2019-09-25libperf: Add perf_evlist__first()/last() functionsJiri Olsa
Add perf_evlist__first()/last() functions to libperf, as internal functions and rename perf's origins to evlist__first/last.

2019-09-25perf evlist: Adopt backwards ring buffer state enumArnaldo Carvalho de Melo
As this isn't used at all in mmap.h but in evlist.h, so to cut down the header dependency tree, move it to where it is used. Also add mmap.h to the places using it but previously getting it indirectly via evlist.h. Add missing pthread.h to evlist.h, as it has a pthread_t struct member and was getting the header via mmap.h. Noticed while processing a Jiri's libperf batch touching mmap.h, where almost everything gets rebuilt because evlist.h is so popular, so cut down't this rebuild the world party.

2019-09-20perf tools: Move event synthesizing routines to separate headerArnaldo Carvalho de Melo
Those are the only routines using the perf_event__handler_t typedef and are all related, so move to a separate header to reduce the header dependency tree, lots of places were getting event.h and even stdio.h, limits.h indirectly, so fix those as well.

2019-09-20perf tools: Remove debug.h from places where it is not neededArnaldo Carvalho de Melo
Pruning a bit more the includes dependency tree. Building this thing on lots of containers takes time, we better reduce the time per build, each container is doing 6 builds when clang and clang-devel are available, and the plan is to do a 'make -C tools/perf build-test' that have many more. Also helps when doing normal development, as touching some random file will have a much reduced chance of triggering lots of rebuilds.

2019-06-25tools perf: Move from sane_ctype.h obtained from git to the Linux's originalArnaldo Carvalho de Melo
We got the sane_ctype.h headers from git and kept using it so far, but since that code originally came from the kernel sources to the git sources, perhaps its better to just use the one in the kernel, so that we can leverage tools/perf/check_headers.sh to be notified when our copy gets out of sync, i.e. when fixes or goodies are added to the code we've copied. This will help with things like tools/lib/string.c where we want to have more things in common with the kernel, such as strim(), skip_spaces(), etc so as to go on removing the things that we have in tools/perf/util/ and instead using the code in the kernel, indirectly and removing things like EXPORT_SYMBOL(), etc, getting notified when fixes and improvements are made to the original code. Hopefully this also should help with reducing the difference of code hosted in tools/ to the one in the kernel proper.

We can just use the 'field width' for the %s used to print the alignment, this way we'll get the same result without requiring having a variable with just lots of space chars.

2019-06-18perf build: Handle slang being in /usr/include and in /usr/include/slang/Arnaldo Carvalho de Melo
In some distros slang.h may be in a /usr/include 'slang' subdir, so use the if slang is not explicitely disabled (by using NO_SLANG=1) and its feature test for the common case (having /usr/include/slang.h) failed, use the results for the test that checks if it is in slang/slang.h. Change the only file in perf that includes slang.h to use HAVE_SLANG_INCLUDE_SUBDIR and forget about this for good. On a rhel6 system now we have: $ /tmp/build/perf/perf -vv | grep slang libslang: [ on ] # HAVE_SLANG_SUPPORT $ ldd /tmp/build/perf/perf | grep libslang libslang.so.2 => /usr/lib64/libslang.so.2 (0x00007fa2d5a8d000) $ grep slang /tmp/build/perf/FEATURE-DUMP feature-libslang=0 feature-libslang-include-subdir=1 $ cat /etc/redhat-release CentOS release 6.10 (Final) $ While on fedora:29: $ /tmp/build/perf/perf -vv | grep slang libslang: [ on ] # HAVE_SLANG_SUPPORT $ ldd /tmp/build/perf/perf | grep slang libslang.so.2 => /lib64/libslang.so.2 (0x00007f8eb11a7000) $ grep slang /tmp/build/perf/FEATURE-DUMP feature-libslang=1 feature-libslang-include-subdir=1 $ $ cat /etc/fedora-release Fedora release 29 (Twenty Nine) $ The feature-libslang-include-subdir=1 line is because the 'gettid()' test was added to test-all.c as the new glibc has an implementation for that, so we soon should have it not failing, i.e. should be the common case soon.

2019-03-11perf ui browser: Fix ui popup argv browser for many entriesAndi Kleen
Fix the argv ui browser code to correctly display more entries than fit on the screen without crashing. The problem was some type confusion with pointer types in the ->seek function. Do the argv arithmetic correctly with char ** pointers. Also add some asserts to find overruns and limit the display function correctly. Then finally remove a workaround for this in the res sample browser. Committer testing: 1) Resize the x terminal to have just some 5 lines 2) Use 'perf report --samples 1' to activate the sample browser options in the menu 3) Press ENTER, this will cause the crash: # perf report --samples 1 perf: Segmentation fault -------- backtrace -------- perf[0x5a514a] /lib64/libc.so.6(+0x385bf)[0x7f27281b55bf] /lib64/libc.so.6(+0x161a67)[0x7f27282dea67] /lib64/libslang.so.2(SLsmg_write_wrapped_string+0x82)[0x7f272874a0b2] perf(ui_browser__argv_refresh+0x77)[0x5939a7] perf[0x5924cc] perf(ui_browser__run+0x39)[0x593449] perf(ui__popup_menu+0x83)[0x5a5263] perf[0x59f421] perf(perf_evlist__tui_browse_hists+0x3a0)[0x5a3780] perf(cmd_report+0x2746)[0x447136] perf[0x4a95fe] perf(main+0x61c)[0x42dc6c] /lib64/libc.so.6(__libc_start_main+0xf2)[0x7f27281a1412] perf(_start+0x2d)[0x42de9d] # After applying this patch no crash takes place in such situation.
