[PATCH 2/3] perf build: Use libtraceevent from the system

Ian Rogers
2022-12-05T23:00:53Z

Remove the LIBTRACEEVENT_DYNAMIC and LIBTRACEFS_DYNAMIC. 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_TRACEEVENT 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".
