2017-03-10T01:01:09+00:00

Fix typos and add the following to the scripts/spelling.txt: overide||override While we are here, fix the doubled "address" in the touched line Documentation/devicetree/bindings/regulator/ti-abb-regulator.txt. Also, fix the comment block style in the touched hunks in drivers/media/dvb-frontends/drx39xyj/drx_driver.h.

tools lib traceevent: Robustify do_generate_dynamic_list_file

2017-02-08T13:27:45+00:00

The dynamic-list-file used to export dynamic symbols introduced in commit e3d09ec8126f ("tools lib traceevent: Export dynamic symbols used by traceevent plugins") is generated without any sort of error checking. I experienced problems due to an old version of nm (v 0.158) that outputs in a format distinct from the assumed by the script. Robustify the built of dynamic symbol list by enforcing that the second column of $(NM) -u is either "U" (Undefined), "W" or "w" (undefined weak), which are the possible outputs from non-ancient $(NM) versions. Print an error if format is unexpected. v2: Accept "W" and "w" symbol options.

make use of make variable CURDIR instead of calling pwd

2016-12-11T11:12:56+00:00

make already provides the current working directory in a variable, so make use of it instead of forking a shell. Also replace usage of PWD by CURDIR. PWD is provided by most shells, but not all, so this makes the build system more robust. Signed-off-by: Uwe Kleine-König Signed-off-by: Michal Marek

tools lib traceevent: Add version for traceevent shared object

2016-10-24T14:07:32+00:00

Adding version support for libtraceevent.so object. Using the existing EVENT_PARSE_VERSION variable to construct the .so object version string, which now consists of: $(EP_VERSION).$(EP_PATCHLEVEL).$(EP_EXTRAVERSION) Looks like it was created for this purpose anyway. The build will now produce following traeceevent libraries: $ ll libtraceevent* libtraceevent.a libtraceevent.so -> libtraceevent.so.1.1.0 libtraceevent.so.1 -> libtraceevent.so.1.1.0 libtraceevent.so.1.1.0 Also the install target will carry them: $ make DESTDIR=/tmp/krava prefix=/usr install INSTALL trace_plugins INSTALL libtraceevent.a INSTALL libtraceevent.so.1.1.0 $ find /tmp/krava/ | xargs ls -l ... /tmp/krava/usr/lib64: total 572 libtraceevent.a libtraceevent.so -> libtraceevent.so.1.1.0 libtraceevent.so.1 -> libtraceevent.so.1.1.0 libtraceevent.so.1.1.0 ...

tools lib traceevent: Export dynamic symbols used by traceevent plugins

2015-06-08T13:30:31+00:00

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 ...
