tools lib traceevent: Export dynamic symbols used by traceevent plugins

2015-06-08T13:30:31Z

Traceevent plugins need dynamic symbols exported from libtraceevent.a, otherwise a dlopen error will occur during plugins loading. This patch uses dynamic-list-file to export dynamic symbols which will be used in plugins to perf executable. The problem is covered up if feature-libpython is enabled, because PYTHON_EMBED_LDOPTS contains '-Xlinker --export-dynamic' which adds all symbols to the dynamic symbol table. So we should reproduce the problem by setting NO_LIBPYTHON=1. Before this patch: (Prepare plugins) $ ls /root/.traceevent/plugins/ plugin_sched_switch.so plugin_function.so ... $ perf record -e 'ftrace:function' ls $ perf script Warning: could not load plugin '/mnt/data/root/.traceevent/plugins/plugin_sched_switch.so' /root/.traceevent/plugins/plugin_sched_switch.so: undefined symbol: pevent_unregister_event_handler Warning: could not load plugin '/root/.traceevent/plugins/plugin_function.so' /root/.traceevent/plugins/plugin_function.so: undefined symbol: warning ... :1049 1049 [000] 9666.754487: ftrace:function: ffffffff8118bc50 <-- ffffffff8118c5b3 :1049 1049 [000] 9666.754487: ftrace:function: ffffffff818e2440 <-- ffffffff8118bc75 :1049 1049 [000] 9666.754487: ftrace:function: ffffffff8106eee0 <-- ffffffff811212e2 After this patch: $ perf record -e 'ftrace:function' ls $ perf script :1049 1049 [000] 9666.754487: ftrace:function: __set_task_comm :1049 1049 [000] 9666.754487: ftrace:function: _raw_spin_lock :1049 1049 [000] 9666.754487: ftrace:function: task_tgid_nr_ns ...

tools lib traceevent: Install libtraceevent.a into libdir

2015-05-18T15:36:25Z

Before this patch, 'make install' installs libraries into bindir: $ make install DESTDIR=./tree INSTALL trace_plugins INSTALL libtraceevent.a INSTALL libtraceevent.so $ find ./tree ./tree/ ./tree/usr ./tree/usr/local ./tree/usr/local/bin ./tree/usr/local/bin/libtraceevent.a ./tree/usr/local/bin/libtraceevent.so ... /usr/local/lib( or lib64) should be a better place. This patch replaces 'bin' with libdir. For __LP64__ building, libraries are installed to /usr/local/lib64. For other building, to /usr/local/lib instead. After applying this patch: $ make install DESTDIR=./tree INSTALL trace_plugins INSTALL libtraceevent.a INSTALL libtraceevent.so $ find ./tree ./tree ./tree/usr ./tree/usr/local ./tree/usr/local/lib64 ./tree/usr/local/lib64/libtraceevent.a ./tree/usr/local/lib64/traceevent ./tree/usr/local/lib64/traceevent/plugins ./tree/usr/local/lib64/traceevent/plugins/plugin_mac80211.so ./tree/usr/local/lib64/traceevent/plugins/plugin_hrtimer.so ... ./tree/usr/local/lib64/libtraceevent.so Signed-off-by: Wang Nan Acked-by: Jiri Olsa Acked-by: Steven Rostedt Cc: Alexei Starovoitov Cc: Brendan Gregg Cc: Daniel Borkmann Cc: David Ahern Cc: Masami Hiramatsu Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Cc: pi3orama@163.com Cc: Zefan Li Link: http://lkml.kernel.org/r/1431860222-61636-4-git-send-email-wangnan0@huawei.com Signed-off-by: Arnaldo Carvalho de Melo

tools lib traceevent: Add alias field to struct format_field

2015-04-29T13:37:45Z

Introduce an 'alias' field to 'struct format_field' to be able to use alternative name for the field. It is initialized with same string pointer as 'name' field. The free logic checks the 'alias' pointer being reset by user and frees it. This will be handy when converting data into CTF, where each field within event needs to have a unique name (while this is not required for tracepoint). Converter can easily assign unique name into the format_field struct.
