2017-03-27perf report: Enable sorting by srcline as keyMilian Wolff1-1/+2
Often it is interesting to know how costly a given source line is in total. Previously, one had to build these sums manually based on all addresses that pointed to the same source line. This patch introduces srcline as a sort key, which will do the aggregation for us. Paired with the recent addition of showing inline frames, this makes perf report much more useful for many C++ work loads. The following shows the new feature in action. First, let's show the status quo output when we sort by address. The result contains many hist entries that generate the same output: ~~~~~~~~~~~~~~~~ $ perf report --stdio --inline -g address # Children Self Command Shared Object Symbol # ........ ........ ............ ................... ......................................... # 99.89% 35.34% cpp-inlining cpp-inlining [.] main | |--64.55%--main complex:655 | /home/milian/projects/kdab/rnd/hotspot/tests/test-clients/cpp-inlining/main.cpp:39 (inline) | /usr/include/c++/6.3.1/complex:664 (inline) | | | |--60.31%--hypot +20 | | | | | |--8.52%--__hypot_finite +273 | | | | | |--7.32%--__hypot_finite +411 ... --35.34%--_start +4194346 __libc_start_main +241 | |--6.65%--main random.tcc:3326 | /home/milian/projects/kdab/rnd/hotspot/tests/test-clients/cpp-inlining/main.cpp:39 (inline) | /usr/include/c++/6.3.1/bits/random.h:1809 (inline) | /usr/include/c++/6.3.1/bits/random.h:1818 (inline) | /usr/include/c++/6.3.1/bits/random.h:185 (inline) | |--2.70%--main random.tcc:3326 | /home/milian/projects/kdab/rnd/hotspot/tests/test-clients/cpp-inlining/main.cpp:39 (inline) | /usr/include/c++/6.3.1/bits/random.h:1809 (inline) | /usr/include/c++/6.3.1/bits/random.h:1818 (inline) | /usr/include/c++/6.3.1/bits/random.h:185 (inline) | |--1.69%--main random.tcc:3326 | /home/milian/projects/kdab/rnd/hotspot/tests/test-clients/cpp-inlining/main.cpp:39 (inline) | /usr/include/c++/6.3.1/bits/random.h:1809 (inline) | /usr/include/c++/6.3.1/bits/random.h:1818 (inline) | /usr/include/c++/6.3.1/bits/random.h:185 (inline) ... ~~~~~~~~~~~~~~~~ With this patch and `-g srcline` we instead get the following output: ~~~~~~~~~~~~~~~~ $ perf report --stdio --inline -g srcline # Children Self Command Shared Object Symbol # ........ ........ ............ ................... ......................................... # 99.89% 35.34% cpp-inlining cpp-inlining [.] main | |--64.55%--main complex:655 | /home/milian/projects/kdab/rnd/hotspot/tests/test-clients/cpp-inlining/main.cpp:39 (inline) | /usr/include/c++/6.3.1/complex:664 (inline) | | | |--64.02%--hypot | | | | | --59.81%--__hypot_finite | | | --0.53%--cabs | --35.34%--_start __libc_start_main | |--12.48%--main random.tcc:3326 | /home/milian/projects/kdab/rnd/hotspot/tests/test-clients/cpp-inlining/main.cpp:39 (inline) | /usr/include/c++/6.3.1/bits/random.h:1809 (inline) | /usr/include/c++/6.3.1/bits/random.h:1818 (inline) | /usr/include/c++/6.3.1/bits/random.h:185 (inline) ... ~~~~~~~~~~~~~~~~ Signed-off-by: Milian Wolff <[email protected]> Cc: Jiri Olsa <[email protected]> Cc: Yao Jin <[email protected]> Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>

2016-09-12perf hists browser: Fix event group displayNamhyung Kim1-1/+0
Milian reported that the event group on TUI shows duplicated overhead. This was due to a bug on calculating hpp->buf position. The hpp_advance() was called from __hpp__slsmg_color_printf() on TUI but it's already called from the hpp__call_print_fn macro in __hpp__fmt(). The end result is that the print function returns number of bytes it printed but the buffer advanced twice of the length. This is generally not a problem since it doesn't need to access the buffer again. But with event group, overhead needs to be printed multiple times and hist_entry__snprintf_alignment() tries to fill the space with buffer after it printed. So it (brokenly) showed the last overhead again. The bug was there from the beginning, but I think it's only revealed when the alignment function was added.

2016-07-12tools: Introduce str_error_r()Arnaldo Carvalho de Melo1-1/+1
The tools so far have been using the strerror_r() GNU variant, that returns a string, be it the buffer passed or something else. But that, besides being tricky in cases where we expect that the function using strerror_r() returns the error formatted in a provided buffer (we have to check if it returned something else and copy that instead), breaks the build on systems not using glibc, like Alpine Linux, where musl libc is used. So, introduce yet another wrapper, str_error_r(), that has the GNU interface, but uses the portable XSI variant of strerror_r(), so that users rest asured that the provided buffer is used and it is what is returned.

2016-06-22perf hists browser: Introduce struct hist_browser title callbackJiri Olsa1-8/+13
We can now setup title callback for hist_browser, which will be useful in following changes to create customized hist_browsers. This also separates struct perf_evsel dependency out of hist_browser basic code.

2016-03-30perf hists: Fix determination of a callchain node's childlessnessAndres Freund1-1/+1
The 4b3a3212233a ("perf hists browser: Support flat callchains") commit over-aggressively tried to optimize callchain_node__init_have_children(). That lead to --tui mode not allowing to expand call chain elements if a call chain element had only one parent. That's why --inverted callgraphs looked halfway sane, but plain ones didn't. Revert that individual optimization, it wasn't really related to the rest of the commit.

2016-03-10perf hists browser: Check sort keys before hot key actionsNamhyung Kim1-0/+9
The context menu in TUI hists browser checks corresponding sort keys when creating the menu item. But hotkey actions lacks these checks so it can filter using incorrect info. For example, default sort key of 'perf top' doesn't contain 'comm' or 'pid' sort key so each hist entry's thread info is not reliable. Thus it should prohibit using thread filter on 't' key.

2016-03-10perf hists browser: Allow thread filtering for comm sort keyNamhyung Kim1-10/+32
The commit 2eafd410e669 ("perf hists browser: Only 'Zoom into thread' only when sort order has 'pid'") disabled thread filtering in hist browser for the default sort key. However the he->thread is still valid even if 'pid' sort key is not given. Only thing it should not use is the pid (or tid) of the thread. So allow to filter by thread when 'comm' sort key is given and show pid only if 'pid' sort key is given.
