_TRACEEVENT to CONFIG_LIBTRACEEVENT for consistency with other libraries detected in tools/perf/.

perf script: Fix Python support when no libtraceevent Python scripting can be used without libtraceevent. In particular, scripting for Intel PT does not use tracepoints, and so does not need libtraceevent support. Alter the build and employ conditional compilation to allow Python scripting without libtraceevent. Example: Before: $ ldd `which perf` | grep -i python $ ldd `which perf` | grep -i libtraceevent $ perf record -e intel_pt//u uname Linux [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.031 MB perf.data ] $ perf script intel-pt-events.py |& head -3 Error: Couldn't find script `intel-pt-events.py' See perf script -l for available scripts. After: $ ldd `which perf` | grep -i python libpython3.10.so.1.0 => /lib/x86_64-linux-gnu/libpython3.10.so.1.0 (0x00007f4bac400000) $ ldd `which perf` | grep -i libtraceevent $ perf script intel-pt-events.py | head Intel PT Branch Trace, Power Events, Event Trace and PTWRITE Switch In 8021/8021 [000] 11234.097713404 0/0 perf-exec 8021/8021 [000] 11234.098041726 psb offset: 0x0 0 [unknown] ([unknown]) perf-exec 8021/8021 [000] 11234.098041726 cbr 45 freq: 4505 MHz (161%) 0 [unknown] ([unknown]) uname 8021/8021 [000] 11234.098082170 branches:uH tr strt 0 [unknown] ([unknown]) => 7f3a8b9422b0 _start+0x0 (/usr/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2) uname 8021/8021 [000] 11234.098082379 branches:uH tr end 7f3a8b9422b0 _start+0x0 (/usr/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2) => 0 [unknown] ([unknown]) uname 8021/8021 [000] 11234.098083629 branches:uH tr strt 0 [unknown] ([unknown]) => 7f3a8b9422b0 _start+0x0 (/usr/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2) uname 8021/8021 [000] 11234.098083629 branches:uH call 7f3a8b9422b3 _start+0x3 (/usr/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2) => 7f3a8b943050 _dl_start+0x0 (/usr/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2) uname 8021/8021 [000] 11234.098083837 branches:uH tr end 7f3a8b943060 _dl_start+0x10 (/usr/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2) => 0 [unknown] ([unknown]) IPC: 0.01 (9/938) uname 8021/8021 [000] 11234.098084670 branches:uH tr strt 0 [unknown] ([unknown]) => 7f3a8b943060 _dl_start+0x10 (/usr/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2) Fixes: 378ef0f5d9d7f465 ("perf build: Use libtraceevent from the system") Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Cc: Ian Rogers <irogers@google.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Link: https://lore.kernel.org/r/20230315084321.14563-1-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
